We study unemployment insurance for workers who sequentially sample job opportunities. We focus on the optimal timing of benefits and the desirability of allowing borrowing and saving. When workers have constant absolute risk aversion, a simple policy is optimal: a constant benefit during...

We characterize the design of an optimal trade agreement when governments are privately informed about the value of tariff revenue. We show that the problem of designing an optimal trade agreement in this setting can be represented as an optimal delegation problem when a money burning instrument...

We propose a continuous time model to investigate the impact of inflation credibility on sovereign debt dynamics. At every point in time, an impatient government decides fiscal surplus and inflation, without commitment. Inflation is costly, but reduces the real value of outstanding nominal debt....

Different beliefs about the fairness of social competition and what determines income inequality influence the redistributive policy chosen in a society. But the composition of income in equilibrium depends on tax policies. We show how the interaction between social beliefs and welfare policies...
