## Definition
**Price controls** are government-imposed limits on the price at which a good or service may be bought or sold. A *price ceiling* sets a maximum price (below the market-clearing level); a *price floor* sets a minimum price (above the market-clearing level). Hazlitt argues, following the Austrian tradition, that both forms of control disrupt the price mechanism and produce consequences opposite to their stated intentions.
## The Price Mechanism
Before analysing controls it is necessary to understand what prices do. In a free market, prices aggregate and transmit dispersed information about relative scarcity and consumer preference. A rising price signals to producers that demand exceeds supply; they expand output or enter the market. A falling price signals excess supply; producers contract or exit. No central authority needs to direct this process — the price system coordinates millions of independent decisions.
Hazlitt quotes Adam Smith approvingly: every consumer's purchase is a vote for more production of that item. Price is the ballot paper.
## Price Ceilings
A ceiling below the market price makes production less profitable or unprofitable:
1. **Artificial scarcity:** Producers reduce supply or exit the market. The quantity supplied falls below the quantity demanded — a shortage.
2. **Black markets:** Transactions move underground at prices above the legal ceiling, since the underlying demand has not changed.
3. **Quality deterioration:** Unable to charge higher prices, producers cut costs through lower quality.
Classic examples: rent control (shortage of rental housing, deterioration of housing stock), energy price caps (queues and rationing), food price ceilings in wartime (hoarding and black markets).
## Price Floors
A floor above the market price makes the controlled good artificially expensive:
1. **Artificial surplus:** Producers are attracted to the above-market return; consumers buy less at the higher price. Quantity supplied exceeds quantity demanded — a glut.
2. **Misallocation of capital:** Capital flows into the subsidised sector rather than into more productive uses.
3. **Third-party harm:** Consumers who pay the inflated price have less to spend elsewhere — a dispersed, unseen cost.
Example from Hazlitt: a government floor price for wheat benefits wheat farmers visibly while harming consumers and capital allocation invisibly.
## Minimum Wage as a Price Floor on Labour
Hazlitt treats the minimum wage as a price floor applied to labour. Its effects follow the same logic:
- Employers facing a mandated wage above the market-clearing rate will employ fewer workers, reduce hours, or substitute capital for labour.
- The workers most affected are those at the bottom of the productivity distribution — the very people the policy targets. Their marginal product is below the floor price; no employer will pay more for their labour than it produces.
- The seen effect is higher wages for those still employed. The unseen effect is unemployment or reduced hours for those no longer employable at the higher rate.
Hazlitt's position: wages in a competitive market tend toward the worker's marginal product. Durable wage increases come from productivity gains, not legal mandates.
## Epistemic Caveat
Price control effects are accepted in their direction by mainstream economics (supply and demand analysis). The contested questions are magnitudes. Labour-market economists studying minimum wage impacts find complex effects — including cases where modest increases produce little measurable unemployment, especially in monopsonistic local markets. Hazlitt writes from an Austrian framework that assumes competitive, flexible markets; his conclusions are most robust in that context.
