Balancing Acts: Effects of Price Controls on Market Equilibrium

Governments often step in to regulate prices when they are deemed too high or too low compared to desired levels. These interventions are analyzed within the framework of perfect competition to understand their impact on the affected markets.

Price Ceilings: Impact on Wheat Markets and Consumer Struggles

• Definition: It’s not uncommon for governments to set a maximum allowable price for certain goods, known as a price ceiling.
• Price Ceilings on Essential Good: These price ceilings are typically imposed on essential items like wheat, rice, kerosene, and sugar, etc.
• Below the market Prices: They are set below the market-determined prices to ensure affordability for a section of the population.

Let’s examine the effects of a price ceiling on market equilibrium using the example of the wheat market.

• In Figure, we have the market supply curve (SS) and the market demand curve (DD) for wheat.
• The Price Ceiling and quantity are denoted as p* and q* respectively.

Effect of Price Ceiling in Wheat Market

The equilibrium price and quantity are p* and q* respectively. Imposition of price ceiling at pc gives rise to excess demand in the wheat market.

• Excess Demand: When the government imposes a price ceiling at pc, which is lower than the Price Ceiling, there is excess demand for wheat at that price.
  • Consumers demand qc kilograms of wheat, while firms supply q’c kilograms.
  • This government intervention, aimed at helping consumers, can lead to a wheat shortage.
• A Rationing System: To distribute the quantity of wheat (q’c) among consumers, a rationing system is often employed.
  • Limiting Individual Purchases: Ration coupons are issued to consumers, limiting individual purchases to a certain amount of wheat. 
  • Fair Price Shops: This stipulated amount of wheat is sold through ration shops, also known as fair price shops.

Price ceilings, when combined with rationing of goods, can lead to various adverse consequences for consumers:

• Long Queues: Consumers may be required to stand in long queues at ration shops to purchase the goods.
• Dissatisfaction and Black Market: Since the rationed quantity may not satisfy the needs of all consumers, some may be willing to pay a higher price to obtain additional goods. 
  • This situation can create a black market where goods are sold at prices above the government-imposed ceiling.

Price Floor: Balancing Stability and Market Excess

• • Definition: Price floors are government-imposed lower limits on the prices of certain goods and services.
  • Aim: They are set to ensure that the prices do not fall below a specific level, which is typically higher than the market-determined price for these goods.
  • Examples: Two common examples of price floors are agricultural price support programs and minimum wage legislation.
  • When a price floor is imposed, it can lead to an excess supply in the market.

• Example: 

• • If the floor price (pf) is set higher than the Price Ceiling (p*), consumers demand qf units of the commodity,
  • While producers are willing to supply q’f units, resulting in an excess supply of qf – q’f units.

Effect of Price Floor on the Market for Goods

The market equilibrium is at (p*, q*). Imposition of price floor at pf gives rise to an excess supply.

Agricultural Price Support Programs: Ensuring Farmers’ Minimum Income

• Minimum Price: In agricultural price support programs, the government sets a floor price for agricultural goods, ensuring that farmers receive a minimum price for their produce.
• Higher than Market Price: This floor price is usually higher than the market price.
• The Government Intervention:  Sometimes the government may need to purchase the surplus quantity of goods at the predetermined price to prevent prices from falling due to excess supply.

Minimum wage legislation: Upholding Fair Income for Laborers

• It establishes a minimum wage rate for laborers, guaranteeing that their wages do not fall below a certain level, typically above the equilibrium wage rate.
• This intervention aims to support farmers by ensuring they receive a minimum income for their produce.

Conclusion

• The concept of market equilibrium is a fundamental pillar of economics, offering valuable insights into how supply and demand interact to determine prices and quantities in a competitive marketplace.
• As explored in this chapter, market equilibrium represents a state of balance where the forces of supply and demand align, resulting in stable prices and optimal allocation of resources.
• Understanding market equilibrium is essential for businesses, policymakers, and consumers alike. It provides a framework for predicting price changes, assessing market efficiency, and making informed decisions.
• However, it’s important to recognize that markets are dynamic and constantly evolving, which means that achieving and maintaining equilibrium is an ongoing process.
