Benevolent governments lacking commitment ability provide too much insurance, if opportunistic private agents free ride on the government's concern and exert too little effort expecting government assistance. Yet, the costs of implementing the transfer policy work as a commitment device,...

Excess distortions in the welfare state might result from the government lack of ability to commit not to help unlucky agents. Incentive considerations that are crucial in standard insurance in the presence of moral hazard play no role in this case. A benevolent government that sets transfers...

This paper shows that labor market policies and institutions have an impact on the effectiveness of economic reform programs. Countries with relatively 'rigid' labor markets experienced deeper recessions before adjustment and slower recoveries afterwards. Minimum wages and mandatory benefits are...

We present a simple model of a benevolent government that provides insurance to risk averse individuals. As in macroeconomics, commitment to fully contingent rules is better than discretion, but when the government can only commit to simple rules, discretion may be the best available option. The...

We present a new database of social security indicators for 11 Latin-American countries designed to show how much they promise to pay in return to contributions. These are based on micro-simulations according to existing norms. We use response-surface analysis to characterize simulation results....

I analyze political agency models with potentially two equilibria, one in which elections are e¤ective selection mechanisms and only "good" individuals participate in politics and another one in which elections are not e¤ective and "bad" individuals participate in politics. These equilibria...

The contribution of government transfer programs to inequality is often assessed by analyzing to what extent the benefits paid go to lower income families. Several analysts have found that some key government transfers actually go mostly to middle and high income families and thus contribute to...

This paper shows that labor market policies and institutions have an impact on the effectiveness of economic reform programs. The analysis compares annual growth rates across 119 countries, using data from 449 adjustment credits and loans given by the World Bank between 1980 and 1996. The...
