This paper shows that labor market search frictions do not explain fluctuations in the labor wedge per se. However, the introduction of extensive and intensive margin clarifies that measuring the MRS in terms of total hours artificially introduces procyclicality in the MRS. When the MRS is...

This paper assesses whether labor market frictions, in the form of searching and matching, can help explain movements in the labor wedge - the gap between the marginal rate of substitution (MRS) and the marginal productivity of labor in a perfectly competitive business cycle model. Results...

This paper proposes an empirical method for estimating a long-run trend for the unemployment rate that is grounded in the modern theory of unemployment. I write down an unobserved-components model and identify the cyclical and trend components of the underlying unemployment flows, which in turn...

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...

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...

We present a model with search frictions and heterogeneous agents that allows us to decompose the overall increase in US wage inequality in the last 30 years into its within- and between-firm and skill components. We calibrate the model to evaluate how much of the overall rise in wage inequality...

Over the last decade, 11 states have restricted employers' access to the credit reports of job applicants. We document a significant decline in county-level vacancies after these laws were enacted: Job postings fall by 5.5 percent in affected occupations relative to exempt occupations in the...

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...

We show that the inability of a standardly calibrated labor search-and-matching model to account for labor market volatility extends beyond the U.S. to a set of OECD countries. That is, the volatility puzzle is ubiquitous. We argue cross-country data is helpful in scrutinizing between potential...
