Abstract
We study the determinants of firm-level heterogeneity in a model where innovation choices uponentry affect the variance of productivity draws. In equilibrium, productivity is Pareto distributed witha shape parameter that depends on industry-level characteristics. We show that export opportunities,by increasing the pay-offs in the tail, induce firms to invest in bigger projects with more dispersedoutcomes. When more productive firms pay higher wages, trade amplifies wage dispersion by makingfirms more unequal. These results are consistent with how firm size, innovation and wageheterogeneity vary in a panel of US industries and states.| File | Dimensione del file | Formato | |
