I study criminal street gangs using new data that describes the geospatial distribution of gang territory in Chicago and its evolution over a 15-year period. Using an event study design, I show that city blocks entered by gangs experience sharp increases in the number of reported batteries (6%), narcotics violations (18.5%), weapons violations (9.8%), incidents of prostitution (51.9%), and criminal trespassing (19.6%). I also find a sharp reduction in the number of reported robberies (-8%). The findings cannot be explained by pre-existing trends in crime, changes in police surveillance, crime displacement, exposure to public housing demolitions, reporting effects, or demographic trends. Taken together, the evidence suggests that gangs cause small increases in violence in highly localized areas as a result of conflict over illegal markets. I also find evidence that gangs cause reductions in median property values (-$8,436.9) and household income (-$1,866.8). Motivated by these findings, I explore the relationship between the industrial organization of the black market and the supply of criminal activity. I find that gangs that are more internally fractured or operate in more competitive environments tend to generate more crime. This finding is inconsistent with simple, market-based models of criminal behavior, suggesting an important role for behavioral factors and social interactions in the production of gang violence

Gang research has spanned nearly a century. In that time, we have learned that gang membership increases the chances of involvement in homicide as a victim or offender. The violence that embroils gang life, both instrumental and symbolic, often has consequences. In this paper we review the gang homicide literature covering topics such as definitional issues, available data, correlates and characteristics, and theoretical explanations. The review examines individual, group, and structural contexts for gang homicide. We conclude with a discussion of future needs in theory, data, and methods, to improve our understanding of gang homicide.

Gangs impact everyday life and politics across much of the world, yet the literature on gang disengagement—the process whereby people move on from the gang life—is mostly limited to the United States and Europe. In El Salvador, following 30 years of gang wars and a 20-year war on gangs, gang members face severe restrictions from both their gangs and wider society to disengage. Ultimately, this undermines the prospects not only for gang members to remake their lives, but for sustaining reductions in armed violence and addressing a broader set of pressing social issues. Theoretically, I propose a nested, multilevel analysis of gang disengagement, attentive to the interactions between individual, gang-organizational, and social conditions that enable and constrain processes of gang disengagement. Empirically, I employ this framework to scrutinize the evolution of gangs and gang disengagement in El Salvador, and the political solutions necessary for large-scale disengagement moving forward.

In the suffocating heat of summer in El Salvador, José Elvis Herrera Reinoso, alias “Elvis,” is gathered with the family of an elderly woman inside her small home. The woman, who suffers from diabetes, had been close to death just a few days beforehand, but made a seemingly inexplicable recovery. With just a few simple tools, including a Bible and loudspeaker, Elvis guides the family members in a religious celebration of this “miracle.” His well-practiced preaching and passionate reading from the holy book tell anyone listening that he is a dedicated pastor. And the tattoos that cover his face let them know he was a member of the Mara Salvatrucha 13 (MS13), one of the most feared gangs in the world.

Urban armed groups, especially criminal gangs, are a growing threat to peace and economic growth in cities across the world. These groups often exert state-like powers, enforcing contracts, policing, and taxing businesses in the areas they informally govern. The conventional wisdom suggests that criminal organizations provide governance when states do not, and that increasing state services could crowd gangs out.  In partnership with the City of Medellín, researchers randomly introduced a program that intensified government outreach to gang-controlled neighborhoods. The study found no evidence that the city’s intervention reduced gang rule.

Some criminal groups are able to avoid confrontation and diversify their economic activities while others are constantly contested by rival groups and the state. To understand why, we propose a model to investigate criminal groups’ incentives to invest in military capacity and the state’s response to arming. Typically it is difficult to map criminal groups’ presence and document their economic activities. We build a novel panel dataset to map presence and characterize the economic activities of criminal groups in Rio de Janeiro, where drug factions and militia groups have controlled territories for at least three decades. We provide evidence that both groups are multi-product enterprises that explore a wide range of licit and illicit goods and services. We empirically test the predictions of our model. Our findings suggest that more groups in the territory increase conflict and state repression and reduce economic diversification. In addition, we argue that the ability to collaborate with the state is crucial for groups to exploit more markets. To the best of our knowledge, this is the first study that uses systematic data to show how criminal groups in Rio de Janeiro evolve over time and diversify their economic activities.

In this paper, we explore the determinants of co-membership in organised crime groups in a British police force. We find that co-membership of OCGs is higher among individuals who share the same ethnicity and nationality; who have committed acts of violence; and who perpetrate the vast majority of their crimes in the same area. We also find a homophily tendency in relation to age and gender, and that task specialisation within groups is driven by the type of activity. We interpret some results as conforming to the argument that recruitment from a small area and similar ethnic/national background increases cooperation and reduces the likelihood of opportunistic behaviour in a context of rather effective policing. Our findings do not conform to the suggestive image of OC members as ‘urban marauders’ and OCGs as large and powerful multinationals. OCGs tend to be small, localised and formed by people with the same background.

When does organized crime resort to assassinating politicians? In narcocracies, criminal groups co-opt political elites through bribery in exchange for protection to traffic illegal drugs. When criminal groups compete, they may also resort to political violence to influence which candidate wins local elections in strategic areas and retaliate when state action threatens their survival. Using new data on political assassinations in Mexico during 2000–21, we show that political candidates are more likely to be assassinated in areas close to oil pipelines used by drug trafficking organizations for oil theft. Former mayors of areas near oil pipelines remain at high risk of assassination. In municipalities where at least one mayor has already been killed, the arrest of a member of organized crime significantly increases the chance that an incumbent mayor will be killed. Political violence is directed at politicians, not voters, so it has a negligible impact on voter turnout.

Organized crime affects security, development, and democracy worldwide, but not much is known about its social consequences. We study how exposure to the presence of organized crime groups shapes the social capital of Italian citizens, including political participation, civic engagement, and institutional and interpersonal trust. To address this question, we first leverage a survey of almost 800,000 respondents on social capital and exposure to organized crime conducted in Italy between 2000 and 2018. Second, we compile data on social capital and related variables between 1861 and 2020 in the Italian region of Apulia to exploit the unexpected and exogenous arrival, in the 1970s, of organized crime in the region, where no groups had been present before. We compare levels of social capital in Apulia with a synthetic control of regions which were not notably exposed to the presence of organized crime groups. Results from both exercises show that exposure to organized crime reduces political participation, institutional and interpersonal trust and has mixed effects on civic engagement. Using a mediation analysis leveraging both quantitative and qualitative evidence, we show that the negative effects of organized group presence on political participation and trust are largely explained by disinvestment in social capital by those exposed to the presence of criminal groups due to psychological factors (fear and resignation) and frustration with lack of state capacity to deal with the groups.

Regulatory approaches to organised crime aim to minimise exploitation of the legitimate economy by offenders. Unlike criminal justice approaches, regulatory approaches prioritise prevention over enforcement. This study explores the impact of a regulatory approach to organised crime in Queensland which restricted outlaw motorcycle gang (OMCG) members from working in certain industries. We exploit a delay in the implementation of these occupational restrictions after a wider suite of measures commenced, using interrupted time series analysis to analyse changes in organised crime related harm by OMCG members. Results suggest that the introduction of occupational restrictions was followed by a gradual reduction in organised crime related harm by OMCG members (3% to 4% per month). While the reduction is small, it supports the view that regulatory measures are a promising strategy for reducing organised crime.

In this study we explore the enablers of illicit drug trafficking using law enforcement intelligence data on a sample of 587 organised crime groups. We measure the prevalence of other forms of criminal activity and their relationship with poly-drug trafficking, which refers to the trafficking of multiple drug types and is associated with increased profitability, versatility and resilience to disruption. Other forms of criminal activity— including enablers of illicit drug trafficking—were common. Half the groups (52%) were poly-drug traffickers. Groups suspected to have exploited or infiltrated the transport system (air, sea or surface) and those suspected of laundering money via the real estate market or gambling services were more likely to be trafficking multiple drug types. Groups that relied on these enabling activities were more likely to involve professional facilitators. This research highlights a number of key enablers of organised crime that may be targeted to disrupt illicit drug trafficking.

Mob justice is a form of extrajudicial punishment or retribution in which a person suspected of wrongdoing is typically humiliated, beaten, and in many cases killed by vigilantes or a crowd. Mob action takes place in the absence of any form of fair trial in which the accused are given a chance to defend themselves; the mob simply takes the law into its own hands. Mob justice is not only criminal but also amounts to a violation of human rights. Over the past decade, Uganda has seen a significant rise in the number of cases of mob justice. According to the Uganda Police Force’s (2013-2019) annual crime reports, 746 deaths by mob action were reported and investigated in 2019, compared to 426 in 2013, a 75% increase. “Mob kills 42 in 7 weeks,” the Daily Monitor reported in March 2019, citing police figures – an average of six lynchings a week. Homicides by mob action in Uganda occur mainly in response to thefts, robberies, killings, and reports of witchcraft. According to the 2015 Afrobarometer survey in Uganda, one in six Ugandan adults said they took part in mob justice during the preceding year or would do so if they “had the chance.” This suggests that mob justice is not just a fringe problem in Uganda but commands attention and requires collective action. Why would a substantial number of Ugandans resort to taking the law into their own hands as an alternative form of “justice”? Analysts have pointed to a number of factors that might contribute to a willingness to engage in mob justice. One is a lack of trust in the formal criminal justice system to administer fair and timely justice. A 2005 study in Uganda showed that mob actions were often motivated by widespread suspicion or misunderstanding of the justice system, especially concerning the procedure of police bail, under which suspected culprits can be temporarily released before the court process. …Statistical analyses show that a lack of trust in the police is associated with a willingness to engage in mob justice, while perceived corruption undermines trust and thus indirectly contributes to a willingness to join others in mob actions. Further, our analysis finds that being a victim of crime (physical assault), encountering problems in the court system, finding it hard to obtain police assistance, and having to pay a bribe to police or court officials are factors that make people more likely to say they would take part in mob action against suspected criminals.

From Clans to Co-ops explores the social, political, and economic relations that enable the constitution of cooperatives operating on land confiscated from mafiosi in Sicily, a project that the state hails as arguably the greatest symbolic victory over the mafia in Italian history. Rakopoulos’s ethnographic focus is on access to resources, divisions of labor, ideologies of community and food, and the material changes that cooperatives bring to people’s lives in terms of kinship, work and land management. The book contributes to broader debates about cooperativism, how labor might be salvaged from market fundamentalism, and to emergent discourses about the ‘human’ economy.

  This document studies the effect of the homicide rate on internal migration in Mexico. Reduced form evidence shows that net migration of skilled workers decreases into local labor markets where homicide rates increased after 2007, suggesting workers prefer destinations with lower homicide rates. This result is due to lower inflows, without effects on outflows, pointing to the existence of moving costs. To quantify the welfare cost of increasing homicides, we use workers' migration decisions and a spatial equilibrium model. Skilled workers' average willingness to pay to decrease the homicide rate by 1% is estimated at 0.58% of wages. The welfare cost is in the order of several points of GDP per year, depending on the assumptions. Workers who do not migrate bear the largest share of the overall welfare cost

Despite the well-documented human costs of the war on drugs, and the growing evidence of the environmental impacts of illicit economies, the militarized repression of the illicit drug trade remains a central hemispheric security and cooperation strategy in Northern and Central American countries. Through a multi-disciplinary dialogue that combines history, sociology, anthropology, economics, and political science, this Special Issue critically interrogates why despite these failures the war on drug endures. Together, the contributors challenge explanations focused on state absence, weakening of the state, and ungoverned spaces and instead propose a research agenda that sheds light on the long-lasting, structural effects of the capitalistic integration of the region within the economy of illicit drugs. In particular, the Special Issue contributes to three existing and interconnected debates: First: the role of drug economies and illicitness on state formation, social inequalities, and development in Mexico and Central America. Second: the impact of illicit economies on local populations, and the connections between the licit and the illicit, margins and centers, and political orders and violence. Third: the variety of stakeholders that benefit from the war on drugs and that link the United States, Mexico, and Central America in licit and illicit fashions.

While most Americans have focused on the Covid-19 pandemic, the nation’s other great epidemic has continued to burn. Drug overdoses now claim the lives of over 100,000 Americans every year, a rate that appears likely to continue or grow for the foreseeable future. While the crisis once was concentrated predominantly in rural, white communities, the introduction of novel synthetic opioids, particularly fentanyl, into the illicit drug supply has spread overdoses across urbanizations. Today, small-town and big-city leaders alike desperately need tools to fight back against the drug crisis. It can often seem as though drug policy is outside the ambit of local leaders, who lack the capacity to go after international traffickers or spend trillions of dollars on care. But local government, as the closest entity to the front lines of the crisis, plays a vital role in addressing it. This paper, therefore, explores options for local policymakers to respond to the drug crisis. In particular, it considers six frequently discussed local-scale policies: • Naloxone access and distribution • Investing in treatment capacity • Drug court programs • Wastewater tracking • Supervised consumption sites • Drug market interventions For each policy, this paper examines the evidence, offers estimates of costs, and provides caution where necessary. The overall goal is to give local policymakers a better understanding of what tools they have to more effectively tackle the other health crisis in their communities.

  According to the United Nations Office on Drugs and Crime (UNODC), the Americas is the most violent region in the world. The Americas has a homicide rate of 16.3 per 100,000 people, while Africa had a homicide rate of 12.5 per 100,000 inhabitants. Europe, Oceania, and Asia had much lower homicide rates with three percent, three percent, and 2.9 percent, respectively (see Fig.  1.1).1 The Americas is also home to the most violent country in the world. In 2015, El Salvador surpassed Honduras as the most violent non-waring nation. Violence has exceeded the days of the country’s civil war, which lasted for more than a decade. In fact, experts note that at one point in 2015 El Salvador had one murder per hour. Jonathan Watts writes, “Last Sunday was, briefly, the bloodiest day yet with 40 murders. But the record was beaten on Monday with 42 deaths, and surpassed again on Tuesday with 43. Even Iraq—with its civil war, suicide bombings, mortar attacks and US drone strikes—could not match such a lethal start to the week.”2 In January 2017, the country saw a rare phenomenon occur: one day without a murder.3 Much of the violence in El Salvador has been a result of gang-related activities as well as the consequences of the government’s tough on crime strategies.4 El Salvador’s neighbors, Guatemala and Honduras, have also seen high levels of gang-related violence.5 Honduran President Juan Orlando Hernández argued that 80 percent of the homicides that occur in this country are related to organized crime.

Outlaw motorcycle gangs (OMGs) have received increased attention from both law enforcement agencies and the research community. This study investigates the criminal collaboration patterns of two OMGs with a long history of hostilities. We use government data on individuals registered as belonging to Hells Angels MC, Bandidos MC and individuals with multiple OMG memberships, and suspicion data from 2011 to 2016 to build co-offending networks. Our results show that members of multiple OMGs tend to have higher centrality and clustering. These members also have the highest levels of suspicions per capita, and most of the co-offending is related to nexus links involving multiple membership individuals. They can be described as ‘criminal nomads’, collaborating with individuals from different organisations. Our results suggest that core members tend to engage in white-collar crime to a greater extent than those on the periphery, which tend to engage more in violence and drug crime.

Drawing upon research undertaken by the present author in East, North West and South London and the work of other UK social scientists, this article considers the evidence concerning the involvement of young people of African-Caribbean origin and Mixed Heritage in street gangs and gang crime in London (For the sake of brevity, I will simply refer to these young people as Black, not least because this is how they usually define themselves). It outlines the sometimes acrimonious debate about the relationship between race, crime and street gangs in the United Kingdom in the past three decades, concluding that while many of the claims made about this relationship may be exaggerated or simply untrue, the evidence for the over-representation of Black young people in street gangs in London is compelling. The article then turns to the changing social and economic predicament of some Black young people in the capital since the 1980s and its relationship with their involvement in gang crime. Finally, it considers the role of drugs business in the proliferation of the gang form and ‘gangsta’ culture and the involvement of growing numbers of younger Black people in County Lines drug dealing.

  Corruption, which can be defined as the 'abuse of entrusted power for private gain', poses a significant threat in the European Union. Corrupt practices can lead to a misuse of public funds and can contribute towards an erosion of democracy and the rule of law. The European Union can do more to tackle corruption and curb its negative impacts on society. This report draws on a quantitative analysis of corruption in the EU with a focus on three aspects: i) democracy and the rule of law; ii) public trust in institutions; and iii) public procurement. Further EU action to tackle corruption could strengthen trust in public institutions and enhance regulatory certainty. In quantitative terms, the social and economic gains could reach up to €58.5 billion per year.
