One of the strongest trends in recent macroeconomic modeling of labor market fluctuations is to treat unemployment inflows as acyclical. This trend stems in large part from an influential paper by Shimer on "Reassessing the Ins and Outs of Unemployment," i.e., the extent to which increased...

Many theoretical models of labor market search imply a tight link between worker flows (hires and separations) and job gains and losses at the employer level. Partly motivated by these theories, we exploit establishment-level data from U.S. sources to study the relationship between worker flows...

We develop a life-cycle model of the labor market in which different worker-firm matches have different quality and the assignment of the right workers to the right firms is time consuming because of search and learning frictions. The rate at which workers move between unemployment, employment...

This paper analyzes the effects of fixed-term contracts using a version of the Lucas and Prescott island model with undirected search. A fixed-term contract of length J is modeled as a tax on separations of workers with tenure higher than J . While in principle these policies require a very...

Microeconomic flexibility, by facilitating the process of creative-destruction, is at the core of economic growth in modern market economies. The main reason for why this process is not infinitely fast, is the presence of adjustment costs, some of them technological, other institutional. Chief...

Recent declines in job tenure have coincided with a shift away from traditional defined benefit (DB) pensions, which reward long tenure. Recent 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...

This paper develops a dynamic model of mismatch. Workers and jobs are randomly assigned to labor markets. Each labor market clears at each instant but some labor markets have more workers than jobs, hence unemployment, and some have more jobs than workers, hence vacancies. As workers and jobs...

This paper introduces a notion of fir m size into a search and matching model with endogenous job destruction. The outcome is a rich, yet analytically tractable framework that can be used to analyze a broad set of features of both the cross section and the dynamics of the aggregate labor market....

In this paper I explore optimal employment contract design in a random search framework, where workers search on and off the job for employment opportunities similar to that of Lentz (2010) and Bagger and Lentz (2013). The worker determines the frequency by which employment opportunities arrive...

This paper uses data from the Health and Retirement Study to examine retirement and related labor market outcomes for the Early Boomer cohort, those in their mid-fifties at the onset of the Great Recession. Outcomes are then compared with older cohorts at the same age. The Great Recession...
