What Doesn’T Kill You Makes You Stronger: The Shifting Strategies Of Japan’S Yakuza In Response To Economic Globalization And Securitization, Benjamin P. Murkison

Honors College Theses

The Yakuza in Japan is a deeply traditional and infamous ethnic mafia, which has historically based their profits off of the protection of gambling rings and street vendors, but have developed into one of the most sophisticated and wealthy criminal institutions in the world. Reaching their peak in the 1960’s with around 200,000 members, the Yakuza has been in a slow decline ever since. However, the past decade has seen the most dramatic drop in Yakuza numbers in recorded history, as a result of increasing securitization by the Japanese state. As their power has declined within Japan, they have only …

Guns And Fatal Police Shootings: Accuracy Of Firearm Prevalence Proxies In A Panel Data Analysis, Corin Elmore

CMC Senior Theses

This paper explores the relationship between gun prevalence and fatal police shootings in the United States. Specifically, the study assesses the validity of using FSS (Firearm Suicides Per Total Suicides) as a proxy for gun prevalence. It examines whether FBI background check data can be a more reliable alternative. Through a panel data analysis, the study provides moderate evidence that FBI background check data performs better than FSS as a proxy for gun prevalence and that the relationship between firearm prevalence and fatal police shootings is positive. Additionally, the study finds that instrumenting FSS with background check data to account …

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

Graduate Theses, Dissertations, and Problem Reports

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 …

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 …
