Which of the following will cause an increase in consumer surplus?
a. An increase in the production cost of the good.
b. A technological improvement in the production of the good.
c. A decrease in the number of sellers of the good.
d. The imposition of a binding price floor in the market.
The correct answer and explanation is :
The correct answer is b. A technological improvement in the production of the good.
Explanation:
Consumer surplus refers to the difference between what consumers are willing to pay for a good or service and what they actually pay. In simple terms, it represents the benefit that consumers receive when they pay less for a product than the price they were willing to pay.
Now, let’s evaluate each option:
- a. An increase in the production cost of the good:
- If production costs increase, producers may raise prices to maintain their profit margins. This would lead to higher prices for consumers, which, in turn, reduces consumer surplus. Since consumers will be paying more for the same good, the consumer surplus decreases.
- b. A technological improvement in the production of the good:
- A technological improvement in production usually leads to lower production costs, which makes the good cheaper to produce. This reduction in cost can lead to lower prices for consumers, increasing their consumer surplus. Additionally, such improvements often increase supply, which can lead to a more favorable market equilibrium with lower prices and more quantity available for consumers, resulting in an increase in consumer surplus.
- c. A decrease in the number of sellers of the good:
- A decrease in the number of sellers typically leads to less competition in the market. With fewer sellers, the supply of the good may decrease, causing prices to rise. Higher prices mean consumers will have to pay more, thus reducing consumer surplus.
- d. The imposition of a binding price floor in the market:
- A binding price floor is a minimum price set above the equilibrium price. This results in a price that is higher than what would naturally occur in the market. With higher prices, consumers are likely to buy less of the good, reducing consumer surplus. A price floor creates a situation where the price is artificially inflated, causing consumers to lose out on the benefits of lower prices.
In summary, a technological improvement in production lowers costs, which can reduce prices and increase consumer surplus, making b the correct answer.
