报告内容简介：We consider a mixed duopoly service system in which a profit-maximizing private service provider (SP) competes against a welfare-maximizing public SP (or equivalently, a social planner). The two SPs’ service quality is differentiated and customers are heterogeneous on quality taste. We first consider the scenario where premium service is provided by the private SP and the regular one by the public SP. We show that welfare can be improved if the public SP is privatized and there exists an optimal level of privatization for the public SP

in terms of welfare maximization; under some conditions, full privatization is optimal. We then extend our analysis to the other scenario where the premium service is provided by the public SP and the regular one by the private SP, and obtain similar findings. By comparing the maximal welfare of the two scenarios, we find that the latter scenario prevails when the service rate or/and the service quality of the premium service is/are relatively high. Furthermore, under the prevailed scenario, partial privatization is adopted.
