Charging infrastructure is critical to electric vehicle (EV) adoption, but for chargers to be most useful, EV drivers need to know in real time where they are and whether they are working and available. We investigate the availability of real-time data from DC fast chargers on six major US...

Market power reduces equilibrium quantities and distorts production, typically causing welfare losses. However, as Buchanan (1969) noted, market power may mitigate overproduction from negative externalities. This paper examines this in the global oil market, where OPEC's market power affects oil...

We test whether more information about customers decreases racial bias. Our setting is the market for shared mobility services. Prior work by Ge et al. (2020) found that Uber drivers are two times more likely to cancel a ride if the passenger's name is one used predominantly by African...

We designed and conducted three randomized control trials in partnership with a large biopharmaceutical company operating over 160 plasma donation centers, with the aim of promoting sustainable behaviors in a workplace setting. Specifically, we focused on reducing operational errors that led to...

The marginal cost of electricity fluctuates hour-by-hour, yet retail customers typically face flat prices. Using data from all seven US wholesale markets and a new method to evaluate alternative rates set in advance that accounts for equilibrium price effects, we estimate efficiency gains from...

Mangroves provide vital ecosystem services like storm surge protection and carbon sequestration, but their coverage is rapidly declining. This study evaluates an environmental education program in the Dominican Republic, targeting children's attitudes, knowledge, behaviors, and willingness to...
