Task Trade Between Similar Countries
研究了要素禀赋和技术相似但规模不同的国家之间如何进行任务贸易，发现离岸成本最高的任务可能不参与贸易，而成本较高的任务会在工资和产出较高的国家完成。
We propose a theory of task trade between countries that have similar relative factor endowments and technological capabilities, but may differ in size. Firms produce differentiated goods by performing a continuum of tasks, each of which generates local spillovers. Tasks can be performed at home or abroad, but offshoring entails costs that vary by task. In equilibrium, the tasks with the highest offshoring costs may not be traded. Among the remainder, those with the relatively higher offshoring costs are performed in the country that has the higher wage and the higher aggregate output. We discuss the relationship between equilibrium wages, equilibrium outputs, and relative country size.
