About transaction frequency and the demand for money
Suppose that a household's consumption expenditure is $60,000 per year
and is financed by monthly withdrawals from a savings account.
a. Show on a graph the pattern of the household's money holding over a year.
What is the average money balance? Should we identify this average
balance with the quantity of money demanded in our model?
b. Suppose now that the frequency of withdrawals from the savings account
rises to two per month. What happens to the average money balance?
c. Return to question a., but assume now that consumption expenditure is
$120,000 per year. If withdrawls from the savings account are still
made monthly, what is the average money balance? How does this average
compare to the one in question a.? Is it optimal for the frequency of
withdrawls to remain the same when consumption expenditure increases?
Explain.
