Trang 3BUYER BEWARE IN FINANCIAL MARKETS!
•The fraud case filed by the SEC against Goldman Sachs in 2010 highlights the important problem of asymmetric information
•In this case, asymmetric information means that Goldman Sachs, as the seller
of the Abacus collateralized debt obligations (CDOs), clearly had more
information than did the buyers

Trang 4Key Issue and Question
Here are the key issue and key question for this chapter:
Issue: During the 2007–2009 financial crisis, many economists noted
that problems in the market for bonds had the potential to deepen the
economic recession and slow the recovery because firms rely more
heavily on bonds than on stocks as a source of external finance
Question: Why do firms rely more on bonds than on stocks as a
source of external finance?
Trang 59.1 Learning Objective
Analyze the obstacles to matching savers and borrowers
Trang 6Obstacles to Matching Savers and Borrowers
Transactions costs The cost of a trade or exchange; for example, the
brokerage commission charged for buying or selling a financial asset
Information costs The costs that savers incur to determine the
creditworthiness of borrowers and to monitor how they use the funds acquired
The Problems Facing Small Investors
Trang 7• Small investors and small- to medium-sized firms turn to financial
intermediaries to meet their financial needs
• Transaction costs can be reduced by taking advantage of economies of
scale.
Economies of scale The reduction in average cost that results from an
increase in the volume of a good or service produced
How Financial Intermediaries Reduce Transactions Costs
Trang 89.2 Learning Objective
Explain the problems that adverse selection and moral hazard pose for the
financial system
Trang 9Economists distinguish between two problems arising from asymmetric
information:
Asymmetric information The situation in which one party to an economic
transaction has better information than does the other party
Moral hazard The risk that people will take actions after they have entered into a transaction that will make the other party worse off; in financial markets, the
problem investors experience in verifying that borrowers are using their funds as intended
Adverse selection The problem investors experience in distinguishing low-risk borrowers from high-risk borrowers before making an investment; in insurance, the problem that those most likely to buy insurance are also most likely to file
claims
Trang 10Adverse Selection
• The seller of a used car has more information on the true condition of a car
than does a potential buyer
• The prices that potential buyers are willing to pay reflect the buyers’ lack of
complete information on the true condition of the car
•Because of asymmetric information, the used car market adversely selects the cars that will be offered for sale
The Problems of Adverse Selection and Moral Hazard
Trang 11“Lemons Problems” in Financial Markets
• Consider a stock market example If 90% of the firms in the market are good firms and 10% are lemons, and the good firm’s share of stock is $50, then:
• So, you would be willing to pay $45.50 for a share of stock, but to a good
firm this is below the fundamental value of the stock
Trang 12• Adverse selection is present in the bond market as well.
• As interest rates on bonds rise, a larger fraction of the firms willing to pay the high interest rates are lemon firms
Credit rationing The restriction of credit by lenders such that borrowers
cannot obtain the funds they desire at the given interest rate
• When lenders ration credit, firms—whether they are good firms or lemons—
may have difficulty borrowing funds
The Problems of Adverse Selection and Moral Hazard
“Lemons Problems” in Financial Markets
Trang 13Attempts to Reduce Adverse Selection
• Disclosure of information to the SEC reduces the information costs of
adverse selection, but it doesn’t eliminate them for three reasons:
• Some good firms may be too young to have much information for potential
investors to evaluate
• Lemon firms will try to present the information in the best possible light so
that investors will overvalue their securities
• There can be legitimate differences of opinion about how to report some
items on income statements and balance sheets
Trang 14Attempts to Reduce Adverse Selection
• Private firms have collected and sold information about firms to investors to
reduce adverse selection costs
• Information is collected from sources such as firms’ income statements,
balance sheets, and investment decisions
• Individuals who gain access to the information without paying for it are free
riders
The Problems of Adverse Selection and Moral Hazard
Trang 15The Use of Collateral and Net Worth to Reduce Adverse Selection Problems
Collateral Assets that a borrower pledges to a lender that the lender may seize
if the borrower defaults on the loan
Net worth The difference between the value of a firm’s assets and the value of
its liabilities
Trang 16How Financial Intermediaries Reduce Adverse Selection Problems
The information advantage banks gain from relationship banking allows them to
reduce the costs of adverse selection and explains the key role banks play in
providing external financing to firms
Relationship banking The ability of banks to assess credit risks on the basis
of private information about borrowers
The Problems of Adverse Selection and Moral Hazard
Trang 17Making the Connection
Has Securitization Increased Adverse Selection Problems in the
Financial System?
• In the episode involving Goldman Sachs’s Abacus CDOs, one of the buyers, IKB, expected Abacus to be a good CDO According to the SEC, however, it
was designed to be a lemon
• The Abacus CDO resulted from the process of securitization, which involves
bundling loans, such as mortgages, into securities that can be sold in
financial markets
• The increase in securitization may have led to an increase in adverse
selection Securitization and the originate-to-distribute business model may
reduce banks’ incentive to distinguish between good borrowers and lemon
borrowers
Trang 18Solved Problem 9.2
Why Do Banks Ration Credit?
During the spring of 2010, an article in the Economist magazine claimed
that small businesses are not getting access to credit
a Why would banks be unwilling to make loans to small businesses?
If the banks believe some of the loans are risky, why wouldn’t they just
charge a higher interest rate to compensate for the risk?
b Does it matter that the period involved here was shortly after the end of
a deep recession?
The Problems of Adverse Selection and Moral Hazard
Trang 19Solved Problem 9.2
Why Do Banks Ration Credit?
Solving the Problem
Step 1 Review the chapter material.
Step 2 Answer part (a) by explaining how raising interest rates on loans can
increase adverse selection problems for banks.
High interest rates may attract less creditworthy borrowers A small business that is close
to declaring bankruptcy may be less concerned about having to pay a high interest rate
than would a borrower in better financial health.
Step 3 Answer part (b) by discussing whether it mattered that the period involved
was near the end of a deep recession.
During a recession, the financial health of households and firms will deteriorate, and the
number of lemon borrowers rises relative to the number of good borrowers So many
banks engaged in credit rationing by limiting the number of loans they offered rather than
increasing interest rates.
Trang 20Moral Hazard
Moral Hazard in the Stock Market
• Moral hazard arises because of asymmetric information: The borrower
knows more than the lender does about how the borrowed funds will actually
be used
• The organization of large, publicly traded corporations results in a separation
of ownership from control.
Principal–agent problem The moral hazard problem of managers (the
agents) pursuing their own interests rather than those of shareholders (the
principals)
The Problems of Adverse Selection and Moral Hazard
Trang 21Moral Hazard in the Stock Market
• Managers have an incentive to underreport profits so that they can reduce
dividends and retain the use of the funds
• To reduce this problem, the SEC requires managers to issue financial
statements
• Boards of directors meet infrequently and may not be independent of top
managers
• Some boards of directors use incentive contracts to align the goals of
managers with the goals of shareholders
• Compensation tied to the firm’s profits, however, may lead managers to
undertake risky investments
Trang 22Moral Hazard in the Bond Market
• There is less moral hazard in the bond market than in the stock market
• To reduce moral hazard in bond markets, investors insert restrictive
covenants into bond contracts.
Restrictive covenant A clause in a bond contract that places limits on the
uses of funds that a borrower receives
The Problems of Adverse Selection and Moral Hazard
Trang 23How Financial Intermediaries Reduce Moral Hazard Problems
• Financial intermediaries have evolved to fill the gap left by the
ban on banks making equity investments in nonfinancial firms.
Venture capital firm A firm that raises equity capital from investors to invest
in start-up firms
Private equity firm (or corporate restructuring firm) A firm that raises
equity capital to acquire shares in other firms to reduce free-rider and moral
hazard problems
• A market for corporate control provides a means to remove top management
Trang 24Making the Connection
Why So Many Ponzi Schemes?
• Ponzi schemes derive their name from Charles Ponzi, an Italian
immigrant who lived in Boston in the 1920s
• Ponzi schemes are an extreme form of moral hazard
• During the financial crisis of 2007–2009, the most spectacular one was
a Ponzi scheme run by Bernard Madoff
• Investors were lured by Madoff because, not only were many legitimate
investments earning high returns, but the ever increasing complexity of
financial securities made the claims of Ponzi schemes seem more
plausible

Use economic analysis to explain the structure of the U.S financial system
Trang 26Figure 9.1 Sources of External Funds to Small- to Medium-Sized Firms
Small- and sized businesses rely
medium-on loans—particularly mortgages—and trade credit as their major sources of external finance.
Conclusions about the Structure of the U.S Financial System
Trang 27Figure 9.2
External Sources of Funds to Corporations
Trang 28Three key features of the financial system:
1 Loans from financial intermediaries are the most important external
source of funds for small- to medium-sized firms.
Smaller firms cannot borrow directly from savers because transactions costs are too high; they cannot sell bonds or stocks because of the adverse selection and moral hazard problems that arise from asymmetric information
Conclusions about the Structure of the U.S Financial System
Trang 29Three key features of the financial system:
2 The stock market is a less important source of external funds to
corporations than is the bond market.
• Most of the trading on the stock market involves existing shares, not new shares of stock
• In recent years, corporations have actually bought back from investors more stock than they have issued
• Moral hazard is less of a problem with debt contracts than with equity contracts
Trang 30Three key features of the financial system:
3 Debt contracts usually require collateral or restrictive covenants.
• Large household loans use the good being purchased as collateral
• Many corporate bonds also specify collateral
• To reduce moral hazard, both loans and bonds typically contain restrictive covenants
Conclusions about the Structure of the U.S Financial System
Trang 31• By reducing transactions and information costs, financial intermediaries can
offer savers higher interest rates, offer borrowers lower interest rates, and
still earn a profit
• Commercial banks, investment banks, and other financial firms are
continually searching for ways to earn a profit by expediting the flow of funds from savers to borrowers Some of these ways involve developing new
financial securities
Trang 32Making the Connection
What Was the Problem with the Abacus CDOs?
• According to the civil fraud complaint the SEC filed against Goldman Sachs, potential purchasers of the CDO would be unknowingly buying a security
that had been constructed to fail
• The SEC argued that Goldman Sachs had an obligation to inform the other
potential investors that Paulson & Co intended to buy CDS contracts on the
CDOs after they were issued
• Goldman argued that it was not actually selling the CDOs but was instead
acting as a market maker in them
• Because the information costs of these securities are very high, they lack
transparency Goldman Sachs, in testimony before Congress, agreed that it
would be appropriate for the SEC to monitor the sale of complex securities,
such as the Abacus CDOs, more closely
Conclusions about the Structure of the U.S Financial System
Trang 33Answering the Key Question
At the beginning of this chapter, we asked the question:
“Why do firms rely more on bonds than on stocks as a source of external
finance?”
We have seen that both the bond market and the stock market are subject to
problems of moral hazard In both cases, investors have to be concerned that
firms will not use received investment funds for their intended purpose
The problem of moral hazard is considerably less serious, though, when an
investor buys a firm’s bonds than when the investor buys a firm’s stock As a
result, investors are more willing to buy bonds than stock, which explains why
bonds are a more important source of external finance for firms
Trang 34AN INSIDE LOOK AT POLICY
Ratings Downgrades Happen Too Late for Investors in Mortgage-Backed Securities
WALL STREET JOURNAL, Abacus Deal: As Bad As They Come
• Less than one year after the deal was completed, all the bonds that were
selected for Abacus 2007-AC1 were downgraded
• Ratings agencies contributed to the financial crisis by placing their highest
ratings on the Abacus deal and others like it
• The firm, Paulson & Co., specifically chose mortgage bonds that were likely
to go bad, and it bet against the deal
• Those who bought Abacus 2007-AC1 and other CDOs were the victims of
this asymmetric information
• The complexity of the deals made it difficult even for highly knowledgeable
investors to evaluate their worth
Key Points in the Article
Trang 35AN INSIDE LOOK AT POLICY
In February 2008, ratings agencies downgraded nearly all the assets (including
the 90 mortgage bonds in Abacus 2007-AC1) that were packaged to form five
CDOs
