项目摘要

In this research project, I investigated some aspects of the process of policy adjustments performed by the trading countries which aim to form free trade areas and customs union. I introduced imperfect competitive markets in the analyses. The framework of the analyses is basically general equilibrium.First, in a two-country, two-good, arbitrary many factor of production trading model in which one market is international oligopoly, I analyzed the effects of a VERs and quotas on the welfare of the importing country and compared the welfare levels with that under free trade.Secondly I examined the equivalence of tariffs and quotas imposed on oligopolistic intermediate input markets. We focus on a Cournot-Nash equilibrium and show that the outcome depends on the values of the structural parameters of the economy, the price elasticity of demand for the final good and the elasticity of substitution between the intermediate inputs. This analysis could be straightforwardly extended to a tree country model of customs union in which a country importing two intermediate goods forms customs union with one of the trading countries.I next studied the effects of a change in the level of quantity restriction on the behavior of the domestic firm and on the welfare of the importing country. It is shown that the results obtained by predecessors based on linear demand, constant elasticity demand, strategic substitutes and so forth all emerge as special cases.I am now studying a following problem : Which partner is more preferable for a country to form a customs union with, a country with imperfectly competitive markets or a country with perfectly competitive markets?

在这个研究项目中，我调查了贸易国家为建立自由贸易区和关税同盟而进行的政策调整过程的某些方面。我在分析中引入了不完全竞争市场。分析的框架基本上是一般均衡。首先，在一个市场是国际寡头垄断的两国、两种商品、任意多种生产要素贸易模型中，分析了VER和配额对进口国福利的影响，并将其福利水平与自由贸易下的福利水平进行了比较。其次，我考察了对寡头垄断中间投入征收关税和配额的等价性。市场。我们关注古诺-纳什均衡，并表明结果取决于经济结构参数的值、最终商品的需求价格弹性以及中间投入之间的替代弹性。这种分析可以直接扩展到关税同盟的树国模型，其中进口两种中间产品的国家与其中一个贸易国形成关税同盟。接下来，我研究了数量限制水平的变化对国内企业行为和进口国福利的影响。结果表明，前人基于线性需求、恒定弹性需求、战略替代等得出的结果都是特例。我现在正在研究这样一个问题：与不完全竞争市场的国家和与完全竞争市场的国家建立关税同盟哪个伙伴更可取？
