In the past decade, police departments have increasingly adopted predictive policing programs in an effort to identify where crimes will occur and who will commit them. Yet, there have been few empirical analyses to date examining the efficacy of such initiatives in preventing crime. Using police and court data from the second-largest police department in the country, this paper seeks to evaluate the pilot version of Chicago’s Strategic Subject List, a person-based predictive policing program. Using a boundary discontinuity design, I find that individuals eligible for the Strategic Subject List were 2.07 times more likely to be found not guilty of all charges in court than similarly situated individuals in the control group. Taking into account crime category heterogeneity, I find evidence that individuals previously arrested for drug crimes drive this result. This research sheds light on the potential unintended consequences of person-based predictive policing.

Does Media Coverage of Sexual Assault Cases Cause Victims to Go to the Police? Evidence from FBI Data and Google Trends
By Harry Elworthy
This paper investigates the effect that national news coverage of prominent sexual assaults has on the reporting decisions of sexual assault victims. Estimates are based on time series data of reports made to police stations in the US from 2008 to 2016 and Google Trends data of search volume, along with an identification strategy that uses a number of individual high profile sexual assault allegations and related events as instruments. By removing assaults that occurred on the day that they were reported, I estimate the effect of coverage only on the reporting of assaults, and not on assaults themselves. A significant positive effect of news coverage on sexual assault reporting is found using several specifications. Back-of-the-envelope calculations suggest that there were between 31 and 121 additional reports of sexual assault for each of the 38 high profile events captured. No evidence is found to suggest that these additional reports of sexual assault have different arrest rates to other reports, indicating that there are not a significant number of false reports. This paper adds to current literature on the sexual assault reporting decision by considering the effect of news coverage and by using different methods of inference to previous papers.

The Impact of Access to Public Transportation on Residential Property Value: A Comparative Analysis of American Cities
By Moses Snow Wayne
This paper develops a consistent model for analyzing the impact of access to public transportation on property value applied to the four cities of Atlanta, Boston, New York, and San Francisco. This study finds a negative relationship between increasing distance to public transit and property value. Additionally, the elicited effects in each city generally align with geographic features and the degree to which a city is monocentric. This study also demonstrates the salience of using actual map-generated distances as proximity measures and characteristics of public
transit systems in modeling the relationship between public transportation and residential property value.

The Great Migration caused massive demographic changes in Northeastern and Midwestern cities as African Americans moved from the South to the North. These changes led to economic discrimination and segregation within northern cities. This paper compares African American and white rental prices in four major cities: Chicago, Detroit, New York City, and Philadelphia in an effort to see how this discrimination and segregation affected rental prices. The results consistently show that in the most precise geographic area, prices rise as the concentration of blacks in those neighborhoods rise, which I believe is a result of overcrowding.
