We provide new insights regarding the finding that Medicaid increased emergency department (ED) use from the Oregon experiment. We find meaningful heterogeneous impacts of Medicaid on ED use using causal machine learning methods. The treatment effect distribution is widely dispersed, and the...

This paper examines the effect of increasing the length of senior high school education on immediate academic performance. We exploit a unique natural experiment that extended high school duration by one year in Ghana from 2007 to 2009. Following the policy’s reversal, the 2009 and 2010 high...

We investigate behavioral responses to a staggered disruption in the supply of prescription opioids across U.S. states: the introduction of electronic Prescription Drug Monitoring Programs (PDMPs). Using administrative datasets, we find PDMPs curtail the proliferation of prescription opioids....
