Suppose an unanticipated increase in investment spending causes the aggregate demand curve to shift to the right (from AD1₁ to AD₂). According to
adherents of the adaptive-expectations theory, the unanticipated change in aggregate demand will cause the economy to move in which direction?
O From point N to point K, before returning to point N
O From point N to point D and, eventually, from point D to point Z
O Directly from point N to point Z
O From point N to point D, before returning to point N
Now suppose that the increase in investment spending was entirely anticipated by firms and workers. This means the public fully anticipates the rightward
shift of the aggregate demand curve (from AD₁ to AD₂). According to rational-expectations adherents, the anticipated change in aggregate demand will
cause the economy to move in which direction?
O From point N to point K, before returning to point N
Directly from point N to point Z
O From point N to point D, before returning to point N
O From point N to point D and, eventually, from point D to point Z
