Development Partners Housing has been practicing cash management
for some time by using the Baumol model for determining cash
balances. Some time ago, the model called for an average balance
(C*/2) of $500; at that time, the rate on marketable securities was
4.0 percent. A rapid increase in interest rates has driven the
interest rate up to 9.0 percent. What is the appropriate average
cash balance now? Note that the fixed cost per transaction and the
total cash needed for transactions during the year did not change.
