Democratization or Repression?* Daron Acemoglu^ James A. Robinson* Abstract Regimes controlled by a rich elite often collapse and make way for democracy amidst Such regime changes are often followed by redistribution to the widespread social unrest. poor at the expense of the former elite. We argue that the reason to resort to full-scale democratization, despite its why the elite may have may be apparent costs to themselves, that lesser concessions would be viewed as a sign a weakness and spur further unrest and more radical demands. The elite may therefore be forced to choose between repression and the most generous concession, a transition to full democracy.

One is the reaction the creation of the Kcrcnsky Russia in 1917. Dynamic models of the conflict between the elite and the disenfranchised poor arc analyzed in Accmoglu and Robinson (1997, 1999), where we also give a detailed discussion of the economics and political science literatures related to our approach to democratization. Here, to save space we do not give a literature review and refer the reader to our other papers. The Model II.

We now Game analyze the Perfect Bayesian Equilibria of this game. 4 In order to focus on the cases of interest, we start by making a number of parameter restrictions. First, we impose Assumption 1: A p (r p > Q > A p (r m ) which ensures that redistribution in a poor from a successful revolution. the median voter We also full democracy But the limited is greater than the payoff to the redistribution that will ensue from the middle-class gives the poor less when than a successful revolution. assume Assumption 4 is ), 2: mF > -A r (r m ), game, where an informed player moves before an uninformed player, the concept of may not be sufficient to rule out some unreasonable outcomes, and some equilibrium refinements need be used to rule this out (sec, for example, Cho and Kreps, 1987). Nevertheless, in our simple environment, all Perfect Bayesian Equilibria satisfy the relevant refinements. In this type of Perfect Bayesian Equilibria which implies that repression worthwhile to undertake when the median voter for the flexible type sufficiently costly that is simply to prevent the limited redistribution that it is it not will follow from the middle-class. is Finally, Assumption 3: ^'f/ which ensures that if > A p (r m ), both the weak and the played flexible types A= the poor would prefer to attempt a revolution following A= To c. c all the time, then see why, recall that a A p (r m concession of limited franchise extension gives the poor an additional return of Whereas the poor obtain is unsuccessful. probability that If tt from a successful revolution and both the weak and A= c A — flexible types play comes from a weak tj'pe is $ F T lose if ). a revolution attempt then the c all the time, Assumption 3 therefore ensures . that with such a posterior, the poor prefer to attempt a revolution.

More formally, in this complete information game, the strategy of the poor should be an action conditioned on the type of the rich and their action.
