近日，我院副教授唐立鑫的独立作者论文“Entrepreneur Income Inequality, Aggregate Saving and the Gains from Trade”被国际权威经济学期刊Review of Economic Dynamics接受发表。
Although research has examined the effects of trade on entrepreneur income inequality, the welfare implications of such effects are not well understood. To address this issue, I develop a dynamic model of trade with incomplete markets. In the model, exporting entrepreneurs have both the highest profit and the highest saving rate in the economy. An increase in trade openness increases the share of total profits received by exporters, and thus increases the aggregate supply of capital in the economy. The model reconciles a number of documented stylized facts. Quantitative analysis shows that the novel mechanism in the model amplifies the trade-induced increase in capital stock by 2.1 percentage points, and the trade-induced increase in wage by 0.7 percentage point relative to a comparable benchmark.
