This paper considers the treatment of co-benefits in benefit-cost analysis of federal air quality regulations. Using a comprehensive data set on all major Clean Air Act rules issued by the Environmental Protection Agency over the period 1997-2019, we show that (1) co-benefits make up a...

Economists have for decades recommended that carbon dioxide and other greenhouse gases be taxed--or otherwise priced--to provide incentives for their reduction. The United States does not have a federal carbon tax; however, many state and federal programs to reduce carbon emissions effectively...

We make four main contributions in this paper related to the theory and practice of benefit cost analysis (BCA). First, we show that most BCAs of policy interventions do not consider the welfare consequences in secondary markets, where goods or services can be complements or substitutes to those...

Efficient electricity pricing involves two-part tariffs: a volumetric price equal to the marginal cost of producing an additional kilowatt hour (kWh) and a fixed fee to cover any remaining fixed costs. In this paper we explore how US electricity regulators depart from this simple two-part tariff...

Regulators attest that tightened energy efficiency standards save consumers money. Efficient light bulbs, appliances, and vehicles cost more upfront but reduce energy expenses by more than enough to compensate. We use survey data on American cars and their drivers to examine whether individual...

The US has been a global leader in regulating local air pollution and a global laggard in regulating greenhouse gases (GHGs). For decades, critics of US policy have expressed fears that stringent US regulations on local air pollution would lead to pollution havens overseas. Prior research,...

We evaluate the economic and environmental consequences of taxes on imported goods based on their carbon content. The analysis uses the simplest possible partial equilibrium framework, with one small open economy and a global pollution externality. It relies on graphs of supply and demand,...

Many governments and businesses would like to minimize or eliminate the greenhouse gases that result from their purchases of power from electricity grids. Because electricity flows cannot be traced from purchasers back to specific generators, some regulators and users have proposed an...

We estimate the impacts of temperature on alleged and substantiated child maltreatment among young children using administrative data from state child protective service agencies. Leveraging short-term weather variation, we find increases in maltreatment of young children during hot periods. We...

We use state-of-the-art, satellite-based PM2.5 estimates to assess the extent to which the EPA's existing, monitor-based measurements over- or under-estimate true exposure to PM2.5 pollution. Treating satellite-based estimates as truth implies a substantial number of "policy...
