摘要

我们独特地考察了上游混合双寡头在下游市场的连续性中进行空间价格歧视。这些市场中的垄断企业面临着弹性的最终需求,造成了双重边缘化。相对于其私人竞争对手,这家上游上市公司面临着成本劣势,随着其部分私有化,成本劣势有所下降。我们表明,相对于私人双寡头垄断,当完全上市的公司没有过度低效且差异足够大时,它可以提高社会福利。我们还表明,无论何时,都存在最佳程度的部分私有化,这可以更好地协调生产成本和定价扭曲之间的权衡。

Spatial price discrimination in a mixed duopoly input market

We uniquely examine an upstream mixed duopoly engaging in spatial price discrimination across a continuum of downstream markets. The monopoly firms in those markets face elastic final demand creating double marginalization. The upstream public firm faces a cost disadvantage relative to its private rival that declines as it is partially privatized. We show that the fully public firm improves social welfare relative to a private duopoly when it is not overly inefficient and when differentiation is sufficiently large. We also show that whenever this is the case, there exists an optimal degree of partial privatization that better aligns the trade-off between production costs and pricing distortions.

期刊介绍: Regional Science and Urban Economics facilitates and encourages high-quality scholarship on important issues in regional and urban economics. It publishes significant contributions that are theoretical or empirical, positive or normative. It solicits original papers with a spatial dimension that can be of interest to economists. Empirical papers studying causal mechanisms are expected to propose a convincing identification strategy.
