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...

Why do workers change occupations? This paper investigates occupational mobility and its determinants following a large unexpected shock (communism's collapse in 1989.) Our calculations show that from 1989 to 1995 between 35 and 50 percent of Estonian workers changed occupations (classified at...

The transition from centrally planned to market economy involves a process of massive occupational change that has been largely neglected in the literature. This paper investigates this process using data from the 1995 Estonian Labour Force Survey. We find that between 35 and 50 percent of wage...

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 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...

The NZ labour market is among the most flexible in the OECD, and outcomes for its young people have been among the best. However, labour-market opportunities are heavily determined by initial education, where New Zealand’s system is also successful and innovative in many ways. Average PISA...

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...
