This question examines the relationship between the Indian rupee (Rs) and the US dollar ($). We
denote the exchange rate in rupees per dollar as ERS/$. Suppose the Bank of India permanently
decreases its money supply by 4%.
1. First, consider the effect in the long run. Using the following equation, explain how the change
in India's money supply affects the Indian price level, PIN, and the exchange rate, ERS/$:
AERS/STIN

2. How does the decrease in India's money supply affect the real money supply,
in the long
PIN
run.
3. Based on your previous answer, how does the decrease in the Indian money supply affect the
nominal interest rate, UN, in the long run? (hint: M = L(i)Y hold in the long run)
4. Illustrate the graphs to show how a permanent decrease in India's money supply affects India's
money and FX markets in the long run. (hint: you may refer to the figures on lecture slides #5,

money and FX markets in the short run. (hint: you may refer to the figures on lecture slides
#5, titled Permanent Expansion of the Home Money Supply, Short-Run Impact.) How do the
nominal interest rate, IN, the spot exchange rate, ERS/$, change?
6. Compare the graphs you drew in questions 4 and 5. Describe how the short-run effects on the
nominal interest rate in, the exchange rate, ERs/$, adjust toward the long-run equilibrium?
