Abstract

The US Federal Aviation Administration (FAA) has implemented a large-scale multi-year infrastructure program called the Next Generation Air Transportation System (NextGen) to improve air transportation efficiency. To assess its efficacy, we estimate how NextGen projects completed between 2014 and 2017 affected air travel time and delays using an event study approach. We find sizable time savings in air travel time and delays from implementing NextGen. The time savings are more substantial for flights that experience unexpected shocks, such as poor weather and prior delays. In contrast, while NextGen seemed to close the performance gap between the hub and non-hub carriers generated by market power, the effect was short-lived and quickly reversed. Although we also find some small social benefits from carbon emission reductions, we cannot rule out that aggregate carbon emissions may have increased due to a rebound effect.

采用下一代航空运输系统(NextGen)对航空旅行性能的影响
美国联邦航空管理局(FAA)实施了一项名为“下一代航空运输系统”(NextGen)的大规模多年基础设施计划,以提高航空运输效率。为了评估其疗效,我们使用事件研究方法估计了2014年至2017年间完成的NextGen项目对航空旅行时间和延误的影响。我们发现,实施NextGen在航空旅行时间和延误方面节省了大量时间。对于经历意外冲击(如恶劣天气和先前延误)的航班来说,节省的时间更为可观。相比之下,虽然NextGen似乎缩小了由市场力量产生的集线器和非集线器运营商之间的性能差距,但这种影响是短暂的,并很快逆转。尽管我们也发现碳减排带来了一些小的社会效益,但我们不能排除总碳排放量可能因反弹效应而增加的可能性。

期刊介绍: Regional Science and Urban Economics facilitates and encourages high-quality scholarship on important issues in regional and urban economics. It publishes significant contributions that are theoretical or empirical, positive or normative. It solicits original papers with a spatial dimension that can be of interest to economists. Empirical papers studying causal mechanisms are expected to propose a convincing identification strategy.
