The United States consumed more petroleum-based liquid fuel per capita than any other OECD-high-income country - 30 percent more than the second-highest country (Canada) and 40 percent more than the third-highest (Luxemburg). This paper examines the main channels through which reductions in U.S....

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 examines the impact of industrial policies (IPs) on innovation in the global automobile industry. We compile the first comprehensive dataset linking global IPs with patent data related to the auto industry from 2008 to 2023. We document a major shift in policy focus: by 2022, nearly...

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...

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...

New car fleet fuel economy, weight and engine power have changed drastically since 1980. These changes represent both movements along and shifts in the "fuel economy/weight/engine power production possibilities frontier". This paper estimates the technological progress that has occurred since...

Using an original data source, this paper investigates the circumstances under which firms adopt computer numerical control (CNC), an important type of flexible automation which can significantly increase productivity, product variety and quality. The paper shows that arms'-length...
