5 An economy has full employment output of 6000. Government purchases, G, are 1200. Desired consumption and investment are:Cd= 3600 - 2000r + 0.1Y and Id= 1200 -4000rwhere Y is output and ris the real saving rate.a>Find the equation relating desired national saving, Sd, to r and Y. ,
Y Cd Idand Sd Id, find the real interest rate that clears the goods market. Assume that actual output equals full employment output. G
c>Government purchases rise to 1440 at full employment output. How does this increase change the equation describing desired national saving?Show the change graphically.What happens to the market-clearing real interest rate?
