Airline Deregulation: The Cost Pieces of the Puzzle
利用航空公司面板数据，分解放松管制前后美国航空业成本变化中技术进步、规模经济与密度经济、投入价格的影响，发现放松管制通过优化航线结构促进了技术进步。
This paper analyzes cost changes in the U.S. airline industry in the pre- and postderegulation era using a panel data set of airlines. Specifically, it seeks to disentangle cost changes attributable to technical change, economies of scale and density, and input prices. The authors estimate a purely general index of industry technical change and in turn analyze its determinants. Despite the slowing of productivity growth in the 1980s, deregulation does appear to have stimulated technical change due to more efficient route structures.
