In a field experiment tracking 390 electric vehicles minute-by-minute, we show that incentives reduce charging by 17%—27% during peak times and increase it by 34% during midday when solar generation is highest. Peak charging decreases at home, while midday charging rises out of the home....

Governments monitor air quality for regulatory purposes and, more recently, to provide information so individuals can act to lower their exposure to air pollution. Recent developments in low-cost technologies have also led to private adoption of air-quality monitors that produce publicly...

We use an experiment to test whether consumers optimally acquire information on energy costs in appliance markets where, like many contexts, consumers are poorly informed and make mistakes despite freely available information. To test for optimal information acquisition we compare the average...

We provide evidence of an energy efficiency gap in China. Using an incentivized field experiment, we document that providing information to consumers on the energy costs of lightbulbs significantly affects their willingness to pay for energy efficient bulbs. Unlike previous literature, we do not...

I test whether economic incentives dampen peer effects in public-good settings. I study how a visible and subsidized contribution to a public good (installing solar panels) affects peer contributions that are neither subsidized nor visible (electing green power). Exploiting spatial variation in...

We exploit novel data from brain-training games to examine the impacts of air pollution on a comprehensive set of cognitive skills of adults. We find that exposure to particulate matter (PM2.5) impairs adult cognitive function, and that these effects are largest for those in prime working age....

Axbard and Deng (2024) exploit the rollout of new pollution monitors in China in 2015 in 177 medium-size cities to study the effect of air-quality monitors on enforcement actions by local governments and air quality. In their main difference-in-difference analysis, they identify the change in...
