Nearly a thousand officer-involved killings occur each year in the United States. This paper documents the large, racially disparate impacts of these events on the educational and psychological well-being of Los Angeles public high school students. Exploiting hyperlocal variation in how close students live to a killing, I find that exposure to police violence leads to persistent decreases in GPA, increased incidence of emotional disturbance, and lower rates of high school completion and college enrollment. These effects are driven entirely by black and Hispanic students in response to police killings of other minorities and are largest for incidents involving unarmed individuals.

Implementation of policies at AMCs that restricted pharmaceutical detailing between 2006 and 2012 was associated with modest but significant reductions in prescribing of detailed drugs across 6 of 8 major drug classes; however, changes were not seen in all of the AMCs that enacted policies.

The treatment of pediatric depression is controversial because it includes substantial prescribing of drugs for uses that have not been approved by the Food and Drug Administration ("off label") and are not evidence based. Some academic medical centers (AMCs) restrict "detailing" by pharmaceutical sales representatives, or the promoting of drugs directly to physicians via sales calls, to reduce the effect of such marketing on physician prescribing. With data from thirty-one geographically diverse AMCs and their affiliated hospitals, we used a difference-in-differences model to estimate the effect of anti-detailing policies on off-label prescribing of antidepressants and antipsychotics by pediatricians and by child and adolescent psychiatrists in the period January 2006-June 2009. We found that after the introduction of such policies, prescriptions for off-label use of promoted drugs fell by 11 percent, consistent with the ongoing presence of off-label marketing to physicians. Prescriptions for on-label use of promoted drugs fell by 34 percent after the adoption of the policies. Conversely, prescriptions for on-label use of nonpromoted drugs rose by 14 percent, and those for offlabel use of nonpromoted drugs rose by 35 percent. These results suggest that pharmaceutical sales representatives promoted drugs not approved for pediatric use and that policies that restrict detailing by those representatives reduced such off-label prescribing.

In 2013, the Supreme Court struck down parts of the Voting Rights Act that mandated federal oversight of election laws in discriminatory jurisdictions, prompting a spate of controversial new voting rules. Utilizing difference-in-differences to examine the act’s 1975 revision, I provide the first estimates of the effects of “preclearance” oversight. I find that preclearance increased long-run voter turnout by 4–8 percentage points, due to lasting gains in minority participation. Surprisingly, Democratic support dropped sharply in areas subject to oversight. Using historical survey and newspaper data, I provide evidence that this was the result of political backlash among racially conservative whites. (JEL D72, J15, K16)
