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 analyse labor market dynamics with an agent based model, which replicates a set of stylized facts in the labor market as well as aggregate regularities. We are able to reproduce the Beveridge curve, job creation and destruction flows, a persistent unemployment level, and wages stickiness. On...

Standard search and matching models of equilibrium unemployment, once properly calibrated, can generate only a small amount of frictional wage dispersion, i.e., wage differentials among ex-ante similar workers induced purely by search frictions. We derive this result for a specific measure of...

In this Technical Appendix to Hornstein, Krusell, and Violante (2006) (HKV, 2006, hereafter) we provide a detailed characterization of the search model with (1) wage shocks during employment and (2) on-the-job search outlined in Sections 6 and 7 of that paper, and we derive all of the results...

Recent declines in job tenure have coincided with a shift away from traditional defined benefit (DB) pensions, which reward long tenure. New evidence also points to an increase in job-to-job movements by workers, and we document gains in relative wages of job-to-job movers over a similar period....

Traditional models of the labor market assume fixed firing costs. This paper explores the implications of variable firing costs, building this new assumption into a matching model with endogenous job destruction. The available evidence on the outcomes of cases brought to labor courts suggests...

This paper incorporates a risk-neutral principal-agent model with contractual constraints into a random search model to study the interaction between contracting and search in partial and general equilibrium. I introduce heterogeneity in principals' and agents' production technologies in terms...

This paper examines a labor law reform implemented in Portugal in 2009 which restricted the use of fixed-term contracts to reduce labor market segmentation. The reform targeted establishments created by large firms above a specific size threshold, covering about 15% of total employment. Drawing...

This paper is concerned with the business cycle dynamics in search-and-matching models of the labor market when agents are ex post heterogeneous. We focus on wealth heterogeneity that comes as a result of imperfect opportunities to insure against idiosyncratic risk. We show that this...

Ljungqvist and Sargent (2017) (LS) show that unemployment fluctuations can be understood in terms of a quantity they call the "fundamental surplus." However, their analysis ignores risk premia, a force that Hall (2017) shows is important in understanding unemployment fluctuations. We show how...
