The true net environmental benefit of an electric vehicle (EV) is measured relative to the vehicle that an EV buyer would have bought and driven had they not opted for an EV. This "counterfactual" vehicle cannot be observed, but its fuel economy can be estimated. We use quasi-experimental...

In the absence of a national carbon tax, household driving and electricity consumption impose social costs. Suburbanites drive more and consume more electricity than center city residents. If more suburbanites purchase electric vehicles (EV) and install solar panels, then their greenhouse gas...

Can directed technical change be used to combat climate change? We construct new firm-level panel data on auto industry innovation distinguishing between "dirty" (internal combustion engine) and "clean" (e.g. electric and hybrid) patents across 80 countries over several decades. We show that...

This paper develops and estimates an industry equilibrium model of manufacturing plants in the Korean electric motor industry from 1991 to 1996. Plant-level decisions on R&D, physical capital investment, entry, and exit are integrated in a dynamic setting with knowledge spillovers. We use a...

This paper identifies and quantifies major determinants of future electric vehicle (EV) demand in order to inform widely-held aspirations for market growth. Our model compares three channels that will affect EV market share in the United States from 2020-2035: intrinsic (no-subsidy) EV demand...

Electric vehicles are declining in cost so rapidly that they may claim a large share of the vehicle market by 2030. This paper examines a set of practical regulatory design considerations for fuel-economy standards or greenhouse gas standards in the context of highly uncertain electric vehicle...

Electric vehicles (EVs) powered by renewable electricity are a centerpiece of efforts to decarbonize transportation. EV advocates also claim benefits from local pollution reductions, lower life-cycle costs to consumers, and improved energy security. We examine the theory and evidence behind...

This paper presents evidence that gasoline prices have a larger effect on demand for electric vehicles (EVs) than electricity prices in California. We match a spatially-disaggregated panel dataset of monthly EV registration records to detailed records of gasoline and electricity prices in...

Electric vehicles have a unique potential to transform personal transportation. We analyze the transition to electric vehicles with a dynamic model that captures the falling costs of producing electric vehicles, the decreasing pollution from electricity generation, the increasing...

The emissions reductions from the adoption of a new transportation technology depend on the emissions from the new technology relative to those from the displaced technology. We evaluate the emissions reductions from electric vehicles (EVs) by identifying which vehicles would have been purchased...
