Corruption, Quasi-Rents, and the Regulation of Electric Utilities
研究美国州级电力监管的采纳原因，发现数据更支持监管是为了保护准租金（防止腐败）而非争夺垄断租金的负和博弈。
Was the adoption of state utility regulation the result of a negative-sum competition among special interest groups vying for the monopoly rents created by regulation or a positive-sum elimination of corruption arising from appropriable quasi-rents? Previous empirical studies of the adoption of regulation have assumed the former. Using discrete hazard analysis, this study considers the latter and finds the data more consistent with the positive-sum protection of quasi-rents than the negative-sum creation and appropriation of monopoly rents.
