Price Floor Impact on Market Outcome

Binding price floors typically cause excess supply and decreased total economic surplus.

Learning Objective

  • Show how price floors contribute to market inefficiency


Key Points

    • A price floor is economically consequential if it is greater than the free-market equilibrium price.
    • Price floors lead to a surplus of the product.
    • Supply surplusses created by price floors are generally added to producer's inventory or are purchased by governments.
    • Consumer surplus is the gain obtained by consumers because they can obtain a product for a lower price than they would be willing to pay.
    • Producer surplus is the benefit producers get by selling at a price higher than the lowest price they would sell for.

Terms

  • free-market equilibrium price

    The price established through competition such that the amount of goods or services sought by buyers is equal to the amount of goods or services produced by sellers

  • price floor

    A mandated minimum price for a product in a market.


Full Text

A price floor will only impact the market if it is greater than the free-market equilibrium price. If the floor is greater than the economic price, the immediate result will be a supply surplus. As you can see from , a higher base price will lead to a higher quantity supplied. However, quantity demand will decrease because fewer people will be willing to pay the higher price. This will lead to a surplus of supply.

Surplus from a price floor

If a price floor is set above the free-market equilibrium price (as shown where the supply and demand curves intersect), the result will be a surplus of the good in the market.

A price floor will also lead to a more inefficient market and a decreased total economic surplus. Economic surplus, or total welfare, is the sum of consumer and producer surplus. Consumer surplus is the monetary gain obtained by consumers because they are able to purchase a product for a price that is less than the highest that they are willing pay. Producer surplus is the amount that producers benefit by selling at a market price that is higher than the least they would be willing to sell for. An effective price floor will raise the price of a good, which means that the the consumer surplus will decrease. While the effective price floor will also increase the price for producers, any benefit gained from that will be minimized by decreased sales caused by decreased demand from consumers due to the increase in price. This translates into a net decrease total economic surplus, otherwise known as deadweight loss.

Since well designed price floors create surpluses, the big issue is what to do with the excess supply. The first option is to let inventories grow and have the private producers bear the cost of storing it. The other option is for the government that set the price floor to purchase the excess supply and store it on its own. The government could then sell the surplus off at a loss in times of a food shortage.
