A

Increase in demand due to higher purchasing power

B

Decrease in supply of luxury goods

C

Price decrease of luxury goods

D

Increase in consumer population

Understanding the Answer

Let's break down why this is correct

Answer

The rise in consumer income makes luxury goods more affordable and attractive, so people want to buy more of them. This higher willingness to buy shifts the demand curve for those goods to the right. As a result, the equilibrium price and the quantity sold both rise. For example, if people suddenly earn more money, they might buy a new designer handbag that they previously could not afford, pushing the market price up and the sales volume higher. Thus, the change in equilibrium is driven by the income effect that increases demand.

Detailed Explanation

More money lets people buy more luxury items. Other options are incorrect because Some think a smaller supply makes buyers want more; Others think a lower price causes the rise.
