Alternative Regulatory Methods and Firm Efficiency: Stochastic Frontier Evidence from the U.S. Electricity Industry
利用随机前沿方法，研究美国电力市场中不同激励监管方案对燃煤和天然气发电机组技术效率的影响，发现与发电机绩效直接挂钩及修改燃料成本转嫁的方案能提升效率，其他方案则无显著效果。
The use of incentive regulation and other alternative regulatory programs in U.S. electricity markets has grown during the past two decades. Within a stochastic frontier framework, I investigate the effect of individual programs on the technical efficiency of a large set of coal and natural gas generation units. I find that those programs tied directly to generator performance and those that modify traditional fuel cost passthrough programs, to provide a greater incentive to reduce fuel costs, are associated with greater efficiency levels. Other programs have no statistical association with efficiency levels. © 2002 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
