IB Economics - Price Floors in Economics

This study note for IB economics covers Price Floors in Economics

1. Introduction to Price Floors

A price floor is a minimum price set by the government above the equilibrium price in a market. The government imposes price floors to ensure that prices do not fall below a level deemed acceptable for producers or workers. Price floors can be seen in various markets, including agricultural products and labor.

2. Reasons for Imposing Price Floors

• Protecting Producers' Income: Governments impose price floors to ensure that producers, such as farmers, receive a minimum income, especially when market prices fall too low due to overproduction or market saturation.
• Ensuring Fair Wages: In labor markets, minimum wage laws serve as price floors to protect workers from being paid too low, ensuring a minimum standard of living.
• Stabilizing Markets: Price floors can stabilize market prices, providing predictability and security for producers, which can encourage investment and production.

3. Examples of Price Floors

• Agricultural Price Supports: Many countries implement price supports for agricultural products. For instance:
  • The European Union’s Common Agricultural Policy (CAP) includes price floors for certain crops and dairy products, ensuring farmers receive a minimum price.
  • In Canada, the supply management system sets price floors for dairy, poultry, and eggs to stabilize farmers' incomes.
• Minimum Wages: Different countries set different levels of minimum wages as a way to protect workers:
  • In Australia, the Fair Work Commission sets a national minimum wage, reviewed annually.
  • South Africa has a national minimum wage law aimed at reducing poverty and inequality.

4. Impact of Price Floors on Market Outcomes

• Surpluses: When a price floor is set above the equilibrium price, it often leads to excess supply (surplus) because consumers buy less at the higher price while producers are willing to supply more.
• Government Intervention: To manage surpluses, governments may:
  • Purchase and Store Surpluses: Governments may buy the excess products to maintain the floor price, which can lead to increased government expenditure.
  • Export Subsidies: Governments may subsidize the export of surplus goods to international markets.
  • Disposal through Aid Programs: Excess food products, for instance, might be distributed as food aid.
• Inefficient Resource Allocation: Resources may be inefficiently allocated as producers are incentivized to produce more of the surplus product, potentially at the expense of other products or industries.
• Welfare Impacts: The introduction of a price floor can lead to a welfare loss (deadweight loss), as the quantity traded in the market decreases, reducing consumer and producer surplus.

5. Consequences for Stakeholders

• Consumers: Generally, consumers face higher prices and reduced quantities of goods available. This can decrease consumer surplus and lead to reduced purchasing power, particularly affecting lower-income households.
• Producers: While some producers benefit from guaranteed higher prices, others might face unsold surplus and increased costs of storage or disposal.
• Government: The government incurs costs through purchasing surplus products, providing subsidies, or managing disposal programs. These interventions can strain public finances and may require increased taxes or borrowing.

6. Real-World Applications

• Agriculture in Japan: Japan maintains high price floors for rice to protect domestic farmers, despite rice being cheaper on international markets.
• Minimum Wage in Brazil: Brazil’s minimum wage policy aims to reduce poverty and inequality, impacting both urban and rural labor markets.

7. Cross-Curricular Connections

• History and Social Studies: Study of historical price control policies and their social impacts.
• Political Science: Examination of government policies, welfare economics, and the role of public intervention in markets.
• Geography: Analysis of regional variations in agricultural production and how they influence price floor policies.
• Ethics: Discussion on the moral implications of price controls and economic equity.

8. Glossary

• Consumer Surplus: The difference between the maximum price consumers are willing to pay and the market price they actually pay.
• Deadweight Loss: A loss of economic efficiency that can occur when the equilibrium for a good or service is not achieved.
• Equilibrium Price: The price at which the quantity demanded equals the quantity supplied.
• Minimum Wage: The lowest legal wage that can be paid to workers, serving as a price floor in the labor market.
• Price Floor: A government-imposed minimum price for a good or service.
• Producer Surplus: The difference between the minimum price producers are willing to accept and the market price they receive.
• Surplus: The amount by which the quantity supplied of a product exceeds the quantity demanded at the current price.
