The correct answer is:
b. Consumer surplus decreases.
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 is a measure of consumer welfare and is graphically represented as the area between the demand curve and the price level.
When the price of oak lumber increases, it directly impacts the cost of producing oak cabinets. This is because oak lumber is a key input in the production of oak cabinets. The increased cost of lumber leads to an increase in the overall price of oak cabinets in the market, as producers will pass on the higher production costs to consumers in the form of higher prices for cabinets.
Here’s how this affects consumer surplus:
- Price Increase: As the price of oak cabinets rises due to higher lumber costs, consumers will either be willing to purchase fewer cabinets at the new, higher price or they may decide not to purchase at all. This results in a reduction in the quantity of oak cabinets demanded.
- Loss of Consumer Surplus: With the price increase, consumers who were previously willing to buy the cabinets at a lower price no longer benefit from the same amount of surplus. The area representing consumer surplus shrinks as consumers either reduce their purchases or face higher prices than before.
- Reduction in Welfare: The increase in price leads to a loss in consumer welfare because consumers are now paying more for the same good, and some consumers may no longer be able to afford the cabinets. This reduced consumer surplus represents a net loss in well-being for consumers.
Thus, the overall effect of the price increase in oak lumber is a decrease in consumer surplus, as higher prices make the good less accessible or desirable for consumers.
