This paper evaluates two theories of unemployment: the natural rate theory (whereby unemployment is depicted as fluctuating around a reasonably stable natural rate) and the chain reaction theory (which views movements in unemployment as the outcome of the interplay between labour market shocks...

This Paper investigates the effectiveness of benefit sanctions in reducing unemployment duration. Data from the Swiss labour market allow making a distinction between the effect of a warning that a person is not complying with eligibility requirements and the effect of the actual enforcement of...

This Paper analyses 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...

With the emergence of the Great Recession unemployment insurance (UI) is once again at the heart of the policy debate. In this paper, we review the recent theoretical and empirical evidence on the labor market effects of UI design. We also discuss policy issues related to UI design, including...

This paper provides a simple model which explains the choice between permanent and temporary jobs. This model, which incorporates important features of actual employment protection legislations neglected by the economic literature so far, reproduces the main stylized facts about entries into...

This Paper estimates the structural parameters of a job search model with hyperbolic discounting and endogenous search effort. It estimates quantitatively the degree of hyperbolic discounting, and assesses its implications for the impact of various policy interventions aimed at reducing...
