Standard search models are inconsistent with the amount of frictional wage dis- persion found in U.S. data. We resolve this apparent puzzle by modeling skill development (learning by doing on the job, skill loss during unemployment) and duration dependence in unemployment benefits in a random on...

We develop a dynamic general equilibrium model where workers can engage in search while on the job. We show that on-the-job search is a key component in explaining labor market dynamics in models of equilibrium unemployment. The model predicts fluctuations of unemployment, vacancies, and labor...

In this paper we challenge the traditional labour market view, which argues that unemployment is determined in the long-term by its equilibrium rate, which in turn is affected by permanent shocks of some exogenous variables. In our empirical approach we decompose the dynamics of employment and...

The aim of this paper is to analyze and estimate salient characteristics of unemployment dynamics. Movements in unemployment are viewed as "chain reactions" of responses to labour market shocks, working their way through systems of interacting lagged adjustment processes. In the context of...

We show how on-the-job search and the propagation of shocks to the economy are intricately linked. Rising search by employed workers in a boom amplifies the incentives of firms to post vacancies. In turn, more vacancies induce more on-the-job search. By keeping job creation costs low for firms,...

A number of authors have recently emphasized that the conventional model of unemployment dynamics due to Mortensen and Pissarides has difficulty accounting for the relatively volatile behavior of labor market activity over the business cycle. We address this issue by modifying the MP framework...

Job search models offer two complementary predictions about the effects of unemployment benefits on job search outcomes among unemployed workers. By raising workers' reservation wages, unemployment benefits should contribute to both prolonged spell duration and improved post-unemployment job...

Whereas the standard modern theories of unemployment were developed in the context of a single sector labour market, this paper presents a survey of how these theories can be integrated into a dual labour market setting. This approach dichotomises the labour market into two sectors, a primary...

This work refers to analyses of matching processes on occupational labour markets in Germany. Up to now, all studies in this field are based on the crucial assumption of separate occupational labour markets. I outlined some theoretical considerations that occupational markets are probably not...

This paper makes use of data from the German socio-economic panel to gain new insights into the determinants of unemployment duration in Germany. Due to substantial differences with respect to labour market outcomes we follow a stratified approach with respect to gender and ethnicity. To analyze...
