In the past decades several features of US unemployment dynamics have been investigated empirically. The original focus of research was on the duration of unemployment. In later studies the cyclicality of incidence and duration, compositional effects and duration dependence of the exit rate out...

In this Paper we simultaneously analyse transitions from unemployment to employment and to non-participation. We estimate a dependent competing risks model with non-parametric specifications of the destination-specific duration dependence and unobserved heterogeneity terms, allowing for mutual...

We combine micro and macro unemployment duration data to study the effects of the business cycle on the outflow from unemployment. We allow the cycle to affect individual exit probabilities of unemployed workers as well as the composition of the total inflow into unemployment. We estimate the...

In a large class of hazard models with proportional unobserved heterogeneity, the distribution of the heterogeneity among survivors converges to a gamma distribution. This convergence is often rapid. We derive this result as a general result for exponential mixtures and explore its implications...

Instrumental variable estimation requires untestable exclusion restrictions. With policy effects on individual outcomes, there is typically a time interval between the moment the agent realizes that he may be exposed to the policy and the actual exposure or the announcement of the actual...

This Paper surveys the existing empirical research that uses search theory to analyse empirically labour supply questions in a structural framework, using data on individual labour market transitions and durations, wages, and individual characteristics. The starting points of the literature are...

A major issue in the analysis of unemployment durations concerns distinguishing genuine duration dependence of the exit rate out of unemployment from unobserved heterogeneity. The authors present a method for the nonparametric estimation of both phenomena, designed to be applicable to...

Generally, it is acknowledged that changing the job-offer arrival rate has two opposite effects on unemployment duration. For a basic job search model, sufficient conditions on the wage-offer distribution have been derived, ensuring that one of the effects dominates. However, these are not...

Generally, structural job search models are taken to be stationary. In this paper, models are examined in which every exogenous variable can cause nonstationarity, for instance, because its value is dependent on unemployment duration. A general differential equation that describes the evolution...

Unemployment insurance systems include monitoring of unemployed workers and punitive sanctions if job search requirements are violated. We analyze the effect of sanctions on the ensuing job quality, notably on wage rates and hours worked, and we examine how often a sanction leads to a lower...
