考虑下列式子描述的一个经济体的情况:
Y=C+I+G
Y=5000
G=1000
T=1000
C=250+0.75(Y-T)
I=1000-50r
a.在这一经济中,计算私人储蓄、公共储蓄和国民储蓄。
b.找出均衡利率。
c.现在假设G增加到1250。计算私人储蓄、公共储蓄以及国民储蓄。
d.找出新的均衡利率。
Consider an economy described by the following equations:
Y=C+I+G
Y=5,000
G=1,000
T=1,000
C=250+0.75(Y-T)
I=1,000-50r
a.In this economy, compute private saving, public saving, and national saving.
b.Find the equilibrium interest rate.
c.Now suppose that G rises to 1,250. Compute private saving, public saving, and national saving.
