Regional Differences in Nuclear and Fossil-Fuel Generation of Electricity
利用区域细分数据，发现不同地区的核电与化石燃料发电成本存在差异，并估算出比以往研究更小的化石燃料企业最小有效规模，对理解产能扩张、竞争和环保政策有参考价值。
Previous research on electric generation costs has mainly relied on economy-wide data. This study disaggregates a broad sample into regions known to have marked differences in fossil fuel availability, climate, regulatory effects, and other variables. We find differences exist in generation costs among the studied regions and nuclear power, using estimates of scale economies and other measures. We also find smaller minimum efficient size fossil-fuel firms than previous studies, based on recent cost information. This study provides insights into several industry structure issues, such as capacity expansion, competition, input costs, environmental policy, and transmission access.
