本文探讨了沉没成本与学习在解释出口持续性中的作用。多项研究将这种持续性归因于沉没的市场进入成本。本文表明，类似的出口模式也是一致的学习机制，并发现了强有力的经验支持这种机制的背景下，哥伦比亚工厂级的数据。其次，本文实证区分两个竞争的理论，并发现，一旦学习控制，沉没成本在产生出口持续性的作用是最多的百分之四十，目前在文献中估计。最后，在差异化产品行业，出口持续性主要是由于学习，而在非差异化产品行业，这种持续性主要是由于沉没成本机制。
This paper explores the role of sunk costs versus learning in explaining persistence in exporting. Multiple studies attributed such persistence to sunk market-entry costs. This paper shows that similar patterns of exporting are also consistent with a learning mechanism and finds a strong empirical support for such a mechanism in the context of Colombian plant-level data. Second, the paper empirically discriminates between the two competing theories, and finds that once learning is controlled for, the role of sunk costs in generating export persistence is at most forty percent of what is currently estimated in the literature. Finally, while in differentiated-products industries export persistence arises primarily due to learning, in the homogeneous-products industries such persistence arises primarily due to the sunk-cost mechanism.
