Efficiency and Privatisation in Imperfectly Competitive Industries
挑战了私有化必然提高行业效率的传统观点，指出在寡头市场中，公共企业的存在可能通过竞争压力提升私营企业的效率，从而抵消自身效率较低的损失。
If a public firm is managed less efficiently than private producers facing similar conditions, then privatization will increase the overall efficiency of the industry and benefit society. This paper challenges this apparently innocuous conclusion. As long as the private firms' efficiency improves as a result of competition, then it will also be higher when they are subjected to "unfair" competition from a public oligopolist with no budget constraint. The author shows that it may happen that the loss inefficiency due to the relatively inefficient public firm is more than compensated by gains in the efficiency of the private firms.
