Introduction

A price floor creates an excess supply or surplus, and a decision must be made about what to do with the excess supply or surplus.

Market for eggs


How do you think the rationing should be resolved?

Select all the possibilities that you think apply.








All the above is possible but it leads to inefficiencies.


Even a policy whereby the government buys the surplus eggs and exports them is not without costs to society. The government would probably not be able to export the eggs at the price it paid for them, but at a lower price, which would therefore involve a loss. It might also have serious consequences for the producers of eggs in the country importing the eggs.

If producers were responsible for destroying the surplus, then the suppliers who are able to sell eggs at the price floor would be better off, while those who cannot sell their eggs owing to low quantity demanded would lose out.

Quotas would probably lead to lobbying, bribery and corruption.

Paying farmers not to produce would probably lead to more farmers claiming that they intend producing eggs. Another possible result of binding price floors is that inefficient farmers are kept in business and produce goods of which an excess supply already exists, while other goods have to be imported.

Price floors usually have the following consequences on goods and services where the minimum price is higher than the equilibrium price (or market clearing price):

  • A persistent surplus (excess supply) develops.
  • Consumers, including poor households, have to pay artificially high prices.
  • Inefficient producers are protected and manage to survive.
  • The disposal of the market surpluses usually entails further costs to tax payers and welfare losses to society.
  • To avoid these unintended consequences, government is forced to increase its intervention in the market and thus impose even more costs on the system.
  • Price floors also create winners and losers. Those producers that can sell at the higher price benefit, while consumers lose since they have to pay a higher price. At this higher price, there are fewer consumers of the good or service.

As you can see, government intervention through price ceilings and price floors can have extremely negative consequences.


Activity

The following demand and supply curves for the market for milk illustrate the impact of a price floor of R12,00:

Which one of the following statements is correct with regard to the above?




Think again.

We are dealing with an excess supply.

Correct. A consequence of a price floor is that it interferes with the rationing function of the price mechanism, resulting in an excess supply. In the absence of the price floor, the equilibrium price will be reached and there will be no excess demand or excess supply.

When a price floor of R12,00 is imposed, the quantity demanded is 20 000 litres of milk, while the quantity supplied is 60 000 litres of milk. This gives us an excess supply of 40 000 litres of milk. Society must now decide what should be done with this excess supply of milk.

Think again.

The price floor (R12) is higher than the equilibrium price (R8).

Indicate whether the following statements are true or false:

At a price floor of R12,00, more buyers can purchase milk compared to the equilibrium position.



Think again.

The statement is false.  Less milk is bought.

Correct.  The statement is false.

At the equilibrium price of R8,00, the purchase of milk is 40 000 litres, while at a price of R12,00, it is only 20 000. Less milk is bought at R12,00 compared to R8,00 – which is the equilibrium price.

At a price floor of R12,00, a higher quantity of milk is supplied compared to the equilibrium position.



Correct.  The statement is true.

At the equilibrium price of R8,00, the quantity supplied is 40 000, while at a price of R12,00 – the floor price – the quantity supplied is 60 000. A higher quantity of milk is therefore supplied at R12,00 than at R8,00.

Think again.

The statement is true. There is indeed an excess supply.

If the price floor is lower than the equilibrium price, it will have no impact.



Correct. The statement is true.

The floor price is only binding if it is higher than the equilibrium price.

Think again.  The statement is true.

The floor price is only binding if it is higher than the equilibrium price.

More people are excluded from buying milk at a price floor higher than at the equilibrium position.



Correct.  The statement is true.

A negative consequence of a price floor is that fewer people are willing and able to purchase the product.

Think again. The statement is true.

A negative consequence of a price floor is that fewer people are willing and able to purchase the product.

A price floor creates an excess supply, and society needs to decide how to deal with this excess supply. Which of the following are possible ways to deal with this excess supply? Select all answers that apply.

  1. Buyers should be placed on a waiting list.
  2. A production quota system should be implemented whereby government would limit the production of product.
  3. The supplier should decide who should be able to obtain the product.
  4. Government should purchase the surplus production.
  5. Government should decide who should be able to obtain the product.
  6. The surplus should be destroyed by the producers.

b, c and f.

The following are all possible measures to deal with the excess supply:

  • A production quota system should be implemented whereby government would limit the production of product.
  • Government should purchase the surplus production.
  • The surplus should be destroyed by the producers.

The others are ways to deal with an excess demand:

  • Buyers should be placed on a waiting list.
  • The supplier should decide who should be able to get hold of the product.
  • The government should decide who should be able to get hold of the product.

Consider the following argument:

One way to deal with a surplus of milk that results from a price floor that is higher than the equilibrium price is to give the surplus away for free.

  1. The argument is correct since the milk has been produced and consumers will be better off.
  2. The argument is incorrect since it will undermine the price floor since people who are willing to purchase it at R12,00 will try to obtain it for free and people who can obtain it for free can sell it for less than R12,00.
  3. The argument is incorrect since there is no surplus when the price floor is higher than the equilibrium price.

b.

It will undermine the price floor since people who are willing to purchase it at R12,00 will try to obtain it for free. It might also happen that people who obtain it for free can then sell it at a lower price, thereby undermining the floor price.
