6. LR Classical Model: Given the following functions: Consumption function is given by C: 1700+ .7 (YT) The tax function is given by T: 200 + tY , i.e., we now include a simple at income tax in the model. Investment demand is given by l(r) = 1600-25r G = 3800 Y = 15000 (note: these are in $ billions and the interest rate given is solved in percent). Show all formulas and calculations: a. Assume a simplified at income tax rate of 23 percent. Using the long run classical model, what is aggregate personal consumption, the equilibrium real interest rate, and gross domestic private investment and total factor income
