Supply and Demand Analysis ofthe Bond Market
Market Equilibrium
1. Occurs when Bd = B
s, at P* =
$850, i* = 17.6%
2. When P = $950, i = 5.3%, Bs >
Bd (excess supply): P to P*, i
to i*
3. When P = $750, i = 33.0, Bd >
Bs (excess demand): P to P*,
i to i*

Shifts in the Bond Demand Curve
![Page 5: Chapter 5 The Behavior of Interest Rates](https://reader036.fdocuments.in/reader036/viewer/2022062302/568167f0550346895ddd608e/html5/thumbnails/5.jpg)
Factors that Shift the Bond Demand Curve
1. WealthA. Economy grows, wealth , Bd , Bd shifts out to right
2. Expected ReturnA. i in future, Re for long-term bonds , Bd shifts out to rightB. e , Relative Re , Bd shifts out to rightC. Expected return relative to other assests , Bd , Bd shifts out to right
3. RiskA. Risk of bonds , Bd , Bd shifts out to rightB. Risk of other assets , Bd , Bd shifts out to right
4. LiquidityA. Liquidity of Bonds , Bd , Bd shifts out to rightB. Liquidity of other assets , Bd , Bd shifts out to right

Factors that Shift Demand Curve for Bonds

Shifts in the Bond Supply Curve
1. Profitability of Investment Opportunities
Business cycle expansion, investment opportunities , Bs , Bs shifts out to right
2. Expected Inflatione , Bs , Bs shifts out to right
3. Government Activities
Deficits , Bs , Bs shifts out to right

Changes in e: the Fisher Effect
If e 1. Relative RETe ,
Bd shifts in to left
2. Bs , Bs shifts out to right
3. P , i

Evidence on the Fisher Effect in the United States

Business Cycle Expansion
1. Wealth , Bd , Bd shifts out to right
2. Investment , Bs , Bs shifts out to right
3. If Bs shifts more than Bd then P , i

Evidence on Business Cycles and Interest Rates
![Page 13: Chapter 5 The Behavior of Interest Rates](https://reader036.fdocuments.in/reader036/viewer/2022062302/568167f0550346895ddd608e/html5/thumbnails/13.jpg)
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
![Page 14: Chapter 5 The Behavior of Interest Rates](https://reader036.fdocuments.in/reader036/viewer/2022062302/568167f0550346895ddd608e/html5/thumbnails/14.jpg)
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
![Page 15: Chapter 5 The Behavior of Interest Rates](https://reader036.fdocuments.in/reader036/viewer/2022062302/568167f0550346895ddd608e/html5/thumbnails/15.jpg)
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 slope
Derivation of Supply curve1. Assume that central bank controls Ms and it is a fixed amount2. Ms curve is vertical line
Market 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%

Rise in Income or the Price Level
1. Income , Md , Md shifts out to right
2. Ms unchanged3. i* rises from i1 to i2

Rise in Money Supply
1. Ms , Ms shifts out to right2. Md unchanged3. i* falls from i
1 to i

Money and Interest Rates
Effects of money on interest rates1. Liquidity Effect
Ms , Ms shifts right, i 2. Income Effect
Ms , Income , Md , Md shifts right, i 3. Price Level Effect
Ms , Price level , Md , Md shifts right, i 4. Expected Inflation Effect
Ms , e , Bd , Bs , Fisher effect, i Effect of higher rate of money growth on interest rates is ambiguous1. Because income, price level and expected inflation effects work in opposite direction of liquidity effect
