Three Essays In Applied Microeconomics: Philly Style, Alexander Christian Marsella

Graduate Theses, Dissertations, and Problem Reports

My dissertation analyzes several contemporary policy-based and institutional occurrences in an urban setting to help guide further advancements in reducing violence, drug overdose deaths, and other unhealthy behaviors that city governments look to curb. Several recent developments in Philadelphia offer a promising setting for studying policies that have broad implications.

Chapter 1 examines the effect of the West Philadelphia Promise Zone initiative on violent crime rates in a high-crime area of West Philadelphia, where a series of educational, public-safety, and quality-of-life improvement grants were disbursed from 2014 onward. My difference-in-differences analysis with two-way fixed effects and cluster bootstrapped standard errors …

Essays On The Economics Of Law And Crime, Zachary J. Porreca

Graduate Theses, Dissertations, and Problem Reports

The first chapter examines the connection between gentrification and urban violence. I demonstrate a positive and plausibly causal relationship between urban redevelopment and gun violence in Philadelphia. As the underlying mechanism, I focus on gentrification's displacement effect on local drug markets. Treating the city as a spatial network of city blocks and using two-way fixed effects differences-in-differences estimators, I show the gentrification of one block increases violence across the surrounding neighborhood. I find that some 2,400 (8%) of Philadelphia's shootings between the years 2011 and 2020 can be attributed to spillover effects from the gentrification of drug blocks. This effect …

The Effect Of Monitoring And Crowds On Crime And Law Enforcement: A Natural Experiment From European Football, Brad R. Humphreys, Alexander Marsella, Levi Perez

Economics Faculty Working Papers Series

Technological advancements like the presence of smart phones and body cameras have led to increased monitoring of police, but little evidence exists on their impact. We address these problems using data on fouls from football matches in five European football leagues over six seasons. This period contains exogenous changes in monitoring rule enforcers through introduction of Video Assistant Referee review and limited "bystanders" from Covid-19 restrictions. Results from difference-in-differences models estimated separately for each league indicate that both events influenced the number of fouls called with substantial heterogeneity across leagues and home/away teams.

Causal Determinants Of College Success, Benjamin Blemings

Graduate Theses, Dissertations, and Problem Reports

The first essay focuses on alcohol access in college, which is an impediment to many students' success. Alcohol sales to general seating at college football games has been broadly adopted despite results suggesting greater alcohol availability increases crime and college alcohol abuse. Using differences-in-differences, this paper estimates how allowing alcohol sales in college football general seating sections affects crime. Reductions in crime are found after sales are allowed. After sales begin, those under the age of 21 are still not legally permitted to purchase in-stadium alcohol, but are still affected by changes in other stadium policies or law enforcement strategies. …

Property Rights, Consequences Of Electrical Blackouts, And Measures Of Institutional Quality, Kerianne Nicole Lawson

Graduate Theses, Dissertations, and Problem Reports

This dissertation is comprised of three essays. Chapter 1 is about a house titling program, called Khaya Lam, in South Africa. Despite it being legal in South Africa to acquire a title deed to a government-issued home, roughly 20 million South Africans do not hold title to their property. Millions of homes are eligible to have ownership transferred from the government to the individuals living in them, but legal costs and lack of awareness keep these renters from going through the steps to secure title deeds. Though they may occupy the property for years, without a title deed South Africans …

Evaluating Crime As A Negative Externality Of Hosting Mega-Events: Econometric Analysis Of The 2012 London Summer Olympics, Nicholas Le

Economics Faculty Working Papers Series

Analysis of the benefits and the drawbacks of hosting large-scale sporting events like the Olympics or World Cup frequently ignore the effects of crime due to its relatively small economic impact in comparison to employment and consumption effects. Literature has frequently tied sporting events and tourism to crime, in addition to observing proximity effects on crime during sporting events. This research seeks to confirm both by implementing a difference-in-difference regression that can show whether crime increased during the Olympics, in particular in London boroughs which hosted venues for the Games. Ultimately, the research concludes that crime in London as a …

What Is Near And Recent In Crime For A Homeowner? The Cases Of Denver And Seattle, Adam Nowak, Juan Tomas Sayago Gomez

Regional Research Institute Working Papers

This paper analyzes the effects of the concentration of crime on housing prices using nonparametric methods. Specifically, we use a modified local K-function in order to measure crime concentration. This technique provides us with a crime measure that is not dependent on pre-defined boundaries. Results from this analysis suggest a decrease in housing prices of two percent to seven percent for crimes in the past six months that occur within a quarter of a mile of the house.
