n recent decades, the global debate on gun control has been prominent, with many countries adopting more restrictive policies. Brazil followed this trend by implementing stringent measures in 2003; however, the presidency of Jair Bolsonaro in 2019 introduced normative changes aimed at facilitating...

In the span of ten days, the United States experienced two of the deadliest mass shootings in American history. The first mass shooting at a grocery store in Buffalo, New York killed ten people and injured three more—mostly elderly shoppers. The second mass shooting at an elementary school in...

Toy guns are subject to federal product safety regulation. Real guns are not. If a defect in an air rifle causes it to discharge without warning, the manufacturer would be required to promptly notify a safety regulator (the Consumer Product Safety Commission); to recall the air rifle; and to...

Researchers specializing in gun policy often measure the effect of a given policy using a standard difference-in-difference approach. We highlight a potential concern with this method which complicates the identification of a causal relationship: gun access potentially changes with legislation....

Gun violence is a major problem in the United States, and extensive prior work has shown that higher temperatures increase violent behavior. In this paper, we consider whether restricting the concealed carry of firearms mitigates or exacerbates the effect of temperature on violence. We use two...

Overconfidence leads to risky behavior, including when people are around guns. Does overconfidence also shape attitudes about gun ownership and use? We evaluate this possibility by conducting nationally representative surveys in six countries in the Americas, including the United States. Results...

Objective: This paper considers the influence of female legislators on gun legislation across US states. Females have behavioral differences from males and likely different exposure to gun-related violence. Method: Using data from 1991-2020, we econometrically estimate the drivers of gun...

This paper studies the effect of police-involved shootings on gun violence and civilian cooperation with police, as proxied by crime reports made via 911 calls. To distinguish between crime reporting and crime incidence, we use administrative data on 911 calls and ShotSpotter data from...

Using Measure 114's narrow passage in Oregon as a natural experiment, we study how new gun regulations affect firearm demand. Background checks, a proxy for demand, rose 13.9% in anticipation of the referendum and surged 157% immediately following the election. After judicial intervention halted...

This paper estimates consumer demand for firearms with the aim of evaluating the likely impacts of firearm regulations. We first conduct a stated-choice-based conjoint analysis and estimate an individual-level demand model for firearms. We validate our estimates using aggregate moments from...

Scholars document that attitudes toward guns and gun policy reflect deeply entrenched cultures that overlap with ideological affiliations and party politics. Does exposure to dramatic events such as school shootings and protests regarding gun control affect these patterns? I first argue that...

One of the most controversial elements of research in gun violence is the debate surrounding which proxy for gun prevalence best captures the true variation in gun availability. We test the effectiveness of several common gun prevalence proxy variables against what is arguably the best measure...

This paper estimates consumer demand for firearms with the aim of evaluating the likely impacts of firearm regulations. We first conduct a stated-choice-based conjoint analysis and estimate an individual-level demand model for firearms. We validate our estimates using aggregate moments from...

An estimated quarter- to half-million guns are smuggled from the U.S. into Mexico each year. Seventy percent of guns recovered at Mexican crime scenes are traced back to the U.S. Many of these weapons are military-styled assault rifles, shipped into Mexico by U.S. drug gangs. This pipeline...

As the Supreme Court sits ready to curtail both abortion rights and gun control laws in its current term, this Note seeks to retheorize the nexus between the constitutional claims to abortion and individual gun ownership. It departs from existing theories, which largely frame the legal arguments...

Using linked individual data on concealed handgun permits (CHP), reported crimes and arrests, I examine the dynamics of gun-ownership, victimization and neighborhood crime. I initially show that new CHP holders are 68% more likely to be crime victims with the largest increase due to having a...

This paper shows that shootings are predictable enough to be preventable. Using arrest and victimization records for almost 644,000 people from the Chicago Police Department, we train a machine learning model to predict the risk of being shot in the next 18 months. We address central concerns...

We analyze a sample of 47 major US cities to illuminate the mechanisms that lead Right-to-Carry concealed handgun laws to increase crime. The altered behavior of permit holders, career criminals, and the police combine to generate 29 and 32 percent increases in firearm violent crime and firearm...

This paper studies the language used in television news broadcasts to describe police killings in the United States from 2013-19. We begin by documenting that the media is significantly more likely to use several language structures - e.g., passive voice, nominalization, intransitive verbs -...

We examine the impact of school shootings on health and human capital outcomes of exposed students as adults in their twenties and early thirties. Our data on school shooting incidents is from a database compiled by the Center for Homeland Defense and Security. The analytic dataset contains...

Gun shows are public gatherings where licensed gun dealers and private gun owners use formal and informal venues to exchange information or sell and buy firearms, accessories, and ammunition. A major challenge is that gun shows, unlike established business locations, can be considered gray zones...

We develop a theoretical model to explain both the high level and persistence in gun violence for black males ages 15-24 consistent with the empirical literature. A person may carry a gun for instrumental (i.e., criminal) reasons or for its perceived protective benefit. Discerning underlying...

Can gun violence be deterred at low cost? We report the results of a randomized experiment of a messaging intervention which was designed to reduce gun violence among individuals under parole supervision with a prior violent felony conviction or firearm arrest. The intervention consisted of a...

We study the opposing deterrent and enabling effects of guns carried by law-abiding citizens on violent crime, using the location of shooting ranges as an instrument. Our incident-level data based on admittedly imperfect data from the Gun Violence Archive suggests that defensive gun use (DGU) by...

We explore the relationship between gun prevalence and homicides in the United States from 2003-2019. Unlike previous research, which typically uses an indirect, state-level measure of gun prevalence, we use a direct measure of guns in a narrow geographic area: gun dealers. We find an increase...
