Data for: Market size, structure, and access: Trade with capacity constraints

Abstract of associated article: This paper develops a model of international trade where firms are heterogeneous across capacity and productivity. A binding capacity constraint induces firms to raise prices in order to take advantage of access to new markets. This generates markets with a flexible competitive structure giving rise to instances where trade and trade liberalization negatively impact welfare. Its key predictions can be identified by observing the presence of small yet highly productive firms and substitution by firms across markets as accessibility evolves. Using Thai firm-level data I establish the prevalence of these anomalous firms and demonstrate they face capacity constraints.

关联论文摘要：本文构建了一个企业在产能与生产率层面存在异质性的国际贸易模型。当企业面临产能紧约束时，会通过提高定价来把握新市场的准入机遇。这使得市场呈现出弹性竞争格局，进而会出现贸易与贸易自由化对社会福利产生负面影响的情形。本文的核心理论预测可通过两类现象加以识别：一是体量小巧但生产率极高的企业的存在，二是随着市场准入条件变化，企业在不同市场间的替代行为。本文利用泰国企业层面的微观数据，证实了这类异常企业的普遍存在性，并证明它们确实面临产能约束。
