摘要：Severe traffic congestion is ubiquitous in large urban centers. This paper provides the first causal estimate of the relationship between traffic density and speed and optimal congestion charges using real-time fine-scale traffic data in Beijing. The identification relies on plausibly exogenous variation in traffic density induced by Beijing's driving restriction policy. Optimal congestion charges range from 5 to 39 cents per km depending on time and location. Road pricing would increase traff...

摘要：I examine whether lack of an individual market for prescription drug insurance causes individuals to delay retirement. Exploiting the 2006 introduction of Medicare Part D, which subsidized drug insurance for Americans over age 65, I use a triple-differences design that compares labor outcomes of individuals with retiree health insurance up to age 65 to those with insurance for life, before and after age 65, before and after 2006.I find that those with benefits only to age 65 decreased full-tim...

摘要：This paper explores whether private markets can incentivize environmental stewardship. We examine the consumer response to the 2010 BP oil spill and test how BP's investment in the 2000-2008 Beyond Petroleum green advertising campaign affected this response. We find evidence consistent with consumer punishment: BP station margins and volumes declined by 2.9 cents per gallon and 4.2 percent, respectively, in the month after the spill. However, pre-spill advertising significantly dampened the pr...

摘要：This paper studies human capital responses to the availability of the Deferred Action for Childhood Arrivals (DACA) program, which provides temporary work authorization and deferral from deportation for undocumented, high-school-educated youth. We use a sample of young adults that migrated to the United States as children to implement a difference-in-difference design that compares noncitizen immigrants (eligible) to citizen immigrants (ineligible) over time. We find that DACA significantly in...
