Abstract

We construct a multiple-shock, discrete-time 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. In addition to the standard labor productivity shock, we introduce shocks to matching efficiency and job separation. We estimate the multiple-shock model and then simulate its properties. Although it generates significantly more volatility while preserving the Beveridge curve relationship, the multiple-shock model generates counterfactual implications for the cyclicality of job separations. Using a business cycle accounting approach, next we show that the model requires significantly procyclical and volatile matching efficiency and counterfactually procyclical job separations to render the observed data without error. We conjecture that the basic Mortensen–Pissarides model lacks mechanisms to generate sufficiently strong labor market reallocation over the business cycle, and suggest nontrivial labor force participation and job-to-job transitions as promising avenues of research.
