This paper develops a model of equilibrium unemployment with (unobservable) endogenous on-the-job search and (partly unobservable) endogenous search behavior by firms. The model allows to analyze crowding-out of unemployed job seekers by endogenous on-the job search of employees, and the...

We survey the microfoundations, empirical evidence and estimation issues underlying the aggregate matching function. Several microeconomic matching mechanisms have been suggested in the literature with some successes but none is generally accepted as superior to all others. Instead, an aggregate...

This paper is about the labour market consequences of creative destruction with on-the-job search. We consider a matching model in an economy with embodied technological progress and show that its dynamics are profoundly affected by allowing on-the-job search. We obtain that the elasticity of...

We use a novel approach to studying the heterogeneity in the job finding rates of the nonemployed by classifying the nonemployed by labor force status (LFS) histories, instead of using only one-month LFS. Job finding rates differ substantially across LFS histories: they are 25-30% among those...

This paper deals with empirical matching functions. The paper is innovative in several ways. First, unlike in most of the existing literature, matching functions are estimated not only on aggregate, but also on disaggregate levels which is unusual due to the scarcity of appropriate data....

The rate of job-to-job transitions is twice as large today as the rate at which workers move from employment to unemployment. I demonstrate that, under plausible specifications, the basic job-ladder model --- the workhorse model of the literature on on-the-job search --- has no chance of...

We estimate Frisch elasticity in a labor market with high job turnover. In a context where only around 18% of the employed labor force has formal and stable jobs, we perform a fixed effects estimation as proposed by MaCurdy (1981) with a Heckman correction for selection into unemployment. We...

Atypical employment contracts are either considered as traps that hinder permanent employment in the primary segment of the labour market or as stepping-stones leading to stable employment. Whereas the former interpretation appears to apply to Germany, our analysis of on-call contracts in the...

En este documento estimamos la elasticidad de oferta laboral de Frisch en un mercado laboral con significativa movilidad laboral. Lo hacemos usando el estimador de efectos fijos de MaCurdy(1981) con corrección por sesgo de selección a-la-Heckman. La pendiente de oferta laboral queda...
