Tinbergen's seminal work showed that we need as many policy instruments as there are market failures to address. In practice, however, regulatory power is often constrained, making it difficult or impossible to implement the first-best policy portfolio. We analyze analytically and numerically...

Efforts to limit cumulative emissions over the next century may be partially thwarted by the responses of fossil fuel suppliers. Current price-cost margins for major reserves are ample, leaving scope for significant price reductions if climate policies reduce demand for fossil fuels through...

Carley and Konisky (2021) provide a compelling argument around the importance of equity and social justice in climate policy. We agree that carbon pricing alone cannot achieve every social objective, but we do view carbon pricing as compatible with and even furthering equity objectives by...

Efforts to limit cumulative emissions over the next century may be partially thwarted by the responses of fossil fuel suppliers. Current price-cost margins for major reserves are ample, leaving scope for significant price reductions if climate policies reduce demand for fossil fuels through...

Estimates of marginal abatement costs for reducing carbon emissions derived from major economic-energy models vary widely. Controlling for policy regimes, we use meta-analysis to examine the importance of structural modeling choices in explaining differences in estimates. The analysis indicates...

Project-based mechanisms for emissions reductions credits, like the Clean Development Mechanism, pose important challenges for policy design because of several inherent characteristics. Participation is voluntary, so it will not occur without sufficient credits. Evaluating reductions requires...

Project-based mechanisms for emissions reductions credits, like the Clean Development Mechanism, pose important challenges for policy design because of several inherent characteristics. Participation is voluntary. Evaluating reductions requires assigning a baseline for a counterfactual that...

Some studies of renewable portfolio standards find that regulations increase generation costs; others find that reduced demand for nonrenewable energy sources lowers natural gas prices and that electricity prices follow. This paper presents reasoning for why these predictions can vary in the...

Policies to promote energy efficiency in household appliances have different impacts, depending on the structure of market supply. If provision is perfectly competitive, markets will offer the variety of energy efficiency levels that consumers demand. However, if producers can price...

Myriad policy measures aim to reduce greenhouse gas emissions from the electricity sector, promote generation from renewable sources, and encourage energy conservation. To what extent do innovation and energy efficiency (EE) market failures justify additional interventions when a carbon price is...
