AI is collapsing coordination costs, but firms may still outlast the market

AI is changing the economics of the firm
The post starts from Ronald Coase’s 1937 question — why firms exist if markets coordinate so well — and his answer in The Nature of the Firm: market coordination is not free, because discovering prices, negotiating, monitoring, and enforcing all carry costs.
The author argues that AI is now collapsing many of those coordination costs, which leads people to claim the firm will dissolve into a thin protocol with a swarm of agents. But that conclusion may be too fast.
The stronger claim
Instead of saying Coase is obsolete, the right move is to apply Coase again in a new environment:
- firms still exist wherever coordination is too costly to leave to the market
- AI changes which coordination costs matter
- the key question becomes which activities are now better bought from the market, and which still belong inside the firm
In short, AI does not automatically eliminate companies; it changes the boundaries where firms make sense.
