Roadmap: The internal organization of criminal groups

  • Last time: how criminal groups are structured and why it’s hard
    • Network properties: size, centralization, compartmentalization
    • Organizational problems: collective action, free-riding, principal-agent
    • Mechanisms: violence, trust, codes of conduct
    • Any questions from Monday?
  • Today: empirical cases that put the theories to work
    • A Chicago drug gang (Levitt & Venkatesh 2000)
    • Pirates!
  • Also: quiz at the end of lecture, 10:25 a.m.

Case 1: A Chicago drug gang

Studying organized crime from the inside

  • Sudhir Venkatesh, sociologist
  • Arrived at a Chicago housing project with a clipboard and survey
  • A gang leader laughed at his questions and held him overnight
    • …but this began a years-long relationship
  • Eventually, he gained access to gang’s internal financial records

  • Most research on OC relies on secondhand or removed sources
    • E.g., court or police data, interviews with former members
    • What you can study shapes what you can know!
  • Ethnography: immersive, long-term fieldwork
    • The researcher participates in or closely observes daily life
    • …to try and understand a social world from within

The gang’s franchise structure

  • A central organization (“the board”) sits at the top
    • Owns the “brand,” controls territory, sets rules
    • Local gangs pay a fee to operate under the gang’s name
  • Like a McDonald’s franchisee: use the name, follow the rules, pay a cut upward
  • …but retain substantial day-to-day autonomy

Think-pair-share: the franchise structure

Recall the properties of criminal networks from Monday:

Dimension Less More Core tradeoff
Size Small Large Secrecy vs. capacity
Centralization Decentralized Centralized Resilience vs. control
Compartmentalization Low High Efficiency vs. security
  • Where does this gang fall on each dimension? What are the pros and cons of those choices?
  • What does this organizational structure tell you about the environment the gang operates in?
  • Where do you see the principal-agent problem in the franchise structure?
  • How does the franchise model help and/or hurt with collective action?
  • The rival gang used a different approach
    • Leader is a supplier: low-level members buy drugs upfront with their own money, then resell
    • What difference might that or did that make?

Revenues and costs

The gang’s finances look surprisingly like a small business operating on thin margins

Revenues Monthly avg.
Drug sales $54,400
Dues from members $12,600
Extortion of local businesses $5,200
Total revenues $72,200
Costs Monthly avg.
Wholesale drugs $11,800
Tribute to gang hierarchy $9,200
Mercenary fighters $2,200
Funerals/payments to families $1,200
Weapons $1,400
Miscellaneous $3,400
Wages: officers $5,200
Wages: foot soldiers $22,800
Total costs $57,400

All figures converted to approximate 2025 dollars

Does anything surprise you from these tables?

  • Net profit to local leader: ≈$14,800/month; foot soldier wage: ≈$500/month
  • The local leader does well; foot soldiers barely clear minimum wage

The wage puzzle

  • Foot soldiers earn approximately $6.60 per hour
    • This is below the federal minimum wage ($7.25)
    • During gang wars, members may be paid higher wages to help compensate risk
    • …But, annual mortality risk is high (for a foot soldier: roughly 1 in 4 over four years)
    • Why join? Rational choice? Psychology? Social networks? Structure?
  • One answer: foot soldiers are not paid for today’s work, they are competing for a “prize”
    • Tournament theory: in hierarchies, high wages at the top are not just compensation
    • They are the prize that motivates everyone below to compete
  • Criminal application:
    • Foot soldier today \(\rightarrow\) officer tomorrow \(\rightarrow\) local leader eventually
    • The “lottery” logic: most people lose, but the prize is large enough to motivate entry
    • Policy implication: if tournament logic drives entry, what would actually deter it?

Violence, the absence of law, and agency costs

  • Gang wars are costly: profits go negative during fighting; drug demand falls 20–30%
  • Yet the gang fights roughly one-quarter of the time. Why?
  • No contracts → violence as dispute resolution
    • Gangs have no access to courts, property rights, or enforceable agreements
    • Territorial disputes cannot be settled legally \(\rightarrow\) fighting may be the only option
  • Principal-agent problems within the gang
    • Foot soldiers benefit personally from building a reputation for toughness
      • …but unsanctioned violence triggers retaliation that is costly for the whole gang
    • Leaders cannot perfectly monitor or restrain foot soldiers
      • \(\rightarrow\) Individual incentives produce collectively worse outcomes

Case 2: Caribbean Pirates

The hook: do pirates count as organized crime?

  • Varese: OC attempts to regulate/control the production/distribution of a market unlawfully
    • Do pirates fall into this definition?
  • An alternative definition:
    • Any long-term arrangement between criminals requiring coordination
    • …whose agreements cannot be enforced by the state
  • But here is why pirates are worth studying:
    1. Pirates faced the exact same organizational problems:
      • Collective action problem
      • Free-rider problem
      • Principal-agent problem
    2. We can study why people became pirates through the frameworks we discussed in L4
    3. Yo-ho-ho!

Were merchant ships more disorderly than pirate ships?

  • Pirate crews were large: hundreds of men living together at sea for months
    • Yet cooperation was surprisingly orderly, compared to law-abiding contemporaries
    • No courts, no contracts, or lawyers… and yet it worked arrgh-uably pretty well
  • For contrast: how did legal merchant ships solve their organizational problems?
    • Rich owners did not want to live life at sea, so they hired captains to monitor crews
    • \(\rightarrow\) Classic principal-agent problem
    • \(\rightarrow\) Owners granted captains full authority: corporal punishment, control of rations and pay
  • But autocracy created a new problem: captain predation
    • Captains could cut rations, withhold pay, abuse crew members
    • Sailors had little legal recourse once at sea
    • But any rebellion against the captain would be punished by the state once back at land

The pirate solution: democracy on the high seas

  • Pirates owned their own ships: the crew were the owners
    • \(\rightarrow\) The PA problem is reversed: how do you constrain the captain, not the crew?
  • Separation of powers:
    • Captain elected for battle only; quartermaster controls loot distribution and discipline
    • \(\rightarrow\) No single person controls both violence and resources
  • Pirate articles:
    • Rules agreed to by the whole crew before setting sail
    • Covered: shares of loot, compensation for injuries, rules of conduct, punishments
    • When articles didn’t cover a situation, the crew acted as a judiciary
  • Share system:
    • Pay tied to collective plunder, not fixed wages
    • Aligns everyone’s incentives: lazy crew members hurt everyone’s share
    • \(\rightarrow\) Peer monitoring replaces top-down monitoring (walk the plank!)

Think-pair-share: wrapping up organization of OC

  • What problems do the pirate institutions solve? And through which mechanism?
    • Separation of powers \(\rightarrow\) ?
    • Pirate articles \(\rightarrow\) ?
    • Share system \(\rightarrow\) ?
  • Why did pirates need to constrain their captain while merchants needed to empower theirs?
    • What does this tell us about how who owns the ship shapes how it is run?
    • Other OC cases where ownership structure shapes how power is distributed?
  • Pirates and the gangs both solved organizational problems without law
    • What did they have in common? What was different?

For Monday: protection rackets and the Sicilian mafia

  • We have now completed part I of the course, which introduces foundational concepts
    • Definitions, the state-crime nexus, origins, and internal organization
  • Case studies begin on Monday
    • We zoom in on specific types of criminal organizations
  • Don’t forget to fill out the survey if you need help finding a group for the final project
  • Any questions before the quiz?
