This article provides an economic analysis of underground gun markets, drawing on interviews with gang members, gun dealers, professional thieves, prostitutes, police, public school security guards and teenagers in the city of Chicago, complemented by results from government surveys of recent arrestees in 22 cities, plus administrative data for suicides, homicides, robberies, arrests and confiscated crime guns. We find evidence that transactions costs are considerable in the underground gun market in Chicago, and to some extent in other cities as well. The most likely explanation is that the underground gun market is both illegal and ‘thin’– relevant information about trading opportunities is scarce due to illegality, which makes search costly for market participants and leads to a market thickness effect on transaction costs.

Gun Markets
The systematic study of how available weapons influence the rates, patterns, and outcomes of criminal violence is new, but it is now a well-established and fast-growing subfield in criminology, legal studies, public health, and economics. This review focuses on the transactions that arm dangerous offenders, noting that if those transactions could be effectively curtailed it would have an immediate and profound effect on gun violence and homicide rates. Guns are legal commodities, but violent offenders typically obtain their guns by illegal means. Our knowledge of these transactions comes primarily from trace data on guns recovered by the police and from occasional surveys of gun-involved offenders. Because most guns used in crime are sourced from the stock of guns in private hands (rather than a purchase from a licensed dealer), the local prevalence of gun ownership appears to influence the transaction costs and the proportions of robberies and assaults committed with guns rather than knives or other weapons. Nonetheless, regulations that govern licensed dealers have been linked to trafficking patterns and in some cases to the use of guns in crime.
New US Surgeon General Advisory on Gun Violence
Deaths from firearms have soared in the US over the past few decades. Now, guns are the leading cause of death of children. In addition, the majority of adults report they’ve experienced gun violence, including being threatened by a firearm or witnessing someone getting shot.
US Surgeon General Declares Firearm Violence a Public Health Crisis
This Medical News article is an interview with US Surgeon General Vivek Murthy, MD, MBA, and JAMA Editor in Chief Kirsten Bibbins-Domingo, PhD, MD, MAS, about a new advisory that declares gun violence a public health crisis.
Investigating the Link Between Gun Possession and Gun Assault
Among a long list of issues facing the American public, guns are third only to gay marriage and abortion in terms of people who report that they are ‘‘not willing to listen to the other side.’’
In concert with this cultural rift, scholarly discussion over guns has been similarly contentious. Although scholars and the public agree that the roughly 100000 shootings each year in the United States are a clear threat to health, uncertainty remains as to whether civilians armed with guns are, on average, protecting or endangering themselves from such shootings. Several case–control studies have explored the relationship between homicide and having a gun in the home, purchasing a gun, or owning a gun. These prior studies were not designed to determine the risk or protection that possession of a gun might create for an individual at the time of a shooting and have only considered fatal outcomes. This led a recent National Research Council committee to conclude that, although the observed associations in these case–control studies may be of interest, they do little to reveal the impact of guns on homicide or the utility of guns for self-defense. However, the recent National Research Council committee also concluded that additional individual-level studies of the association between gun ownership and violence were the
most important priority for the future. With this in mind, we conducted a population-based
case–control study in Philadelphia, Pennsylvania, to investigate the relationship between being
injured with a gun in an assault and an individual’s possession of a gun at the time. We included
both fatal and nonfatal outcomes and accounted for a variety of individual and situational confounders also measured at the time of assault.
Can Mass Shootings be Stopped?
The mass shooting at Columbine High School in Littleton, Colorado, happened nearly two decades ago, yet it remains etched in the national consciousness. Columbine spurred a national debate — from personal safety to the security of schools, workplaces, and other locations and to broader considerations of guns and mental illness. To this day, communities still are grappling to find solutions to the complex and multifaceted nature of mass shootings.
Assault Weapons, Mass Shootings, and Options for Lawmakers
What Are the Most Effective Policies in Reducing Gun Homicides?
The public mass shootings in Newtown, Charleston, Orlando, Las Vegas, Sutherland Springs, Pittsburgh, and, especially, Parkland have brought the issue of firearm violence to the forefront. These tragedies have sparked a national debate about federal and state policies to reduce firearm violence. State policymakers are grappling to identify solutions by considering multiple legislative proposals, from red flag laws to universal background checks to bans on assault weapons to stricter regulation of semiautomatic weapons. Some states are considering laws that make it easier to carry and use firearms in public. Still others are debating laws aimed at eradicating gun culture, by — for example — banning all gun-related activities (such as shooting clubs or trainings) at public high schools. With a myriad of often conflicting ideas and proposals, where does a state policymaker begin?
This policy brief will help state policymakers navigate the scientific evidence regarding the impact of state firearm laws on gun-related homicide. Taking advantage of new data resulting from a research project at the Boston University School of Public Health and with funding from the Robert Wood Johnson Foundation’s Evidence for Action Program,[1] we developed a comprehensive database of state firearm laws spanning the period 1991-2016. We then examined the impact of a range of state firearm laws on total, firearm-related, and nonfirearm-related homicide rates at the state level during this time period. The State Firearm Laws Database is publicly available at www.statefirearmlaws.org.
Our analysis found three priority pieces of legislation that would have the greatest impact in reducing overall firearm homicide rates:
Universal background checks.
+ Prohibition of gun possession by people with a history of any violent misdemeanor, threatened violence, serious alcohol-related crime, or subject to a domestic violence restraining order. This must be accompanied by: (1) a requirement that firearms already in their possession be surrendered; (2) a procedure for confiscating guns if they are not relinquished voluntarily; and (3) procedures for confiscating guns in situations where a person becomes prohibited from owning firearms after having passed an earlier background check.
+ Laws that give discretion to law enforcement officials (“may issue” laws) in denying concealed carry permits to those who are at high risk for violence, especially those who have a criminal history of violence.
The purpose of this research was not simply to identify a list of laws that “work” and laws that “do not work.” The advantage of this research is that it allowed us to compare the impact of multiple laws at the same time, enabling us to obtain a sense of what laws appear to be most strongly associated with lower rates of firearm homicide. Ultimately, our goal was to identify the types of laws that appear to have the greatest impact and which should therefore be a priority for policymakers.
Deconstructing Mass Shootings: Exploring Opportunities for Intervention
When it comes to mass shootings, the United States is tragically in a class of its own. There are more mass public shootings in the US than in any other country in the world (Lankford, 2016). By some estimates the United States has experienced 318 mass public shootings between 1966 and 2017 (Capellan, Johnson, Porter, & Martin, 2019). These attacks resulted in 1,167 dead and 1,777 injured victims. Unfortunately, mass public shootings show no signs of slowing down. Most research indicates that the rate of mass public shootings has been accelerating over time. For example, Joel Capellan finds that in the 1970s a mass shooting occurred, on average, every 608 days. By the current decade, a mass public shooting occurred, on average, every 20 days. Due to their reoccurring and devastating nature, mass public shootings are starting to be considered a major public health hazard.
Research on mass public shootings has focused almost exclusively on either the characteristics of offenders or the causes leading to these massacres. Although this research is invaluable to our theoretical understanding of the sociological and psychological factors that lead to mass public shootings, it has yet to provide an actionable understanding of how to prevent or mitigate the lethality of these massacres. In this policy report, we argue that prevention requires us to refocus our attention from why to how mass public shootings happen. To this end, we deconstruct mass public shootings into a series of stages and decisions and explore various opportunities for intervention. We analyze the motivations, preparatory behaviors, execution, and conclusion of 318 mass public shootings in the United States between 1966 and 2017. Furthermore, we offer some potential policy solutions to exploit these opportunities for intervention.
Unfinished Business: Gun Violence on the Policy Agenda
Gun violence mortality is 27 percent higher than a decade ago, and, due to a lack of federal action, states have taken the reins in combating this crisis through significant policymaking. However, there is not much research on the progress or process of enacting important laws on gun violence, including identifying the types of bills introduced, how they proceed through the legislative system to enactment, and how year-to-year changes in political leadership affect that process. To better understand recent state policymaking in New York, the Rockefeller Institute of Government’s researchers analyzed the 161 firearm-related bills introduced by the governor, Senate, and Assembly in New York between 2018 and 2019 to identify trends in legislative interest and activity.
