closed economy described by the following equations 5000 G 1000 = 1 000 C- 100+0.75(Y – T) ?-1000-10r where Y is total income (GDP), G is the government expenditure, T are the taxes, C is aggregate consumption that depends on disposable income (Y-T) and I is the investment function that we assume to be negatively related with the interest rate (r). a) From this economy, calculate private, public and national saving; b) Use the income expenditure identity to calculate the equilibrium interest rate; c) Now suppose that G increases to 1500, everything else constant. Calculate the private, public and national saving in this case; d) Find the new equilibrium interest rate.
