Description
Summary:This paper uses readily accessible aggregate time series to measure the probability that an employed worker becomes unemployed and the probability that an unemployed worker finds a job, the ins and outs of unemployment. Since 1948, the job finding probability has accounted for three-quarters of the fluctuations in the unemployment rate in the United States and the employment exit probability for one-quarter. Fluctuations in the employment exit probability are quantitatively irrelevant during the last two decades. Using the underlying microeconomic data, the paper shows that these results are not due to compositional changes in the pool of searching workers, nor are they due to movements of workers in and out of the labor force. These results contradict the conventional wisdom that has guided the development of macroeconomic models of the labor market since 1990. ► The job finding rate is strongly procyclical. ► The employment exit probability is weakly countercyclical. ► This holds in models with and without a participation margin. ► This holds after accounting for worker heterogeneity.
