Price controls

Price controls are governmental restrictions on the prices that can be charged for goods and services in a market. The most common are prohibitions to charge more than X for goods or services (maximum price) or the prohibition on paying less than Y (minimum price).

Price controls subvert the market mechanism and thus impede the free interplay of the forces of supply and demand. Criticisms are generally divided into ethical and utilitarian arguments:

  • Utilitarian arguments focus on the effects that price controls have on the economy. By distorting supply and demand maximum prices (if set below the market rate) will cause shortages of the good in question. Minimum prices (if set above the market rate) tend to create a surplus of the good affected. Because Price controls can restrict exchanges which would have happened in a voluntary market, a priori benefiting both parties to the exchange, they destroy value and reduce economic growth.
  • Ethical criticism of Price controls focus on the fact that they are an attack on and . They are an imposition of the planners will on those of market participants and restrict voluntary trade. Enforcing price controls also requires a substantial attack on privacy and an increase of .
