5 Must Know Facts For Your Next Test

1. Economic surplus is the sum of consumer surplus and producer surplus, representing the total net benefit from a market transaction.
2. Price ceilings and price floors can distort the equilibrium price, leading to a reduction in the total economic surplus.
3. Price ceilings, which set a maximum legal price, can create a shortage and reduce both consumer and producer surplus.
4. Price floors, which set a minimum legal price, can create a surplus and reduce both consumer and producer surplus.
5. Maximizing economic surplus is a key goal in the analysis of market efficiency and the impact of government interventions.

Review Questions

• Explain how price ceilings impact the total economic surplus in a market.
  • Price ceilings, which set a maximum legal price, can reduce the total economic surplus in a market. By preventing the equilibrium price from being reached, price ceilings create a shortage, leading to a decrease in both consumer surplus and producer surplus. Consumers are unable to purchase the good at the higher price they are willing to pay, while producers are unable to sell the good at the higher price they are willing to accept, resulting in a net loss of economic surplus.
• Describe the relationship between equilibrium price and the maximization of economic surplus.
  • The equilibrium price in a market is the price at which the quantity demanded is equal to the quantity supplied, maximizing the total economic surplus. At the equilibrium price, the marginal benefit to consumers is equal to the marginal cost to producers, ensuring that all mutually beneficial trades are made. Any deviation from the equilibrium price, such as through the implementation of price ceilings or price floors, will lead to a reduction in the total economic surplus as some consumers and producers are unable to engage in beneficial transactions.
• Evaluate the impact of price floors on the distribution of economic surplus between consumers and producers.
  • Price floors, which set a minimum legal price, can reduce the total economic surplus in a market by creating a surplus. This surplus leads to a decrease in both consumer surplus and producer surplus. Consumers are unable to purchase the good at the lower price they are willing to pay, while producers are unable to sell the good at the lower price they are willing to accept, resulting in a net loss of economic surplus. The distribution of the remaining surplus is also affected, as the price floor disproportionately benefits producers at the expense of consumers, shifting the balance of economic surplus away from consumers and towards producers.
