The paper emphasizes the role of institutions and incentives in the presence of externalities. An economy with multiple public decision makers is likely to experience “overspending,” “undertaxing,” “overborrowing,” and “overinflation” unless effective institutions exist for...

The purpose of this paper is to analyze the argument that debt relief would increase the incentive of a debtor country to make an adjustment effort (to invest) and that for this reason creditors may benefit by granting relief. It is shown that there are actually opposing incentive effects of...

In addition to transferring about 16 percent of GDP from exporters to importers, Uzbekistan’s quasi-fiscal multiple exchange rate regime generates identifiable welfare losses of 2-8 percent of GDP on import markets and up to 15 percent on export markets. These excess burdens have increased...

Many arguments that have been advanced in favor of maintaining capital controls within the EC have not paid sufficient attention to the welfare consequences of this type of market intervention. Our paper provides a simple, optimizing framework in which the welfare consequences of capital...

The paper proposes a new welfare-based measure to evaluate the distributive effects of public programs. The proposed measure differs from traditional approaches in two important ways: first, it is based on life-cycle considerations, since most public expenditure programs have an intertemporal...

This paper develops and calibrates a simple general equilibrium model with two types of labor and capital for the French economy. The simulation results indicate that targeted reductions in employer social security taxes have six times as large an effect on employment as untargeted reductions...
