Study Notes

Elasticity of Demand

  • When demand is elastic, percentage change in quantity demanded will be greater than the percentage change in price.
  • If there is an increase in the price of the good, the revenue will fall.

Comparative Advantage

  • Individuals and countries with comparative advantage in producing goods should specialize in the production of these goods.
  • Gains from trade are maximized when each country specializes in the production of the good for which they have a comparative advantage and trade those goods.
  • The lower the opportunity cost of producing a good, the more comparative advantage an individual has in that good.

Taxes on Sellers

  • Sellers get a lower price for their product before paying the tax.
  • The deadweight loss from a tax is greater when the demand and supply for the good are more elastic.

Price Ceiling

  • A binding price ceiling will cause a shortage in the market and will generally decrease the quantity supplied and increase the quantity demanded.
  • A price ceiling is non-binding when it is set above the equilibrium price.

Price Floor

  • Buyers would lobby for a price floor, whereas sellers would lobby for a price ceiling.
  • A binding price floor causes a surplus in the market.

Monetary Injections

  • An increase in the quantity of money in the economy will stimulate the overall level of spending.
  • An increase in the quantity of money will, over time, encourage firms to hire more workers and produce a larger quantity of goods and services.
  • An increase in the quantity of money in the economy will lead to lower unemployment levels in the short run.
  • Higher prices are a consequence of an increase in the quantity of money in the economy.

Tariff

  • A tariff causes deadweight loss, represented by D+F on the graph.
  • A tariff is a tax levied on imported goods.
  • Tariffs are used by countries to protect domestic industries from foreign competition.

International trade

  • A country has a comparative advantage in producing a good if its domestic price for the good is lower than the world price.
  • If a country opens up trade, a domestic price lower than the world price indicates that country will become an exporter of that good.

Government Revenue

  • The government can increase tax revenue if it lowers the tax on a good when the tax is initially set at a high rate.
  • This is because the Laffer curve illustrates that when a tax is set at a high rate, a reduction in the tax may result in an increase in the tax base as more people are willing to pay the taxes.
