8. Economic fluctuations I
The following graph shows the economy in long-run equilibrium at the expected price level of 120
and the natural level of output of $600 billion. Suppose the government increases spending on
building and repairing highways, bridges, and ports.
Shift the short-run aggregate supply (AS) curve or the aggregate demand (AD) curve to show the
short-run impact of the increase in government spending.
