摘要

我们重新审视了Cicala(2015)的一个结果，并表明之前估计的美国电力重组对燃料采购的重大影响对异常值的存在并不稳健。使用稳健统计文献中的方法，我们估计效果小于先前估计的一半，并且在统计上与零没有差异。这种可靠的方法还将一家公司拥有的工厂视为异常值，这些工厂的煤炭合同甚至在重组讨论开始之前就被重新谈判了。(凝胶d83, o13, o33, q16)

When Does Regulation Distort Costs? Lessons from Fuel Procurement in US Electricity Generation: Comment

We revisit one of the results in Cicala (2015) and show that the previously estimated large and significant effects of US electricity restructuring on fuel procurement are not robust to the presence of outliers. Using methodologies from the robust statistics literature, we estimate the effect to be less than one-half of the previous estimate and not statistically different from zero. The robust methodology also identifies as outliers the plants owned by a single company whose coal contracts were renegotiated before discussions about restructuring even started.
