Suppose that a person's yearly income is b60 000. Also suppose that this person's money demand function is given by

Md = aY(0.30 i)

a. What is this person's demand for money when the interest rate is 5%? 10%?

b. Explain how the interest rate affects money demand.

c. Suppose that the interest rate is 10%. In percentage

terms, what happens to this person's demand for money

if her yearly income is reduced by 50%?

d. Suppose that the interest rate is 5%. In percentage terms,

what happens to this person's demand for money if her

yearly income is reduced by 50%?

e. Summarise the effect of income on money demand. In

percentage terms, how does this effect depend on the

interest rate?
