Refer to Figure 2 in the Appendix and assume that Q 1 is

$400 and Q 2 is $500, the price level is stuck at P 1 , and the slopes of the AE lines in Figure 2a are .75 and equal to the MPC. In what direction and by how much does the aggregate expenditures schedule in Figure 2a need to shift to move the aggregate demand curve in Figure 2b from AD 1 to AD 2 ?

What is the multiplier in this example? Given the multiplier, what must be the distance between AD 1 and the broken line to its right at P 1 ? LO5
