Consumption and lags.
Consider a closed-economy aggregate expenditure model where the current period's
consumption depends on the disposable income earned in the previous period; that is, we
have the following representation of the economy as:
Ct = Co + C₁YD.t-1)
YD.t = Y₂ - T₂,
1₂ = 1,
Zt = Ct + It + Gt.

Also, in equilibrium, aggregate supply equals aggregate demand, that is
Yt = Zt.
The parameters, co, I, and c₁, do not change over time and have the values co = 125, I= 50,
C₁ = 0.8.
(a) Suppose G: = T: = 125, for all t < 10. Find the steady state (where all variables are
time-independent) level of output associated with these parameter values. Assume that
the economy is at this steady state, for t < 10.
(b) At t = 10, suppose government spending increases to G: = 140, and remains at this
level forever. There is no change in taxation. Find the steady-state output associated with
this new level of government spending.
(c) Calculate the (equilibrium) values for Y₁, for t= 10, 11, 12, 13. Here you are being
asked to calculate the path from the old equilibrium to the new equilibrium.
