9: Multiple Choice
Why does the short-run aggregate supply curve shift to the left in the long run, following an increase in
aggregate demand?
(a) Workers and firms adjust their expectations of wages and prices downward and they accept lower
wages and prices.
(b) Workers and firms adjust their expectations of wages and prices downward and they push for higher
wages and prices.
(c) Workers and firms adjust their expectations of wages and prices upward and they push for higher
wages and prices.
(d) Workers and firms adjust their expectations of wages and prices upward and they accept lower wages
and prices.
10: Multiple Choice
Workers expect inflation to fall from 4% to 1% next year. As a result, this should

(b) shift the short-run aggregate supply curve to the right.
(c) move the economy up along a stationary short-run aggregate supply curve.
(d) move the economy down along a stationary short-run aggregate supply curve.
11: Multiple Choice

will rise.
(b) Aggregate demand will rise, the equilibrium price level will fall, and the equilibrium level of GDP will
rise.
