This paper constructs a multiple-shock version of the Mortensen-Pissarides labor market search model to investigate the basic model’s well-known tendency to under predict the volatility of key labor market variables. Data on U.S. job finding and job separation probabilities are used to help...

This paper studies amplification of productivity shocks in labor markets through on-the-job-search. There is incomplete information about the quality of the employee-firm match which provides persistence in employment relationships and the rationale for on-the-job search. Amplification arises...

We show that the inability of a standardly-calibrated stochastic labor search-and-matching model to account for the observed volatility of unemployment and vacancies extends beyond U.S. data to a set of OECD countries -- the volatility puzzle is ubiquitous. We also argue that using cross-country...

This paper evaluates the ability of autoregressive models, professional forecasters, and models that incorporate unemployment flows to forecast the unemployment rate. We pay particular attention to flows-based approaches–the more reduced-form approach of Barnichon and Nekarda (2012) and the...

Okun’s law is a statistical relationship between unemployment and GDP that is widely used as a rule of thumb for assessing the unemployment rate—why it might be at a certain level or where it might be headed, for example. Unfortunately, the Okun’s law relationship is not stable over time,...

We construct a multiple-shock version of the Mortensen-Pissarides labor market search model to investigate the basic model’s well-known tendency to underpredict the volatility of key labor market variables. Data on U.S. job-finding and job separation probabilities are used to help estimate the...

We review the positive and normative effects of a minimum wage in various versions of a search-theoretic model of the labor market.

The past recession has hit the labor market especially hard, and economists are wondering whether some fundamentals of the market have changed because of that blow. Many are suggesting that the natural rate of long-term unemployment—the level of unemployment an economy can’t go below—has...

This paper addresses the question whether search frictions can help us explain some of the movements in the labor wedge. We present a model with labor market frictions -- in the form of search and matching -- that nests the prototype RBC model. Search and matching frictions in our model helps us...
