Questions: Which of the following is not a property of the aggregate demand curve? A It shows the relationship between the overall price level and the level of consumption. (B) It slopes downward. (C) It maps to the price level on the vertical axis and output on the horizontal axis. (D) It shows the relationship between the overall price level and the level of total demand.

The answer is the first one (A): It shows the relationship between the overall price level and the level of consumption.

Explanation for each option:

A. It shows the relationship between the overall price level and the level of consumption.

• This is incorrect because the aggregate demand curve represents the relationship between the overall price level and the total quantity of goods and services demanded in an economy, not just consumption. It includes consumption, investment, government spending, and net exports.

B. It slopes downward.

• This is correct. The aggregate demand curve typically slopes downward, indicating that as the price level decreases, the quantity of goods and services demanded increases.

C. It maps to the price level on the vertical axis and output on the horizontal axis.

• This is correct. The aggregate demand curve is plotted with the price level on the vertical axis and real GDP (output) on the horizontal axis.

D. It shows the relationship between the overall price level and the level of total demand.

• This is correct. The aggregate demand curve illustrates the relationship between the overall price level and the total demand for goods and services in an economy.

In summary, option A is not a property of the aggregate demand curve because it incorrectly focuses solely on consumption rather than total demand.
