- 3. Determinants of aggregate demand The following graph shows an increase in aggregate demand (AD) in a hypothetical country. Specifically, aggregate demand shifts to the right from AD₁ to AD2, causing the quantity of output demanded to rise at all price levels. For example, at a price level of 140, output is now $400 billion, where previously it was $300 billion. 170 PRICE LEVEL 160 150 140 120 110 100 90 0 +--+ AD2 AD1 600 100 200 300 400 500 OUTPUT (Billions of dollars) 700 800arrow_forwardUsing an AD/AS diagram (starting from long-run/full employment equilibrium), graphically show and verbally describe how each of the following events would affect the U.S. economy's equilibrium real GDP and price level. a.

- Aggregate Demand and Aggregate Supply (AD-AS) Model (Chapter 13) 5.1 Why does the short-run aggregate supply curve slope upward? 5.2 Explain why the long-run aggregate supply curve is vertical. Then, explain how each of the following events would affect the long-run aggregate supply curve. A lower price levels b. A decrease in the labor force A decrease in the quantity of capital goods d. Technological change a. с. 5.3. Starting from long-run equilibrium, use the basic aggregate demand and aggregate supply diagram to show what happens in both the long run and the short run when there is a decline in wealth. Explain how the economy moves back to full employment.arrow_forwardWhich of the following would NOT cause a shift in AD? Select one: a. A reduction in interest rates b.
