Why Study Money, Banking, and Financial Markets?
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-2
Why Study Money, Banking, and Financial Markets• To examine how financial markets such as bond and
stock markets work
• To examine how banks, other financial institutions and financial regulation work
• To examine the role of monetary policy in the economy
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-3
Financial Markets
• Markets in which funds are transferred from people who have an excess of available funds to people who have a shortage of funds
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-4
The Bond Market and Interest Rates• A security (financial instrument) is a claim on the
issuer’s future income or assets
• A bond is a debt security that promises to make payments periodically for a specified period of time (that is, IOU)
• An interest rate is the cost of borrowing or the price paid for the rental of funds

The Stock Market
• Common stock represents a share of ownership in a corporation (IOBU)
• A share of stock is a claim on the earnings and assets of the corporation
• Common stock holders are residual claimants.

Financial Institutions and Banking• Financial Intermediaries: institutions that borrow
funds from people who have saved and make loans to other people:– Banks: accept deposits and make loans
– Other Financial Institutions: insurance companies, finance companies, pension funds, mutual funds and investment banks
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-9
Financial Crises
• Financial crises are major disruptions in financial markets that are characterized by sharp declines in asset prices and the failures of many financial and nonfinancial firms.
• Severe financial crises typically spill over into the real economy.
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-10
Function of Financial Markets1. Allows transfers of funds from person or business without investment opportunities to one who has them2.Improves economic efficiency3.Transfer funds over life horizon
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-11
Direct and Indirect Finance
• Direct finance: lenders hold direct claims on borrowers’ assets or future income.
• Indirect finance: Lenders hold claims on financial intermediary, which in turn hold claims on borrowers. (q)

Relation of Liquidity PreferenceFramework to Loanable FundsKeynes’s Major AssumptionTwo Categories of Assets in Wealth
MoneyBonds
1. Thus: Ms + Bs = Wealth2. Budget Constraint: Bd + Md = Wealth3. Therefore: Ms + Bs = Bd + Md
4. Subtracting Md and Bs from both sides:Ms – Md = Bd – Bs
Money Market Equilibrium5. Occurs when Md = Ms
6. Then Md – Ms = 0 which implies that Bd – Bs = 0, so that Bd = Bs and bond market is also in equilibrium
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-37
1. Equating supply and demand for bonds as in loanable funds framework is equivalent to equating supply and demand for money as in liquidity preference framework
2. Two frameworks are closely linked, but differ in practice because liquidity preference assumes only two assets, money and bonds, and ignores effects on interest rates from changes in expected returns on real assets

Liquidity Preference AnalysisDerivation of Demand Curve1. Keynes assumed money has i = 02. As i , relative RETe on money (equivalently, opportunity cost of
money ) Md 3. Demand curve for money has usual downward slopeDerivation of Supply curve1. Assume that central bank controls Ms and it is a fixed amount2. Ms curve is vertical lineMarket Equilibrium1. Occurs when Md = Ms, at i* = 15%2. If i = 25%, Ms > Md (excess supply): Price of bonds , i to i* =
15%3. If i =5%, Md > Ms (excess demand): Price of bonds , i to
i* = 15%

Risk Structure of Interest Rates• Bonds with the same maturity have different
interest rates due to:– Default risk– Liquidity – Tax considerations
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-49
Risk Structure of Interest Rates• Default risk: probability that the issuer of
the bond is unable or unwilling to make interest payments or pay off the face value– U.S. Treasury bonds are considered default free
(government can raise taxes). – Risk premium: the spread between the interest
rates on bonds with default risk and the interest rates on (same maturity) Treasury bonds

Risk Structure of Interest Rates• Liquidity: the relative ease with which an
asset can be converted into cash– Cost of selling a bond– Number of buyers/sellers in a bond market
• Income tax considerations– Interest payments on municipal bonds are
exempt from federal income taxes.

FIGURE 3 Interest Rates on Municipal and Treasury Bonds
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-54
Term Structure of Interest Rates• Bonds with identical risk, liquidity, and tax
characteristics may have different interest rates because the time remaining to maturity is different
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-55
Term Structure of Interest Rates• Yield curve: a plot of the yield on bonds with
differing terms to maturity but the same risk, liquidity and tax considerations– Upward-sloping: long-term rates are above
short-term rates– Flat: short- and long-term rates are the same– Inverted: long-term rates are below short-term
rates
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-56
Facts Theory of the Term Structure of Interest Rates Must Explain
1. Interest rates on bonds of different maturities move together over time
2. When short-term interest rates are low, yield curves are more likely to have an upward slope; when short-term rates are high, yield curves are more likely to slope downward and be inverted
3. Yield curves almost always slope upward
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-57
Three Theories to Explain the Three Facts1. Expectations theory explains the first two
facts but not the third2. Segmented markets theory explains fact
three but not the first two3. Liquidity premium theory combines the
two theories to explain all three facts

Expectations Theory
• The interest rate on a long-term bond will equal an average of the short-term interest rates that people expect to occur over the life of the long-term bond
• Buyers of bonds do not prefer bonds of one maturity over another; they will not hold any quantity of a bond if its expected return is less than that of another bond with a different maturity
• Bond holders consider bonds with different maturities to be perfect substitutes
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-60
Expectations Theory: Example• Let the current rate on one-year bond be
6%.• You expect the interest rate on a one-year
bond to be 8% next year.• Then the expected return for buying two
one-year bonds averages (6% + 8%)/2 = 7%.
• The interest rate on a two-year bond must be 7% for you to be willing to purchase it.

Expectations Theory
• Explains why the term structure of interest rates changes at different times
• Explains why interest rates on bonds with different maturities move together over time (fact 1)
• Explains why yield curves tend to slope up when short-term rates are low and slope down when short-term rates are high (fact 2)
• Cannot explain why yield curves usually slope upward (fact 3)
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-66
Segmented Markets Theory
• Bonds of different maturities are not substitutes at all
• The interest rate for each bond with a different maturity is determined by the demand for and supply of that bond
• Investors have preferences for bonds of one maturity over another
• If investors generally prefer bonds with shorter maturities that have less interest-rate risk, then this explains why yield curves usually slope upward (fact 3)
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-67
Liquidity Premium & Preferred Habitat Theories• The interest rate on a long-term bond will
equal an average of short-term interest rates expected to occur over the life of the long-term bond plus a liquidity premium that responds to supply and demand conditions for that bond
• Bonds of different maturities are partial (not perfect) substitutes

Preferred Habitat Theory
• Investors have a preference for bonds of one maturity over another
• They will be willing to buy bonds of different maturities only if they earn a somewhat higher expected return
• Investors are likely to prefer short-term bonds over longer-term bonds
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-70
FIGURE 5 The Relationship Between the Liquidity Premium (Preferred Habitat) and Expectations Theory
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-71
Liquidity Premium and Preferred Habitat Theories• Interest rates on different maturity bonds move
together over time; explained by the first term in the equation
• Yield curves tend to slope upward when short-term rates are low and to be inverted when short-term rates are high; explained by the liquidity premium term in the first case and by a low expected average in the second case
• Yield curves typically slope upward; explained by a larger liquidity premium as the term to maturity lengthens

How the Market Sets Prices
• The price is set by the buyer willing to pay the highest price
• The market price will be set by the buyer who can take best advantage of the asset
• Superior information about an asset can increase its value by reducing its perceived risk
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-80
How the Market Sets Prices
• Information is important for individuals to value each asset.
• When new information is released about a firm, expectations and prices change.
• Market participants constantly receive information and revise their expectations, so stock prices change frequently.
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-81
Adaptive Expectations
• Expectations are formed from past experience only.
• Changes in expectations will occur slowly over time as data changes.
• However, people use more than just past data to form their expectations and sometimes change their expectations quickly.
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-82
Theory of Rational Expectations• Expectations will be identical to optimal forecasts
using all available information• Even though a rational expectation equals the
optimal forecast using all available information, a prediction based on it may not always be perfectly accurate– It takes too much effort to make the expectation the best
guess possible– Best guess will not be accurate because predictor is
unaware of some relevant information
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-83
Implications
• If there is a change in the way a variable moves, the way in which expectations of the variable are formed will change as well– Changes in the conduct of monetary policy (e.g.
target the federal funds rate)• The forecast errors of expectations will, on
average, be zero and cannot be predicted ahead of time.
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-84
Efficient Markets
• Current prices in a financial market will be set so that the optimal forecast of a security’s return using all available information equals the security’s equilibrium return
• In an efficient market, a security’s price fully reflects all available information
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-85
Evidence on Efficient Markets Hypothesis
Favorable Evidence1. Stock prices reflect publicly available information: anticipated
announcements don’t affect stock price2. Stock prices and exchange rates close to random walk
If predictions of P big, Rof > R* predictions of P smallUnfavorable Evidence1. Small-firm effect: small firms have abnormally high returns2. January effect: high returns in January3. Market overreaction4. New information is not always immediately incorporated into
stock pricesOverviewReasonable starting point but not whole story
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-86
Application Investing in the Stock Market• Recommendations from investment advisors
cannot help us outperform the market• A hot tip is probably information already
contained in the price of the stock• Stock prices respond to announcements
only when the information is new and unexpected
• A “buy and hold” strategy is the most sensible strategy for the small investor
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-87
Behavioral Finance
• The lack of short selling (causing over-priced stocks) may be explained by loss aversion
• The large trading volume may be explained by investor overconfidence
• Stock market bubbles may be explained by overconfidence and social contagion

Adverse Selection and Moral Hazard: DefinitionsAdverse Selection:1.Before transaction occurs2.Potential borrowers most likely to produce
adverse outcomes are ones most likely to seek loans and be selected
Moral Hazard:1.After transaction occurs2.Hazard that borrower has incentives to engage in
undesirable (immoral) activities making it more likely that won’t pay loan back

Adverse Selection and Financial StructureLemons Problem in Securities Markets1. If investors can’t distinguish between good and bad
securities, they are only willing to pay only average of good and bad securities’ values.
2. Result: Good securities undervalued and firms won’t issue them; bad securities overvalued, so too many issued.
3. Investors won’t want to buy bad securities, so market won’t function well.Explains Less asymmetric information for well known firms, so smaller lemons problem

Asset and Liability ManagementAsset Management1. Get borrowers with low default risk, paying high
interest rates2. Buy securities with high return, low risk3. Diversify4. Manage liquidityLiability Management1. Important since 1960s2. Banks no longer primarily depend on deposits3. When see loan opportunities, borrow or issue CDs to
acquire funds
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-109
Capital Adequacy Management1. Bank capital is a cushion that helps prevent bank failure2. Higher is bank capital, lower is return on equity
ROA = Net Profits/AssetsROE = Net Profits/Equity CapitalEM = Assets/Equity CapitalROE = ROA EMCapital , EM , ROE
3. Tradeoff between safety (high capital) and ROE4. Banks also hold capital to meet capital requirements5. Managing Capital:
A. Sell or retire stockB. Change dividends to change retained earningsC. Change asset growth
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-110
Application: How a Capital Crunch Caused a Credit Crunch in 2008
• Shortfalls of bank capital led to slower credit growth– Huge losses for banks from their holdings of
securities backed by residential mortgages.– Losses reduced bank capital
• Banks could not raise much capital on a weak economy, and had to tighten their lending standards and reduce lending.

= $20 – $50 = –$30 millionWhen i 5%:1. Income on assets = + $1 million
(= 5% $20m)2. Costs of liabilities = +$2.5 million
(= 5% $50m)3. Profits = $1m – $2.5m = –$1.5m

Duration AnalysisDuration Analysis
% value –(% pointi) (DUR)Example: i 5%, duration of bank assets = 3 years, duration of liabilities = 2 years;
% assets = –5% 3 = –15%% liabilities = –5% 2 = –10%
If total assets = $100 million and total liabilities = $90 million, then assets $15 million, liabilities$9 million, and bank’s net worth by $6 millionStrategies to Manage Interest-rate Risk1. Rearrange balance-sheet2. Interest-rate swap3. Hedge with financial futures

3.Trading ActivitiesA. Financial futuresB. Financial optionsC. Foreign exchangeD. Swaps
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-116
Off-Balance-Sheet Activities
• Loan sales (secondary loan participation)• Generation of fee income. Examples:
– Servicing mortgage-backed securities.– Creating SIVs (structured investment vehicles)
which can potentially expose banks to risk, as it happened in the subprime financial crisis of 2007-2008.
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-117
Off-Balance-Sheet Activities
• Trading activities and risk management techniques – Financial futures, options for debt instruments,
interest rate swaps, transactions in the foreign exchange market and speculation.
– Principal-agent problem arises
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-118
Off-Balance-Sheet Activities
• Internal controls to reduce the principal-agent problem– Separation of trading activities and bookkeeping– Limits on exposure– Value-at-risk– Stress testing

for them to raise funds
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-124
Banks’ Response
Loss of cost advantages in raising funds and income advantages in making loans causes reduction in profitability in traditional banking1. Expand lending into riskier areas: e.g., real estate2. Expand into off-balance sheet activities3. Creates problems for U.S. regulatory systemSimilar problems for banking industry in other countries

Bank Consolidation and Number of Banks
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-130
Bank Consolidation and Nationwide Banking• The number of banks has declined over
the last 25 years– Bank failures and consolidation.– Deregulation: Riegle-Neal Interstate Banking
and Branching Efficiency Act f 1994.– Economies of scale and scope from
information technology.• Results may be not only a smaller
number of banks but a shift in assets to much larger banks.
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-131
Benefits and Costs of Bank Consolidation• Benefits
– Increased competition, driving inefficient banks out of business
– Increased efficiency also from economies of scale and scope
– Lower probability of bank failure from more diversified portfolios
• Costs– Elimination of community banks may lead to less
lending to small business– Banks expanding into new areas may take increased
risks and fail

How Asymmetric InformationExplains Banking Regulation
1.Government Safety Net and Deposit InsuranceA. Prevents bank runs due to asymmetric information:
depositors can’t tell good from bad banksB. Creates moral hazard incentives for banks to take
on too much riskC. Creates adverse selection problem of crooks and
risk-takers wanting to control banksD. Too-Big-to-Fail increases moral hazard incentives for
big banks2.Restrictions on Asset Holdings
A. Reduces moral hazard of too much risk taking
Copyright © 2010 Pearson Addison-Wesley. All rights reserved.1-134
3.Bank Capital RequirementsA. Reduces moral hazard: banks have more to lose when
have higher capitalB. Higher capital means more collateral for FDIC
4.Bank Supervision: Chartering and ExaminationA. Reduces adverse selection problem of risk takers or
crooks owning banksB. Reduces moral hazard by preventing risky activities
5.New Trend: Assessment of Risk Management6.Disclosure Requirements
A. Better information reduces asymmetric information problem
