Globalization and Market Structure
回顾全球化中的一些经济谜题，指出完全竞争或垄断竞争模型无法解释，并基于一般均衡中的寡头模型，分析贸易自由化对产业结构、跨境并购浪潮以及技能与非技能工人收入分配的影响。
This paper reviews some puzzling economic aspects of globalization and argues that they cannot be satisfactorily addressed in perfectly or monopolistically competitive models. Drawing on recent work, a model of oligopoly in general equilibrium is sketched. The model ensures theoretical consistency by assuming that firms are large in their own markets but small in the economy as a whole, and ensures tractability by assuming quadratic preferences defined over a continuum of goods. Applications considered include the effects of trade liberalization on industrial structure, on cross-border merger waves, and on the distribution of income between skilled and unskilled workers.
