Interindustry mobility and the cyclical upgrading of labor

We investigate whether a market-clearing model is consistent with industry employment and wage patterns related to the cyclical upgrading of labor. We demonstrate that Roy's (1951) market-clearing model of self-selection woul d account for cyclical upgrading if industries were characterized by positi ve selection. Wage comparisons of industry movers and stayers in panel data do reveal widespread positive selection. Also consistent with the Roy mode l, composition-corrected industry wages are more cyclical in high-wage cycl ical industries. The Roy model does fail to explain predictable patterns in the wage changes of industry movers, so we consider several market-clearin g and queuing extensions.
