Macroeconomics
For any developing country, analyze its exchange rate system and all recent developments in its exchange rate policies. Use these to answer the following questions in your writing:
What are monetary and fiscal policy implications of the exchange rate system adapted by the selected country?
What is the devaluation history (dates) of the selected country? Have past devaluations achieved the targeted economic objectives?
How trade has performed in the selected country post-devaluation?
What are your views on ensuring better BOP-NIIP outcomes of this country?
After searching the history of exchange rate regime in your selected country, you explain conceptually about efficacy of each exchange rate system (fixed, floating and pegged) and its implication on monetary policy and fiscal policy. Next discussion should be on devaluation, its objectives and situation analysis post devaluation. Answer all questions above.

Suppose that the following system of equations describe the macroeconomy of a
hypothetical country:
Y= C(y)+I(i)+G : IS or goods market
M/p=L(i,y) : LM or money market
a) Get the total differentials of the above system of equations and put your answer
in matrix representation.
b) Taking money supply and government expenditure as exogenous and the price
level as fixed, determine and provide economic intuition for the signs and
magnitudes of the following multipliers
i)
dY/dG
ii)
di/dG
c) For a simultaneous increase in both the interest elasticity of investment and
interest elasticity demand for money parameters, determine the net effect on the
values of the multipliers in part b).
d) For a horizontal LM curve, determine the numerical values of your answers in
part b) above if:
Marginal propensity to consume=5/6
Tax rate=0.25
Interest elasticity of investment=5
Interest elasticity of demand for money=50
Income elasticity of demand for money=2

Autonomous investment=1000
Autonomous taxes=100
Autonomous government expenditure=400
Real money supply (M/P)=600
Tax rate=0.25
Marginal propensity to consume=0.8

A) Assume a GHȼ450 million increase in government expenditure is financed by a
GHȼ300 million increase in taxes and GHȼ150 increase in money supply. Without
deriving the IS-LM equations, find the new equilibrium income and interest rate.
Explain.
B) If government wants equilibrium income and interest rate increased by 1400 and
0.8 units respectively:
i.
Determine how much government expenditure and money supply should
be changed to achieve these targets.
ii.
Determine how much autonomous taxes expenditure and money supply
should be changed to achieve these targets.

a) Find λ1, λ2, β1, β2. Determine and explain the relative effectiveness of fiscal and
monetary policies.
b) Use your answer in part a) above to determine equilibrium income and interest rate.
c) State the values of the fiscal and monetary policy multipliers if the economy is in a
liquidity trap. Explain.

rate and equilibrium income will change. Can you determine the extent to which
investment is crowded out as a result? Explain.

In the classical model, an autonomous decline in investment leads to a fall in the overall
demand in the economy. Explain, with the help of a diagram, whether you agree or disagree.

Iñigo divides his income between banana and bread. A typhoon damaged banana plantations causing a large increase in the price of bananas.
1.Show the effect of the typhoon on Iñigo’s budget constraint.
2.Show the effect of the typhoon on Iñigo’s optimal consumption bundle assuming that the substitution effect has the same extent of effect with income effect.
3.Show the effect of the typhoon on Iñigo’s optimal consumption bundle assuming that the income effect outweighs or dominates the substitution effect for bread.
