Abstract We develop a theory of political transitions inspired in part by the experiences Western Europe and Latin America. Nondemocratic societies are controlled by a rich elite. The initially disenfranchised poor can contest power by threatening social unrest or revolution, and this may force the elite to democratize. Democracy may not consolidate because it is more redistributive than a nondemocratic regime, and this gives the elite an incentive to mount a coup. Because inequality makes democof racy more costly for the elite, democracy and may end up highly unequal societies are less likely to consolidate between regimes or in a nondemocratic repressive regime. An unequal society is likely to experience fiscal volatility, but the relationship between inequality and redistribution is nonmonotonic; societies with intermediate levels of inequality consolidate democracy and redistribute more than oscillating both very equal and very unequal countries. We also show that asset redistribution, such as educational and land reform, may be used to consolidate both democratic and nondemocratic regimes. Keywords: democracy, dictatorship, inequality, political instability, redistribution.

For example, in Britain, following the first tentative reforms of 1832, voting rights were significantly extended in 1867 and in 1884. They were further expanded in 1919, when universal male suffrage was introduced, and in 1928, when all this process of democratization. women were allowed to vote. There were no reversals in Although many less developed countries, most notably those in Latin America, also became democratic during the late 19th and early 20th 1 century, they quickly reverted to nondemocratic regimes. Latin American countries is therefore marred by In Argentina, for example, universal male suffrage soon overthrown by a coup in 1930. coup 1983. The oscillations in became Democracy was why has it has mass democracy been durable in been so hard to consolidate and out But re-instated in 1946, but and many of democracy. effective in 1912. in 1955, re-created again in 1973, subverted again in 1976, Why recent history of it fell was to a finally re-installed in many Northern European countries, this set of political institutions in less and developed countries such as those in Latin America? This paper provides a framework for analyzing this question. in We emphasize that democratic societies the poor impose higher taxes on the rich than in nondemocratic societies. This makes the poor pro-democratic while simultaneously giving the rich an incentive to oppose democracy. political 2 In nondemocratic societies, the poor are excluded from power, but shocks, for example wars or depressions, threat (or at least costly social unrest). 3 The may create a revolutionary rich (elite) will try to prevent revolution before the mass democratization of the 19th century, Britain had elections with a very restricted nondemocratic regimes have often been military dictatorships. We do not distinguish between these different types of non-democratic regimes. We also define any significant move towards mass democracy as "democratization". 2 For example, Rodrik (1999) shows that democracies tend to have higher wages and higher labor share. In the context of Latin America, there are many examples of military coups specifically aimed at reducing redistribution (see Skidmore, 1967, Smith, 1978, Stepan 1978, and Wallerstein, 1980). For example, in Argentina, the labor share, which increased rapidly during the democratic regime of 1946-49, fell during There were similar increases in the following dictatorship (e.g., Di Telia and Dornbusch, 1989, p. 6). inequality in Brazil after 1964 when the left-wing President Goulart was deposed, and in Chile, the coup of 1973 was aimed in part at stopping and reversing the increasingly redistributive policies of Allende. 3 Haggard and Kaufman (1995) document the importance of shocks and crises in regime changes. In Acemoglu and Robinson (1997), we provide evidence on the importance of wars and depressions in triggering social unrest from 19th century Europe. franchise, while in Argentina, by making concessions to the poor, for is guarantee future redistribution.

So inequality for the rich elite. and out of democracy. 4 As a More result, generally, when the stakes, economic gains from controlling political power, are greater, a view that can be traced to James Madison (1788). In consolidated democracies, such as the OECD economies, the threat of coups is not important, so taxes are determined by the usual trade-off for the median voter be- tween transfers and deadweight redistribution. losses. There is little or no variability in the In contrast, in highly unequal economies, fiscal policy cause as a society fluctuates between different regimes, the amount of changes. 5 Even if often limit taxes. 4 more more More of volatile, be- fiscal redistribution an unequal society prevents regime changes, the threat of coups generally, while greater inequality in a consolidated increases redistribution (e.g. Meltzer to be in the is amount and Richards, 1981), an unequal society will democracy is less likely redistributive fully-consolidated democratic regime. 6 may account for why many Latin Amerhad difficulty in consolidating democracy, while the more equal European countries and Costa Rica have had more stable democracies. It is also in line with the correlation between inequality and political instability documented by Muller and Seligson (1987) and Alesina and Perotti (1996). °This accords with some of the patterns observed in the data. For example, Gavin and Perotti (1997) show that fiscal policy in Latin America is much more variable than in Europe. They report that the standard deviation of the growth of transfers in Latin America between 1970 and 1995 was 22.4% as compared to 4.4% for industrialized countries. 6 This may explain the lack of a well-defined monotonic relationship between inequality and redistribution in the data (e.g. Perotti, 1996). Our model is also consistent with the consensus view that "populist" policies are a result of high levels of inequality, and suggests an explanation for why these policies are often reversed radically by regime changes (e.g., Sachs, 1990): populist policies arise as a method of radical redistribution when the poor majority realize that democracy is not consolidated. Countries that consolidate democracy, such as Costa Rica and Colombia, are therefore less likely to follow populist policies. For example, Kaufman and Stallings (1991, p. 27) write "established democracies (Venezuela, The connection between inequality and political transitions ican countries, such as Argentina, Brazil, Peru, and Uruguay, have Our basic analysis suggests that high levels of inequality induce frequent regime When, changes. in addition to this conclusion needs to racy costly for the elite, making concessions, the be modified. Very high elite can use a repression strategy, levels of inequality, may encourage them to use repression to which make democ- prevent democratization. Therefore, low levels of inequality are necessary for a democracy to consolidate, and high inequality to lead to is likely social unrest suppressed some form of political instability (either regime changes or by repression). Since the incentives to engage in or avoid by underlying asset fiscal redistribution, which are generated inequality, are a key factor in shaping regime dynamics, there important role for asset redistribution, e.g. educational and land reforms. is an Educational reforms that increase the earnings capacity of the poor and land reforms that achieve a more egalitarian distribution of assets difficult to reverse, less costly for however, as their anticipation Brazil in 1964, and Chile Although the reasons may make the elite. 7 fiscal redistribution There is by the median a danger in radical reforms, a coup more likely as in Guatemala in 1954, in 1973. for the ferent social groups appears to (1997), consolidate democracy because they are reduce the preferred amount of and make democracy voter, may changes in regimes are numerous, conflict between be important we presented evidence suggesting that in practice.

In Latin America, same factors. many instances of democratization appear to have been driven by the 8 Our paper is related to the analyses of the political economy of redistribution (e.g., Meltzer and Richards, 1981, Persson and Tabellini, 1994, and Alesina and Rodrik, 1994, Benabou, 1999) and to models of Tornell and Velasco, 1992, There is social conflict (e.g., Roemer, 1985, Grossman, 1991, Ades and Verdier, 1995, and Benhabib and Rustichini, 1995). a large political science literature on democratization, starting with the work of our study) were also associated with orthodox macro policies... It was the and Brazil) that followed populist policies." 7 This may help to explain why democracy was consolidated in Costa Rica after 1948 and Venezuela after 1958, two countries that instituted land and educational reforms following democratization. 8 Collier (1998) has recently argued that social pressure from the masses was the driving force behind the most recent democratizations in Peru, Uruguay, and Brazil. Similarly, in Argentina both the 1912 reforms, which institutionalized universal male suffrage, and the withdrawal of the military in 1973, which reinstated Peron, appear to have been a response to increasing social unrest (see Rock, 1987, Ch. 8 and circa p. 188). In Venezuela, the democratizations in 1945 and 1958 both happened in the context of a widespread uprising (see, e.g., Levine, 1989, p. 256, and Kolb, 1974, p. 175). The pattern also appears to be quite similar in Guatemala and El Salvador (see, for example, Paige, 1997). Colombia and Costa Rica in transitional democracies (Peru, Argentina Moore Lipset (1959) and (1966), which emphasizes the structural determinants of racy (such as income level and class composition). strategic interaction economic factors between regimes and More recent work has focused on the and on their opponents, democ- political rather than Rustow, 1970, O'Donnell and Schmitter, 1986, Przeworski, 1991, (e.g., Therborn (1977) and Rueschemeyer, Stephens and Stephens Linz and Stepan, 1996). (1992) share our emphasis on the actions of the disenfranchised poor as the key to under- we standing democratization, and in our previous work, Acemoglu and Robinson (1997), also emphasized democratization as a commitment to future redistribution. The ture on coups is much less how developed and focuses mostly on litera- purely political factors explain the persistence or collapse of democratic politics (for example, Dahl, 1971, and This contrasts with our focus on social conflict and redistribution (though Linz, 1978).

In Section 2, we present our basic model of political development and study the determinants of transitions between regimes. In Section we consider a simple extension of the model to discuss to avoid democratization. redistribution.

The Basic Model There are two groups of agents: the poor and the The rich (the elite). political state be democratic or nondemocratic.

First, the rich may control more votes (Benabou, 1999, Rodriguez, 1998). Second, the poor may view themselves as upwardly mobile and not vote for high redistribution (Wright, 1996, Benabou and Ok, 1998). Third, if redistribution fulfills an insurance function and if insurance is a normal good, increasing inequality may reduce the demand for insurance and hence redistribution (Moene and Wallerstein, 1998). Finally, there may multiple dimensions on which citizens vote, splitting Previous explanations of why high levels of inequality the constituency for redistribution (Roemer, 1998). 15 Repression 3 So far we have assumed not allowed them to use repression Such repression social unrest. some when the society In this section, example, in Indonesia in cases, for we The main of our results. a democracy, but we have in nondemocratic in order to prevent is many observed in is 1965 and in El Salvador in 1932. repression will qualify mount a coup that the rich can show that the will results of our analysis so far are: 1. democracies are more likely to consolidate in more equal societies. 2. frequent regime changes are more likely in In this section, we show possibility of more unequal societies. that in very unequal societies, the elite may have much so to lose from democratization as to prefer a repression strategy to suppress revolution and prevent democratization.

Asset Redistribution 4 We now extend the model of Section 2 to allow redistribution. To simplify the analysis, on the configurations of interest rather we for asset redistribution as well as fiscal ignore the possibility of repression, and focus than giving a complete characterization of possible cases. Let us define 9q to be the initial distribution of assets and use 9 all the for the distribution after redistribution has been undertaken. Unlike fiscal redistribution, if asset be reversed, but it also has inequality permanent costs. is reduced, We it is model the permanent 21 and cannot costs asset redistribution reduces the total stock of assets in the economy. stock, then the post-redistribution stock differentiable decreasing function, is < H'(.) i.e. reduces total resources. Also obviously h 4.1 H(9), where if = H(9 = If h is the 0, so asset redistribution 1. Asset Redistribution under Democracy Recall that 9 L is defined by l (p = L where 8 !p(9 ,q,s) so that without any asset redistribution the L > 9 , and assume economy would oscillate l <p < 7p(6 ,q,s) between regimes. Hence, for democracy to be (semi-) consolidated, inequality needs to be reduced, needs to be raised to 9 20 initial a concave twice continuously is and H"(.) < ) by assuming that L . Also assume that 9 R > 9 where h jj, = R ~p(9 , q). We first i.e. 9 assume Notice that the formulation with a fixed cost of military repression is not essential for this result. if the degree of repression is variable, it will be the societies with greater inequality, where the elite Even have more to lose from democratization, that use more repression. 21 For our general results, asset redistribution does not need to be permanent, it only needs to be harder to reverse than fiscal redistribution. In practice, it may be easier to reverse asset distributions than democracy, which is ultimately an empirical question. 17 that 9 R is Vp ((p h Let , Vp (ip h where 8P {9) W 9 < 9 L , p is is <p D, , h = 9) then the poor if W$(6) = if</>' 9 + 8 P {9) = 9H{9)/\ > 9 L , [(1 is given by - s)Vp {ip h D, 9) + sWp (9)] l ip = 9H(9)/X.

Acemoglu and Robinson In (1997), 19th century Britain and France was in part a result of democratization, and Engerman, Mariscal and Sokoloff (1998) argue the same for Latin America. In Britain and France, these and other policies reduced inequality and there were no significant reversals in the process of democratization. In Costa Rica, the educational and land reforms that reduced both earnings and land inequality after the democratization in 1948 appear to have helped with the consolidation of democracy (see Yashar, 1997, for this argument, and Vilas, 1995, for some numbers). 23 The situation in Venezuela after the return to democracy in 1958, which led to a land reform redistributing 19.3 percent of agricultural land, 24 also provides some support 4.2 We to this view (see Powell, 1971). Anticipated Asset Redistribution and Political Instability have so far illustrated the role of asset redistribution in consolidating Since asset redistribution is permanent and costly to the 23 elite, democracy. the anticipation of such Chalker (1995) writes that "the most remarkable egalitarian measure in Costa Rica occurred in the when the concentration in income distribution was reduced. Interestingly this was an outcome, rather than a cause of, democratic politics." 1960's and 1970's 24 See Table 10.2 in Cardoso and Helwege (1992). 20 may redistribution We l ip > now analyze will ~ip(9o,q,s) so that democracy ) (semi-)consolidated without asset is period of democracy, in the state with first However, we assume that there and the implementation of h <p The poor . then the rich a one period delay between the is h (ip may mount a coup to avoid asset redistribution before it is we assume that during the be no will implemented.

A number by a of coups in Latin America appear to have been motivated prevent radical land reform. desire to For example, in Brazil, a central aim of the coup in 1964 was to prevent the attempt by the left-wing President Goulart to by-pass the veto of the Congress and use other means to push through agrarian reform (see, for example, Skidmore, 1967, and Wallerstein, 1980). Similarly, most scholars argue that the agrarian reform after 1952 in Guatemala was the main motivation 1984, Trudeau, 1993), cially for the coup of 1954 (Handy, and that the increasing radicalization of Allende's on land reform, precipitated the coup of 1973 in Chile. 25 policies, espe- The same is true in Venezuela, where the 1948 land reform law was immediately repealed by the incoming military government (see Dorner, 1992, p. 47, 4.3 The Asset Redistribution in Nondemocratic Regimes rich may also wish to undertake asset redistribution in order to stop a revolution or Therefore, our analysis in this subsection will reveal another strategy democratization. for the elite repression. when We that democracy, faced with the threat a revolution, in addition to democratization and continue to assume if n h > ~p,(9 26 ,q), but suppose that created, will be fully consolidated. away from the poor 2o and Powell, 1971). is not possible, See Valenzuela (1989).

The key equations from Section 2 are modified as follows. 24 The poor will now set a m tax rate T given by ap - 6 A when they are not constrained by the threat of a coup, and the rich will set a tax rate, r nd satisfying , when they When are not constrained by the threat of revolution (and the state is (<p h equation (2) in Section , r S (9) 2, = l^T m - T m h r l In the state, (<p setting r = with the only difference that now, 6P (8) may once ,D), the poor With targeted l , E) the all income r at the rate make transfer that the poor can rich will r nd = = ^-T m — r m hp transfers, however, they now tax at the rate r nd nd 0). , and can do better than and target a x is will also r {@) ar fraction when they have power). to the rich r x (@) were negative, r = would be better).

Therefore, This result also puts one of our basic results from Section 2 into perspective; greater inequality increases political 25 instability because it increases the stakes in the political game, giving greater incentives to each group to fight to regain power (a point also emphasized A less similar argument implies that the critical value for than Jl(6,q) as given by (11) in Section transfers, political regimes are more such as many So, 2). h fi ~jt(9,q), is now lower when the government can power has more economic value, and between oscillations (i.e., direct different This implies that politics will be more unstable in countries, likely. in Africa, , by Madison, 1788). where ethnic or geographic segregation of different groups makes targeted transfers possible. This extension also emphasizes that our model can be applied to political conflict between any two groups, rather than only between the rich and the poor. the two parties can be thought of as rural urban interests in conflict over transfer two ethnic groups, with the one of resources to urban areas, or resources from the other group, vs. For example, in power transferring and the group out of power contesting political power. Conclusions 6 In this paper, we have developed a simple theory of political transitions. Our theory emphasizes the role of the threat of revolution and social unrest in leading to democratization and the desire of the rich elite to limit redistribution in causing switches to nondemocratic regimes. Inequality emerges as a crucial determinant of ity as it political instabil- encourages the rich to contest power in democracies, and also often encourages social unrest in nondemocratic societies. Therefore, inequality is However, in very unequal nondemocratic frequent regime changes. generally conducive to societies, the rich choose a repressive strategy in order to prevent democratization and revolution. cases, is democracy limited, is more and inequality likely to is be consolidated if may In all the level of inequality in the society likely to lead to political instability, either in the form of frequent regime changes or repression of social unrest. Inequality also likely to lead to fiscal volatility, as the redistributive regime changes is with the political system of the society. to more redistribution. regimes, there be used to is Unequal societies switch no redistribution. stabilize Nevertheless, inequality does not necessarily lead between regimes and in nondemocratic Our theory suggests that asset redistributions may both democratic and nondemocratic regimes, but the anticipation of a radical asset redistribution, such as a land reform, consolidated democracy because the elite may mount reforms. 26 may destabilize an otherwise a coup specifically to avoid the References Acemoglu, Daron and James.
