# Coasean Bargaining at Scale

Krier argues AGI agents as personal advocates can dramatically reduce transaction costs, enabling Coasean bargaining at societal scale. Shifts governance from top-down central planning to bottom-up market coordination.

Key arguments:
- Coasean private bargaining has been theoretically sound but practically impossible due to prohibitive transaction costs (discovery, negotiation, enforcement)
- AI agents solve this: instant communication of granular preferences, hyper-granular contracting, automatic verification/enforcement
- Three resulting governance principles: accountability (desires become priced offers), voluntary coalitions (diffuse interests band together at nanosecond speed), continuous self-calibration (rules flex based on live preference streams)
- "Matryoshkan alignment" — nested governance: outer (legal/state), middle (competitive service providers), inner (individual customization)
- Critical limitations acknowledged: wealth inequality, rights allocation remains constitutional/normative, catastrophic risks need state enforcement
- Reframes alignment from engineering guarantees to institutional design

Directly relevant to [[coordination failures arise from individually rational strategies that produce collectively irrational outcomes]] and [[decentralized information aggregation outperforms centralized planning because dispersed knowledge cannot be collected into a single mind]].
