If government decreases its purchases by $20 billion and the MPC is 0.8, equilibrium
GDP will decrease by $100 billion.

A recessionary expenditure gap in a mixed open economy can be measured as the extent
to which aggregate expenditures (Ca + Ig + Xn + G) fall short of real GDP at the full-
employment level of real GDP.
232.
The recessionary expenditure gap is the amount by which the equilibrium GDP and the
full-employment GDP differ.
