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...

This paper explores the interactions between taxes on work-related traffic congestion and pre-existing distortionary taxes in the labor market. A congestion tax raises the overall costs of commuting to work and discourages labor force participation. The resulting welfare loss in the labor market...

The presence of preexisting tax distortions, and the form of revenue recycling, can crucially affect the size - and possibly even the sign - of the welfare effect of road pricing schemes. The efficiency gains from recycling congestion tax revenues in other tax reductions can amount to several...

In Becker (1965) and neoclassical microeconomic theory the value of time is a constant fraction of the hourly wage. When taken to data, however, this value departs from theoretical predictions, and appears to vary with the amount of time saved. By observing drivers on freeways opting to enter...
