We empirically investigate the impact of COVID-19 shutdowns on domestic violence using incident-level data on both domestic-related calls for service and crime reports of domestic violence assaults from the 18 major US police departments for which both types of records are available. Although we confirm prior reports of an increase in domestic calls for service at the start of the pandemic, we find that the increase preceded mandatory shutdowns, and there was an incremental decline following the government imposition of restrictions. We also find no evidence that domestic violence crimes increased. Rather, police reports of domestic violence assaults declined significantly during the initial shutdown period. There was no significant change in intimate partner homicides during shutdown months and victimization survey reports of intimate partner violence were lower. Our results fail to support claims that shutdowns increased domestic violence and suggest caution before drawing inference or basing policy solely on data from calls to police.

Around the world, policymakers and news reports have warned that domestic violence (DV) could increase as a result of the COVID-19 pandemic and the attendant restrictions on individual mobility and commercial activity. However, both anecdotal accounts and academic research have found inconsistent effects of the pandemic on DV across measures and cities. We use high-frequency, real-time data from Los Angeles on 911 calls, crime incidents, arrests, and calls to a DV hotline to study the effects ofCOVID-19 shutdowns on DV. We find conflicting effects within that single city and even across measures from the same source. We also find varying effects between the initial shutdown period and the onefollowing the initial re-opening. DV calls to police and to the hotline increased during the initial shutdown, but DV crimes decreased, as did arrests for those crimes. The period following re-opening showeda continued decrease in DV crimes and arrests, as well as decreases in calls to the police and to the hotline. Our results highlight the heterogeneous effects of the pandemic across DV measures and caution against relying on a single data type or source.

We study the impact of the integration of women in U.S. policing between the late 1970s and early 1990s on violent crime reporting and domestic violence (DV). Along these two key dimensions, we find that female officers improved police quality. Crime victimization data reveal that as female representation increases among officers in an area, violent crimes against women in that area, and especially DV, are reported to the police at significantly higher rates. There are no such effects for violent crimes against men or from increases in the female share of civilian police employees. Furthermore, increases in female officer shares are followed by significant declines in rates of intimate partner homicide and non-fatal domestic abuse. These effects are all consistent between fixed effects models with controls for economic and policy variables and models that focus exclusively on increases in female police employment driven by externally imposed affirmative action plans following litigation for employment discrimination.

This paper develops a novel field experiment to test the implicit prediction of tournament theory thatcompetition increases work time and can therefore contribute to the long work hours required in eliteoccupations. A majority of workers in the treatment without explicit financial incentives worked pastthe minimum time, but awarding a tournament prize increased work time and effort by over 80% andlowered costs of effort or output by over a third. Effort was similar with alternative (piece rate, low-prizetournament) bonuses. Men worked longer than women in the high-prize tournament, but for the sameduration in other treatments.

Affirmative action is often criticized for causing reverse discrimination and lowering thequalifications of those hired under the policy. However the magnitude of such adverse effectsdepends on whether the best suited candidate is hired absent the policy. Indeed affirmative actionmay compensate for the distortion discrimination imposes on the selection of candidates. Thispaper asks whether affirmative action can have a similar corrective impact when qualifiedindividuals fail to apply for a job. We evaluate the effect of introducing a gender quota in anenvironment where high performing women fail to enter competitions they can win. We showthat guaranteeing women equal representation among winners increases their entry. The responseexceeds that predicted by the change in probability of winning, and is in part driven by womenbeing more willing to compete against other women. The consequences are substantial as theboost in supply essentially eliminates the anticipated costs of the policy.

Using data on young men from the National Education Longitudinal Survey, this paperinvestigates the relationship between childhood misbehavior and later education and labor marketoutcomes. The main finding is that eighth-grade misbehavior is important for earnings overand above eighth-grade test scores. Moreover, controlling for educational attainment, childhoodmisbehavior is associated with earnings at all educational levels, whereas achievement test scoresare related to earnings only for young men with postsecondary degrees. Possible explanations forthe association between eighth-grade misbehavior and economic success are explored.

This paper exploits variation in the timing and outcomes of employment discrimination lawsuits against U.S. law enforcement agencies to estimate the cumulative and persistent employment effects of temporary externally imposed affirmative action (AA). We find that AA increased black employment at all ranks by 4.5 to 6.2 percentage points relative to national trends. We also find no erosion of these employment gains in the fifteen years following AA termination, although black employment growth was significantly lower in departments after AA ended than in departments whose plans continued. For women, in contrast, we find only marginal employment gains at lower ranks.

This paper provides evidence that scores on simple, low-stakes tests are associated with future economic success because the scores also reflect test takers' personality traits associated with their level of intrinsic motivation. To establish this, I use the coding speed test that was administered without incentives to participants in the National Longitudinal Survey of Youth (NLSY). I show that, controlling for cognitive ability, the coding speed scores are correlated with future earnings of male NLSY participants. I provide evidence that the coding speed scores relate to intrinsic motivation. I show that the scores of the highly motivated, though less educated, group (potential recruits to the U.S. military), are higher than the NLSY participants' scores. I use controlled experiments to show directly that intrinsic motivation is an important component of the unincentivized coding speed scores and that it relates to test takers' personality traits.
