Economic Calculation Problem

The load-bearing theoretical argument against planned economies: without market prices, planners cannot know what to produce.

Definition

Mises (1920): without private capital-goods markets there are no prices, so rational allocation is impossible. Hayek (1945) sharpened it into the knowledge problem: prices carry dispersed, tacit, local knowledge no planner can collect; people can misreport to planners but “cannot lie to price signals.” The debate continued through Oskar Lange’s market-simulation reply and the modern “computers can do it” rejoinder. Marx’s own silence on how a socialist economy would calculate (Karl Marx wrote critique, not blueprint) is why the problem lands.

Key Properties

• The corpus’s right-lean sources treat it as dispositive; the genealogy source presents it as a live but serious challenge; no source in the corpus yet mounts a full left rebuttal — lint flag for balance.
• Standard illustrations: Soviet price bureau (200k prices/year vs. ~20M needed), nails by weight then count, the Trabant, East/West Berlin store counts.
• Distinct from the incentive argument (“nobody washes a rental car”) — sources often run them together.
