摘要
在Hotelling模型的基础上,发展了一个简单双寡头模型来分析配额限制与质量选择的关系,考察了企业既选择数量竞争又选择价格竞争和两类成本类型下配额限制对质量的影响。基本结论是:本国企业和外国企业同时选择数量竞争和价格竞争会导致高质量产品同低质量产品之间总是存在质量溢价;本国企业和外国企业享有市场份额差异化,从而寡头市场并不一定完全覆盖质量区间;配额限制对质量选择的影响依赖于质量交叉效应。
In this paper,we develop a simple duopoly model of endogenous quality location with price and quantity competition based on Hotelling model to explore the relationship between quotas restriction and quality choice.We address the issue of competing in both prices and quantities within a simple differentiated duopoly where firms focus on the nature of cost function.Our key findings are the following: there always exists a "quality premium" between high quality product and low quality product;a differential ma...
