Effects of Government Intervention

Chapter 12 ― Question 3
If a tariff is raised on a commodity,

  1. foreign producers charge a lower price
  2. foreign producers receive a higher price
  3. domestic producers receive a higher price
  4. domestic producers charge a lower price
    *C. The tariff raises the price of imports. This enables domestic producers to raise their prices. B is wrong because the tariff must be deducted from the higher price importers receive.

Chapter 12 ― Question 4
If the government sets a price floor above equilibrium price of a commodity, which of the following will happen

  1. an increase in tax revenues for the government
  2. an increase in demand for the commodity
  3. excess supply of the commodity
  4. excess demand for the commodity
    *C. Price floors above equilibrium price attract new suppliers, for instance, more workers seek jobs when the minimum wage has been raised. Answer A is nonsense. Government do not raise revenues by setting price floors. Answers B and D are also nonsense. Why should an increase in price lead to an increase in demand?

Chapter 12 ― Question 8
What precisely does it mean to say that suppliers must bear a tax because supply is inelastic?
* It means that they cannot lower quantity supplied. They supply a quantity that exceeds quantity demanded at the new price. As a result, they must lower their net prices.
