FIGURE 9-9 The aggregate expenditures domestic output approach to equilibrium GDP. The
aggregate expenditures schedule, C1 Ig, is determined by adding the investment schedule Ig
to the upsloping consumption schedule C. Since investment is assumed to be the same at
each level of GDP, the vertical distances between C and C 1 Ig do not change. Equilibrium
GDP is determined where the aggregate expenditures schedule intersects the 45 degree line,
in this case at $470 billion. |

In this figure, the slope of the aggregate expenditures schedule C + Ig:
