Problem 32A-02 Refer to the figures below and assume that @, is $400 and @2 is $500, the price level is stuck at Pil and the slopes of the AE lines in Figure (a) are 0.75 and equal to the MPC. Aggregate Expenditures Model Aggregate Demand-Aggregate Supply Model Aggregate expenditures (billions of dollars) Price level AD AD restic output, GDP Real domestic output, GDP Instructions: Enter your answers as a whole number. a. In what direction and by how much does the aggregate expenditures schedule in Figure (a) need to shift to move the aggregate demand curve in Figure (b) from AD, to ADZ? AE needs to (Click to select) by $ billion. What is the multiplier in this example? b. Given the multiplier, what must be the distance between AD, and the broken line to its right at P (the initial shift following the increase in expenditures represented by AD,')? $ billion
