sugar is purchased by households.

Sweaters

Soft drinks

a. Calculate nominal GDP for this simple economy.

(See more on PROBLEMS AND APPLICATIONS: Questions 5, 6, 7, 9 (chapter 23), Questions 2, 3, 5, 7 (chapter 24)
Inflation rate = 20%
Nominal income is 40 in 2018 and 60 in 2019.
=>% change in nominal income =
% change real income = % change in nominal income - % change prices = 50% - 20% = 30%.

Question 3 (2 marks):
7
a. Use a loanable funds diagram to analyze the impact of an increase in government deficit on the interest rate,
investment and national saving.
Supply = Savings (Sp + Sg), Sp = Yd – Tax, Sg = Tax - G; Demand = Investment
b. The banking system has $10 million in reserves, the reserve requirement is 10 percent. The public holds no
cash. Assume that the central bank purchases $3 million government bonds in open market operations and
there are no excess reserves. Calculate the change in money supply resulted from the above policy and
show its effects on interest rates and money quantity in the money market diagram.

Question 4 (2 marks): Assume the economy is initially in a long run equilibrium.
a. Use the AD-AS and the Philips curve diagrams to show the short-run effects on prices (inflation) and
output (unemployment) if central bank buys government bonds in the open market operations.
AD = C(Y-T, r) + I(r) + G + NX(e,p/p*, tariff, taste,…)
AS = F(K, L, H, T, R, production costs, expected)
central bank buys government bonds in the open market operations → Ms increases → r decreases → C and
I increase → AD increase, AD curve shifts to the right.
