Detecting Learning by Exporting
指出传统计量方法因假设生产率外生而可能遗漏出口学习效应，通过允许生产率内生调整，利用斯洛文尼亚微观数据发现了企业进入出口市场后生产率显著提升的证据。
Learning by exporting refers to the mechanism whereby a firm's performance improves after entering export markets. This mechanism is often mentioned in policy documents, but many econometric studies have not found corroborating evidence. I show that the econometric methods rely on an assumption that productivity evolves exogenously. I show how to accommodate endogenous productivity processes, such as learning by exporting. I discuss the bias introduced by ignoring such a process, and show that adjusting for it can lead to different conclusions. Using micro data from Slovenia, I find evidence of substantial productivity gains from entering export markets.
