Exporting and Offshoring with Monopsonistic Competition
构建了一个异质性企业与垄断竞争劳动力市场的国际贸易模型，发现商品出口通过资源重新配置提高福利，而任务离岸外包可能因增强企业垄断势力导致福利损失。
Abstract We develop a model of international trade with heterogeneous firms and monopsonistically competitive labour markets. We show that due to monopsonistic competition our model makes sharply different predictions about the effects of the export of goods and the offshoring of tasks. Trade in goods is unambiguously welfare increasing as domestic resources are reallocated to large firms with high productivity and firms with low productivities exit the market thereby reducing the monopsony distortion present in autarky. Offshoring, however, gives firms additional scope for exercising monopsony power by reducing their domestic size and therefore can lead to welfare losses.
