Reconciling domestic and global estimates of the social cost of carbon will be a necessary challenge to construct effective climate policy, especially to the extent that other countries look to the United States for climate leadership.
Bike-share users may trade off their time to save money by going out of the way to avoid a price increase. We estimate how users value time in this context: commuters value time more than recreational users, but neither group responds to changes in price.
To credibly measure the effectiveness of public policies, when feasible, pilot programs with randomized control groups should be considered and rolled out first, to facilitate reliable program evaluations—before widespread implementation.
Urban bike sharing is gaining popularity for its purported health, environmental, and traffic congestion benefits. Evidence from Washington, DC, one of the most congested US cities, suggests that the Capital Bikeshare program reduces traffic congestion.
An analysis of the impact of water scarcity on the electricity sector in the United States demonstrates how water scarcity shifts electricity production from hydropower to natural gas, resulting in increased carbon dioxide emissions.
When consumers value both the overall level of environmental quality and their own contributions to that end, policymakers can encourage the optimal provision of public goods by incorporating pro-environmental preferences into regulatory design.
Individual municipal water systems are responsible for providing clean water for hundreds of thousands of people, yet aging pipes lead to water main breaks that not only disrupt water service, but also affect traffic—but at what cost?
