摘要

本研究利用批发电力池中的价格投标信息和电力市场文献中描述的经验技术，确定了上市公司在哥伦比亚市场中的市场力量缓解效应。研究结果表明，虽然私营企业行使的市场权力比利润最大化模型预测的要少，但私营企业和公营企业在行使单方面市场权力方面存在显著差异。这些发现支持了上市公司市场力量缓解效应的假设。

Mixed Oligopoly and Market Power Mitigation: Evidence from the Colombian Wholesale Electricity Market*

Using information on price bids in wholesale electricity pools and empirical techniques described in the literature on electricity markets, this study identifies the market power mitigation effect of public firms in the Colombian market. The results suggest that while private firms exercise less market power than is predicted by a profit-maximization model, there are marked differences between private and public firms in their exercise of unilateral market power. These findings support the hypothesis of the market power mitigation effect of public firms.

期刊介绍： First published in 1952, the Journal of Industrial Economics has a wide international circulation and is recognised as a leading journal in the field. It was founded to promote the analysis of modern industry, particularly the behaviour of firms and the functioning of markets. Contributions are welcomed in all areas of industrial economics including: - organization of industry - applied oligopoly theory - product differentiation and technical change - theory of the firm and internal organization - regulation - monopoly - merger and technology policy Necessarily, these subjects will often draw on adjacent areas such as international economics, labour economics and law.
