Abstract
AbstractWe describe a model of trade with skills‐based product differentiation and non‐proportional trade costs that predicts a positive correlation between firms' export intensity, the price of their exports and the wages they pay to their workers. In equilibrium, firms that employ workers with comparatively scarcer skills export a larger proportion of their output, pay higher wages and charge higher prices. In line with empirical evidence, the model predicts that trade liberalization can cause the distribution of earnings to become more polarized, with patterns that reflect the heterogeneous effects of trade liberalization on firms' export performance.
