Question

Please help with this from c and d. Please make it make sense because I have seen answers that dont seem right. With graphs as well if you can for the two.
Consider an economy described by the following equations:
Y=C + I +G
Y=7,000
G=4000
T=2,000
C=150+0.75(Y-T)
I=1,000-50r
a. In this economy, compute private saving, public saving and national saving.
b. Calculate the equilibrium interest rate.
c. Now suppose the G rises by 1,000. Compute private saving, public saving, and
national saving.
d. Calculate the new equilibrium interest rate.

Expert Solution
Step 1

Dear Student as you have asked for solution of Part C and D only, kindly find the images attached for detailed solution. Remember that G rises by 1000 for this part so it will add in the initial G which was 4000. New G will become:- 4000+1000=5000.
