英文摘要:
This paper provides a comprehensive analysis of welfare measures when oligopolistic firms face multiple policy interventions and external changes under general forms of market demands, production costs, and imperfect competition. We present our results in terms of two welfare measures, namely, marginal cost of public funds and incidence, in relation to multi-dimensional pass-through. Our arguments are best understood with two-dimensional taxation where homogeneous firms face unit and ad valorem taxes. The first part of the paper studies this leading case. We show, e.g., that there exists a simple and empirically relevant set of sufficient statistics for the marginal cost of public funds, namely unit tax and ad valorem pass-through and industry demand elasticity. We then specialize our general setting to the case of price or quantity competition and show how the marginal cost of public funds and the pass-through are expressed using elasticities and curvatures of regular and inverse demands. Based on the results of the leading case, the second part of the paper presents a generalization with the tax revenue function specified as a general function parameterized by a vector of multi-dimensional tax parameters. We then argue that our results are carried over to the case of heterogeneous firms and other extensions.

中文摘要:
本文全面分析了寡头垄断企业在市场需求、生产成本和不完全竞争的一般形式下面临多重政策干预和外部变化时的福利措施。我们从两个福利指标,即公共资金的边际成本和发病率,以及多维传递的角度给出了我们的结果。我们的论点最好用二维税收来理解,在二维税收中,同质企业面临单位税和从价税。本文的第一部分研究了这一主要案例。例如,我们表明,对于公共资金的边际成本,存在一组简单且经验相关的充分统计数据,即单位税和从价税传递以及行业需求弹性。然后,我们将我们的一般设置专门用于价格或数量竞争的情况,并展示如何使用规则和反向需求的弹性和曲率来表示公共资金的边际成本和传递。本文第二部分根据主要案例的结果,将税收函数定义为一个由多维税收参数向量参数化的一般函数,并对其进行了推广。然后,我们认为我们的结果适用于异质企业和其他扩展的情况。
