Journal of Economic Perspectives—Volume 16, Number 3—Summer 2002—Pages 31– 44 Intergenerational Inequality: A Sociological Perspective Robert Erikson and John H. Goldthorpe W hen economists are concerned with the inheritance of inequality, they typically focus on the intergenerational transmission of income or wealth. In contrast, sociologists are more likely to analyze intergenerational mobility between (and immobility in) different class positions. One immediate consequence is that while economists usually work with intergenerational correlations of income or wealth treated as continuous variables, sociologists more often work with intergenerational patterns of association between class positions that are treated categorically. The standard data array takes the form of a contingency table in which class “origin” is crossed with class “destination.” The former variable is usually indexed by class of father or other household “head” at the time of a child’s—that is, the survey respondent’s—adolescence; the latter variable, by the child’s (respondent’s) present class or class at time of inquiry. The reliability with which father’s class can be established in survey interviews has been subject to a good deal of investigation with reasonably satisfactory results (Hope, Schwartz and Graham, 1986; Breen and Jonsson, 1997) and is in any event more accessible than father’s income. The child’s, or respondent’s, class at time of inquiry is not of course xed, and signi cant worklife or intragenerational mobility does occur. But it is known that the frequency of such mobility falls off rather sharply after around age 35, and intergenerational mobility tables are therefore sometimes restricted to respondents over this age. The difference in approach between sociologists and economists is not, however, absolute. Sociologists have studied intergenerational social mobility on the basis of correlations of parents’ and children’s “socioeconomic status” scores (Blau and Duncan, 1967; Featherman and Hauser, 1978). Following the pioneering work y Robert Erikson is Professor of Sociology, Swedish Institute for Social Research, Stockholm, Sweden. John H. Goldthorpe is Ofcial Fellow, Nufeld College, Oxford University, Oxford, United Kingdom. 32 Journal of Economic Perspectives of Atkinson, Maynard and Trinder (1983), several other economists have of late adopted contingency table methods in analyzing intergenerational income mobility, using income quantile groups as their categories (for example, Dearden, Machin and Reed, 1997; Hertz, 2001). Björklund and Jäntti (2000, p. 24) have in fact recently called for further work of this kind, applying “more exible measures of association” in place of correlation (or regression) coef cients, on the following grounds: “There are, a priori, no good reasons to believe that the association between fathers’ and sons’ incomes is the same throughout, over e.g. the income range of fathers.” Atkinson, Maynard and Trinder (1983, p. 180) also make the important point that a contingency table approach is able to bring out important asymmetries in mobility patterns—for instance, long-range upward movements being offset by more gradual “trickling down processes”—that correlation or regression coef cients cannot capture. Operationalizing Class If the inheritance of inequality is treated in terms of class mobility, an obviously crucial question that arises is that of how the concept of class is to be understood and made operational. As an initial point here, we would distinguish the concept of class from that of “socioeconomic status,” which has been widely used in American social science—and sometimes as the basis for constructing occupational categories rather than an interval-level scale. We would regard class positions as being determined by employment relations (for more detailed statements, see Erikson and Goldthorpe, 1992, chapter 2; Goldthorpe, 2000, chapter 10). Thus, a primary division is that among employers, self-employed workers and employees. However, employees, who make up the large majority of the workforces of modern societies, require further differentiation, which can, we believe, be provided in a theoretically consistent way by reference to the mode of regulation of their employment. The problems employers face, ultimately on account of the essential incompleteness of employment contracts and more immediately in regard to work monitoring and human asset speci city, lead to contracts of signi cantly differing form being offered to employees who are engaged to carry out different kinds of work. These range from the “labor contract,” a simple recurrent spot contract for the purchase of a quantity of labor on the basis of piece or time rates, via various modi ed or mixed forms, through to the “service relationship,” an exchange of a longer term and more diffuse kind in which compensation for service to the employing organization involves important prospective elements, such as salary increments, expectations of continuity of employment or at least of employability and promotion prospects and career opportunities. A class schema, using employment status and occupation as indicators of employment relations, can then be drawn up on the general lines shown in Table 1. Versions of this schema have in fact been widely applied in studies of intergenerational mobility, and in other sociological research, since the 1980s, and Robert Erikson and John H. Goldthorpe 33 Table 1 The Class Schema Class I. II. IIIa. IIIb. IVa. IVb. IVc. V. VI. VIIa. VIIb. Occupational Grouping/Employment Status Regulation of Employment Professionals, administrators and managers, higher-grade Professionals, administrators and managers, lower-grade; technicians, higher-grade Routine nonmanual employees, higher grade Routine nonmanual employees, lower-grade Small employers Self-employed workers (nonprofessional) Farmers Technicians, lower grade; supervisors of manual workers Skilled manual workers Nonskilled manual workers (other than in agriculture) Agricultural workers service relationship service relationship (modi ed) mixed labor contract (modi ed) — — — mixed labor contract (modi ed) labor contract labor contract the schema is now attracting increasing interest from national and international statistical agencies as a basis for of cial social classi cations.1 It is important to note that since the schema aims to capture qualitative differences in employment relations, the classes distinguished are not consistently ordered according to some inherent hierarchical principle, such as, say, the “general desirability” of the positions they comprise. Their members may be relatively advantaged or disadvantaged in different ways. Thus, routine nonmanual employees in Class IIIa may have lower average incomes than do small shopkeepers in Class IVb or technicians and foremen in Class V, but more stable levels of income than the former and better chances of promotion than the latter. However, so far as overall economic status is concerned, individuals in Classes I and II, representing the “service class” or “salariat,” could in fact be regarded as generally advantaged over individuals in Classes IIIb, VI and VIIa and VIIb, representing the working class, in at least three ways that follow directly from the mode of regulation of their employment and that, together, we would see as being of at least comparable importance to current income alone. Members of the salariat are advantaged over members of the working class in that they experience i) greater long-term security of income through being less likely to lose their jobs and to become unemployed; ii) less short-term (week-to-week or month-to-month) uctu1 The schema has become known as either the EGP (Erikson, Goldthorpe and Portocarero) or CASMIN (Comparative Analysis of Social Mobility in Industrial Nations) schema, the latter being the name of a project directed from the University of Mannheim by Walter Müller and John Goldthorpe from 1984 –1990. Since 2000, a new instantiation of the schema has in fact been adopted as the of cial British social classi cation under the (somewhat unfortunate) name of the National Statistics Socio-Economic Classi cation, and active consideration is presently been given to the use of the schema as the basis for a general European Union social classi cation. One valuable spin-off of such of cial interest is that resources have been made available to test the validity of the schema: that is, the extent to which, as implemented via information on employment status and occupation, it does in fact capture the kinds of differences in employment relations that it is conceptually supposed to capture. The results of such tests have been generally encouraging (for Britain, see Rose and O’Reilly, 1997, 1998). 34 Journal of Economic Perspectives ation of income through being less dependent on piece rates, shift premiums, overtime payments and less exposed to loss of pay on account of absence or illness; and iii) better prospects of steadily increasing income over the life course—into their 50s rather than their 30s—through having employment contracts that are conducive to an upward-sloping age-earnings pro le (Lazear, 1995) with in turn better prospects for the accumulation of wealth.2 One last point that needs to be made here is the following. Sociologists are interested in class and class mobility not only as dependent, but also as independent, or explanatory, variables: ones that can be set in competition with other variables, including income and income mobility, in their capacity to account for variation in a wide range of life chances (say, health) and life choices (like political partisanship). Empirically, class effects on such outcomes tend to persist even when income is controlled. It is possible that class, as operationalized on the lines indicated above, serves as a good proxy for permanent income. In addition, though, we believe that its explanatory power stems from the fact that it is able to capture important aspects of the social relations of economic life. Analyzing Class Mobility To measure the association between class origins and class destinations, sociologists most often use the odds ratio. For the simplest possible mobility table, that with only two classes of origin and destination, say class 1 and class 2, the one calculable odds ratio is given by odds ratio 5 f11 /f12 , f21 /f22 where f 1 1 is the frequency in cell (1,1), that referring to immobility within class 1, f 1 2 is the frequency in cell (1,2), that referring to mobility from class 1 to class 2, and so on. So in this case, the odds ratio gives the chances for an individual originating in class 1 being found in class 1 rather than in class 2, relative to the same chances for an individual originating in class 2. An odds ratio with the value of 1 thus indicates the absence of association between origins and destinations (or their statistical independence). The odds ratio is attractive because it is a “margin insensitive” measure of association (Bishop, Fienberg and Holland, 1975), which means that it is invariant to the multiplication of any row or column of a contingency table by a (nonzero) constant. In an intergenerational mobility table, what might be called the gross association between origin class and destination class will be conditioned by differences in the overall distributions of these variables—the marginal distributions of 2 Moreover, even insofar as the classes cannot be perfectly ordered, we do not believe that this makes the question of mobility between them irrelevant to issues of equality of opportunity and social justice. For discussion of this point, see Marshall, Swift and Roberts (1997, appendix E). Intergenerational Inequality: A Sociological Perspective 35 the table—that re ect changes in the proportions of individuals found in different class positions across generations. For example, in the course of economic development, fewer children than fathers will become farmers, but more will become managerial and professional employees. Thus, some intergenerational mobility will of necessity occur in the form of out ow from the class of farmers and in ow to that of managers and professionals. For many purposes, this mobility will be of interest in itself.3 But odds ratios provide a measure of the association of origins and destinations that is net of the effects of such class structural change and that can therefore remain constant even when such change is extensive or, conversely, that can alter even when such change is absent.4 In mobility tables with more than two categories, more than one odds ratio will be calculable—in fact, one for every possible pair of origin categories considered in relation to every pair of destination categories. Thus, the number of odds ratios implicit in a square mobility table with k categories will be given by [(k 2 2 k) 2 ]/4, although it can be shown that a “basic set” of (k 2 1) 2 odds ratios can be speci ed that will determine the remainder (Goodman, 1979). The full set of odds ratios implicit in a mobility table is taken to constitute the “endogenous mobility regime” or, alternatively, the underlying “pattern of social uidity.” For testing substantive hypotheses about endogenous mobility regimes, loglinear or logmultiplicative models, the parameters of which are odds ratios or functions of odds ratios, are chie y used (Hout, 1983; Erikson and Goldthorpe, 1992). Such models can serve to represent particular hypotheses—for example, that odds ratios are unchanged in a society over a period of time or are the same across a number of societies, or that they change or differ in particular ways—and the t of selected models to the actual data of mobility tables can then be assessed via standard statistical procedures. When the main empirical features of endogenous mobility regimes have been established and attention shifts to the actual processes of mobility that underlie these regimes, loglinear models for the grouped data of mobility tables can be rewritten as multinomial logistic regression models for individual-level data (Logan, 1983; Breen, 1994). Class position is the dependent variable, and class origin gures as one of a set of independent variables also including, for example, measures of individual IQ, effort, educational attainment and other relevant variables. It thus becomes possible to examine how far the inclusion of such variables in the analysis leads to the dependence of class of destination on class of origin 3 Sociologists do in fact analyze out ow and in ow rates in simple percentage terms: that is, by considering the percentage distribution of all individuals of a given class of origin across all destination classes or, conversely, the distribution of all individuals in a given class of destination across all origin classes. But it is important to distinguish these “absolute” mobility rates from the “relative” rates captured by odds ratios. 4 The motivation here could be thought of as somewhat similar to that behind the Galton measure of intergenerational correlation in income, which normalizes for changes in the mean and standard deviation of the income distribution over time. When intergenerational income mobility is studied via a contingency table approach, using income quantile groups as the categories, the problem of controlling differing marginal distributions obviously does not arise. 36 Journal of Economic Perspectives being reduced or, in other words, how far mobility regimes may be thought of as meritocratic. Results Measuring intergenerational economic mobility through correlation or regression coef cients, as economists most typically do, leads to results that can be very concisely expressed. Sociologists’ results relating to the mobility regimes that operate within class structures are more complex, since it is supposed that the association between class origins and destinations may vary in strength across the component cells of the mobility table—that is, from one intergenerational transition to another. This supposition turns out in fact to be fully warranted, so what is lost in parsimony is gained in realism. With, then, some degree of simpli cation, the main ndings from recent sociological research could be summarized as follows. First, in all modern societies, signi cant associations between class of origin and class of destination prevail. For men, at least, there is a broad similarity in endogenous mobility regimes across societies.5 This represents an interesting parallel with the cross-national similarities in estimates of the extent of intergenerational income mobility noted by Björklund and Jännti (2000, p. 4, n. 4). Some nationally speci c variation in mobility regimes is also apparent; but, within this variation, differences in the overall level of the origin-destination association, as opposed to its pattern, is only one—in fact rather minor— element. Consequently, no nation or nations stand out as showing decisively more social uidity or openness than the rest. The idea of American exceptionalism in this regard is a myth (Erikson and Goldthorpe, 1985, 1992, chapter 9). Among economically advanced societies, Sweden appears as the most open, but has still to be seen as marking one end of a quite limited range of differentiation rather than being in any sense sui generis. Second, the main features of the cross-national commonality in mobility regimes are the following. There is a general propensity for intergenerational class immobility through the operation of what might be called class-speci c inheritance effects. These effects are relatively strong within Classes I and II, the salariat, and Classes IVa and IVb, small employers and self-employed workers, and strongest of all within Class IVc, that of farmers. In addition, there is a general propensity for mobility to be reduced by “hierarchy” effects deriving from the overall advantages and disadvantages associated with different class positions (as discussed above). These effects especially operate between Classes I and II, on the one hand, and Classes VIIa and VIIb, the nonskilled division of the working class, on the other. To 5 Although it has not so far been demonstrated, we would think it highly probable that such a result will hold for women, also. The mobility regimes for men and women within particular nations have repeatedly been shown to differ little—apart from the fact that odds ratios for women overall tend to be slightly lower than for men. Robert Erikson and John H. Goldthorpe 37 give some indication of the importance of class inheritance and hierarchy effects together, the odds of a man originating in the salariat being himself found in the salariat rather than in the nonskilled working class, relative to the same odds for a man originating in the nonskilled working class, would, across modern societies, be of the order of 15:1.6 Third, within particular societies, mobility regimes show a high degree of constancy over time, and in some cases, such as Great Britain (Goldthorpe, Payne and Llewellyn, 1987; Goldthorpe and Mills, forthcoming) or Japan (Ishida, 1995), for periods extending back to the rst half of the twentieth century. Loglinear models that postulate no change in odds ratios reproduce the empirical data remarkably well, usually misclassifying less than 5 percent of all individuals in the mobility tables analyzed. In societies where trends in the overall level of uidity can be discerned, these are more often in the direction of increasing uidity— odds ratios moving generally closer to 1—than of decreasing uidity. But such trends, as well as being slight, would seem more often to be episodic as, say, in the United States (Erikson and Goldthorpe, 1992, chapter 9) or Sweden ( Jonsson, forthcoming) than sustained, as in France (Vallet, forthcoming). The idea of a worldwide and secular movement toward greater societal openness has been mooted (Ganzeboom, Luijkx and Treiman, 1989), but this is scarcely borne out by the evidence so far accumulated. An alternative hypothesis is that the level of social uidity will inversely relate to the degree of economic inequality between classes (Erikson and Goldthorpe, 1992, chapter 11; Goldthorpe, 2000, chapter 11). This hypothesis does in fact nd support from one of the very few studies of trends in intergenerational income mobility so far carried out (Blanden et al., 2001). Fourth, educational attainment is a major—probably the major—mediating factor in class mobility (Ishida, Müller and Ridge, 1995; Marshall, Swift and Roberts, 1997), although this is more apparent when education is measured by highest level of quali cation achieved (academic or vocational) rather than by number of years of education completed, as is the usual American practice.7 In the British case, the tradition of birth cohort studies provides data sets that allow for the effects of IQ and of effort (in the sense at least of academic motivation as measured on standard psychological scales) to be reliably compared with that of education. The latter proves to be clearly stronger, and further, the effects of IQ and effort appear to operate largely via educational attainment, at all events so far as the mediation of early life mobility (up to around age 30) is concerned (Breen and Goldthorpe, 1999). Fifth, modern societies are not meritocracies in the sense that, once educational quali cations and other “merit” variables are controlled, class of destination 6 Sector effects, operating between the classes of farmers and agricultural workers and the rest, reduce propensities for mobility still more strongly than do hierarchy effects and were indeed a major feature of the mobility regimes of many modern societies even up to the middle decades of the twentieth century, although they are by now of much reduced importance overall. 7 The standardized measure that is chie y used here is the CASMIN educational classi cation (König, Lüttinger and Müller, 1988; Brauns and Steinmann, 1999). 38 Journal of Economic Perspectives is no longer dependent on class of origin. To the contrary, a signi cant and often substantial dependence remains (Marshall, Swift and Roberts, 1997; Breen and Goldthorpe, 1999, 2001). In some cases, for example, Sweden, the persisting effect of class origins has been shown to extend to income, also (Erikson and Jonsson, 1998). Thus, as Breen and Goldthorpe have put it (1999, p. 21): “Children of disadvantaged class origins have to display far more merit [as indicated by educational attainment or by IQ and effort] than do children of more advantaged origins in order to attain similar class positions.” Sixth, the mediating role of education varies signi cantly in its importance from one type of intergenerational transition to another. Thus, educational quali cations have been shown to be of no importance at all in mediating intergenerational immobility (for which there is a high propensity) within any of the subdivisions of Class IV: that is, among small employers, self-employed workers or farmers (Ishida, Müller and Ridge, 1995). What appears crucial here is the direct intergenerational transmission of “going concerns” or of economic capital in other forms—a factor that Bowles and Gintis in this issue also nd important for the intergenerational income correlation. Further, several studies now in progress suggest that educational quali cations are of greater importance in “long-range” upward mobility—as, say, from working-class origins into the salariat—than they are in intergenerational immobility within the salariat (for example, Guzzo, 2002). Here in particular, the advantages of a disaggregated, contingency table approach can be seen. Effects that bear on mobility from speci c origins to speci c destinations can show up in a way that would not be possible if the same regression rules were simply assumed to apply across the board. Problems and Prospects There are at least two outstanding problems, in part related, that we would recognize, along with Bowles and Gintis. The rst is what Bowles and Gintis call the “black box” problem. More than half of their preferred coef cient for the intergenerational transmission of income remains unaccounted for even when all conventional explanatory variables are included in the analysis. We in fact believe that the situation is less clear—and possibly worse—than Bowles and Gintis suppose, since we would question whether their efforts to disentangle the relative importance of heredity and environment and also of direct transfers of assets warrant such precise estimates as they venture. For example, a key assumption underlying their estimates is that the difference in the intergenerational correlations of earnings or income between identical and fraternal twins will be indicative of the importance of genetic effects, since twins of both kinds share the same environmental conditions. Bowles and Gintis do acknowledge that environments may in fact be somewhat more similar for identical than for fraternal twins; but, we would argue, there is Intergenerational Inequality: A Sociological Perspective 39 more to it than that. The often symbiotic relation between identical twins will lead them to strive to keep together, while fraternal twins may actively seek to distinguish themselves from each other. Thus, identical twins may follow the same education, not because their genetic make-up leads them both to choose it, but simply because they do not want to be separated; and the same wish may likewise in uence their family life, place of residence and other factors. 8 If one identical twin gets a job offer, he or she may not take it in order to avoid separation, geographic and/or social, from the other twin. Now the more equal conditions, including in income, that are thus likely to result among identical twins are certainly linked to the fact that they have the same genes. But how can the effect in question be generalized to the population at large?9 However, we would not wish to claim that sociologists are any better placed than economists as regards to the black box problem—that is, as it arises in their understanding of the association between class of origin and class of destination. Indeed, in one respect, the problem appears even more embarrassing for sociologists. Of late, a number of studies have indicated that the part that is played in mediating intergenerational class mobility by educational attainment— our most important conventional explanatory variable—is if anything, declining (for Sweden, see Jonsson, 1992; for Britain, Breen and Goldthorpe, 2001; and Goldthorpe and Mills, forthcoming; for France, Vallet, forthcoming; and for Ireland, Whelan and Layte, 2002).1 0 We are, then, led strongly to agree with Bowles and Gintis that if the black box problem is to be overcome, we will need to examine the possible importance in the inheritance of inequality of a wider range of individual attributes than has so far been considered and, in particular, to be less exclusively concerned with cognitive abilities and with skills, at least as usually understood. We nd much of interest in their suggestions regarding “group membership” effects on economic success and what they elsewhere elaborate as the effects of “incentive enhancing preferences” (Bowles and Gintis, 2001). However, we would also want to take further than Bowles and Gintis a more direct, demand-side approach: that is, asking just what are the attributes of potential employees that employers are looking for and how these desiderata might be changing. In modern economies, there would appear to be, at virtually all levels of the 8 Ashenfelter and Krueger (1994, p. 1159), on whose work Bowles and Gintis chie y rely, do in fact note that identical twins far more often studied together and were also somewhat less often married than fraternal twins. 9 It could further be argued that models such as that used by Bowles and Gintis, in which the effects of heredity and environment are treated as simply additive, are misspeci ed. Evidence is now available (Maccoby, 2000) of interaction effects between hereditary factors and parental childbearing regimes, analogous to those that have for long been demonstrated between genes and environment in the case of various plants, fruit ies and so on. 10 When such results are reported, economists usually react with some surprise or even skepticism on the grounds that earnings returns to education are tending to increase. However, apart from the fact that there is no necessary inconsistency here, for at least some of the countries referred to in the text, the evidence of such increasing returns is not all that compelling. For example, for France, see Baudelot and Glaude (1989); and for Britain, see Chevalier and Walker (2001). 40 Journal of Economic Perspectives class structure, an increasing range of what have been referred to as “peopleprocessing” or, somewhat more cynically, “high-touch” occupations— obvious growth areas being in the leisure, entertainment and hospitality industries, in public relations and the media and in the personalized selling of high-value goods and services. In occupations of this kind, employers may well view cognitive abilities (above some threshold level) and conventional skills as being of less relevance than such attributes as physical appearance, dress sense, accent, self-presentation, lifestyle and savoir faire, along with related “social” or “interpersonal” skills.1 1 For Britain at least, there is some amount of supporting evidence for this speculation from preliminary results from both the content analysis of job advertisements and organizational case studies ( Jackson, 2001; Jackson, Goldthorpe and Mills, 2002; Warhurst and Nickson, 2001). Insofar as such a shift in the pattern of employers’ requirements is in train, an important implication follows. Increasing economic value now attaches to individual attributes of a kind less likely to be achieved through the educational system than ascribed through processes of socialization within generally more advantaged families and communities. In turn, a possible explanation is indicated for both the (apparently widening) gap that arises if we seek to account for the patterning of mobility regimes solely in terms of education and for the fact that education plays a greater part in accounting for upward mobility into more advantaged classes than for intergenerational immobility within these classes.12 Men and women with advantaged class backgrounds acquire, more or less as a matter of course, attributes that help them maintain their position even if their educational attainments are only modest. The second problem that we share with Bowles and Gintis is raised by the rather limited success of public policy aimed at reducing intergenerational inequality and, more speci cally, that of explaining why, even if education plays a lesser role in mediating such inequality than is often supposed, the massive expansion and often radical reform of educational institutions in modern societies has not had a more evident egalitarian outcome. In addressing this problem, we would start from two further sets of empirical results and a conceptual distinction. The rst set of results are those that show that in most societies, class differentials in educational attainment have in fact proved highly resistant to change, even across decades of educational expansion and reform, if these differentials are understood and modeled in terms of the relative odds of children of different class origins making or not making the successive “transitions” by which educational careers are de ned (Blossfeld and Shavit, 1993; Mare, 1980, 1981; Breen and Jonsson, 2000). 11 On this issue, we would add that the repeated references of Bowles and Gintes to “good looks” as genetically transmitted seems to miss the point that “good looks” are, at least in some large part, a social construct, modeled on the example of superior classes or status groups. 12 Other alternative or complementary explanations for this development could of course be proposed: for example, that, as a consequence of the expansion of educational provision and of the growing numbers of individuals who have quali cations of some kind at all levels, the value of education in both signalling by potential employees and in screening by employers is reduced. Robert Erikson and John H. Goldthorpe 41 The conceptual distinction, due to Boudon (1974), is between the “primary” and the “secondary” effects that are at work in this regard. Primary effects are those, whether genetic or cultural, that create class differentials in “demonstrated ability” early in children’s educational careers and in this way condition the options subsequently open to them. Secondary effects are those that later operate through the choices that children, together perhaps with their parents, actually make among the options they have available. The second set of empirical results then serves to show that secondary effects do in fact play a signi cant role in the persistence of class differentials in educational attainment—and in turn represent an obvious focus for policy interventions. These results, from research undertaken within a variety of national educational systems (for full references, see Goldthorpe, 1996), reveal that even when level of demonstrated ability is held constant, children of more advantaged class origins take more ambitious educational options— for instance, stay on rather than leave or choose academic rather than vocational courses—than do children of less advantaged origins. For example, in Sweden in the early 1990s, among children with average grades in primary school, about twice as many from Class I backgrounds as from Class VI and VII backgrounds entered academic tracks in secondary school (Erikson and Jonsson, 1996, p. 77). We are therefore entirely sympathetic to the argument put forward by Bowles and Gintis that the intergenerational persistence of differences in educational attainment results, at least in some important part, from actions taken by parents and offspring under the in uence of a range of subjective dispositions or traits, such as attitudes to risk, orientations to the future and sense of personal ef cacy, that themselves tend to be intergenerationally transmitted. From such a position, a number of sociologists have in fact developed models of educational choice (in some cases to a formal level) and of mobility strategies, in which ideas of risk aversion, the discounting of future rewards and belief in returns to effort and probabilities of success all gure (Erikson and Jonsson, 1996; Goldthorpe, 1996; Breen and Goldthorpe, 1997; Breen, 1999, 2001; Goldthorpe, 2000, chapter 11; Jonsson and Erikson, 2000).13 However, our class structural approach allows us, we believe, to give a rather more detailed and differentiated account than Bowles and Gintis offer in this issue of the social grounding of these dispositions that help preserve inequality across generations. Bowles and Gintis observe that “less well-off people may be more likely to be risk averse, to discount the future and have a low sense of ef cacy” (p. 18) than the better-off. However, children from less advantaged origins may have good 13 The model advanced by Breen and Goldthorpe (1997) has been subjected to various attempts at empirical testing, the most sophisticated of which, setting hypotheses derived from this model against ones derived from the “linear social distance” approach of Akerlof (1997), is by Davies, Heinesen and Holm (forthcoming). The development of this model by Breen (2001) is also of interest in suggesting a behavioral basis for the models of educational transitions proposed by Mare (1980, 1981), in response to the critique of Cameron and Heckman (1998). 42 Journal of Economic Perspectives reasons to avoid high-risk alternatives, even if risk aversion is equally distributed across classes ( Jonsson and Erikson, 2000 p. 364). We would emphasize in this respect not only differences in current levels of income but, further, the differences in economic security, stability and prospects that we previously identi ed as the main sources of class advantage and disadvantage. It is notable, for example, that children of Class IIIa (routine nonmanual) families are regularly found to have levels of educational attainment more similar to those of Class I and II families than to those of Class VI (skilled working class) families, even though in average income, they are much closer to the latter. In addition, we would see the speci c educational and occupational goals that young people pursue as being likewise best understood in relation to their class origins, following the “structural” theory of aspirations initially set out by Keller and Zavalloni (1964) and developed by Boudon (1974). From this standpoint, levels of aspiration are to be assessed not in absolute terms but relative to the positions of those holding them. Instead of the emphasis being on class differences in aspirations, it comes rather to be placed on the shared priority within all classes that children should achieve educational levels and class positions not less desirable than those of their parents or, in other words, should avoid downward mobility.14 However, it may then be the case with children of less advantaged class backgrounds that the safest strategy to this end—for example, opting for a vocational rather than an academic course that carries higher risks of failure—is not best suited to achieving upward mobility. In sum, intergenerational inequality has important self-maintaining properties. It creates conditions under which individuals in less advantaged positions choose and act in ways that can in themselves be understood as adaptively quite rational (rather than, say, being the expression of “dysfunctional” subcultures) yet which, in aggregate, serve to perpetuate the status quo. Educational expansion and reform alone should not therefore be expected to serve as very effective instruments of public policy aimed at creating greater equality of opportunity in the sense of “a more level playing eld.” Complementary efforts to reduce inequalities of condition, and especially class inequalities in economic security, stability and prospects, will also be required. y We are indebted to Tony Atkinson, Anders Björklund, Richard Breen, Adam Swift and the editors for very helpful comments on an earlier draft of this paper. 14 One could alternatively talk, as in Breen and Goldthorpe (1997), of equal relative risk aversion across classes, and there is an obvious af nity with the “prospect theory” of Kahneman and Tversky (1979), according to which the slope of utility curves is greater in the domain of losses than in the domain of gains.
