Decision Accounting (DA-1): From Missing Rationales to Mandatory Reconstruction

core
Core Claim

Hollow wins dominate when system welfare is excluded from the decision record

Boeing 737 MAX, Purdue Pharma, Silicon Valley Bank, and Volkswagen all show the same pattern: private parties gain while the shared system degrades, because the welfare-relevant tradeoff was never recorded before commitment.

game
Flawed Game

Bilateral authorization games exclude the system from the payoff space

Under the Missing System Theorem, outcomes that look Pareto-optimal inside the firm can degrade the broader system. The canonical signature is the Hollow Win: C=0, A=1, B=1.

framework
DA Framework

Decision Accounting requires a 17-field record before material decisions

Fields 1–15 (WHO, WHAT, WHY, PREDICTION, etc.) follow from adversarial reconstruction demands. Field 17 is the structural addition: it forces the institution to book the system-welfare term.

theory
Chain

Complete DA records shrink the equilibrium set and close ex post escape routes

2 shows that mandatory records raise expected sanctions for welfare-negative decisions. Theorem 3 shows that the PREDICTION field closes the unforeseeability claim.

beta
Welfare Beta

System welfare cost per dollar of revenue ranges from 0.8 to 167 across cases

Boeing: βW=0.8–1.3 (50–80B system cost vs. 60B revenue). Purdue: βW=14.3 (500B system cost vs. 35B revenue). SVB: βW=8–16. Volkswagen: βW=1–2.

boeing
Case: Boeing

Boeing and airlines gained 32B+; 346 died; system cost 50–80B

The missing DA record is the contemporaneous rationale: accepting a new failure pathway for schedule and sales continuity. No field required the program to state that tradeoff before commitment.

purdue
Case: Purdue

Purdue and its channel gained 35B; 200,000–500,000 died; system cost 500B–$1T

The missing DA record is the marketing and distribution rationale. Internal documents later showed executives knew about diversion but continued the strategy.

svb
Case: SVB

SVB gained 1.8B in interest income; failure cost FDIC 16B; system cost $50–100B

The missing DA record is the treasury strategy rationale. No document required the board to state the public-backstop exposure before committing to duration concentration.

vw
Case: Volkswagen

VW gained 30B in U.S. diesel sales; 50–1,000 premature deaths; system cost 30–60B

The missing DA record is the defeat-device rationale. Engineers and executives knew the software was illegal but continued to meet sales targets.

intract
Intractability

The barrier to DA adoption is institutional, not physical

6 states that no physical law prevents complete DA records. The constraint is the private value of ambiguity, the cost of record production, and the absence of mandatory requirement.

change
Game Change

DA transforms the authorization game from Hollow Win to accountable choice

The transformation R alters payoff structure, information structure, and enforcement structure. The Hollow Win is no longer the structurally dominant equilibrium.

policy
Policy Implication

Mandatory DA records shift outcomes away from Hollow Wins

The six theorems show that complete records restrict the equilibrium set, limit ex post rationalization, and make system-welfare costs legible before commitment. The rule change is achievable through statute, regulation, or board rule.
