Abstract
This paper studies unemployed workers’ decisions to change occupations, and their
impact on fluctuations in aggregate unemployment and its underlying duration distribution. We
develop an analytically and computationally tractable stochastic equilibrium model with
heterogenous labor markets. In this model three different types of unemployment arise:
search, rest and reallocation unemployment. We document new evidence on unemployed
workers’ gross occupational mobility and use it to calibrate the model. We show that rest
unemployment is the main driver of unemployment fluctuations over the business cycle and
causes cyclical unemployment to be highly volatile. The resulting unemployment duration
distribution generated by the model responds realistically to the business cycle, creating
substantial longer-term unemployment in downturns. Finally, rest unemployment also makes
our model simultaneously consistent with procyclical occupational mobility of the unemployed,
countercyclical job separations into unemployment and a negatively-sloped Beveridge curve.
