Grain shippers and political figures in North Dakota and nearby states have voiced concern that the dramatic increases in shipments of crude oil by rail have caused service delays and higher costs. We investigate the potential impact of crude shipments on grain markets accounting for harvest...

First-best pricing or assignment of property rights for rival and non-excludable goods is often infeasible. In a second-best setting where the social planner cannot limit total use, we show common-property resources can be over or under-consumed. This depends on whether the external benefits of...

This paper provides evidence of market power in the transportation of ethanol used in reformulated gasoline and alternative transportation fuels. I estimate a reduced form model for railroad route-level prices. My identification strategy instruments for railroad entry, controls for selection and...

Understanding how drivers respond to fuel price changes has important implications for highway congestion, accidents, carbon policy, local air pollution and taxation. We examine the under-explored relationship between fuel prices and carpooling. Using a simple theoretical model we show that...

A low carbon fuel standard (LCFS) seeks to reduce greenhouse gas emissions by capping an industry’s carbon emissions per unit of output. California has launched an LCFS for automotive fuels; others have called for a national LCFS. We show that this policy causes production of high-carbon...

We examine carpooling and driver responses to fuel price changes. Using a simple theoretical model, we show that traffic flows in mainline lanes unambiguously decrease when fuel prices increase, and this effect is stronger when the presence of a carpool lane provides a substitute to driving...
