Can financial incentives, public health messages and other behavioral nudges –approaches deployed by state and local governments, employers, and health systems – increase SARS-CoV-2 vaccination rates among the vaccine hesitant in the US? In mid-2021, we randomly assigned unvaccinated members...

We investigate the role of physician agency and competition in determining health care supply and patient outcomes. A 2005 change to Medicare fees had a large, negative impact on physician profit margins for providing chemotherapy treatment. In response to these cuts, physicians increased their...

We investigate the effect of pollution on worker productivity in the service sector by focusing on two call centers in China. Using precise measures of each worker's daily output linked to daily measures of pollution and meteorology, we find that higher levels of air pollution decrease worker...

We study the effect of outdoor air pollution on the productivity of indoor workers at a pear-packing factory. We focus on fine particulate matter (PM2.5), a harmful pollutant that easily penetrates indoor settings. We find that an increase in PM2.5 outdoors leads to a statistically and...
