|November 2016||An Economic Analysis of U.S Airline Fuel Economy Dynamics from 1991 to 2015|
with Matthew E. Kahn: w22830
Airline transport generates a growing share of global greenhouse gas emissions but as of late 2016, this sector has not faced U.S. fuel economy or emissions regulation. At any point in time, airlines own and lease a set of durable vehicles and have invested in human and physical capital and an inventory of parts to maintain these vehicles. Each airline chooses whether to scrap and replace airplanes in their fleet and how to utilize and operate their fleet of aircraft. We model these choices as a function of real jet fuel prices. When jet fuel prices are higher, airlines fly fuel inefficient planes slower, scrap older fuel inefficient planes earlier and substitute miles flown to their more fuel efficient planes.
|March 2014||Public Transit Bus Procurement: The Role of Energy Prices, Regulation and Federal Subsidies|
with Shanjun Li, Matthew E. Kahn: w19964
The U.S. public transit system represents a multi-billion dollar industry that provides essential transit services to millions of urban residents. We study the market for new transit buses that features a set of non-profit transit agencies purchasing buses primarily from a few domestic bus makers. Unlike private vehicles, the fuel economy of public buses is irresponsive to fuel price changes. To understand this finding, we build a model of bus fleet management decisions of local transit agencies that yields testable hypotheses. Our empirical analysis of bus fleet turnover and capital investment suggests that transit agencies: (1) do not respond to energy prices in either their scrappage or purchase decisions; (2) respond to environmental regulations by scrapping diesel buses earlier and sw...
