In an extended version of the model we show that the previous prediction also holds in the presence of additional sources of labor-force heterogeneity such as higher wage rigidity of high skilled workers. Empirically, we document that the negative hiring-expected return relation is between 1.7 and 3.2 times larger in indust...
