Existing unemployment insurance systems in many OECD countries involve a ceiling on insurable earnings. The result is lower replacement rate for employees with relatively high earnings. This paper examines whether replacement rates should decrease as the level of earnings rises. The framework is...

This paper analyzes the design of optimal unemployment insurance in a search equilibrium framework where search effort among the unemployed is not perfectly observable. We examine to what extent the optimal policy involves monitoring of search effort and benefit sanctions if observed search is...

This paper examines the incentive effects caused by the interactions between unemployment insurance (UI) and sickness insurance (SI), two important components of Sweden's social insurance system. There are two main topics of interest: how the sickness report rate and the length of the subsequent...

Should unemployment compensation be paid indefinitely at a fixed rate or should it decline (or increase) over a worker's unemployment spell? We examine these issues using an equilibrium model of search unemployment. The model features worker-firm bargaining over wages, free entry of new jobs,...

The costs of searching for a job vacancy are typically associated with friction that deters or delays employment of potentially productive individuals. We demonstrate that in a labor market with moral hazard where effort is noncontractible, job search costs play a positive role, whose effect may...

The existing literature assumes that unemployment insurance (UI) affects the labor market through the job finding rate of eligible workers. I argue that this focus is too narrow. I show evidence for UI effects through three other margins: (i) search externalities; (ii) takeup of other welfare...

We present a sharp test for the efficiency of job separations. First, we document a dramatic increase in the separation rate - 11.2ppt (28%) over five years - in response to a quasi-experimental extension of UI benefit duration for older workers. Second, after the abolition of the policy, the...
