1. Use the following information from a fictional economy:
Consumption, C = 250 + 0.8 Yd
Investment, I = 200
Government Spending, G = 100
Taxes, T = 0.2 Y
Net Exports, NX = 50 - 0.4 Y
Disposable Income, Yd = Y-T
%3D
Real GDP = Y

(a) What is equilibrium Real GDP (Y) for this economy?
(b) What is equilibrium C for this economy?
(c) What is equilibrium NX for this economy?
(d) What is equilibrium T for this economy?
(e) What is equilibrium YD for this economy?
6. Consider the following economy: C= 100+0.8Y, I = 200, G = 125, NX= 75. (a) Compute the
equilibrium GDP
(b) If the government decides to increase the spending by $30, how much will be the impact
on equilibrium GDP? (Hint: Spending multiplier = 1/1 - MPC)
1. (a) The following equations describe an economy:
C-100+ 0.75Yd
I-50-25r
T-G-50
Where C is aggregate consumption, Y is disposable income, I is aggregate investment. I is
taxes, G is government purchases and r is the rate of interest. Derive the IS curve for the
economy. Show the area of excess demand and excess supply in the goods market.
(b) Draw the graph and explain the derivation of IS curve.
2. (a) Given the following data about the monetary sector of the economy:
Ma -0.4Y-80r
M₁ - 1200 million
Where, Ma is demand for money, Y is the level of income, r is the rate of interest and
M, is the supply of money.
Derive the equation for LM curve and give the economic interpretation of this curve.
Show the excess demand and excess supply in the money market.
(b) Draw the graph and explain the derivation of LM curve.

- (Use for a and b)Suppose the interest on the debt was $700 billion. If interest is paid domestically, 90% will be spent domestically (the remainder is spent on foreign goods). If interest is paid to the foreign sector, only 10% is spent here (the remainder is spent in foreign countries). Every dollar collected in taxes to pay the interest causes domestic spending to fall 90 cents.
