Wage and sensitivity to trade conditions

A heterogeneous-firm trade model with endogenous markups predicts that wage affects an exporter's sensitivity to trade conditions. When trade costs increase, the extensive margin of trade is more sensitive for low-wage exporters than high-wage exporters, but the intensive margin is less sensitive. This model explains the large impact of Chinese exports on US manufacturing. We present empirical evidence in support of this model by testing its implications for the sensitivity of trade volume and exchange rate pass-through.
