Suppose a stock market boom makes people feel wealthier. The increase in wealth would cause people to desire: a) increased consumption, which shifts the aggregate-demand curve right. b) increased consumption, which shifts the aggregate-demand curve left. c) decreased consumption, which shifts the aggregate-demand curve right. d) decreased consumption, which shifts the aggregate-demand curve left.

a. Increased consumption, which shifts the aggregate-demand curve right.

Explanation:

When there is a boom in stockmarket which makes people wealthier, people's consumption would increase because of the desire and availability of money to purchase goods, which results in demand curve shifting right.

The boom in the stockmarket means people investment has appreciated hence are able to save and increase their consumption spending.

A shift in demand curve to the right means an increase in the quantity demand of goods and services while a shift in demand curve left means a decrease in the quantity demand of goods and services.

Other factor that could cause increased consumption and shifts in aggregate demand curve right is tax decrease. Tax is a compulsory levy imposed on an individual or an organization by the government.

When there is a tax decrease, people would be able to save more thus increase their desire to consume more hence demand curve would shift to the right.
