We propose a general theory that explains the extent of the state and accounts for related institutions as byproducts of the state's extractive technology. We posit further that this extractive technology is determined by the transparency of the production technology. This theory is applied to...

We study interventions to restore efficient lending and investment when financial markets fail because of adverse selection. We solve a design problem where the decision to participate in a program offered by the government can be a signal for private information. We charac terize optimal...

We consider a financing game with costly enforcement based on Townsend (1979), but where monitoring is non-contractible and allowed to be stochastic. Debt is the optimal contract. Moreover, the debt contract induces creditor leniency and strategic defaults by the borrower on the equilibrium...

We propose a theory by which geographic variations in the transparency of the production process explain cross-regional differences in the scale of the state, in its hierarchical structure, and in property rights over land. The key linkage between geography and these institutions, we posit, is...

A group of rational individuals with common interest need to select one of two outcomes. The optimal decision depends on whether certain premises or pieces of evidence are established as being true, and each member receives a noisy signal of the truth value of the relevant premises. Should the...

We construct a model of revolution and transition to democracy under an individualistic and a collectivist culture. The main result is that, despite facing potentially larger collective action problems, countries with an individualistic culture are more likely to end up adopting democracy faster...

We estimate the income elasticity of government expenditures using variation in the international oil price as a plausibly exogenous source of within-country variation of countries’ permanent income. Our short run elasticity estimates, between 0.25-0.50, are generally somewhat smaller than the...

We describe a model of fundraising in social groups, where private information about quality of provision is transmitted by social proximity. Individuals engage in voluntary provision of a pure collective good that is consumed by both neighbors and non-neighbors. We show that, unlike in the case...

In their survey of the literature on ethnic fractionalization and economic performance, Alesina and La Ferrara (JEL 2005) identify two main directions for future research. One is to improve the measurement of diversity and the other to treat diversity as an endogenous variable. This paper tries...

We try to demonstrate how economists may engage in research on comparative politics, relating the size and composition of government spending to the political system. A Downsian model of electoral competition and forward-looking voting indicates that majoritarian---as opposed to...
