Consider a goods market in the following situation.
(1) Aggregate demand: Z=C+I+G
(2) Aggregate supply: Y=Z
(3) C(Consumption)=c0+c1(Y-T),
(4) G(government spending)= g0-g1Y, T(government tax revenue)=
t0+t1Y (all the
coefficients are non-negative),
(5) (Exogenously given) I=investment
(a) Give interpretations on the newly introduced functions of
the government spending
and revenue. Do they seem realistic?
(b) Represent
Y∗
as a function of exogenous variables and parameters.
(c) Assess the effects of changes in g1 on
Y∗
.
(d) Assess the effects of changes in t1 on
Y∗
. What is the meaning of t1?
