CHAPTER 4
ANSWERS
4-1 Financial intermediaries are business organizations that receive funds in one form and repackage
4-2 Intermediaries create a variety of financial instruments for lower costs than individuals can. Without
4-3 It would be difficult for firms to raise capital. Thus, capital investment would slow down,
4-4 a. S&Ls would be better off with a "normal" yield curve. In this situation their liabilities (deposits),
which are short-term, would have a lower cost than the returns being generated by their assets
(mortgages), which are long-term. Thus they would have a positive "spread."
4-5 The financial intermediaries described in the text include:
(1) Commercial banks, which originally were established to service businesses, or commerce.
These types of institutions traditionally handled the checking function and loaned funds to
businesses.
4-6 The primary change that is evident from the deregulation of the financial services industry is that the
differences that previously existed among the various financial institutions are disappearing. Now
commercial banks offer mortgage loans while thrift institutions offer commercial loans. In addition,

no reserve requirement on nontransaction deposits. Therefore, we know the following:

b. Total deposits = Transaction deposits + Nontransaction deposits

ETHICAL DILEMMA
Anything For (a) Buc?
Ethical dilemma:
Mr. Charles, the CEO of the Bank of Universal City (BUC), is concerned that the company’s growth this
year will be below what is needed to achieve growth projections during the next five years. Mr. Charles
believes that Univest, the investment management division of BUC, can increase its sales so that the
entire organization can meet the projected growth for the year and keep the firm on track to meet its
future growth expectations. To help, Mr. Charles has given the VP of Univest, who is your boss, some
“leads” to contact for possible new accounts. One of the most promising leads is a religious organization
with a shady reputation—Righteous Freedom Choice (RFC). It has been rumored that RFC is involved,
either directly or indirectly, in unsavory activities, including sponsoring terrorism in other parts of the
world, and the funds it receives come from organizations involved in similar illicit activities. Although the
rumors are just that—rumors—there are indications that they might be true. A colleague of yours
provided you with much of this information, which was relayed to her by a couple of prominent
businesspersons. The validity of the information is questionable, however, because the persons who
provided the information are not on friendly terms with the head of RFC, Mr. Radcliff. Should BUC
pursue RFC as a potential customer? It appears that RFC will be moving its funds to a new investment
management firms soon. Even if the rumors prove to be correct, is there a problem with BUC managing
RFC’s money?

Discussion questions:

In this case, it appears that the ethical dilemma is whether it is appropriate to do business with

If RFC is involved in unethical activities and BUC gets its business, other customers might take their
• What decision should BUC make?
Ask the students what they would do if they were the assistant to the vice president in charge of
Univest. Undoubtedly, students will argue for one of two decisions: (1) Try to attract RFC as a customer,
or (2) stay away from RFC. If the rumors relayed to “you” (the vice president’s assistant) by a colleague
