This paper studies the optimal unemployment insurance for older workers in a repeated principal–agent model, where the search intensity of risk-averse workers (the agents) is not observed by the risk-neutral insurance agency (the principal). When unemployment benefits are the only available...

At the end of working life, as well as reducing unemployment benefits, the unemployment-insurance agency could apply pension tax instead of wage tax. First, the pension tax provides greater incentives as the value of re-employment is tax-free. Second, the short job duration before retirement...

This paper shows how to solve dynamic agency models by extending recursive Lagrangean techniques à la Marcet and Marimon (2011) to problems with hidden actions. The method has many advantages with respect to promised utilities approach (Abreu, Pearce and Stacchetti (1990)): it is a significant...

This paper studies the role of job search assistance programs in optimal welfare-to-work programs. The analysis is based on a framework, that allows for endogenous choice of benefit types and levels, wage taxes or subsidies, and activation measures such as monitoring and job search assistance...

Monitoring the job-search activities of unemployed workers is a common government intervention. Typically, a caseworker reviews the unemployed worker's employment contacts at some frequency, and applies sanctions if certain requirements are not met. I model monitoring in the optimal unemployment...

This paper shows that optimal unemployment insurance contracts are age-dependent. Older workers have only a few years left on the labor market prior to retirement. This short horizon implies a more decreasing replacement ratio. However, there is a sufficiently short distance to retirement for...

How does renegotiation affect contracts between a principal and an agent subject to persistent private information and moral hazard? This paper introduces a concept of renegotiation-proofness, which adapts to stochastic games the concepts of weak renegotiation-proofness and internal consistency...

This paper studies the effect of habit formation on optimal capital taxes in a dynamic Mirrleesian model. We make three distinct contributions. First, we decompose intertemporal wedges (implicit capital taxes) for general time-nonseparable preferences into a wealth effect, a complementarity...

We ask whether offering a menu of unemployment insurance contracts is welfare improving in a heterogeneous population. We adopt a repeated moral-hazard framework as in Shavell/Weiss (1979) supplemented by unobserved heterogeneity about agents’ job opportunities. Our main theoretical...
