Despite increasing calls for reform many countries continue to provide subsidies for gasoline and diesel. This paper quantifies the external costs of global fuel subsidies using the latest available data and estimates from the World Bank and International Monetary Fund. Under preferred...

Adoption of real-time electricity pricing -- retail prices that vary hourly to reflect changing wholesale prices -- removes existing cross-subsidies to those customers that consume disproportionately more when wholesale prices are highest. If their losses are substantial, these customers are...

Information provision is a key element of government energy-efficiency policy, but the information that is provided is often too coarse to allow consumers to make efficient decisions. An important example is the ubiquitous yellow "EnergyGuide" label, which is required by law to be displayed on...

Transportation engineers are taught that as demand for travel goes up, this decreases not only speed but also the capacity of the road system, a phenomenon known as hypercongestion. We revisit this idea. There is no question that road systems experience periods in which capacity falls. However,...

Despite widespread agreement that a carbon tax would be more efficient, many countries use fuel economy standards to reduce transportation-related carbon dioxide emissions. We pair a simple model of the automakers' profit maximization problem with unusually-rich nationally representative data on...

We use demand and plant-level cost data to simulate competition in a restructured California electricity market. This approach recognizes that firms might have an incentive to restrict output in order to raise price and enables us to explicitly analyze each firm's ability to do so. We find that,...
