"Exchange is the fundamental social relation." — Ludwig von Mises, Human Action, Ch. X (paraphrased for length)

Chapter X — Exchange Within Society

What Mises argues

Mises distinguishes autistic exchange — action that substitutes one state for another without another person's involvement (a hermit tending his garden) — from interpersonal exchange, where one person's action is coordinated with another's. Interpersonal exchange is the seed of society.

He then draws the book's most consequential social distinction: between the contractual (coordinate) bond and the hegemonic bond. In the contractual bond, parties meet as equals under the law, each acting on his own plan, each expecting to gain; the market is the great instance. In the hegemonic bond, one will directs and others obey — the relation of superior to subordinate, of the commander to the commanded. A society may combine both, but the two are structurally opposite: one coordinates independent plans, the other imposes a single plan. All of catallactics — the economics of the market — studies the contractual bond.

The lineage

Mises' own framework, giving precise economic content to the classical-liberal contrast between society by consent and society by command.

The Framework's Reading

This chapter is the doorway to everything the Framework cares about most. The contractual bond is exactly the network whose signals are prices — the dispersed, coordinate discovery process the Atlas renders as the Price Signal. The hegemonic bond, wherever it replaces exchange with command, destroys those signals and the information they carry. When the Framework criticizes a centrally administered interest rate or a fixed gold price, the objection is precisely this: a hegemonic act imposed on what should be a contractual, price-discovered magnitude.
