Organised Crime

This VoxDevLit reviews research on the roots and development impacts of organised crime. Weak state capacity, dense local social networks, and incentives from illicit markets enable the rise and expansion of criminal organisations. These groups exert territorial control, engage in extortion, recruit children and, in some cases, establish forms of criminal governance and political influence. Their presence has persistent negative effects on economic growth, labour market outcomes, and human capital, while also undermining social trust through violence, corruption, and parallel authority structures. We examine policy responses – including policing reforms, prison rehabilitation, and preventive interventions such as conditional cash transfers, school-based programs to shift norms or raise labour market expectations, and cognitive behavioural therapy. We highlight that these approaches can show greater effectiveness in reducing violence and recruitment when implemented alongside stronger formal institutions.

Organised Crime: Policy Summary

Organised crime is not a marginal security issue – it is a core development challenge. Where criminal groups gain a foothold, they throttle local growth, discourage private investment, erode human capital and public health, and hollow‑out citizen trust in the state. Evidence surveyed in this VoxDevLit shows that homicide rates, school dropout, and forced displacement all rise in territories where mafias, cartels or gangs exert control, while property values, firm creation and formal employment fall. These social costs cumulate: in Italy, long‑run GDP per capita is an estimated 16% lower in municipalities infiltrated by the mafia, and Salvadoran neighbourhoods subject to gang ‘taxation’ pay higher prices for basic goods and suffer worse labour‑market outcomes.

Why do criminal organisations thrive?

1. Weak but present states. Criminal governance emerges where formal institutions police selectively, adjudicate slowly, or tolerate corruption; it rarely appears in true vacuums.
2. Lucrative illicit markets and low legal returns. High profits from drugs, extortion or people smuggling, coupled with limited formal jobs, pull labour and capital into crime.
3. Social embeddedness. Dense neighbourhood or prison networks give gangs the cohesion to enforce rules, settle disputes and recruit youths.
4. Unintended policy spillovers. Mass deportations, indiscriminate crack‑downs and overcrowded prisons have exported criminal ‘know‑how’, fragmented cartels and spread violence rather than containing it.

What works and what backfires

Heavy‑handed, untargeted crack‑downs (‘kingpin’ arrests, militarised sweeps) often splinter hierarchies, ignite turf wars and undermine local legitimacy, even when headline arrests climb. By contrast, focused deterrence and intelligence‑led policing that concentrate sanctions on the most violent actors while offering off‑ramps for those who desist have reduced shootings in multiple high‑crime cities. Similarly, judicial integrity measures – such as the temporary dismissal of mafia‑captured Italian city councils – have spurred employment, entrepreneurship and property values without triggering reprisals. On the preventive side, conditional cash transfers, unemployment insurance and credible job programmes raise the opportunity cost of crime and cut recruitment, but they must reach adolescents before gangs do. School‑based police patrols in El Salvador, for instance, reduced teenage recruitment and later incarceration by targeting the exact times and places where gangs scout for new members. Interventions that build socio‑emotional skills – cognitive‑behavioural therapy, after‑school tutoring, mentorship – further lower violent behaviour and long‑term offending. Prisons are pivotal. When overcrowded and ungoverned they become command‑and‑control hubs; when securely managed and paired with rehabilitation, they disrupt criminal networks and lower recidivism. Isolating high‑level bosses, reducing overcrowding, and providing market‑relevant training turn prisons from crime incubators into sites of desistance.

Policy principles for lasting impact

1. Pair smart enforcement with opportunity expansion. Raise the expected cost of crime and the expected return to legality; one without the other rarely suffices.
2. Start early. Resources aimed at 12‑ to 17‑year‑olds – when recruitment peaks – likely yield the highest marginal returns.
3. Treat extortion like violence. Criminal taxation saps growth and disproportionately harms the poor; metrics and enforcement should target it explicitly.
4. Strengthen institutions, not just operations. Transparent procurement, merit‑based policing, and timely courts undercut the corruption on which organised crime depends.
5. Make prisons part of the solution. Secure management plus rehabilitation prevents the cycle of prison‑based recruitment and community spillovers.
6. Measure what matters. Track recruitment, extortion payments and mobility restrictions – not only homicide – to capture the full welfare gains of policy.
