aggregate
supply curve to the right.

firms will increase production. In the long run increased price expectations shift the short–run
aggregate
supply curve to the left.
c.

firms will decrease production. In the long run increased price expectations shift the short–run
aggregate
supply curve to the left.
16.

Refer to Figure 33-5. The appearance of the long-run aggregate-supply (LRAS) curve
a.
is consistent with the concept of monetary neutrality.
