What are price controls?
Price controls are government-imposed limits on the price a good or service may be bought or sold for, either a maximum price ceiling intended to keep goods affordable or a minimum price floor intended to guarantee sellers a certain return, overriding the price that unrestricted supply and demand would otherwise set.

Core tenets
- Government-set price limit
- The state directly sets a legal maximum or minimum price for a specific good or service, rather than leaving the price to market negotiation alone.
- Ceilings versus floors
- A price ceiling caps how high a price may legally go, typically to protect buyers; a price floor sets a minimum, typically to protect sellers.
- Targeted intervention, not a full economic system
- Price controls are a specific policy tool applied to particular goods or services, used across a wide range of economic systems, not exclusive to any one of them.
How it works in practice
Price controls have been applied to goods ranging from rent and food staples to minimum wages and agricultural prices.
- Price ceiling
- A legal maximum price, such as rent control, is set below what an unrestricted market would otherwise charge.
- Price floor
- A legal minimum price, such as a minimum wage or agricultural price support, is set above what an unrestricted market would otherwise pay.
What it is often confused with
Price controls are a specific policy tool, not an indicator that a country has adopted central planning or socialism as a full economic system; many predominantly capitalist economies use targeted price controls in specific markets.
Criticisms and debates
Criticism of price controls centers on the shortages or surpluses that can result when a controlled price diverges from the market-clearing price.
Shortage critique
Economists commonly argue that a price ceiling set below the market-clearing price leads to shortages, since demand at the lower price exceeds the quantity suppliers are willing to provide.
Response: Defenders of targeted price controls argue that in specific cases, such as rent control paired with strong tenant protections, the goal of affordability can outweigh some efficiency loss, particularly for essential goods.
Surplus critique
Similarly, a price floor set above the market-clearing price, such as some agricultural price supports, can lead to oversupply the government must then purchase or otherwise absorb.
Response: Defenders argue that price floors for specific goods, such as a minimum wage, are intended primarily to protect a class of sellers, workers, rather than to clear a market efficiently, a different goal than pure economic efficiency.
Historical examples
- Rent control in New York City, ongoing
- A long-running price ceiling on certain residential rents, a widely studied and debated example of price control policy.
- Minimum wage laws, many countries
- A price floor on the price of labor, intended to guarantee workers a minimum level of pay regardless of what an unrestricted labor market might otherwise set.
