The competition effects of the Single Market in Europe
研究欧洲单一市场计划如何通过降低贸易壁垒促进竞争，并利用计量经济学和可计算一般均衡方法分析其对贸易模式、竞争行为及福利的影响，发现小国获益更大但面临更多结构调整。
Summary European Single Market How the programme has fostered competitionThe reduction in trade barriers in Europe through the Single Market Programme (SMP) was intended to increase competition in European markets, and hence welfare and efficiency. The paper examines how the SMP has affected trade patterns and what can be learnt from this regarding the impact on competitive behaviour. Combining an econometric and computable general equilibrium methodology, it is argued that (1) the SMP has indeed had a strong impact on competitive behaviour; (2) the extent of the impact depends both on changes in the intensity of competition as well as on changes in the nature of competitive interaction; (3) while all economies experience potentially large welfare gains from the SMP, it is the smaller economies that experience the larger gains, but this in turn suggests that they experience a greater degree of restructuring.—Chris Allen, Michael Gasiorek and Alasdair Smith
