Which of the following will cause a decrease in consumer surplus?
a. An increase in the number of sellers of the good.
b. A decrease in the production cost of the good.
c. Sellers expect the price of the good to be lower next month.
d. The imposition of a binding price floor in the market.
The correct answer and explanation is :
The correct answer is d. The imposition of a binding price floor in the market.
Explanation:
Consumer surplus refers to the difference between what consumers are willing to pay for a good or service and what they actually pay. It represents the benefit consumers get from participating in the market. Various factors can affect consumer surplus, either increasing or decreasing it.
Let’s examine each option:
- a. An increase in the number of sellers of the good:
- An increase in the number of sellers typically leads to more competition. This usually results in lower prices and more options for consumers. As a result, consumer surplus would likely increase because consumers can either pay less for the same goods or enjoy better quality goods at the same price.
- b. A decrease in the production cost of the good:
- A decrease in production costs generally leads to a reduction in prices since suppliers can produce more efficiently. This price reduction benefits consumers, increasing consumer surplus. Consumers pay less for the same goods, so their surplus increases.
- c. Sellers expect the price of the good to be lower next month:
- If sellers expect lower prices in the future, they may hold back some of their goods from the market to sell later at a higher price. In the short term, this could lead to lower current prices, benefiting consumers and potentially increasing consumer surplus. However, the primary effect of this expectation is generally to increase surplus in the short term due to lower prices.
- d. The imposition of a binding price floor in the market:
- A binding price floor is a minimum price set above the equilibrium price. When this occurs, sellers cannot sell below this price, which results in a surplus of goods in the market (excess supply). Consumers face higher prices and fewer goods available at those prices. As a result, consumer surplus decreases because consumers are paying higher prices than they would have in an unregulated market, and they may not be able to purchase as much of the good. The higher price reduces the difference between what consumers are willing to pay and what they actually pay, thus decreasing their surplus.
Therefore, the correct answer is d: the imposition of a binding price floor in the market reduces consumer surplus.
