What does the aggregate demand (AD) curve illustrate?

• A. Shows the unemployment rate at different price levels.
• B. Shows the relationship between the aggregate price level and the quantity of aggregate output demanded by households, businesses, the government, and the rest of the world.
• C. Shows the supply of goods at different price levels.
• D. Shows the relationship between consumer confidence and inflation.

Answer: (D)

The aggregate demand curve shows the relationship between the overall price level and the total quantity of goods and services demanded in the economy by households, firms, the government, and the rest of the world. As the price level falls, real purchasing power rises and interest rates tend to fall, which boosts spending and can also improve net exports. This makes the quantity of output demanded rise when prices drop, and fall when prices rise—the downward slope results from effects like the wealth effect, the interest rate effect, and the international (exchange-rate) effect. Descriptions about unemployment at different price levels, or about the supply of goods at different price levels, describe different concepts (unemployment patterns or aggregate supply) and aren’t what the aggregate demand curve portrays. A link between consumer confidence and inflation isn’t the standard presentation of this curve either.
