b. Is this an economy where the CB sets the money supply (exogenous) or sets the interest rates
(endogenous)? How would you represent the LM relation in equations?
c. What is the equilibrium level of income when the interest rate is 5%?
d. Solve for the equilibrium values of C and I. Now verify the value you obtained for Y by adding C, I,
and G.
