Automobile Externalities and Policies

Oct 30, 2007 | Ian W.H. Parry, Margaret A. Walls, Winston Harrington


This paper reviews theoretical and empirical literature on the measurement of the major automobile externalities, namely local pollution, global pollution, oil dependence, traffic congestion and traffic accidents. It then dicusses the rationale for traditional policies to address these externalities, including fuel taxes, fuel economy standards, emissions standards and related policies. Finally, it discusses emerging, more finely-tuned policies, such as congestion pricing and pay-as-you-drive insurance, that have become feasible with advances in electronic metering technology.
