One of the most important long-run trends in the U.S. labor market is polarization, defined as the relative growth of employment in high-skill jobs (such as management and technical positions) and low-skill jobs (such as food-service and janitorial work) amid the concurrent decline in...

This paper examines how job quality varies over the cycle. Empirical evidence from the National Longitudinal Survey of Youth (NLSY) suggests match quality is procyclical. This interpretation is corroborated in a calibrated model with on-the-job search. In the model, more high quality matches are...

This paper studies the extent to which the cyclicality of gross and net occupational mobility shapes that of aggregate unemployment and its duration distribution. Using the SIPP, we document the relation between workers' (gross and net) occupational mobility and unemployment duration over the...

This paper studies the extent to which the cyclicality of gross and net occupational mobility shapes that of aggregate unemployment and its duration distribution. Using the SIPP, we document the relation between workers' (gross and net) occupational mobility and unemployment duration over the...

We build an analytically and computationally tractable stochastic equilibrium model of unemployment in heterogeneous labor markets. Facing search frictions within markets and reallocation frictions between markets, workers endogenously separate from employment and endogenously reallocate between...

This paper expands on the methodology of Groshen and Potter (2003) for studying cyclical and structural changes in the US economy and analyzes the net structural and cyclical employment trends in the US economy during the last 10 trough-to-trough business cycles from 1949 to the present. It...

We propose a model to evaluate the U.K.’s zero-hours contract (ZHC) – a contract that exempts employers from the requirement to provide any minimum working hours, and allows workers to decline any workload. We find quantitatively mixed welfare effects of ZHCs. On one hand they unlock job...

We propose a model to evaluate the U.K.'s zero-hours contract (ZHC) - a contract that exempts employers from the requirement to provide any minimum working hours, and allows employees to decline any workload. We find quantitatively that ZHCs improve welfare by enabling firms with more volatile...

The paper explains how a country can fall into a quot;low-skill, bad-job trap,quot; in which workers acquire insufficient training and firms provide insufficient skilled vacancies. In particular, the paper argues that in countries where a large proportion of the workforce is unskilled, firms...

Following massive take-up rates during the COVID-19 period, short-time work (STW) policies have attracted renewed interest. In this paper, we take stock of this policy instrument and provide a critical review of STW systems in Europe. We focus on the objectives of STW programs and their primary...
