Given that I focus on hyperlocal effects among high schoolers and do not account for effects on younger children or for other returns to schooling (Lochner and Moretti 2004), this figure likely underestimates the total educational costs of police killings. While Burdick-Will (2013) finds that violence has little effect on grades, that study and others (Burdick-Will et al. It is also possible that even among students that knew about an incident, those that personally knew the deceased or directly witnessed the violence may be more negatively affected.

QUARTERLY JOURNAL OF ECONOMICS. Rather than complying, Aguilar grabbed an officerâs gun and was shot by the officerâs partner. Per Callaway and SantâAnna (2019), I interrogate this concern by estimating separate event studies for each treatment cohort (defined by the semester a student was first exposed to a police killing). dev. 1997) and Frank Jude in Milwaukee (Desmond, Papachristos, and Kirk 2016) or the lethal shooting of Michael Brown in Ferguson (Gershenson and Hayes 2018).3 However, such landmark events were often tipping points for larger social movements, like widespread riots in Los Angeles and Black Lives Matter in Ferguson. My findings suggest that on average, each officer-involved killing in Los Angeles caused three students of color to drop out of high school. ), low-dosage tutoring (0.015 std. This analysis, which draws on responses from LAUSDâs SES, suggests that exposure to police violence does affect studentsâ underlying psychological well-being. This article seeks to document the short- and long-run consequences of police killings on the educational and psychological well-being of inner-city youth. Editors and Editorial Board Submission Information QJAE Archives A primary threat to identification is that unobserved changes in local crime or policing activity may explain both the presence of police shootings and changes in academic performance. The Quarterly Journal of Economics is the oldest professional journal of economics in the English language. Column (1) presents my base specification controlling for time trends at the census block group level. © The Author(s) 2020. Please check the relevant section in this Guide for Authors for more details. For example, in a 2015 national survey, 85% of black respondents and 63% of Hispanic respondents reported believing that police are more likely to use force against a black person. The data also contains each studentâs last reported home address while enrolled at LAUSD.14, The data set includes a host of short- and long-run measures of academic achievement. Sharkey Patrick T., Tirado-Strayer Nicole, Papachristos Andrew V., Cybele Raver C.. Sigelman Lee, Welch Susan, Bledsoe Timothy, Combs Michael. Estimates then converge to 0 for students in higher expected grades. Second, this article complements a growing body of research demonstrating how perceived discrimination may lead to âself-fulfilling propheciesâ in education (Carlana 2019), labor markets (Glover, Pallais, and Pariente 2017), and health care (Alsan and Wanamaker 2018).7 While empirical evidence of racial bias is mixed (Nix et al. Although data on homicides are available for the entire sample, information for arrests and nonhomicide crimes is only available from 2010 onward. The Journal Impact 2019-2020 of Quarterly Journal of Economics is 12.810, which is just updated in 2020.Compared with historical Journal Impact data, the Metric 2019 of Quarterly Journal of Economics grew by 43.93 %.The Journal Impact Quartile of Quarterly Journal of Economics is Q1.The Journal Impact of an academic journal is a scientometric Metric that reflects the yearly … The estimation sample consists of the pooled set of student-date observations within 10 days and three miles of each police killing, where distance and relative time are redefined within each window. 2 QUARTERLY JOURNAL OF ECONOMICS necessary permits. Column (7) excludes students who entered LAUSD in the 10th to 12th grades. Following shootings, GPA decreases significantly among students living nearby. The omitted period is the last semester prior to treatment. The Journal Surveys project is a way for scholars to provide feedback about their experiences with journals. If they were, one would expect the largest spillovers to come from killings of individuals who shot at others. Journal of Criminal Law and Criminology,especially Blumstein and Rosenfeld [1998], Kelling and Bratton [1998], and Donohue [1998]. Control students are those whose nearest killing during high school was between 0.50 and 3 miles away. between 0.50 and 3 miles). In contrast, an entrepreneur in Canada can finish the process in two days by paying US$280 in fees and completing only two procedures. As corroboration, I find that exposed students are 15% more likely to be classified with emotional disturbanceâa chronic learning disability associated with PTSD and depressionâand twice as likely to report feeling unsafe in their neighborhoods the following year. Magnitudes increase modestly when excluding multiple-treaters and when narrowing the treatment bandwidth, consistent with larger effects for closer students. It also provides causal evidence in support of recent work by Bor et al. The figure shows DD coefficients and 95% confidence intervals from estimation of equation (1) on semester GPA (mean = 2.08), replacing time to treatment indicators with a posttreatment dummy. In particular, nearby students are twice as likely to report feeling unsafe outside of school the year after a killing. A second reason for this skepticism is the complexity of the ... time … Effects then gradually dissipate, reaching insignificance five semesters after exposure. Given the frequency of the latter, I employ a modified event study model to compare the short-run effects of police and criminal gun-related killings. Thus, observations in the final data set are uniquely identified by student, i, and expected grade, g, with treatment status for observation (i, g) determined by the studentâs distance to the nearest killing in that expected grade.44 As an example, consider a student who entered the ninth grade in fall 2007 and experienced a killing 0.20 miles away in fall 2009, a killing 1.5 miles away in fall 2011, and two killings in fall 2013, one 0.20 miles away and one 1.5 miles away. If awareness of police killings is limited to local communities or if the effects are otherwise correlated with geographic proximity (due to social networks, visceral effects of witnessing the incident, etc. 2 QUARTERLY JOURNAL OF ECONOMICS necessary permits. The sample is restricted to entering 9th graders with expected graduation dates from spring 2006 to spring 2016 (i.e., those students whose expected 9th- to 12th-grade years fall entirely within the sample period.) This supports the plausible exogeneity of police killings, after conditioning on block groupâtime. Of particular interest to this study, the survey includes three questions examining feelings of school and neighborhood safety.17. QUARTERLY JOURNAL OF ECONOMICS Vol.CXVII February 2002 Issue1 THE REGULATION OF ENTRY* SIMEONDJANKOV RAFAELLAPORTA FLORENCIOLOPEZ-DE-SILANES ANDREISHLEIFER We present new data on the regulation of entry of start-up ” rms in 85 countries. Consistent with this, I find that the marginal effects of criminal homicides are only half as large as those of police killings. At the same time, the four largest urban riots in recent U.S. history were all triggered by acts of police violence (DiPasquale and Glaeser 1998).1 Experiences with aggressive policing have been linked to unfavorable attitudes toward law enforcement, particularly among racial minorities, whose lifetime odds of being killed by police are as high as 1 in 1,000 (Skolnick and Fyfe 1993; Weitzer and Tuch 2004; Brunson and Miller 2005).2 These attitudes are, in turn, correlated with fear (Hale 1996; Renauer 2007; Boyd 2018), perceived discrimination (Brunson 2007; Carr, Napolitano, and Keating 2007), and institutional distrust (Bobo and Thompson 2006; Kirk and Papachristos 2011). However, results are robust to coding absenteeism based on all classes on a given date. forthcoming), my findings suggest that decreases in GPA may be driven in part by psychological trauma. (2018), who examine cross-sectional survey data and find that police killings of blacks are linked to lower self-reported mental health among black men in the same state.33. To better understand the mechanisms behind these effects, I exploit rich heterogeneity in the data. All appendix tables and figures mentioned in the text are included in the Online Appendix. From 2002 to 2016, L.A. County experienced nearly 9,500 gun-related homicides. Desmond Matthew, Papachristos Andrew V., Kirk David S.. Edwards Frank, Lee Hedwig, Esposito Michael. y_{i,t} &= & \delta _i + \lambda _{n,t} + \omega _{c,t} + \beta _{BH} Post \times Shoot \times BlackHispanic \nonumber \\ For example, it is possible that the former are particularly harmful because they occur in more disadvantaged areas or because the person killed was more likely to have been from the neighborhood or known in the community. Relative to the full sample, students who lived within 0.50 miles of an incident during high school (i.e., the treatment group) are more likely to be Hispanic and qualify for free lunch, and less likely to speak English at home or to have college-educated parents. Charges were not pressed in that instance until December 2018, after the end of the sample period. 130 November 2015 Issue 4 THEHIGH-FREQUENCYTRADINGARMSRACE:FREQUENT BATCH AUCTIONS AS A MARKET DESIGN RESPONSE* Eric Budish Peter Cramton John Shim The high-frequency trading arms race is a symptom of flawed market design. 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. Control students are those whose nearest killing during high school was between 0.50 and 3 miles away. The effects on high school completion come almost entirely from dropouts. Desmond Ang, The Effects of Police Violence on Inner-City Students, The Quarterly Journal of Economics, , qjaa027, https://doi.org/10.1093/qje/qjaa027. Black circles represent estimation on black and Hispanic students. Results are robust to dropping these students from the graduation and college enrollment analysis. Panel A estimates effects separately for each student race subsample (i.e, blacks, Hispanics, and the pooled sample of whites and Asians). The figure shows DD coefficients and 95% confidence intervals from estimation of a modified version of equation (4), replacing the full set of expected grade at treatment interactions with a simple posttreatment dummy set to 1 for treated observations in expected grade â¤12. comprises students living between 0.50 and 3 miles from an incident. The sample contains the pooled cross-section of students living within three miles of a killing from expected grades 9 through 16, where expected grade is determined by the year students began 9th grade at LAUSD. Graduated is an indicator set to 1 if a student received a diploma, GED, or special education certificate of completion from LAUSD (mean = 0.50). This similarity is an important feature of the research design that helps bolster internal validity, particularly when comparing longer-run outcomes. The LAUSD administrative data contain individual-level records for all high school students ever enrolled in the district from the Students who were exposed to a police killing within 3 miles of their home either before the 9th grade or after the 12th grade, but not during high school, are not included in this sample. Beck Aaron T., Steer Robert A., Brown Gregory K.. Bertrand Marianne, Duflo Esther, Mullainathan Sendhil. We hope that it will help authors navigate the journal submission process. For example, ninth graders in the 2010â2011 school year. Per Fan and Gijbels (1996), standard errors are calculated using pilot bandwidths equal to 1.5 times the kernel bandwidths. However, students exposed in lower expected grades are significantly less likely to complete high school. Download online appendix. Instead, residence was inferred from the DA incident reports and is a dummy variable set to 1 if the report mentioned that the shooting occurred in or directly outside the deceasedâs home. If the deviations are systematic and persistent, profit-maxi mizing firms should respond to them and tailor their contracts and pricing schemes in response. Notes. The area bore witness to two of the most high-profile acts of police violence in U.S. history. Alternatively, I expand the sample to allow students to appear as both treatment and control in the same expected grade. This process can be quite costly to the district, as students with ED often receive their own classrooms and are sometimes transferred to private schools or residential facilities at the districtâs expense. I searched for each incident by the name of the deceased in six local newspapers (the Los Angeles Times, the Los Angeles Daily News, Pasadena Star News, San Gabriel Valley Tribune, Torrance Daily Breeze, and Whittier Daily News). To account for trends in graduation rates over time, the second difference would capture the between-cohort change in attainment among students who lived farther away from the killing (i.e. Note that text in the Main Menu above or other text in blue are hyperlinks. Similar rankings See other rankings by type of impact factors. Changes in emotional disturbance are also highly persistent with little drop-off several semesters after exposure. Using cross-sectional data, the first difference in a DD model would compare graduation rates of students in expected grades â¤12 living nearby (within 0.50 miles) to graduation rates of nearby students in expected grades >12, where expected grade is determined by the year a student began 9th grade at LAUSD. The reason this may be a concern is that I do not observe whether students who transferred out of LAUSD went on to graduate from other school districts. Transcript data is missing for roughly 5% of students in the school registration data. Goals and Scope. Panel B estimates effects separately for each deceased race subsample. Given the relative frequency of criminal homicides, the opposite is likely true. Following procedures described by Rambachan and Roth (2019), I compare 95% confidence intervals obtained from my primary DD model against those obtained after allowing for per period deviations from a linear trend of up to an arbitrary amount, M. Online Appendix Figure A.IX displays sensitivity plots under 0 ⤠M ⤠0.02 for 0 â¤ Ï â¤ 3, the first four posttreatment periods. Again, I find little evidence of differential pretrends and significant decreases in GPA coinciding with exposure to police killings. For instance, on May 26, 2014, patrol officers attempted to stop Noel Aguilar for riding a bicycle on the sidewalk. Burdick-Will Julia, Ludwig Jens, Raudenbush Stephen W., Sampson Robert J., Sanbonmatsu Lisa, Sharkey Patrick. The pre- and postkilling gradients converge at around 0.50 miles and are roughly parallel from there outward. That is, attendance patterns for students who lived very close to where the event would occur are quite similar to those who lived farther away. QUARTERLY JOURNAL OF ECONOMICS Vol. the IRS since 1927. QUARTERLY JOURNAL OF ECONOMICS ’s. Although this does not rule out the existence of other forms of nonclassical measurement error, the data suggest that intracounty migration is unlikely to be a serious confound. This uptick is largest for those who lived closest to the incident and fades with distance. In total, the data set contains 712,954 unique students. AND STEVEN D. LEVITT In the 1960s Blacks and Whites chose relatively similar first names for their children. Table I, Panel B provides summary statistics for the student data. In the days immediately after a police killing, absenteeism spikes among nearby students. Standard errors are clustered by ZIP code. Nearly 1,000 officer-involved killings occur each year in the United States. This information is used to construct a binary indicator for whether a student was absent for any class on a given day (Whitney and Liu 2017).15. ECONOMICS AND IDENTITY. Leveraging a dynamic difference-in-differences design, I exploit hyperlocal variation in the location and timing of police killings to compare changes in well-being among students who lived very close to a killing to students from the same neighborhood who lived slightly farther away. The processing of your manuscript will begin when the submission fee is received by The Quarterly Review of Economics and Finance. Taken together, my results indicate that police violence may exacerbate racial inequality in education. Column (1) presents my base specification controlling for time trends at the census block group level. A 2015 survey found that 75% of black respondents and over 50% of Hispanic respondents felt police violence against the public is a very or extremely serious issue, while only 20% of whites reported the same (AP-NORC 2015). The benefit of this construction is that it enables me to explicitly test for parallel âpretrendsâ in the cross-sectional data without otherwise having to condition the sample. The primary measures of educational attainment are high school graduation and college enrollment. "A Model of Reference-Dependent Preferences" (with Botond Kőszegi), Quarterly Journal of Economics 1221(4), 1133-1165, November 2006. Whether a nonpolice killing was gang-related was determined from incident descriptions provided by the Los Angeles Times Homicide Database. Column (4) controls for neighborhood-semester effects at the census tract level, as opposed to census block group level (there are roughly 2.6 block groups per tract). By geocoding the exact location of the 627 incidents and over 700,000 home addresses, I can calculate each studentâs precise geographic proximity to police violence. Column (5) instead controls for neighborhood-cohort using arbitrary square mile units derived from dividing Los Angeles into a grid. However, because I am able to account for time trends at the neighborhood level, any potential biases would have to be hyperlocal, differentially affecting students in the same census block group. Table III displays estimated treatment effects from estimation of equation (2) under various specifications. The figure shows DD coefficients and 95% confidence intervals from estimation of equation (1) on an indicator for emotional disturbance (mean = 0.005). To further explore mechanisms, I exploit hand-coded contextual information drawn from district attorney incident reports and other sources. Consistent with a host of survey and ethnographic research showing that a majority of Americans believe that police treat minorities less fairly than whites, I find suggestive evidence that police killings of blacks and Hispanics are more damaging than observably similar killings of whites and Asians (Bayley and Mendelsohn 1969; Brooks 1999; Pew Research Center 2019). The Quarterly Journal of Economics, Volume 135, Issue 4, November 2020, Pages 1799–1848, https://doi.org/10.1093/qje/qjaa015 The remainder of this article is organized as follows: Section II describes the background and data, Section III discusses the identification strategy and provides evidence of its validity, Section IV presents primary estimation results for academic achievement and psychological well-being, Section V explores mechanisms by estimating differential effects by race and incident context and by comparing the effects of police killings to criminal homicides, Section VI examines long-run effects on educational attainment, and Section VII concludes. A similar outbreak occurred in 1992 following the acquittal of Los Angeles Police Department officers involved in the beating of Rodney King, a 26-year-old black man. Researchers have attempted to address this issue by exploiting the timing of high-profile incidents: for example, the police beatings of Rodney King in Los Angeles (Sigelman et al. Download online appendix. Similar shares reported believing that police âdeal more roughly with members of minority groups.â. Advocates of the EITC argue that the credit transfers income to a particularly deserving group of people, the working poor, and that the redistribution occurs with much less distortion of labor supply than is caused by other elements of the welfare system. Figure III displays results from estimating equation (1) on incidence of ED under my preferred specification. 2006). Designing Better Sugary Drink Taxes (with Anna Grummon, Ben Lockwood, and Dmitry Taubinsky) Edwards, Lee, and Esposito (2019) estimate that roughly 1 in 1,000 black men and 1 in 2,000 Hispanic men will be killed by police over their life course, relative to 1 in 3,000 white men and 1 in 7,500 Asian men. Dawson Michael C., Brown Ronald E. L., Jackson James S.. de Chaisemartin Clément, dâHaultfoeuille Xavier. To our knowledge, this is the”rst time that a homogeneous annual series of top wage shares starting before the ... response observable in tax returns was due to income shifting ... 1913–1998. The difference between treatment estimates for unarmed and gun-armed killings is roughly 50% larger than in the full sample and significant at the 5% level in nearly all cases. I find similar results in all cases. The sample contains the pooled cross-section of students living within 3 miles of a killing from expected grades 9 through 16, where expected grade is determined by the year students began 9th grade at LAUSD. (Aug., 1970), pp. Thus, if local crime and student performance are negatively correlated, potential biases would drive treatment estimates for GPA upward (i.e., toward zero). I first explore differential responses by student race. The first is that police killings are quite rare and difficult to predict. Treatment defined as students living within 0.50 miles of a police killing during high school. Control students are those whose nearest killing during high school was between 0.50 and 3 miles away. I find no significant effect on white or Asian students. It is also possible that these differential impacts are driven in part by racial heterogeneity, which I will explore in detail in Section V. Table II, Panel A demonstrates robustness to a host of alternative specifications. Cambridge Journal of Economics : Accepted : 7 : 3 : 1 : My paper was a comment, so I consider this pretty slow. That is, comparing Î²Ï = Î³Ï yields p = .032 at Ï = 0, p = .040 at Ï = 1, and p = .007 at Ï = 2. Student i may appear at multiple expected grades g, but only once per expected grade, with treatment status for observation (i, g) determined by the nearest killing in that grade (i.e., â¤0.50 miles). CXIX August 2004 Issue 3 THE CAUSES AND CONSEQUENCES OF DISTINCTIVELY BLACK NAMES* ROLAND G. FRYER,JR. Alternatively, as I explore in Section VI, affected students may drop out of school entirely, causing treatment estimates to mechanically converge to zero as relative time increases. Editors and Editorial Board Submission Information QJAE Archives Manuscript Preparation: Author Guidelines. This is again consistent with the absenteeism figures and suggests that students living closest to police killings are most detrimentally affected. Median is the median number of articles in each race category, conditional on being mentioned. In this light, the findings suggest that students may be responding to the perceived reasonableness or legitimacy of officer actions as much as to the use of force. QJE is invaluable to professional and academic economists and students around the world. Notably, estimated effects for the original black/Hispanic sample are quite similar to those for the reweighted black/Hispanic sample (â0.031 points versus â0.029 points). Information on whether students enrolled in postsecondary schooling is available for those who graduated from LAUSD between 2009 and 2014 and comes from the National Student Clearinghouse, which provides enrollment information for institutions serving over 98% of all postsecondary students in the country. Similar situations arose when police were confronted by individuals armed with firearms that turned out to be replicas. 10 counts publications from the last 10 years only, 5 the last 5 years: Online Appendix Figure A.X displays results after accounting for staggered treatment timing per Callaway and SantâAnna (2019), and Online Appendix Figure A.XI tests robustness to parallel trends violations per Rambachan and Roth (2019). To test robustness to alternative definitions of neighborhood, column 4 replaces the semester by census block group fixed effects with semester by census tract fixed effects (there are roughly 2.6 block groups per tract). Specifically, I estimate local polynomial regressions of daily absenteeism on the distance between a studentâs home and the incident location. 2014; Gershenson and Tekin 2018) note a strong negative relationship with student test scores. 664 QUARTERLY JOURNAL OF ECONOMICS learning and the resulting choice behavior. The Quarterly Journal of Economics is the oldest professional journal of economics in the English language. Standard errors are clustered by ZIP code. Similarly, all posttreatment estimates for homicides and arrests are insignificant and more than half are negative in sign. GPA declines by 0.04 points in the semester of the shooting and by between 0.07 and 0.08 points in the following two semesters (GPA mean = 2.08, std. Thus, their case studies may not be representative of the vast majority of police killings that go unreported in the media and provide limited insight into the day-to-day effects of use of force on nearby civilians. While the survey is not mandatory, it is typically administered during school hours leading to response rates above 75%. For the sake of power, I pool white and Asian students together. Combined, the results suggest that the marginal impacts of police killings on education are nearly twice as large as those of criminal homicides. = 1). Perhaps the most obvious feature is the dramatic increase in relative citations for articles in The Quarterly Journal of Economics. Cumulative GPA is a studentâs final cumulative GPA on exiting LAUSD (mean = 1.89). 2018) and that cortisol predicts test performance (Heissel et al. Thus, although police killings of blacks and Hispanics exert demonstrably larger effects than killings of whites and Asians, these differences could be driven by factors correlated with race rather than race itself. This procedure ensures nonnegative weights and may better illuminate dynamic treatment effects. Responses are answered along a Likert scale ranging from 1 to 5. I then multiply the average of these estimates (weighted by the share of students in each grade) by the estimated short-run treatment effect (β1). Treatment estimates on graduation in expected grades 9 and 10 are â0.017 and â0.018 points, respectively. 84, No. result if these men make some response. These results are shown in Online Appendix Figure A.II. Thus, the two groups come from similar backgrounds and were probably exposed to similar local conditions, except for the killing itself. In each case, I read and hand-coded reports to capture whether a weapon was recovered from the deceased and, if so, what type. A number of factors may explain the pattern of effects.
