New Ideas for Addressing and Measuring Mexican Cartel Activity
In Mexico, violence and corruption, and their connections to illegal drugs in the United States, are a significant concern. While measuring corruption is notoriously difficult, a study in Science estimated how many people are employed by and flow in and out of Mexican criminal organizations (cartels) responsible for much of the violence and corruption. The study created a model to analyze the policy implications of such information.
In an accompanying article in Science, researchers at Carnegie Mellon University (CMU), the University of Maryland College Park, and the RAND Corporation critically evaluate that study’s contributions and also propose ideas for advancing research on this important topic.
“Their study provides the first systematic estimates of individual cartel sizes and total employment,” notes Jonathan P. Caulkins, professor of operations research and public policy at CMU’s Heinz College, who led the article. “The model is an important contribution because there have been few serious attempts to capture what drives cartels’ size or violence.”
Caulkins and co-authors note that having a sense of scale gives a useful sense of perspective. For example, dividing the annual number of deaths and disappearances of cartel staff (about 6,500) by the estimate of the number who active at any one time (about 175,000) suggests that cartel staff’s annual death risk is about 1.5 times the death risk for U.S. service members serving in World War II (overall, not just per year). That underscores just how pervasive violence is in the criminal organizations.
“The study assembled a variety of data that was accessible but scattered and integrated those data through a stocks and flow model,” explains Beau Kilmer, senior policy researcher at RAND, who coauthored the article. “This type of model is common across may scientific disciplines but rare in studies of crime and drug policy.”
In their response, the Caulkins and colleagues analyze the study’s use of this model and discuss its applicability to conditions today. Among the challenges identified, they note that counting the stock of cartel employees is a nuanced task given differences between full-time workers and gig workers.
The authors also suggest that given the figures cited in the study, the risk of incarceration may not be the primary cost to be traded off against the benefits of criminal income, camaraderie, and other advantages of cartel membership. The authors offer three suggestions for work on this topic, including research that:
- Articulates which principles drive cartel staffing and behavior: Among the questions to address are why cartels’ staffing levels have been growing when drug market trends (e.g., the legalization of cannabis in the United States) might suggest the need for smaller staffs, and whether the size of cartel staff drives violence or vice versa.
- Improves understanding of drug consumption and prices on both sides of the border: Amid severe deficiencies in relevant data systems, the U.S. government should do more to support analyses of illegal drug markets, especially prices and purity across different market levels, to yield information about U.S. drug consumption and the resulting net revenues for drug trafficking organizations at each market level.
- Expands the scope beyond the murders of cartel members: Adopting a broader vision of how cartels harm social welfare to include violence against journalists, politicians, and law enforcement may widen the policy options available to address the problems.
The writing of the article was funded by the National Science Foundation.
