The graph gives an economy's AE curve when the economy is in long-run equilibrium. Equilibrium expenditure is $12 trillion. Draw a new AE curve that shows the effect of an increase in investment. Label it AE₁. Draw a point at the new equilibrium expenditure. Label it B. Draw another AE curve that shows equilibrium expenditure in the short run. Label it AE2. Draw a point at the short-run equilibrium. Label it C. Finally, draw the AE curve when the economy returns to long-run equilibrium. Label it AE3. 16- 14- 12- 10- Aggregate expenditure (trillions of 2012 dollars) 10 A 45 degree line AEO 15 11 12 13 14 Real GDP (trillions of 2012 dollars) >>> Draw only the objects specified in the question. 16
