KATO, Junko. Institutions and Rationality in politics: Three Varieties of Neo – Institutionalist. British Journal of Political Science, v 26, n. 4, p 553-582, oct., 1996. Review Article: Institutions and Rationality in Politics - Three Varieties of Neo-lnstitutionalists JUNKO KATO* The driving force behind the production of new studies in political science is a focus on political institutions - the new institutionalism. This recent shift in the dominant approach in political science has brought increasing scholarly interest in institutions [Nota 1] and ushered in an active debate about certain central concepts, such as the state [Nota 2]. Two major controversies revolve around the new institutionalism. The first is between supporters and sceptics of the utility of this approach in political science. While the advocates claim that the focus on political institutions will shed new light on underexplored or even neglected aspects of politics, the sceptics doubt the novelty of the insights and are thus reluctant to promote this approach at the expense of existing approaches in political science [Nota 3]. The second dispute, which has been less salient, but is becoming more important as scholarly interest in institutions increases, is concerned with how the new institutionalism can analyse the relationship between individuals and institutions. In this argument, three distinct groups can be identified. The first group employs primarily traditional methods of political science research, especially historical investigation and qualitative analysis with a Page 554 renewed focus on institutional changes and dynamics. The alleged novelty of this first approach, therefore, lies not in its research methodology, but in its broadened perspectives of institutions which include factors such as culture, norms and routines. The second group is composed of rational choice theorists who attempt to incorporate institutional constraints upon individual behaviour into their original approach, which is based on an assumption of economic rationality. Their approach is 'new' in the sense that they add institutional factors to the analytical framework of micro-economics or public choice theory. The third group is least well known and often confused with the second group. They use the concept of bounded rationality, as presented by Simon [Nota 4] and consider institutions to be organizational contexts in which individual rational behaviour is cultivated and promoted. The three groups are often confused with each other. One reason for this is that each makes its own claim for the importance of institutions independently of the other groups' claims. Skocpol sets the agenda for 'bringing the state back in' only for the first group of new institutionalists [Nota 5]. McCubbins makes a convincing case for incorporating institutional factors into rational choice perspectives [Nota 6]. In the third category, North analyses the relationship between institutional change and economic performance and shows its strength by using an approach based on bounded rationality [Nota 7]. Recently, some scholars have been interested in comparing these different approaches [Nota 8]. In contrast to existing comparisons of neo-institutionalism, this article aims to clarify the merits of the various new institutionalist approaches and narrow their disagreement on the question of the relationship between political institutions and individual rational behaviour. A central aspect of the disagreements among the three approaches is closely related to their different Page 555 perspectives on individual rationality. A deep chasm divides those who consider the assumption of individual rationality an important component of institutional analysis and those who see it as a misperceived postulate diverting our attention from institutions. Scholars relying on the historical method and qualitative sociopolitical analysis (those in the first group) regard the assumption of individual rationality as incompatible with an institutional focus, and, thus, are sceptical of the other approaches. By contrast, rational choice theorists in the second group stress that retaining the economic rationality assumption is the best way to maintain a unified and cohesive analytical scheme of institutional analysis. The third approach, based upon bounded rationality, seeks a middle ground between the socio-historical approach and the rational choice approach. Its assumption of human rationality enables one to regard institutions or organizations [Nota 9] as possible environments in which the rational behaviour of individual actors is promoted. My ultimate aim is to provide some bridge between those who support and those who oppose employing the rationality assumption. The first part of this strategy is to clarify the different emphases in institutional analysis between the socio-historical approach and the rational choice approach. Although these approaches have distinct strengths in identifying different aspects of the interaction between institutions and individuals, I do not propose a synthesis between the two competing approaches. Rather, I will argue that the coexistence of the two approaches serves to broaden our understanding of politics, especially in comparative studies. I make a special effort not to overextend criticisms presented by one approach to another. More specifically, I intend to qualify, on the one hand, the socio-historical criticism of institutional analysis using the rationality assumption; and, on the other, the rational choice criticism of the limited generality of the socio-historical approach. I will then introduce the third approach as a middle way between these two approaches and suggest that discussions about the meaning of political institutions and individual rationality can be made more productive by using this aproach. DIFFERENT APPROACHES TO INSTITUTIONS The first group of new institutionalists includes a broad range of political scientists, as well as some sociologists and historians. With a small number of exceptions, those using the socio-historical approach regard the assumption of individual rationality or rational behaviour in politics as incompatible with an institutional focus. I will argue that criticism of the rational choice approach by Page 556 the first group often exaggerates the limitation of the rationality assumption. To this end, I will first compare and contrast the socio-historical and rational choice new institutionalisms. Both the socio-historical institutionalists and the rational choice new institutionalists are concerned with the question of how institutions shape political behaviour and outcomes [Nota 10]. These approaches emerged from a reaction to the indifference to political institutions during the behaviourist era of the 1950s and 1960s. Major proponents of different new institutionalist approaches criticize the preceding approaches. For example, Skocpol has presented a clear antithesis to the pluralist, structural-functionalist and Marxist literatures, which she alleges were dominant during this period, and has proposed a new institutional interest, focusing particularly on the state [Nota 11]. March and Olsen contrast their institutionalist approach with contextualism, reductionism, utilitarianism, instrumentalism and functionalism during the same period [Nota 12] Rational choice theorists, such as Ordeshook, also define a new institutionalism as 'an effort at recombining behaviourist research with more traditional concerns of political science', namely institutions [Nota 13]. The second common point between the socio-historical and rational choice institutionalists is the inclusion in the analysis of both formal rules and organizations and informal routines and procedures [Nota 14]. Despite this similarity, however, these two institutionalist positions are distinguishable, especially in the way they interpret and analyse individual behaviour in institutions. Steinmo and Thelen make the most clear-cut distinction in this respect [Nota 15]. According to them, the rational choice approach relies on 'a "universal tool kit" that can be applied in virtually any political setting', that is, a logical framework based on the assumption of utility maximization of selfinterested individuals; and it considers an institution as 'a strategic context, imposing constraints on self-interested behaviour'. By contrast, historical institutionalists find that Page 557 reliance on such a deductive logic based on individual rationality restricts their interests in institutions. Thus, 'rather than deducing hypotheses on the basis of global assumptions and prior to the analysis, historical institutionalists generally develop their hypotheses more inductively, in the course of interpreting the empirical material itself.[Nota 16]. Rational choice studies apply the assumption of utility maximization, or some approximation of it, to the analysis of political actors. But, which political actor' s preference or interest is of primary importance differs from one rational choice perspective to another. Different assumptions, concerning, for example, the domination of bureaucratic interests over a popular mandate or the effectiveness of political control over bureaucracy, can lead to completely different conclusions about policy outcomes. Using the former assumption, Niskanen,[Nota 17] and Brennan and Buchanan [Nota 18] maintain that the preferences of constituents of the state, especially bureaucrats who are free from popular mandates, dominate decisions on public policy. However, other public choice literature emphasizes the link between public preference and policy decisions and presents rational choice perspectives that focus on incentives provided by politicians' desire for re-election [Nota 19]. In terms of macro-level concerns, the rational choice approach permits one to analyse various consequences of rational behaviour such as collective action problems represented by Olson's work on interest groups,[Nota 20] the prisoners' dilemma situation applied both to international and domestic politics, party competition as formulated by Downs,[Nota 21] and so on. The novelty of rational choice new institutionalism lies in the analysis of the effects and influences of institutions, especially the analysis of whose interests or preferences prevail in public policy or social decisions. The literature explores the relationship between institutional contexts or 'structures' for decision making and rational individual behaviour defined a priori. For example, the rational choice literature in American politics is especially concerned with how politicians who desire re-election represent the interests of constituencies under the constraints of the institutionalized decision-making procedures and committee system of Congress [Nota 22]. It also investigates agenda Page 558 control and compliance with rules within the Congress and explores the reason why congressmen representing various interests can decide on specific legislation. Thus Moe surveys this rational choice literature in American politics as a 'positive theory of institutions'[Nota 23]. Rather than predetermining a unit of analysis such as a rational individual, studies using the socio-historical approach are the product of research that takes organizations or institutions as primary subjects. Among socio-historical institutional studies, I distinguish those that reflect a state-centred view, those that examine state-society relations, and those that focus on the more basic elements that constitute institutions, that is, routines, rules, norms, values and ideas [Nota 24]. Because attempts at 'bringing the state back in' belong to studies of the statecentred view, Skocpol [Nota 25] reviews many works including those by Evans, Krasner, Nordlinger, Skocpol, Stepan, Skowronek, Tilly and Trimberger [Nota 26] Page 559 Studies using this perspective tackle the problems of state autonomy directly (that is to what extent state action is independent of social pressure), and of state capacity (that is, to what extent the state contributes independently to determining policies or political changes). By contrast with the state-centred view, works that examine state-society relations aim to elicit a pattern of interaction between the state (in most cases, bureaucracy) and society (social classes or interest groups whose interests are represented by politicians), and associate this pattern with resulting policy outcomes or changes. Many works about interest groups and those about economic policies adopt this view. For example, Schmitter and Lehmbruch employ the concept of corporatism to investigate modes of representation of social interests in the state policies;[Nota 27] Gourevitch, Haggard, Hall, Hart, Katzenstein, and Zysman compare and contrast economic performance of different countries in terms of the state-society relationship focusing on the state structure [Nota 28]. Thirdly, some socio-historical institutionalists present much smaller units of analysis, in the form of norms, rules and ideas comprised in institutions [Nota 29] For example, Elster has shifted from his interest in game theory and has begun to pay more attention to social norms [Nota 30]. Hall tries to incorporate elements of policy ideas into the socio-historical analysis of the policy-making process [Nota 31], and Page 560 March and Olsen argue the importance of norms and rules in organizational settings [Nota 32]. Each of the socio-historical studies of institutions is unique and original, but many recent studies share several common perspectives about politics and political behaviour [Nota 33]. They try to identify the institutional influences that political actors are likely to follow, such as the organizational interests, ideologies or value orientations peculiar to certain institutions, rather than to define them as aggregations of individual interests and preferences. They do not define individual interests and preferences independently of institutions. Nor do they relate political behaviour directly to individual interests and preferences. In order to generalize their findings about different institutions, most studies rely on a comparative analysis of political processes or the comparison of historical cases. Thus, these studies reject the use of a deductive method to analyse individual behaviour that can be applied to different organizations and institutions. Consequently, they are cautious about employing a concept of rationality that implies a behavioural pattern based on a means-ends calculus or even goal-oriented behaviour in general. The discussion thus far has clarified why proponents of the socio-historical approach often regard the institutional analysis of the rational choice approach as limited by a narrowly-defined rational action postulate. How extensively can this criticism be applied to the rational choice approach? The rationality concept in economics on which the rational choice approach is based is utility maximization; it defines a behavioural pattern that links means to ends [Nota 34]. The concept of economic rationality is purely instrumental and formal in the sense that it denotes a choice of the best means for whatever goals individuals pursue. While socio-historical studies regard institutions as a primary subject of analysis, the rational choice approach focuses on individual rational behaviour and analyses its relationship with institutions. This contrast is often interpreted as a superior or inferior method of institutional analysis rather than a difference in the way to examine institutional factors. Socio- historical institutionalists tend to believe that the incorporation of a strong Page 561 behavioural assumption, such as in the rational choice approach, deflects one's attention from the institution as a whole; in contrast, rational choice theorists contend that the application of a common behavioural assumption, such as a rational choice, is the best way to distinguish institutional effects which may lead to strikingly different political outcomes across systems or countries. There are three reasons to believe that the conflict between the two approaches is exaggerated. First, it is possible to use the factors such as rules, routines and norms embedded in institutions with the postulate of individual rational calculation in the explanation on policy outcomes. For example, Ostrom argues that rules and social norms do not comprehend all forms of behaviour appropriately accepted in certain social contexts, and they thereby leave a significant amount of behaviour to independent individual decisions - most plausibly, rational ones [Nota 35]. Secondly, on the question of institutional emergence, socio-historical and rational choice institutionalism may not diverge as much as they appear to. The socio-historical approach considers the emergence of institutions to be the result of adopting a certain norm or of a historical consequence, while the rational choice approach is concerned with the rational basis of institutional emergence. For example, March and Olsen emphasize institutional emergence and transformation driven by the logic of appropriateness;[ Nota 36] and the joint essays by Steinmo and Thelen explain how historical contingencies affect the formation of policies and political organizations [Nota 37]. In contrast, the rational choice approach pays attention to the calculation of self-interest by individuals. Ostrom contends that rational individuals choose institutions for selfgovernance using the information about prospective rules as well as costs and benefits accompanied by these rules [Nota 38]. More specifically, she shows that such voluntary self-organiza- tion, instead of coercive state action and market mechanisms, may well solve the collective action problems of pooled resources. While the above rational choice explanation of the origin of institutions appears to contradict the socio-historical approach, the recent approach within rational choice certainly serves to bridge this gap because it emphasizes the process of institutional emergence. For example, Knight focuses on the rational individual's concern with the distributional consequence of institutions, but he explains the emergence of these institutions as a by-product of distributional conflicts rather than as a result of individuals' seeking the collective benetits expected from them [Nota 39]. Knight shows that the rational choice explanation of institutional emergence does not necessarily presume intentional individual Page 562 behaviour to seek a certain goal [Nota 40]. Such a new approach shows that rational choice neo-institutionalism may be more compatible with sociohistorical neo-institutionalism. Lastly and most importantly, it is possible to maintain that a socio-historical approach can also involve the assumption of rational behaviour. For example, the rationality assumption can be an indisputable part of a statist approach, especially one which focuses on autonomous and self-interested officials who have secure tenure in the state. Nordlinger [Nota 41] correctly highlights a close parallel between the statist position and the monopoly bureau model of Niskanen [Nota 42] which contends that rational bureaucrats maximize their budgets at the expense of the welfare of sponsors (legislatures and, ultimately, voters). Both this statist view (in socio-historical institutionalism) and the monopoly bureau model (in the rational choice approach) assume that bureaucratic interests dominate over the social interests represented by party politicians. Thus, in both approaches, bureaucratic interests determine most policy outcomes at the expense of an electoral mandate. The historical studies that regard the state as an autonomous organization also define what interest policy makers or rulers are pursuing and ultimately attribute the direction of state behaviour to their interest. For example, Skocpol treats the state as a unitary autonomous actor in her comparative historical study of the French, Russian and Chinese revolutions,[Nota 43] and presents the idea that 'one (hidden or overt) feature of all autonomous state actions will be the reinforcement of the prerogatives of collectivities of state officials' [Nota 44]. In other words, she hypothesizes that state action cannot be 'disinterested' given its incumbents' intents, though she admits the possible inconsistency of such an action and refrains from asserting the rationality of constituents of the state [Nota 45]. In this way, when self-interested behaviour is taken for granted under the guise of a unitary or autonomous state organization, state-centred views may be interpreted as being compatible with the rational choice approach. If this is so, Page 563 the real dispute between the socio-historical and rational choice approaches is over the issue of methodological individualism rather than the rationality assumption itself.46 If one rejects an epistemological commitment to methodological individualism, one tends to understand the state only in its relationship with social processes or social organizations. Mitchell, who regards the state as a set of disciplinary effects, exemplifies this anti-deductionist nature of the socio-historical approach; he argues that the state should be analysed as a structural effect that works in a distinct dimension of society [nota 47]. However, Mitchell's approach, which refuses to regard the state as a separate entity, is controversial even among socio-historical institutionalists [nota 48]. The above discussion shows that socio-historical institutionalism often includes the individual rationality assumption as an element of institutional analysis though it refuses to develop the deductive logic starting from such a simple assumption. This point will be confirmed in the next section with reference to the comparative literature. SOCIO-HISTORICAL AND RATIONAL CHOICE APPROACHES: CONTRIBUTIONS TO COMPARATIVE STUDIES While the critics of the rational choice approach tend to reject its utility altogether, some rational choice theorists are also uncompromising in their view of other approaches. Proponents of the approach contend that the individual rationality assumption is useful for making generalizations about intentions observed in specific cases, especially for finding an equilibrium in political interactions as a consequence of decisions [nota 49]. This defence of the rational choice approach often leads to a dismissal of other approaches. For example, Riker labelled as 'hermeneutics' the approach that emphasizes concrete circumstances or cultures in which decisions are made, and he argued that, within such an approach, one interprets intentions of political actors specific to the circum- stances around them and 'confines social studies entirely to the interpretation of specific events' [nota 50]. Here, the disagreement between critics and advocates of rational choice widens into a chasm which it is impossible to bridge. My position differs from the two extremes of full-blown critics and advocates of the rational choice approach. Instead, I will argue that the socio-historical approach and the rational choice approach have different merits. More specifically, I will demonstrate that each approach is suitable for a different purpose. This point is especially clear if one examines the utilities of the two approaches in comparative studies, where scholars are required to make Page 564 certain generalizations about political phenomena or to find rules across different countries and political systems. The Rational Choice Approach in Comparative Studies Let me start with reviewing the rational choice comparative literature. Comparative studies using the rational choice approach are still at their early stages, but the rational choice theorists' position in such comparative inquiries is clear: individual behaviour can be regarded as rational in so far as one is concerned to examine major social and political consequences [nota 51]; and thus, the fundamental principles of political behaviour are the same across different political systems despite seemingly different configurations of institutions and political phenomena [nota 52]. I will illustrate this position by using a famous Downsian formulation which explains two-party and multi-party dynamics [nota 53]. In this formulation, the political parties in a two-party system behave quite differently from those in a multi-party system. But, this divergence is not considered to be the result of different behavioural principles at the party level. There is a common assumption about party behaviour that parties make policies to maximize the votes obtained in elections. The divergence between different party systems is the result of an adaptation, based on a common behavioural principle, to different circumstances. Adopting such a behavioural assumption is quite useful when one attempts to illuminate the effects of institutions on individuals, because individuals are assumed to respond to the same influences from their environments in the same way, that is, rationally. This point is clear if we observe the application of the rational choice approach to a comparative study of traditional and moder societies, especially the pre-industrial and industrial ones. Through the eyes of observers in industrialized democracies, African agrarian societies appear quite distinct given their resistance to market economies and their difficulties in transition to democratic polities. Bates began his career as an African specialist devoted to a cultural explanation that emphasized the indigenous characteristics of Africa, but he now argues for the utility of the rational choice approach - especially the collective-choice approach - to a developing society [nota 54]. One of the Page 565 most crucial differences between the cultural and rational choice approaches lies in whether to regard individual members of a society as having psychological characteristics distinct from those found in industrialized societies. Cultural explanations characterize members of a society by their special social psychological traits, and relate a society's low level of economic and political development to individual characteristics particular to its culture and social values [nota 55]. The choice-theoretic approach, according to Bates, considers the fundamental pattern of individual behaviour as basically the same, i.e., rational, and explains divergent political and economic consequences by influences over individuals of political institutions that are particular to the society [nota 56]. The picture that emerges from the choicetheoretic approach is just the opposite of the one from the cultural explanation. That is, 'behavior that has been interpreted to be the result of tradition, passed on by socialization and learning, can instead be interpreted to be the result of choice' [nota 57]. More specifically, individuals in agrarian societies in Africa, if they resist modernization, 'choose to do so' instead of suffering from misinformation or ignorance. Application of the assumption of individual rationality, though it is not very strict in Bates's framework, leads to a successful demonstration of the similarities in the pattern of individual behaviour across different societies and to a refutation of the uniqueness of the case studied [nota 58]. As Bates argues, however, a choice-theoretic approach such as the rational choice approach is not necessarily incompatible with the explanation that focuses on specific cultural values and distinctive institutions. While refusing to explain every phenomenon in agrarian Africa by characteristics of its native society, Bates appreciates the importance of 'the particularities of specific culture' or 'significance of values and institutions'. What is to be examined 'is the manner in which these factors systematically shape collective outcomes' [nota 59]. In his view, the rational choice approach provides a powerful tool to connect individual behaviour to political and economic phenomena at the level of a society or country, and to explain how rational individuals adjust to distinct institutional settings and specific cultural entities. Bates's approach is one of rational choice; but he also contends that maintaining the behavioural assumption of individual rationality and appreciating the distinct influences of specific circumstance over individuals are equally Page 566 important. This point is also demonstrated by Little [nota 60]. He stipulates that the rational choice approach 'provides a basis for social explanation in a wide variety of cultural contexts and may support significant cross-cultural generalizations' [nota 61]. At the same time however, he is conscious of the limitations of the rational choice framework, with its oversimplified and abstract characterization of rational agents and structure, and indifference to the roles of norms and values. He suggests that it is necessary 'to pay more attention to the institutional framework within which choice takes place' and to the roles of values and norms in individual decision making [nota 62]. From this position, the distance between an approach based on the rationality assumption and one not so based, for example, socio-historical new institutionalism, may not be very great. Between the two approaches, there is a shift in scholarly interest: from one eliciting the general pattern of individual behaviour to one characterizing institutions that constitute environments for individuals. Interestingly, Williamson observes this kind of shift in scholarly interests between neoclassical economics based on a rigorous rationality assumption and institutional economics based on a weak assumption of rationality, that is, bounded rationality. He emphasizes that 'comparative institutional analysis commonly involves an examination of discrete structural alternatives for which marginal analysis is not required' [nota 63]. I would like to clarify this point by following Simon's discussion of the modification of the rationality assumption [nota 64]. According to Simon, in 'analyses aimed at explaining institutional structure, maximizing assumptions play a much less significant role than they typically do in the analysis of market equilibria' [nota 65]. This is because 'they are not focused on, or even much concerned with ... how equilibrium is altered by marginal shifts in conditions'; rather they are 'focused on qualitative and structural questions, typically on the choice among a small number of discrete institutional alternatives' [nota 66]. Closely paralleling this reasoning, one can speculate as to why some employ the socio-historical analysis of institutions without using the rationality assumption and why others apply the rationality postulate to the empirical analysis, though not in a very strict way. To investigate this point, consider two scholars who study different areas from a comparative institutional perspective. Page 567 Bridging the Gap between the Socio-Historical and Rational Choice Comparative Studies Peter Hall, in his comparative study of Britain and France [nota 67] presents a comprehensive concept of 'institutions', which refers to 'the formal rules, compliance procedures, and standard operating practices that structure the relationship between individuals in various units of the policy and economy'. In his analysis of the empirical cases of Britain and France, Hall focuses on 'the relational characters of institutions', especially, the influences of the organizations [nota 68] of capital, labour and state on the economic policy choices of the two countries, while also paying close attention to external economic factors. He examines the rational choice approach [nota 69] as an alternative to his own institutional approach [nota 70]. He includes in the rational choice approach one branch of organization theory, which employs a conception of bounded rationality [nota 71]. He pays special attention to this organization theory as a promising alternative to his approach. However, he rejects the use of this approach in the close examination of institutions. He argues 'a great deal of organization theory has been devoted to the discovery of laws applicable to the operation of organizations' and 'more must be done to associate particular patterns of rationality with specific organizational attributes' [nota 72]. Here, Hall decides not to use the rationality assumption because he intends to analyse different organizations, that is, capital, labour and state, by different kinds of logic. He maintains that organization theory applies the same logic to the analysis of these organizations. And such standardized treatment is obviously not suitable for his purpose, which is to specify the relationships between these organizations in the two countries in question and to distinguish the countries in terms of their relationships. Stephan Haggard's comparative study of newly industrializing countries (mainly in East Asia, but also in Brazil and Mexico) [nota 73] is a good example of starting with the rationality assumption applied to individuals and developing the study into a socio-historical analysis. His approach is characterized as Página 568 state-centred, although he also includes for consideration factors that represent international shocks and pressures as well as configurations of social groups. Instead of focusing on the relationship of different institutions as Hall does, Haggard pays close attention to the interests of political elites as constituents of the state. He examines how, and to what extent, international crisis or change as well as social groups' demands are interpreted by elites and then translated into specific policies. Thus, his state-centred view is one that is very close to the rational choice approach centred on the monopoly power of bureaucracy which I have already discussed relying on Nordlinger. (Nota 74) Haggard himself acknowledges this: 'The emphasis I give to politically motivated choice by state actors falls broadly within the realm of rational-choice theorizing, and I have learned from this strand of work'. (Nota 75) Haggard starts from the assumption that policy-makers rationally seek power, but at the same time he puts 'great emphasis on the institutional context within which political choice takes place'. He stresses the fact that 'political elites differ in their organizational capabilities and the instruments they have at their disposal for pursuing their goals'. (Nota 76) He is especially interested in situations in which the distinctiveness of institutional settings across countries leads equally rational policy-makers to different policy choices. A subtle balance between the socio-historical emphasis and the attention to the individual policymakers is the reason why Haggard's approach clarifies the distinct policy responses among the East Asian Newly Industrialized Countries (NICs) which have been commonly characterized as successful examples of industrialization. In this respect, Haggard succeeds in bridging the gap between the first and second groups of new institutionalists. This compatibility between the rationality postulate and the socio-historical analysis demonstrated by Haggard casts doubt on an easy distinction between the socio-historical and rational choice new institutionalism in comparative studies. The assumption of individual rationality often seems the focal point of the dispute between the two groups, but as Haggard's work implies, sociohistorical analysis is not necessarily incompatible with the employment of the rationality assumption. This finding parallels the theoretical argument at the end of the previous section: the real difference between socio-historical and rational choice institutionalism arises from their epistemological attitude to the deductive logic which derives from a strict application of the rationality assumption. Some socio-historical new institutionalists clarify the behavioural postulate prior to analysis, but do not extend the application of such an assumption all the way in the analysis. A typical example of such an approach is Rogowski's cautious but persuasive presentation of the influence of trade on domestic political cleavages in cases Página 569 varying from the ancient period to the nineteenth and twentieth centuries. (Nota 77) Rogowski presents a set of three simple assumptions about political behaviour. First, those who gain from trade try to maintain the status quo while those who are harmed by exposure to the same situation try to change it; secondly, economic gainers increase their political power; thirdly, the economic beneficiaries of trade attempt to institutionalize the mechanism in order to continue the current favourable conditions. (Nota 78) The close parallel between economic capability and political power and the primacy of selfinterested behaviour (Nota 79) supports an examination of the historical development of political cleavages. What he demonstrates is the link between conflicting domestic interests in the trade issue and political cleavages, a link which has otherwise been obscured by other factors such as political culture, religion, tradition, social heritage and custom, and political contingencies. He avoids overplaying the impact of trade on domestic politics and does not assert that trade determined most of the configurations of domestic social alliances of the countries which he studied. Despite this modesty, Rogowski's work convincingly shows that a rational response to trade contributes to a specific institutionalization of political alliance in countries that had previously been examined primarily by socio-historical studies such as Gerschenkron (Nota 80) and Moore. (Nota 81) He critically examines these alternative explanations of the emergence of domestic political alliances while showing empirically the persuasiveness of his argument. In this respect, Rogowski's approach contrasts well with the rational choice analysis of Przeworski.(Nota 82) Przeworski uses a game theoretical formulation to explain the institutional consolidation of democracy. He specifically focuses on conflicting social forces which try to capture the transition to democracy to advance their political advantages. He regards the transition as a process in which their conflicts over a basic institutional design continue. At the same time, he relates democratic transition with reform to a market-oriented economy. What is to be noted here is that Przeworski uses the recent transitions to democracy and market economy in Eastern Europe and Latin America to support his theory rather than using the framework to explain these cases. Though both Rogowski and Przeworski start their socio-historical analysis from the rationality assumption, they differ in how they draw their conclusions and justify their arguments. Rogowski's work is based firmly on the assumption of Página 570 rational behaviour, but his argument is closely supported by inductive reasoning and empirical observation. (Nota 83). An approach such as Rogowski's opens' the possibility that the rationality assumption will be abandoned if it does not approximate a real situation. Such an example is found in Steinmo's (1993) comparative study of the development of contemporary taxation in Sweden, Britain and the United States [Nota 84]. Steinmo attempts both an analysis of individual rational behaviour and a socio- historical analysis. In contrast with Rogowski, however, Steinmo finds little point in using the rationality assumption and shifts the emphasis to institutional analysis. Steinmo does not deny that citizens, party politicians and bureaucrats are rational in the sense that they try to pursue their own interests. But, at the same time, he emphasizes that they are not necessarily well-informed because of the limitations of their capacity and affordable time (especially in the case of citizens); and that 'people do not have a single definable and stable hierarchy of preferences that can or should be used to decide between competing policy choices' [Nota 85]. The recognition of the ambiguities of the preferences and the decisions of political actors shifts the focus of analysis to political institutions which constitute the context in which policy decisions and behaviour take place. Steinmo does not deny the existence of a common behavioural pattern across countries and contends that 'both citizens and elites in Sweden, Britain and the United States would make highly similar decisions if offered similar choices'[Nota 86]. However, 'the real choices in one country are not likely to be offered in the same way that they are in another country ... because the institutions through which they are offered differ' [Nota 87].Thus, political institutions which were founded on the basis of historic compromise in these countries from 1918 to 1945 still have sweeping influences over tax policy outcomes, though they have been changing and are expected to change in the future [Nota 88]. Rogowski's and Steinmo's attitudes towards the rationality assumption differ: Rogowski finds that trade has a persistent impact on the domestic politics of interest-seeking behaviour, while Steinmo detects no major impact from rational political behaviour over tax policy outcomes [Nota 89]. Like Rogowski, Page 571 Steinmo pays close attention to individual rational behaviour and carefully examines its meaning. But, based on the findings in his comparative study of tax politics in three countries, Steinmo explicitly denies any epistemological and methodological commitments that aim to establish a universal law of human behaviour [Nota 90]. What I have argued in this section is quite simple. Researchers choose a certain approach from several alternatives, based on their interest in their subjects and the purpose of their investigation. This attitude is also observed in their choice between two different new institutionalist approaches - the sociohistorical approach and the rational choice approach. The rational choice approach explains individual behaviour relating to institutions, but it distinguishes the logic of individual behaviour from that of institutional characteristics. This distinction avoids tying individual behaviour to specific institutions and serves to emphasize the fundamental pattern of individual behaviour across different institutional settings. However, this is exactly the reason why some socio-historical institutionalists such as Hall and Steinmo refrain from using the rationality assumption and employ a more qualitative analysis of institutions. In other words, researchers who are overtly concerned with connecting political choices with the distinct institutional settings of each country, consider the common patterns of behaviour which may link individual decisions to institutional settings across countries a secondary interest. Thus, in terms of scholarly emphasis, both the socio-historical approach and the rational choice approach are equally justified with no need to dismiss the other. The Issue of Epistemological Commitment to Methodological Individualism Despite the compatibility described above between these new institutional approaches, commitments to methodological individualism may still remain an issue on which socio-historical new institutionalism and rational choice new institutionalism disagree. While deduction based on methodological individualism is a theoretical foundation of rational choice comparative studies, the sociohistorical new institutionalists may argue that this theoretical core of the rational choice itself is incompatible with robust empirical analysis. The key Page 572 issue here is to what extent and in what way the rational choice comparative studies can leave room for empiricism. To answer this, one needs to find comparative literature that apparently employs methodological individualism and to examine to what extent and in what way it can go hand in hand with empiricism. A good example of such literature is Margaret Levi's analysis of the state's power to produce revenue [Nota 91]. She explains revenue production by the presence of predatory rulers who aim to satisfy their personal objectives by maximizing revenue. Levi's analysis is clearly based on methodological individualism and deduction. She focuses on the self-interested behaviour of rulers and explains how institutions are arranged to maintain a half-voluntary compliance with state power to maximize revenue. The rulers' bargaining power, their ability to avoid transaction costs and the durability of their rule are the factors that constitute the constraint on their choice of a revenue system through which they try to capture as much revenue as possible. Alternatively, the rulers attempt to increase their bargaining power with the governed or their constituencies, lower the transaction costs that they incur when collecting revenue (that is, costs of bargaining, agency costs, and so on), and keep lower discount rates of the present value of revenue in the future. This perspective shows the dynamic interaction between micro-level factors (which define the rulers' rational behaviour) and macro-level factors (which characterize the resulting revenue policies) and is consistent with the process analysis that uses historical material. Thus Levi can apply her theory to such diverse cases as Republican Rome, medieval and Renaissance France and England, eighteenthcentury Britain, and twentieth- century Australia, and support her argument with ample empirical evidence. Another example of a rational choice comparative study is Geddes's work which seeks to explain why some Latin American countries have engaged in administrative reforms to create competent bureaucracies and others have not [Nota 92]. She considers that reform involves the supply of collective goods to people in developing countries who desire economic development and essential govern- ment services through well-organized bureaucratic systems. According to her argument, politicians face a dilemma when they attempt to implement reforms that are beneficial for the long-term development of countries and are desired by their constituencies. This is because they need to give up political resources (that is, clientelism, established personal connection with officials, and so on) which they currently get from the existing systems. Politicians become political entrepreneurs who institute reform only when the benefits outweigh the costs of implementing them. This means that a substantial number of politicians must be continuously encouraged with incentives to boost their latent interests to provide a public good. What is to be noted in Geddes's framework is that the Page 573 politicians' incentives to provide a public good (that is, competent administrative capacity expected from the reforms) are primarily shaped by political institutions such as election systems, party systems, organizations of executive branches and so on. In her framework, the institutional setting of the country is not just a constraint on politicians' rational behaviour, rather it provides the incentives for politicians as well as the solution for collective action problem. This is the reason why she can point out institutional conditions which serve to introduce and extend administrative reforms based on historical and empirical observation. For example, when access to patronage resources is evenly divided among major parties (such as in stable two-party systems), reforms are more likely to be introduced and 'presidents are more likely to help build administrative competence in stable, well-institutionalized, less fragmented, and more disciplined party systems' [Nota 93]. Levi's and Geddes's works suggest that methodological individualism and deduction do not necessarily preclude the production of high quality empirical works. In both studies, the assumed behaviour of a rational individual is deeply embedded in institutional circumstance. This reminds us of the importance of knowing under what conditions and in what context rational behaviour takes place. A ramification of this point provides a key to understanding why the third group of new institutionalists employs a concept of bounded rationality distinct from economic rationality conventionally conceived in the rational choice framework. To explore this issue, the next section will first introduce a distinction between the concepts of economic and bounded rationality. Then, I will consider the utility the bounded rationality concept has in comparative politics. ECONOMIC RATIONALITY AND BOUNDED RATIONALITY: THE SECOND AND THIRD GROUPS OF NEW INSTITUTIONALISTS The most popular criticism of the rational choice approach is that the rationality assumption is too strict and unrealistic to apply to real situations. A criticism of rational choice perspectives involves two related but still distinct points: (1) the realism of the rationality assumption, that is, the fit between the rationality assumption and real situations in general; and (2) the possibility that such a simple account of individual rationality may ignore the complexities of incentives in specific real situations. There are two possible ways to defend the rationality assumption in the face of such criticisms. One is to defend its general applicability, that is, to support the utility of the assumption in all aspects of political life. This position ignores the criticism of the 'un-realism' of the rationality assumption in order to emphasize its utility as the foundation for coherent theory. Another defence is more modest and claims that the rationality assumption is a good approximation Page 574 of certain forms of political behaviour, and thus the rational choice approach is a true theory in a significant number of important cases though it may not explain all cases. The second position is obviously concerned with the question of whether the rationality assumption is realistic or not, that is, the assumption's fit with specific real situations. The first position - ascribing rationality to actors prior to an empirical investigation - is well illustrated by the work of Gary S. Becker. He contrasts sceptics and advocates of the rational choice approach and explains his position as follows: I start with the assumption that behaviour is rational, and ask, 'As I apply this to a particular problem, is there behaviour that I cannot explain with the rationality model?'... Others [who] are more agnostic about the scope of rationality ... will approach a problem by asking, 'Does this look like rational behaviour or is it better interpreted in a different way?' Part of the difference, therefore, is the degree of commitment or confidence one has of finding rational behaviour when investigating a particular set of phenomena [Nota 94]. Becker's statement above well illustrates the point that a pattern of rational behaviour is assumed as a postulate rather than is examined as an empirical question. Becker is also clear about the potential and scope of the economic analysis of human behaviour. He argues that the economic approach provides a comprehensive framework for all human behaviour, but he does not suppose that its application will exhaust useful explanations for all human behaviour. He applies the economic approach because 'all human behaviour can be viewed as involving participants who maximize their utility from a stable set of preferences and accumulate an optimal amount of information and other inputs in a variety of markets [Nota 95]. Simon, by contrast, is more circumspect about using the rationality assumption. He describes it as 'a methodological principle', so that 'if the conditions of the real world approximate sufficiently well the assumption of an ideal type, the derivations from these assumptions will be approximatelycorrect'.96 Differing from that of Becker, this attitude is concerned with the fit between the rationality assumption and real-life situations, as well as with the Page 575 theoretical coherence of the approach based on the assumption. It is consistent with Simon's proposal of bounded rationality as a more realistic assumption than conventional economic rationality. Based on this concept of bounded rationality, there is a third category of new institutionalism, which is too rarely distinguished from rational choice approaches based on economic rationality. Yet the differences between the concepts of economic rationality and bounded rationality are significant. Let me compare and contrast the two different concepts of rationality. Utility maximization according to economic rationality assumes that actors have consistent orderings of preferences, constituting their utility functions. The utility functions may be flexibly defined, but once defined, the actors are assumed to maximize their utility based on it [Nota 97]. Behaviour is chosen from the alternatives and serves as a means to lead to particular specified outcomes. The second premise of the economic approach is thus the consistent link between means and ends. The critical point here is that this model presumes the existence of a 'real situation.' Here I mean a 'real situation' in the context of behaviour. The economic approach presupposes that such a context is specified and constitutes 'one world' in which the behaviour of all individuals is commonly observed and analysed. And thus 'rational' behaviour is objectively defined in relation to the context. The rival concept is bounded or procedural rationality, which tries to explain the process of choosing objectives, selecting means and employing strategies to achieve objectives. The concept of bounded rationality [Nota 98] rests upon more realistic assumptions than that of substantive rationality. The concept focuses on the subjectivity of goal-oriented behaviour. It distinguishes 'between the rationality of perceptions themselves (i.e., whether or not the situation as perceived is the "real" situation) and the rationality of choice, given the perceptions' [Nota 99]. This concept highlights the subjective nature of human self-interested behaviour, that is, 'behaviour that is rational given the perceptual Page 576 and evaluational premises of subjects [Nota 100]. Alternatively, a set of such premises constitutes the environment for human behaviour, and the definition of rationality is inseparable from it. To highlight its difference from substantive rationality, two major points in the bounded rationality approach should be distinguished. The first is the limited capabilities of human beings with respect to information - including misperceptions, misevaluations, limited processing of accumulated information and a limited attention span. Simon writes: The capacity of the human mind for formulating and solving complex problems is very small compared with the size of the problems whose solution is required for objectively rational behavior in the real world - or even for a reasonable approximation to such objective rationality [Nota 101], An emphasis on the limitations of human information capability, however, does not necessarily imply an incomplete and degraded form of rational behaviour. Rather, the bounded rationality approach suggests a notion of rational behaviour that is more reasonable and realistic once the limitations of human capability are taken seriously. With a limited information capability, an individual only 'intends' to be rational, and 'the intended rationality of an actor requires him to construct a simplified model of the real situation in order to deal with it [Nota 102]. One ramification of this approach involves the second point, which distinguishes the concept of bounded rationality from the concept of economic rationality. That is, a simplified model of the real situation is actually nurtured by the environment in which the behaviour takes place. The following passage makes clear the importance of the environment of behaviour in the conceptualization of bounded rationality. It is impossible for the behavior of a single, isolated individual to reach any high degree of rationality... Individual choice takes place in an environment of 'givens' - premises that are accepted by the subject as bases for his choice: and behavior is adaptive only within the limits set by these 'givens'[Nota 103] Subsequently, Simon suggests that organizations often provide an environment that makes their members recognize premises of behaviour and encourages 'rational' behaviour within the context of the organization. Although organizational environment may lead to a more integrated pattern of behaviour, one can easily extend the concern with the environment of rational behaviour to a renewed interest in institutions as a less integrated but more frequently observed environment of behaviour. Page 577 In economics and also in some interdisciplinary fields such as organization theory, the two concepts of rationality are clearly distinguished. The concept of bounded rationality is considered a major challenge to the foundation of conventional economic theory, based on the concept of substantive rationality [Nota 104]. In mainstream political science, however, there is no clear distinction between these concepts [Nota 105]. Some critics of the rational choice approach cite Simon's critical comparison of economic rationality with bounded (or procedural) rationality [Nota 106] and emphasize the limitation of economic rationality. At the same time, however, they often criticize works that are based on the concept of bounded rationality because they regard the works.as attempts to modify conventional rational choice perspectives by postulating incomplete information or subjective utility maximization [Nota 107]. Like their critics, rational choice theorists in political science rarely pay attention to the distinctions between the concepts of bounded rationality and economic rationality that Simon makes [Nota 108]. A distinction between the two concepts, however, has less impact in political science than in economics. The reason for this is quite simple. As Simon emphasizes, many rational choice works in political science, game theoretical models, spatial competition models, and so on, draw heavily on assumptions other than the simple assumption of economic rationality [Nota 109]. Such assumptions include the limited rationality of certain actors - that is, some assumptions of bounded rationality - as well as the shape and nature of the utility function. Differing from the simple and rigorous assumption of economic rationality, these assumptions have to be identified ultimately by empirical research [Nota 110].The Page 578 review of various rational choice approaches in the second section of this article confirms this point. All the literature departs from the simple rationality assumption and incorporates abundant empirical material which constitutes the auxiliary assumptions of the rational choice comparative literature. There are also attempts by rational choice theorists to narrow the distance between inductive and empirical research and rigorous theory of rational action. For example, Laver and Schofield try to bridge the gap between the game theoretic approach to analysing party coalitions and the inductive and empirical approach to examining the real behaviour of party coalitions [Nota 111]. Although the incorporation of yet another rivalry among the advocates of the different concepts of rationality might not seem useful, emphasizing the distinctiveness of the concept of bounded rationality has its own merits. First, more emphasis on the bounded rationality concept will also appeal to many sceptics by showing both the flexibility and realism of an approach focused on rational behaviour. When political scientists replace the concept of economic rationality with one of bounded rationality without changing what they mean, their presentation of analytical results will be in plain language, avoiding strictly defined concepts in economics (equilibrium, Pareto-optimal, and so on). This restriction of the use of economic concepts to formal analysis will not only reduce the doubts of the sceptics, but also serve to maintain the accurate meanings of the concepts themselves. More importantly, the introduction of the concept of bounded rationality opens the possibility of understanding political phenomena and outcomes which the rational choice approach falls short of comprehending [Nota 112]. First, the concept of bounded rationality is useful in explaining seemingly irrational behaviour that reveals a consistent pattern. For example, people's behaviour under a fascist regime and the behaviour of members of terrorist and racist groups are difficult to understand for those outside such regimes or groups, but are organized by consistent rules or patterns. Behaviour in unusual organizational and institutional circumstances is often considered far from rational, but employment of the concept of bounded rationality can help analyse the pattern of that behaviour without marginalizing it as abnormal. Goals, which may seem extravagant for outsiders, can be considered inevitable under a certain perception of the environment. The concept of bounded rationality is especially useful in investigating the perceptional limitation and bias of human beings and connecting them with goal-oriented behaviour. Page 579 The utility of the concept of bounded rationality, however, is not limited to specific fields of comparative studies. Rather it may be more appropriate than the economic rationality concept is in explaining real political behaviour when considering circumstantial conditions that influence individual behaviour. For example, Taylor identifies the conditions under which a strictly defined rational choice theory is more likely to provide strong explanations about real political changes [Nota 113]. According to him, they are; '(1) the options of courses of action available to the agent are limited'; '(2) at least some of the thin incentives facing the agent or the costs and benefits attached to the alternative courses of actions, are to the agent in question well defined'; '(3) ... it matters (or will turn out to matter) a great deal to the individual which action is chosen'; 'and (4) prior to the choice situation there have previously been many similar or analogous occasions [Nota 114]. These conditions actually mean that behaviour is more consistently explained by the strict rationality assumption when individuals are in a situation in which the cost and benefit of their choice is simple and clear, and anyhow they understand the meaning of their choice - that is, in what context their choice will be made and how much gain or damage a specific choice will or is likely to bring. Taylor's discussion implies that the applicability of the rational choice framework to real situations may depend on factors which are not directly concerned with the core of the rational choice framework circumstantial conditions in which the behaviour is taken and the perceptions of the actors about these conditions. If such conditions are not satisfied, individuals are more likely to take different courses of action from the ones based on the strict rationality assumption, and these actions tend to lead to outcomes or consequences that are different from those predicted by the rational Page 580 choice explanation. And, in that case, it is more useful to employ the bounded rationality concept which stresses the limitation of the actor's perception capability and delineates real situations by auxiliary assumptions to explain behaviour. Although there are only a small number of works that use the bounded rationality concept while recognizing its merits as defined above, I can introduce at least two examples in comparative studies. In his comparative study of the development of bureaucratic organizations in France, Japan, the United States and Great Britain, Silberman employs the concept of bounded rationality. He focuses on the 'uncertainty' of situations which political elites faced with the succession of leadership in these countries in the late nineteenth and early twentieth centuries, when bureaucratic organizations were developed [Nota 115]. He explains the different patterns of bureaucratic development across these countries by the greater or lesser uncertainty for political elites who wanted to establish rules of leadership succession and strategically chose specific forms of bureaucracy in order to ensure their possession of power. In the United States and Great Britain in the nineteenth century, individual equality was established in principle, and political leaders established rules for determining possession and succession of power based on social networks or competitive party systems. Because of the low level of uncertainty related to the leadership organizations in these countries, highly professional and politically controlled bureaucracies evolved which were accountable to their constituencies. By contrast, France and Japan experienced revolutionary political changes, and political leaders in these countries faced crises of possession and succession of power in the nineteenth century. Under conditions of great uncertainty, the emerging bureaucratic organization in Japan and France was utilized as a basis of power for political elites, and a classic type of a highly rationalized bureaucracy was developed to decrease the uncertainty of political situations. Silberman's conceptualization of 'uncertainty' does not fit well with the rational choice framework in which uncertainty is regarded as a factor that is a mere constraint on rational behaviour. The problem of uncertainty is solved in the framework of economic rationality by assigning a probability to each course of action and a specific consequence of that action. In his framework, however, the level of uncertainty actually changes the course of action for rational individuals. Silberman convincingly shows, by using historical evidence, that the uncertainty of a political situation itself is a primary factor in determining political elites' strategic responses to an emerging bureaucratic organization. A high or low uncertainty of environment for the power struggle of political elites, together with other institutional arrangements such as social networks or political parties, led to a specific form of bureaucratic organization. Page 581 Only by using the concept of bounded rationality does Silberman construct a framework for comparing rational behaviour. Another example of the use of the concept of bounded rationality is Budge's work on party competition [Nota 116]. Budge's analysis is especially interesting because it offers a spatial theory of party competition distinct from the rational choice approach and is likely to provide a new theory of party competition based on bounded rationality. In his article, the spatial theory of party competition is first called into question by pointing out that politicians can obtain little reliable information about how a party's policy decision influences the next election. To analyse behaviour subject to such uncertainty, Budge employs the bounded rationality concept. Then, based on Schelling [Nota 117], he suggests that, with uncertainty, policy equilibria may emerge from cognitive factors such as ideology rather than from motivational factors such as re-election incentives. The merit of his work is that it goes beyond pointing up the uncertainty to incorporate ideology into the analysis. By doing so he extends his model of electoral competition to a model of government formation and narrows the gap between the spatial theory of electoral competition and the spatial theory of government formation. Budge's work implies that the rational choice theory may not be able to present an adequate and unified model for rational behaviour at different levels. The spatial election model justifies its assumption that politicians seek re-election because votes and office are the most plausible motivations for politicians, while the spatial theory of party coalition regards policy implemen- tation as one of the important goals pursued by parties. The chasm between the two spatial models exists because the goals for electoral competition and for coalition formation, both of which concern party politicians, may not be commensurable. Party politicians want to be re-elected, but, at the same time, once they are re-elected they want to pursue policies that they favour. Thus, Budge raises the possibility that in real situations, the party politicians are likely to rely on ideology that permits them to decide on their behaviour at both the level of electoral competition and party competition in government formation. He confirms his argument with data on party behaviour in twenty democracies. As with Silberman's work, Budge demonstrates that an analysis based on bounded rationality can offer a useful explanation that may not be possible when relying on the rational choice approach. CONCLUSION In this article, I have distinguished three groups of new institutionalists - the socio-historical new institutionalists, the rational choice new institutionalists, Page 582 and the new institutionalists who use a more flexible concept of rationality - in terms of their attitudes to rational behaviour and its relationship to institutions. Then, I showed that neither the socio-historical new institutionalism nor the rational choice approach is superior to the other in terms of institutional analysis. Each approach has different strengths in undertaking comparative studies: the socio-historical approach is suitable for explaining directly the distinctiveness and differences between the cases compared; the rational choice approach employs a different strategy to apply the assumption of rational behaviour and illuminates institutional differences that produce distinct policy and political outcomes. I argue that the most critical dispute between the sociohistorical new institutionalism and the rational choice approach involves epistemological commitments to methodological individualism, not the issue of whether to employ the rationality assumption. In the final section, I introduced a distinction between the concepts of economic rationality and bounded rationality and proposed the utility of the bounded rationality concept in an analysis of real behaviour.

Some of the works, of course, may involve more than one perspective and, thus, it is difficult to classify all the works into the above-mentioned categories.

Nota 33 - página 560 Pederson, 'Nine Questions to a Neo-Institutional Theory', also presents a characterization of common theoretical points of the first group of institutionalists. My presentation here is compatible with, but still distinctive from, each of his points, because here I am primarily concerned with its relationship with the rationality assumption, which Pederson includes, but does not make the focus of his discussion. Nota 34 - página 560 This definition is oversimplified, but, at this point, it is sufficient to show that the criticism on the rationality concept is misdirected.

See A. Tversky and D. Kahneman, 'Rational Choice and the Framing of Decision', in Hogarth and Reder, eds, Rational Choice. Becker turns this qualification into the strength of the rationality assumption by showing that economic behaviours at the market level can be rational even though irrational decisions dominate individual behaviour in that market.

I will show in the last section that this version of organization theory belongs to the third category of new institutionalists if the two different concepts of rationality are clearly distinguished.

Nota 83 - página 570 The recent work by Putnam is also a good example of the works which combine historical observation and empirical data with an analysis of collective action problems by rational individuals. By comparing communities in northern and southern Italy using detailed empirical data over two decades, Putnam's work has discovered the importance of the environment of individual behaviour in determining the consequences of collective action (see R. D. Putnam, Making Democracy Work: Civic Traditions in Modem Italy (Princeton, NJ: Princeton University Press, 1993). Nota 84 - página 570 Steinmo, Taxation and Democracy.

Nota 88 - página 570 Steinmo,Taxation and Democracy, chaps. 4-6. Nota 89 - página 570/571 It is possible to speculate that the selection of the policies to be studied is a result of the differences between the works by Rogowski and Steinmo. In a trade issue, those with vested interests are more attentive to policy problems and sensitive to gains and losses, because trade affects their major economic activities. However, a tax issue influences the members of a society widely but not very explicitly, and thus they are less likely to seek reliable information and are not always as eager to pursue their interests. In other words, if the political actors put a higher priority on tax issues in their political and/or economic activities, they can be expected to seek their interests more rationally. My work on the recent Japanese tax reform explores this possibility by focusing on a bureaucratic organization in which the policy problems and goals are explicitly defined and shared among members (see J. Kato, The Problem of Bureaucratic Rationality (Princeton, NJ: Princeton University Press, 1994). Nota 90 – página 571 Steinmo, Taxation and Democracy, pp. 201-2. Nota 91 –página 572 M.

Nota 94 - página 574 Swedberg, Economics and Sociology (Princeton, NJ: Princeton University Press, 1990), p. 41. Becker may go to an extreme here because, in another instance, he himself attempts to defend the approach instead of regarding its use only as a commitment (G. S. Becker, Economic Approach to Human Behavior (Chicago: University of Chicago Press, 1976)). Nota 95 - página 574 Becker, Economic Approach to Human Behavior, p. 14 (emphasis added). Of course, other rational choice theorists may prefer to defend the rationality assumption for other reasons. For example, G. Tsebelis, Nested Games: Rational Choice in Comparative Politics (Berkeley: University of California Press, 1990), pp. 39-43, defends the rational choice theory as a more coherent theory than alternative approaches because of its theoretical clarity, equilibrium analysis, deductive reasoning, and the interchangeability of individuals in an analysis. Nota 96 - página 574 Simon, Models of Bounded Rationality, Vol. 2, p. 370. Nota 97 - página 575 The minimax rule in a game theoretical situation has the same premise, but applies a different rule of choosing alternative means from a maximization rule and chooses an alternative so as to minimize the worst possible loss. Nota 98 - página 575 Simon uses the terms 'procedural rationality' or 'bounded rationality' to mean the same concept which he presents. Both terms - 'bounded rationality' and 'procedural rationality' - mean basically the same concept, though Simon usually uses the former in more formal and the latter in more descriptive analysis. For a formal presentation of this concept, see Simon, 'Behavioral Model of Rational Choice', and Simon, 'Rational Choice and Structure of Environment'. For an interesting contrast between the rationality concept in game theory and that in learning theory, see H. A. Simon, 'A Comparison of Game Theory and Learning Theory', Psychometrika, 21 (1956), 267-72, reprinted in Simon, Models of Bounded Rationality, and Simon, Models of Man. For further understanding of this concept, see Simon, Models of Bounded Rationality, pp. 203-495; Simon, Models of Man, pp. 196-206 and pp. 241-79. For application to political science, see H. A. Simon, 'Human Nature in Politics', American Political Science Review, 79 (1985), 293-304. Nota 99 - página 575 Simon, 'A Comparison of Game Theory and Learning Theory', p. 271. 575 Nota 100 - página 577 Simon, 'A Comparison of Game Theory and Learning Theory'. The application of bounded rationality is also different from an expected utility theory in economics. The expected utility theory presumes the existence of a 'real situation' and then defines the utility function with probabilities. Nota 101 - página 577 Simon, Models of Man, p. 198. Nota 102 - página 577 Simon, Models of Man, p. 199. Nota 103 - página 577 H. A. Simon, Administrative Behavior, 3rd ed. (New York: The Free Press, 1976), p. 79. Nota 104 - página 577 Simon himself makes this point very clear in his recent writing. See H. A. Simon, 'The State of American Political Science: Professor Low's View of Our Discipline', Political Science and Politics, 36 (1993), 49-50, especially p. 50. Nota 105- página 577 In decision theories and organization theories, the concept of bounded rationality has long attracted the attention of scholars. Allison's work on the Cuban Missile Crisis is a prominent example of such studies (Graham Allison, Essence of Decision (Boston, Mass.: Little, Brown, 1971)). However, the employment of the bounded rationality concept in these fields aims to illuminate the limitations of the perception and information capabilities of human beings without paying much attention to the environment of rational behaviour. This is one of the important reasons why the distinction between the two different concepts of rationality has been neglected in political science. Nota 106- página 577 For example, see Simon, 'Human Nature in Politics'. Nota 107-página 577 Such examples are: North, Institutions, Institutional Change, and Economic Performance; 0. E. Williamson, Markets and Hierarchies: Analysis andAntitrust Implication (New York: The Free Press, 1975); Williamson, Economic Institutions of Capitalism. This misunderstanding may derive from the fact that both North and Williamson utilize the concept of bounded rationality to emphasize the incompleteness of information and information burdens on rational individual.

Simon, 'Rationality as Process and as Product of Thought', American Economic Review, 68 (1978), 1-16, reprinted in Simon, Models of Bounded Rationality; Simon, 'Human Nature in Politics'. Nota 110 - página 577/578 Curiously enough, Becker, as I have shown above, agrees with Simon that the economic approach is supported by auxiliary assumptions. They differ in whether to give up the economic approach when faced with the necessity of assumptions other than economic rationality. Becker maintains the assumption of economic rationality because he believes it serves to bind together various human behaviour within a unified framework. Simon replaces it with the assumption of bounded rationality because he is more concerned with specifying auxiliary assumptions that support his framework for analysing rational behaviour. Nota 111 - página 578 Michael Laver and Norman Schofield, Multiparty Government: The Politics of Coalition in Europe (New York: Oxford University Press, 1990). Nota 112 – página 578/579 A theoretical example of a behaviour that is truly counter to the assumption of economic rationality is a 'commitment' that 'involves choosing an action that yields a lower expected welfare than an alternative available action´(A.K. Sen, ´Rational Fools: A Critique of the Behavioral Foundations of Economic Theory', in Mansbridge, ed., Beyond Self-Interest (Chicago: University of Chicago Press, 1990), pp. 32-3). When a person's consistent ordering of choosing behaviour is not necessarily related to the person's individual welfare, 'the existence of a "variety of motives" makes a difference' (see A. K. Sen, 'Beneconfusion', in J. G. T. Meeks, ed., Thoughtful Economic Man: Essays On Rationality, Moral Rules and Benevolence (Cambridge: Cambridge University Press, 1991), 12-16, at p. 15). In other words, the rational choice framework is silent about the human psychology that shapes the actor's motivation to make choices. A rational choice theorist's quick response to Sen's point about limitations of the economic rationality assumption may be: as long as social scientists are concerned with social outcomes and not with individual psychology, the economic assumption is useful (see W. Riker, 'Political Science and Rational Choice', in Alt and Shepsle, Perspectives on Positive Political Economy, at p. 173). But, some economists are increasingly interested in that field. For example, see R. M. Hogarth and M. W. Reder, eds, Rational Choice: The Contrast Between Economies and Psychology (Chicago: University of Chicago Press, 1987). Nota 113 - página 579 Michael Taylor, 'Structure, Culture, and Action in the Explanation of Social Change', Politics and Society, 17 (1989), 115-57. He defines a strict theory of rational choice as a thin rational choice theory as follows: '(1) rational action is action that is instrumental in achieving or advancing given aims in the light of given belief; (2) the agent is assumed to be egoistic; and (3) the range of incentives assumed to affect the agent is limited.' Nota 114 - página 579 Taylor, 'Structure, Culture, and Action', p. 150.
