本文研究了面板数据模型在衡量配电公用事业成本效率方面的表现。不同的成本边界模型适用于1988年至1996年在瑞士运营的59个公用事业的样本。估计的系数和低效率的分数进行比较，在不同的规格。结果表明，虽然平均无效率是不敏感的计量经济学规格，效率排名不同的模型显着。合理低的样本外预测误差表明，面板数据模型可以作为一种预测工具，以缩小监管机构和受监管公司之间的信息差距。
This paper examines the performance of panel data models in measuring cost-efficiency of electricity distribution utilities. Different cost frontier models are applied to a sample of 59 utilities operating in Switzerland from 1988 to 1996. The estimated coefficients and inefficiency scores are compared across different specifications. The results indicate that while the average inefficiency is not sensitive to the econometric specification, the efficiency ranking varies significantly across models. The reasonably low out-of-sample prediction errors suggest that panel data models can be used as a prediction instrument in order to narrow the information gap between the regulator and regulated companies.
