This paper focuses on how changes in the economic and regulatory environment have affected production costs and product characteristics in the automobile industry. We estimate "hedonic cost functions" that relate product-level costs to their characteristics. Then we examine how this cost surface has changed over time and how these changes relate to changes in gas prices and in emission standard regulations. We also briefly consider the related questions of how changes in automobile characteristics, and in the rate of patenting, are related to regulations and gas prices.
本文聚焦于经济和监管环境的变化如何影响汽车行业的生产成本和产品特性。我们估计了将产品层面成本与其特性相关联的“享乐成本函数”。然后我们考察了这一成本曲面如何随时间变化，以及这些变化如何与天然气价格和排放标准法规的变化相关。我们还简要考虑了汽车特性变化以及专利申请率变化如何与法规和天然气价格相关的相关问题。
