Option 1: you get a check today for $10,000 and one ayear from now for $10,000.

Option 2: pays you $2,000 today and each of the next 29

years.

What are the present values of these two options, assuming a12% interest rate. Which option do you prefer? Why?

What if the interest rate was 10%?

What if you thought you might die, what does that mean forthe interest rate youd use?

When the coupon bond is priced at its face value, the yield to maturity

equals the coupon rate

The price of a coupon bond and the yield to maturity are negativelyrelated

The yield to maturity is greater than the coupon rate when the bond

price is below its face value


13/186

Discount BondYield to Maturity

For any one year discount bond

i=

F - P

P

F = Face value of the discount bond

P = current price of the discount bond

The yield to maturity equals the increase

in price over the year divided by the initial price.

As with a coupon bond, the yield to maturity is

negatively related to the current bond price.

F = face value of the Treasury bill (discount bond)

Always understates the yield to maturity

The understatement becomes more severe the longer the maturity

Rate of Return

and Interest Rates (contd)

The more distant a bonds maturity, the lower the rate of

return the occurs as a result of an increase in the interest rate

Even if a bond has a substantial initial

interest rate, its return can be negative if interest rates rise

Rate of Return and Interest Rates


19/186

Interest-Rate Risk

Prices and returns for long-term

bonds are more volatile than those for

shorter-term bonds

There is no interest-rate risk for any bond

whose time to maturity matches the holding

period


20/186

Real and Nominal Interest Rates

Nominal interest rate makes no allowancefor inflation

Real interest rate is adjusted for changes in price level so itmore accurately reflects the cost of borrowing

Ex ante real interest rate is adjusted for expected changes inthe price level

Ex post real interest rate is adjusted for actual changes in theprice level


21/186

The Liquidity Preference Framework

Keynesian model that determines the equilibrium interest rate

in terms of the supply of and demand for money.

There are two main categories of assets that people use to storetheir wealth: money and bo

s d

nds.

Total wealth in the economy = B M = B + M

Rearranging: B - B = M - M

If the market for money is in equilibrium (M = M ),

then the bond market is also in equilibrium (B = B ).


50/186

Liquidity Preference Analysis

Derivation of Demand Curve1. Keynes assumed money has i= 02. As i, relative RETeon money (equivalently, opportunity cost of money

) Md3. Demand curve for money has usual downward slope

Derivation of Supply curve1. Assume that central bank controls Msand it is a fixed amount2. Mscurve is vertical line

Market Equilibrium1. Occurs when Md= Ms, at i* = 15%2. If i = 25%, Ms> Md(excess supply): Price of bonds , ito i* = 15%3. If i=5%, Md> Ms(excess demand): Price of bonds , i to

i* = 15%

Shifts in the Demand for Money

Income Effecta higher level of income

causes the demand for money at each interest

rate to increase and the demand curve to shift

to the right

Price-Level Effecta rise in the price level

causes the demand for money at each interest

rate to increase and the demand curve to shiftto the right


53/186

Shifts in the Supply of Money

Assume that the supply of money is controlled

by the central bank

An increase in the money supply engineeredby the Federal Reserve

will shift the supply curve for money to the

right

Everything Else Remaining Equal?

Liquidity preference framework leads to the conclusion that anincrease in the money supply will lower interest ratesthe liquidityeffect.

Income effect finds interest rates rising because increasing the moneysupply is an expansionary influence on the economy.

Price-Level effect predicts an increase in the money supply leads to arise in interest rates in response to the rise in the price level.

Expected-Inflation effect shows an increase in interest rates because anincrease in the money supply may lead people to expect a higher pricelevel in the future.

Effect of higher rate of money growth on interest rates is ambiguous1. Because income, price level and expected inflation effects work inopposite direction of liquidity effect

Price Level Effect


59/186

Price-Level Effect

and Expected-Inflation Effect

A one time increase in the money supply will cause prices to rise to apermanently higher level by theend of the year. The interest rate will rise via the increased prices.

Price-level effect remains even after prices have stopped rising.

A rising price level will raise interest rates because people will expectinflation to be higher over the course of the year. When the price levelstops rising, expectations of inflation will return to zero.

Expected-inflation effect persists only as long as the price levelcontinues to rise.

Relation of Liquidity Preference

Framework to Loanable Funds

Keyness Major Assumption

Two Categories of Assets in Wealth

Money

Bonds

1. Thus: Ms+ Bs= Wealth

2. Budget Constraint: Bd+ Md= Wealth

3. Therefore: Ms+ Bs= Bd+ Md

4. Subtracting Mdand Bsfrom both sides:

MsMd= BdBs

Money Market Equilibrium5. Occurs when Md= Ms

6. Then MdMs= 0 which implies that BdBs= 0, so that Bd= Bsand bond market is

also in equilibrium



63/186

1. Equating supply and demand for bonds as in loanablefunds framework is equivalent to equating supply and

demand for money as in liquidity preference framework

2. Two frameworks are closely linked, but differ in practicebecause liquidity preference assumes only two assets,money and bonds, and ignores effects on interest rates

from changes in expected returns on real assets

3. Liquidity premium theory combines the two

theories to explain all three facts


79/186

Expectations Theory

The interest rate on a long-term bond will equal an averageof 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 holdany quantity of a bond if its expected returnis less than that of another bond with a different maturity

Bonds like these are said to be perfect substitutes


80/186

Expectations TheoryExample

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 bondsaverages (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 atdifferent times

Explains why interest rates on bonds with differentmaturities move together over time (fact 1)

Explains why yield curves tend to slope up when short-termrates are low and slope down when short-term rates arehigh (fact 2)

Cannot explain why yield curves usually slope upward (fact3)

S t d M k t Th


87/186

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 have short desired holding periods and generally prefer bonds

with shorter maturities that have less interest-rate risk, then this explains

why yield curves usually slope upward (fact 3)

Explanation of the Facts

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; explainedby a larger liquidity premium as the term to

and Term Structure Facts

Explains why yield curve has different slopes:

1. When short rates expected to rise in future, average of future short rates = int

is above todays short rate: therefore yield curve is upward sloping

2. When short rates expected to stay same in future, average of future shortrates are same as todays, and yield curve is flat

3. Only when short rates expected to fall will yield curve be downward sloping

Expectations Hypothesis explains Fact 1 that short and long rates move together

1. Short rate rises are persistent

2. If ittoday, ie

t+1, ie

t+2etc. average of future rates int

3. Therefore: itint, i.e., short and long rates move together


104/186

1. When short rates are low, they are expected to rise to normal level, and

long rate = average of future short rates will be well above todays short

rate: yield curve will have steep upward slope

2. When short rates are high, they will be expected to fall in future, and long

rate will be below current short rate: yield curve will have downward

slope

Doesnt explain Fact 3 that yield curve usually has upward slope

Short rates as likely to fall in future as rise, so average of future short

rates will not usually be higher than current short rate: therefore, yield

curve will not usually slope upward

Explains Fact 2 that yield curves tend to have steep slope when

short rates are low and downward slope when short rates are high



105/186


Key Assumption: Bonds of different maturities are not substitutes at allImplication: Markets are completely segmented: interest rate at each

maturity determined separately

Explains Fact 3 that yield curve is usually upward sloping

People typically prefer short holding periods and thus have higher demand for

short-term bonds, which have higher price and lower interest rates than longbonds

Does not explain Fact 1 or Fact 2 because assumes long and short rates

determined independently

If so, what item was it, why were people willing to accept it, and howwas the pattern of trades affected by the existence of a medium ofexchange? What were the advantages having a generally accepted

medium of exchange in this economy?

If not, why was there no generally accepted medium of exchange?

What would the effect on trading strategies have been if the storage

costs of all the goods had been equal?

R.A. Radford Economica, 1945, 189 201

According to Radford, did cigarettes function well as money in the POW camp? Was it important to their use as currency that cigarettes had intrinsic value?

Why would individuals re-roll their machine-rolled cigarettes?

What is the significance of the fact that a halving of Red Cross parcels changedprices?

What accounts for the fall in the value of the "bully mark"?

What happened to prices during an air raid? Why?

R.A. Radford Economica, 1945, 189-201

Important monetary ideas: Increase in cigarettes caused prices to rise (that is to say, the number of

cigarettes it took to buy a particular item increased).

Decrease in the number of cigarettes caused prices to fall.

Demand for cigarettes other than as money affected their ability to function asmoney (non-monetary demand). It also affected the relationship between

prices and the quantity of cigarettes Prices responded to expectationsof changes in the number of cigarettes.

Prisoners were forward looking, rational, and prices reflected those beliefsabout the future.

The Money Quote

"Lenin was certainly right. By a continuing process of inflation,governments can confiscate, secretly and unobserved, an importantpart of the wealth of their citizens. There is no subtler, no surermeans of overturning the existing basis of society than to debauch

the currency. The process engages all the hidden forces of economiclaw on the side of destruction, and does it in a manner which not oneman in a million is able to diagnose.." - John Maynard Keynes, `TheEconomic Consequences of The Peace'

Fiat money is the cause of inflation, and the amount which people

lose in purchasing poweris exactly the amount which was taken fromthem and transferred to their governments by this process. G.Edward Griffin, The Creature from Jekyll Island

A fiat monetary system allows power and influence to fall into the handsof those who control the creation of new money, and to those who get touse the money or credit early in its circulation. The insidious and eventualcost falls on unidentified victims who are usually oblivious to the cause oftheir plight. This system of legalized plunder (though not constitutional)allows one group to benefit at the expense of another. An actual transferof wealth goes from the poor and the middle class tothose in privileged

financial positions. Congressman Ron Paul (R-TX), "Paper Money andTyranny"

"It is well enough thatpeople of the nation do not understand our bankingand monetary system, for if they did, I believe there would be a revolutionbefore tomorrow morning." Henry Ford

2. Bank holds excess reserves

The Monetary Base


143/186

1. MB = C+ R= (Fed notes) + (bank deposits) + (Treasury currency)(coin)Asset = Liabilities of Fed balance sheet

2. (Fed notes) + (bank deposits) = (securities) + (discount loans) +

(gold and SDRs) + (coin) + (cash items in process of collection) + (other Fed

assets)(Treasury deposits)(foreign and other deposits)(deferred-

availability cash items)(other Fed liabs)

Float = (cash items in process of collection)(deferred-availability cash items)

Substituting 2 into 1 and using definition of float:

MB= (securities) + (discount loans) + (gold and SDRs) + (float) + (other Fed

assets) + (Treasury currency)(Treasury deposits)(foreign and other

deposits)(other Fed liabs)

Bryan gave a very passionate speech and "brought the delegates to their feet howling inecstasy with his cry toward the end: (Boller, p. 168)

We have petitioned, and our petitions have been scorned; we have entreated, and ourentreaties have been disregarded; we have begged, and they have mocked when ourclamity came. We beg no longer; we entreat no more. We defy them ...! Having behindus the producing masses of this nation and the world, supported by the commercialinterests, the laboring interests, and the toilers everywhere, we will answer theirdemand for a gold standard by saying to them: You shall not press down upon the browof labor this crown of thorns, you shall not crucify mankind upon a cross of gold!

1. Congress can amend Fed legislation

2. President appoints Chairmen and Board members and can influence legislation

Overall: Fed is quite independent

Other Central Banks

Criteria for Intermediate Targets

1. Measurability

2. Controllability

3. Ability to predictably affect goals

Interest rates arent clearly better than Mson criteria 1 and 2 because

hard to measure and control real interest rates

Criteria for Operating Targets

Same criteria as above

Reserve aggregates and interest rates about equal on criteria 1 and 2.

For 3, if intermediate target is Ms, then reserve aggregate is better
