Product Differentiation and Oligopoly in International Markets: The Case of the U.S. Automobile Industry
构建并估计了美国汽车产业模型，利用消费者调查微观数据估计需求，将产业视为产品差异化的寡头垄断，并用反事实模拟分析自愿出口限制和汇率传递效应。
This paper develops and estimates a model of the U.S. Automobile Industry. On the demand side, a discrete choice model is adopted, that is estimated using micro data from the Consumer Expenditure Survey. The estimation results are used in conjunction with population weights to derive aggregate demand. On the supply side, the automobile industry is modelled as an oligopoly with product differentiation. Equilibrium is characterized by the first order conditions of the profit maximizing firms. The estimation results are used in counterfactual simulations to investigate two trade policy issues: the effects of the VER, and exchange rate pass-through.
