Applying the System Asset Pricing Model to Private Prisons and the Carceral State: Measuring the System Welfare Cost of For-Profit Incarceration

core-claim
Core claim

Each dollar of private carceral revenue destroys $12.08 in system welfare

The System Asset Pricing Model (SAPM) measures welfare co-destruction per dollar of annual industry revenue. For the for-profit carceral-industrial complex, the system beta βW = 12.09 — every dollar of private revenue destroys $12.08 in welfare.

sapm-logic
SAPM logic

SAPM adapts CAPM's pricing logic to measure welfare co-destruction

CAPM measures an asset's financial co-movement with the market. SAPM retains the structure but measures welfare co-destruction: βW = W / Π. For the carceral state, βW = 12.09, meaning each dollar of industry revenue destroys $12.08 in system welfare.

baseline
Cooperative baseline

The cooperative baseline exists in every peer democracy

The welfare costs are measured against a cooperative baseline: peer-nation incarceration rates (~95–110 per 100,000), public operation, fair-market pricing, and adequate indigent defense. Norway, Germany, and Portugal already operate this baseline.

channels
Five welfare channels

Five monetized channels produce $96.7B in annual welfare cost

The verified Monte Carlo model calibrates five channels: over-incarceration (38.1B), human capital destruction (23.8B), monopoly extraction (19.0B), institutional defense failure (9.5B), and governance-political feedback ($4.8B).

monte-carlo
Monte Carlo results

βW never falls below 1 across 100,000 draws

The verified Monte Carlo simulation with 100,000 draws yields a median βW = 12.09, 90% CI [8.8, 16.8]. P(βW < 1) = 0.0000% — the system is never welfare-neutral.

pigou-coase
Pigou/Coase failure

Pigouvian taxation and Coasean bargaining both fail in carceral markets

Pigouvian taxation fails because the taxing authority is the customer, welfare costs are diffuse, and the industry captures regulators. Coasean bargaining fails because incarcerated people have no bargaining power — a mother pays $24.95 for a 15-minute call because Securus pays the facility a kickback of 50–84% of revenue.

Institutional PST

No impossibility theorem — the barrier is political, not physical

Unlike chemical or energy domains, carceral welfare costs arise from institutional design, not irreducible physical processes. The Missing System Theorem's impossibility result does not apply because peer democracies already operate the cooperative baseline.

governance-capture
Governance capture

Political spending is a capital investment in externality production

The industry spends 53M+ annually on lobbying and campaign contributions to shield 5B in revenue — a return on investment exceeding 500:1. This governance-capture channel amplifies welfare costs by sustaining mass incarceration policy.

timeline
Reform timeline

At current pace, OECD convergence takes until year 2200

The U.S. prison population is declining at ~1% per year. At that rate, halving the prison population takes until 2093, and reaching peer-nation levels takes until approximately 2200 — accumulating over $10 trillion in welfare destruction.

reforms
Game transformations

Four institutional reforms can transform the game

The paper identifies specific game-transformation mechanisms: outcome-based contracting, elimination of occupancy guarantees, prohibition of site commissions, and structural decarceration toward peer-nation norms. Arizona's HB 2783 ties 10% of payment to a 5% recidivism reduction.

cross-domain
Cross-domain comparison

Carceral βW ranks second among all calibrated SAPM domains

The carceral state's βW = 12.09 is higher than Bitcoin mining (βW = 5) and PFAS manufacturing (βW = 35) — though PFAS destroys more per dollar. The carceral complex is the most welfare-destructive institutional arrangement calibrated to date.

verdict
Verdict

The for-profit carceral-industrial complex is a welfare extraction engine

The scarlet number: βW = 12.09. The system welfare cost: $96.7B per year. The verdict: the for-profit carceral-industrial complex is not a market — it is a welfare extraction engine housed inside the machinery of the state. Reform is politically feasible because the cooperative baseline already exists in every peer democracy.
