Abstract
The current DMP approach to labor markets presumes job destruction shocks are small. We relax that assumption and also allow un lled jobs, like unemployment, to evolve as a state variable. Calibrating an otherwise standard DMP framework, we identify a remarkable, (almost) perfect, fit of the empirical facts as reported in Shimer (2005, 2012). The results, how- ever, are also consistent with the insights of Davis and Haltiwanger (1992): that unemployment volatility is driven by large but infrequent job separation shocks. The approach not only provides an important synthesis of two litera- tures which, in other contexts, have appeared contradictory, it also identfies a more traditional view of the timing and progression of recessions
