This paper investigates the neutrality of profit taxation in a mixed oligopoly where one (partially) public firm competes with private firms. We find that the neutrality of a profit tax is robust under a general cost and a general demand function as long as the degree of privatization is endogenously determined. This result is also true when product heterogeneity is considered under both Cournot and Bertrand competition. By contrast, if the degree of privatization is exogenously given, the profit tax neutrality holds only in the cases where the public firm is fully privatized or fully state-owned; otherwise, the neutrality breaks down.

混合寡头垄断中利润税的中性

本文研究了在一个(部分)公共公司与私人公司竞争的混合寡头垄断中利润税的中立性。我们发现,只要私有化程度是内生确定的,利润税的中性在一般成本和一般需求函数下是稳健的。当在古诺和伯特兰竞争下考虑产品异质性时,这个结果也是正确的。相比之下,如果私有化程度是外生给定的,则利润税中性仅在上市公司完全私有化或完全国有的情况下成立;否则,中立性就会瓦解。
