We revisit an old question: does industry labor reallocation affect the business cycle? Our empirical methodology exploits variation in a local labor market’s exposure to industry reallocation on the basis of the area’s initial industry composition and national industry employment trends for identification. Applied to confidential employment data over 1980–2014, we find sharp evidence of reallocation contributing to higher local area unemployment if it occurs during a national recession but little difference in outcomes during an expansion. A multiarea, multisector search-and-matching model with imperfect mobility across industries and downward nominal wage rigidity can reproduce these cross-sectional patterns.

The flow opportunity cost of moving from unemployment to employment consists of forgone public benefits and the forgone consumption value of nonworking time. We construct a time series of the opportunity cost of employment using detailed microdata and administrative or national accounts data to estimate benefits levels, eligibility, take-up, consumption by labor force status, hours, taxes, and preference parameters. The opportunity cost is procyclical and volatile over the business cycle. The estimated cyclicality implies far less unemployment volatility in leading models of the labor market than that observed in the data, irrespective of the level of the opportunity cost.
