Problem 4. In a closed economy, consumption is C = 100+0.8Yp – 50r, taxes T = 200 and transfers are TR=100. The investment function is I = 530 – 10,000r. Output is Y = 1000. Public debt is zero. (A) Find government spending G if the government budget is balanced. (B) Derive the total savings function S(r). Do savings depend on the interest rate? If yes, positively or negatively? Why? Give economic reasoning. (C) Find the equilibrium on the loanable funds market: find, at equilibrium, r, S and I.

530 – 10,000r. Output is Y = 1000. Public debt is zero.
TR= 100. The investment function is I =
(A) Find government spending G if the government budget is balanced.
(B) Derive the total savings function S(r). Do savings depend on the interest rate? If yes, positively or
negatively? Why? Give economic reasoning.
(C) Find the equilibrium on the loanable funds market: find, at equilibrium, r, S and I.
(D) The government raises its spending by 150 and finances this by borrowing. Find the new equilibrium.
Does the crowding out effect takes place? If yes, describe it in detail: what crowds out what. If not,
explain why.
(E) Instead, the government raises its spending by the same 150 and finances this by raising taxes by
an equal amount (to keep the budget balanced). Find the new equilibrium. Does the crowding out
effect takes place? If yes, describe it in detail: what crowds out what. If not, explain why.
(F) Draw the loanable funds market diagram. Show the initial equilibrium and the two equilibria under
the two fiscal policies.
