This is the required question and it is totally complete kindly answer this all the information in given

Desired consumption is Cd=2000+0.9Y - 100,000r - G, and

desired investment is Id=1000 - 45,000r.

Real money demand is Md/P =Y - 6000i.

Other variables are inflation=0.03, G =500, Y=1000, and

M =2100.

(a) Find the equilibrium values of the real interest rate, consumption, investment, and the price level.

(b) Suppose government purchases decline to 400. What happens to the variables listed in part (a)?

(c) Suppose government purchases rise to 600. What happens to the variables listed in part (a)?

(d) What feature in this example leads to the result that you don't need to know the amount of taxes

collected by the government to find the equilibrium?
