The Economics of Financial Intermediation
Chapter Overview
In theory, the market system may seem neat and simple, but in reality economic growth is
a messy, chaotic thing. Problems with the flow of information between parties in a
market system can derail economic growth unless they are addressed properly. This
chapter discusses some of those information problems and the ways that financial
intermediaries attempt to solve them.
Learning Objectives: Establish an understanding of:
1. How intermediaries promote efficiency
2. The central role of information costs
3. Incentive problems in finance
Important Points of the Chapter
Economic well-being is inextricably tied to the health of the financial intermediaries that
make up the financial system. These institutions pool funds from people and firms who
save and lend them to people and firms that need to borrow, and when they do their job
correctly, investment and economic growth increase at the same time that investment risk
and economic volatility decrease. There is a strong link between financial development
and economic development; without a stable, well-functioning financial system, no
country can prosper.
Application of Core Principles
Principle #4: Markets. Financial intermediaries provide access to the payments system
and so facilitate the exchange of goods and services, promoting specialization.
Moreover, reducing the cost of financial transactions also promotes more trade and
specialization.
Principle #2: Risk. Banks mitigate risk by taking deposits from a large number of
individuals and make thousands of loans with them, thus giving each depositor a small
stake in each of the loans.
Principle #2: Risk. Risk requires compensation, and in the bond market this means that
the higher the risk, the greater the risk premium. If a lender can’t tell whether a borrower
is a good or bad credit risk, the lender will demand a risk premium based on the average
risk. The good borrowers are likely to withdraw from the market rather than pay the high
rate, and only the bad borrowers will be left.

Teaching Tips/Student Stumbling Blocks
To emphasize the five functions performed by financial intermediaries (i.e., they
pool the resources of small savers; they provide safekeeping and accounting
services as well as access to the payments system; they supply liquidity; they
provide ways to diversify small investments (reducing their risk); and they collect
and process information in ways that reduce information costs) have students list
the various financial intermediaries with which they do business. Which
function(s) are performed by each?
Have students consider the factors that might affect their credit scores. Students
may not realize that a credit card with no balance but which has a credit amount is
treated exactly as if that amount was owed; this is a good example of how a lender
deals with moral hazard (i.e., the borrower could go out tomorrow and charge that
amount to the credit card). On the other hand, lenders also look at how much of
the total credit a person has is “available.”
Features in this Chapter
Your Financial World: Your First Credit Card
The interest rate on your first credit card is likely to be very high because you have no
credit history, and the company issuing the card will assume the worst. This is adverse
selection at its worst. After a while, when you establish a track record, you should be
able to get a card at a lower rate.
Applying the Concept: The Madoff Scandal
The fraud perpetrated by Bernard Madoff stands out as extraordinary, though it was an
ordinary Ponzi scheme. Why do such schemes work? They work for a number of
reasons, including investors failing to screen and monitor the managers of their
investments, and public respectability of those managers. Further, sometimes the
government agencies responsible for overseeing the managers fail to detect the scheme.
Your Financial World: Private Mortgage Insurance
If you try to buy a house with a down payment of less than 20 percent of the purchase
price, the lender may require you to buy private mortgage insurance (PMI), which insures
the lender in the event that the borrower defaults on the mortgage. You can cancel the
insurance when the amount you owe on your mortgage falls to less than 80 percent of the
value of your home; this can happen as a result of your making payments to reduce the
principal on the loan or as a result of increases in home values.

Applying the Concept: Deflation, Net Worth, and Information Costs
Deflation is bad because it aggravates information problems in ways that inflation does
not. It means that a firm’s net worth goes down as a result of drops in asset values,
making it less trustworthy as a borrower. This is what occurs at the start of a recession:
the value of the firm falls, lenders become more reluctant to lend, and the availability of
investment funds falls, pushing the economy further into the recession.
Lessons from the Crisis: Information Asymmetry and Securitization
A key source of the financial crisis of 2007-2009 was insufficient screening and
monitoring in the securitization of mortgages. These problems began with the loan
originators who eased standards and reduced screening to increase the volume of lending
and their own profitability. The distributors—the next stage of lending that assembled
these loans into securities—did little to forestall the decreased standards although they
could have had higher requirements. The securitization then resulted in frequent trading
to get rid of the security before it defaulted. Rating agencies continued the problem by
awarding high ratings to MBSs and investors relied on others opinions of the securities.
Had housing prices continued to increase, this collateral system would have worked.
In the News: China Shadow Bankers Go Online as Peer-to-Peer Sites Boom
Peer-to-peer lending is increasing in China as traditional methods of private lending
among family and friends moves online. China’s peer-to-peer lenders let individuals
invest a minimum of 50 yuan in projects for as much as 23 percent interest, the highest
rate allowed by law.
Lessons of the Article: Will peertopeer lending sites grow enough to offer
serious competition to banks and other financial intermediaries? Not unless they
can likewise expand lenders’ ability to screen and monitor borrowers to
minimize the problems of adverse selection and moral hazard. With only
rudimentary screening by peertopeer lenders, only the borrowers know the
risks of the loans.
Additional Teaching Tools
In an article from the Wall Street Journal, Jane Kim discusses the appealing switch from
banks to credit unions. Benefits include higher interest rates on deposits, lower fees, and
lower rates on borrowing.

For More Discussion
Have students consider a transaction like selling a car or a house; you may wish to do this
as a role-playing exercise. Students are likely to quickly discover that they need
information about whether a potential buyer actually has the resources to complete the
transaction.
Here’s another topic for discussion: have students consider whether they would buy a
used car from a person or from a dealership. What are the pros and cons of each and how
does that relate to the chapter material?
Chapter Outline
I. The Role of Financial Intermediaries
1. As a general rule, indirect finance through financial intermediaries is much
more important than direct finance through the stock and bond markets.
2. In virtually every country for which we have comprehensive data, credit
extended by financial intermediaries is larger as a percentage of GDP than
stocks and bonds combined.

Chapter 11 – The Economics of Financial Intermediation
3. Around the world, firms and individuals draw their financing primarily from
banks and other financial intermediaries.
4. The reason for this is information; financial intermediaries exist so that
individual lenders don’t have to worry about getting answers to all of the
important questions concerning a loan and a borrower.
5. Lending and borrowing involve transactions costs and information costs, and
financial intermediaries exist to reduce these costs.
6. Financial intermediaries perform five functions: they pool the resources of
small savers; they provide safekeeping and accounting services as well as
access to the payments system; they supply liquidity; they provide ways to
diversify small investments; and they collect and process information in ways
that reduce information costs.
7. The first four of these functions have to do with the reduction of transactions
costs.
8. International banks handle transactions that cross borders, which may mean
converting currencies.
Pooling Savings
1. The most straightforward economic function of a financial intermediary is to
pool the resources of many small savers.
2. To succeed in this endeavor the intermediary must attract substantial numbers
of savers.
3. This is the essence of indirect finance, and it means convincing potential
depositors of the soundness of the institution.
4. Banks rely on their reputations and government guarantees like deposit
insurance to make sure customers feel that their funds will be safe.
B. Safekeeping, Payments System Access, and Accounting
1. Goldsmiths were the original bankers; people asked the goldsmiths to store
gold in their vaults in return for a receipt to prove it was there.
2. People soon realized that trading the receipts was easier than trading the gold
itself.
3. Eventually the goldsmiths noticed that there was gold left in the vaults at the
end of the day, so it could safely be lent to others.
4. Today, banks are the places where we put things for safekeeping; we deposit
our paychecks and entrust our savings to a bank or other financial institution
because we believe it will keep our resources safe until we need them.
5. Banks also provide other services, like ATMs, checkbooks, and monthly
statements, giving people access to the payments system.

Chapter 11 – The Economics of Financial Intermediation
6. Financial intermediaries also reduce the cost of transactions and so promote
specialization and trade, helping the economy to function more efficiently.
7. The bookkeeping and accounting services that financial intermediaries
provide help us to manage our finances.
8. Providing safekeeping and accounting services as well as access to the
payments system forces financial intermediaries to write legal contracts,
which are standardized.
9. Much of what financial intermediaries do takes advantage of economies of
scale, which means that the average cost of producing a good or service falls
as the quantity produced increases.
10. Information is also subject to economies of scale.
C. Providing Liquidity
1. One function that is related to access to the payments system is the provision
of liquidity.
2. Liquidity is a measure of the ease and cost with which an asset can be turned
into a means of payment.
3. Financial intermediaries offer us the ability to transform assets into money at
relatively low cost (ATMs are an example).
4. Financial intermediaries provide liquidity in a way that is both efficient and
beneficial to all of us.
5. By collecting funds from a large number of small investors, a bank can reduce
the cost of their combined investment, offering the individual investor both
liquidity and high rates of return.
6. Financial intermediaries offer depositors something they can’t get from the
financial markets on their own.
7. Financial intermediaries offer both individuals and businesses lines of credit,
which are pre-approved loans that can be drawn on whenever a customer
needs funds.
D. Diversifying Risk
1. Financial intermediaries enable us to diversify our investments and reduce
risk.
2. Banks mitigate risk by taking deposits from a large number of individuals and
make thousands of loans with them, thus giving each depositor a small stake
in each of the loans.
3. Providing a low-cost way for individuals to diversify their investments is a
function all financial intermediaries perform.

Chapter 11 – The Economics of Financial Intermediation
E. Collecting Processing Information
1. One of the biggest problems individual savers face is figuring out which
potential borrowers are trustworthy and which are not.
2. There is an information asymmetry because the borrower knows whether or
not he or she is trustworthy, but the lender faces substantial costs to obtain the
same information.
3. Financial intermediaries reduce the problems created by information
asymmetries by collecting and processing standardized information.
II. Information Asymmetries and Information Costs
1. Information plays a central role in the structure of financial markets and
financial institutions.
2. Markets require sophisticated information in order to work well, and when the
cost of obtaining information is too high, markets cease to function.
3. Asymmetric information is a serious hindrance to the operation of financial
markets, and solving this problem is one key to making our financial system
work as well as it does.
4. Asymmetric information poses two obstacles to the smooth flow of funds
from savers to investors: adverse selection, which involves being able to
distinguish good credit risks from bad before the transaction; and moral
hazard, which arises after the transaction and involves finding out whether
borrowers will use the proceeds of a loan as they claim they will.
A. Adverse Selection
1. Used Cars and the Market for Lemons: In a market in which there are good
cars (“peaches”) and bad cars (“lemons”) for sale, buyers are willing to pay
only the average value of all the cars in the market. This is less than the
sellers of the “peaches” want, so those cars disappear from the markets and
only the “lemons” are left.
a. To solve this problem caused by asymmetric information, companies like
Consumer Reports provide information about the reliability and safety of
different models, and car dealers will certify the used cars they sell.
2. Adverse Selection in Financial Markets: Information asymmetries can drive
good stocks and bonds out of the financial market.
B. Solving the Adverse Selection Problem
1. Disclosure of Information: Generating more information is one obvious way
to solve the problem created by asymmetric information.
a. This can be done through government required disclosure and the private
collection and production of information.

Chapter 11 – The Economics of Financial Intermediation
b. However, the accounting scandals of 2001 and 2002 showed that in spite
of such requirements companies can distort the profits and debt levels
published in their financial statements.
c. Reports from private sources such as Moody’s and Value Line are often
expensive.
2. Collateral and Net Worth: Lenders can be compensated even if borrowers
default, and if the loan is so insured then the borrower is not a bad credit risk.
a. The importance of net worth in reducing adverse selection is the reason
owners of new businesses have so much difficulty borrowing money.
C. Moral Hazard: Problem and Solutions
1. An insurance policy changes the behavior of the person who is insured.
2. Moral hazard plagues both equity and bond financing.
3. Moral Hazard in Equity Financing: people who invest in a company by
buying its stock do not know that the funds will be invested in their best
interests.
a. The principal-agent problem, which occurs when owners and managers
are separate people with different interests, may result in the funds not
being used in the best interests of the owners.
4. Solving the Moral Hazard Problem in Equity Financing: The problem can be
solved by if owners can fire managers and by requiring managers to own a
significant stake in their own firm.
5. Moral Hazard in Debt Finance: Debt goes a long way toward eliminating the
moral hazard problem, but it doesn’t finish the job; debt contracts allow
owners to keep all the profits in excess of the loan payments and so encourage
risk taking.
6. Solving the Moral Hazard Problem in Debt Finance: To some degree, a good
legal contract with restrictive covenants can solve the moral hazard problem
in debt finance.
III. Financial Intermediaries and Information Costs
A. Screening and Certifying to Reduce Adverse Selection
1. Borrowers must fill out a loan application that includes information that can
be provided to a company that collects and analyzes credit information and
which provides a summary in the form of a credit score.
2. Your personal credit score tells a lender how likely you are to repay a loan; the
higher your score the more likely you are to get a loan.
3. Banks collect additional information about borrowers because they can
observe the pattern of deposits and withdrawals, as well as the use of credit
and debit cards.

Chapter 11 – The Economics of Financial Intermediation
4. Financial intermediaries’ superior ability to screen and certify borrowers
extends beyond loan making to the issuance of bonds and equity.
5. Underwriting represents screening and certifying because investors feel that if
a well-known investment bank is willing to sell a bond or stock then it must
be a high-quality investment.
B. Monitoring to Reduce Moral Hazard
1. Intermediaries monitor both the firms that issue bonds and those that issue
stocks.
2. Banks will monitor borrowers to make sure that the funds are being used as
intended.
3. Financial intermediaries that hold shares in individual firms monitor their
activities, in some cases placing a representative on a company’s board of
directors.
4. In the case of new firms, a financial intermediary called a venture capital firm
does the monitoring.
5. The threat of a takeover helps to persuade managers to act in the interest of
the stock and bondholders.
6. In the end, the vast majority of firm finance comes from internal sources,
suggesting that information problems are problems too big for even financial
intermediaries to solve.

Chapter 11 – The Economics of Financial Intermediation
Lessons of Chapter 11
1. Financial intermediaries specialize in reducing costs by
a. Pooling the resources of small savers and lending them to large borrowers.
b. Providing safekeeping, accounting services, and access to the payments system.
c. Providing liquidity services.
d. Providing the ability to diversify small investments.
e. Providing information services.
2. For potential lenders, investigating a borrower’s trustworthiness is costly. This
problem, known as asymmetric information, occurs both before and after a
transaction.
a. Before a transaction, the least creditworthy borrowers are the ones most likely to
apply for funds. This problem is known as adverse selection.
b. Lenders and investors can reduce adverse selection by
i. Collecting and disclosing information on borrowers.
ii. Requiring borrowers to post collateral and show sufficient net worth.
c. After a transaction, a borrower may not use the borrowed funds as productively as
possible. This problem is known as moral hazard.
i. In equity markets, moral hazard exists when the managers’ interests
diverge from the owners’ interests.
ii. Finding solutions to the moral hazard problem in equity financing is
difficult.
iii. In debt markets, moral hazard exists because borrowers have limited
liability. They get the benefits when a risky bet pays off, but they don’t
suffer a loss when it doesn’t.
iv. The fact that debt financing gives managers/borrowers an incentive to take
too many risks gives rise to restrictive covenants, which require borrowers
to use funds in specific ways.
3. Financial intermediaries can solve the problems of adverse selection and moral
hazard.
a. They can reduce adverse selection by collecting information on borrowers and
screening them to check their creditworthiness.
b. They can reduce moral hazard by monitoring what borrowers are doing with
borrowed funds.
c. In the end, the vast majority of firms’ finance comes from internal sources,
suggesting that information problems are too big for even financial intermediaries
to solve.
