A macroeconomic model of Econoland can be summarized as follows:
C = 100 + 0.5(Y - T)
I = 0.25 Y - 500(r)
G0 = 300
T0 = 100
X0 = 200
M0 = 200
M D = 10Y - 20,000(r)
M S0 = 200
Part a - Derive the equation for the IS Schedule
Part b - Derive the equation for the LM Schedule
Part c - Calculate the equilibrium interest rate (r)
Part d - Calculate the equilibrium level of income (Y)
