Derivation of Demand Curve(F – P)
i = RETe = ———P
Point A:
P = $950
($1000 – $950)i =—————— = .053 = 5.3%
$950
Bd = 100
![Page 3: Lecture 12 The Behavior of Interest Rates](https://reader036.vdocuments.us/reader036/viewer/2022062314/56813b01550346895da39f3d/html5/thumbnails/3.jpg)
5.5-3
Derivation of Demand CurvePoint B:
P = $900
($1000 – $900)i =—————— = .011 = 11.1%
$900
Bd = 200
Point C: P = $850 i = 17.6% Bd = 300
Point D: P = $800 i = 25.0% Bd = 400
Point E: P = $750 i = 33.0% Bd = 500
Demand Curve is Bd in Figure 1 which connects points A, B, C, D, E.
Has usual downward slope

Supply and Demand Analysis of the Bond Market
![Page 5: Lecture 12 The Behavior of Interest Rates](https://reader036.vdocuments.us/reader036/viewer/2022062314/56813b01550346895da39f3d/html5/thumbnails/5.jpg)
5.5-5
Derivation of Supply Curve
Point F: P = $750 i = 33.0% Bs = 100
Point G: P = $800 i = 25.0% Bs = 200
Point C: P = $850 i = 17.6% Bs = 300
Point H: P = $900 i = 11.1% Bs = 400
Point I: P = $950 i = 5.3% Bs = 500
Supply Curve is Bs that connects points F, G, C, H, I,
and has upward slope
Market Equilibrium
1. Occurs when Bd = B
s, at P* = 850, i* = 17.6%
2. When P = $950, i = 5.3%, Bs > B
d (excess supply): P to P*, i ≠ to i*
3. When P = $750, i = 33.0, Bd > B
s (excess demand): P ≠ to P*, i to i*

Loanable Funds Terminology
1. Demand for bonds = supply of loanable funds
2. Supply of bonds = demand for loanable funds

Response to a Low Savings Rate

Relation of Liquidity PreferenceFramework to Loanable Funds
Keynes Major Assumption
Two categories of assets in wealth
1. money
2. bonds
1. Thus: Ms + Bs = Wealth
2. Budget Constraint: Bd + Md = Wealth
3. Therefore: Ms + Bs = Bd + Md
4. Subtracting Md and Bs from both sides:
Ms – Md = Bd – Bs
Money Market Equilibrium
5. 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 18: Lecture 12 The Behavior of Interest Rates](https://reader036.vdocuments.us/reader036/viewer/2022062314/56813b01550346895da39f3d/html5/thumbnails/18.jpg)
5.5-18
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 from changes in expected returns on real assets

5.5-19
Liquidity Preference Analysis
Derivation of Demand Curve
1. Keynes assumed money has i = 0
2. As i ≠, RETe on money (equivalently, opportunity cost of money ≠)
fi Md
3. Demand curve for money has usual downward slope
Derivation of Supply curve
1. Assume that central bank controls Ms and is a fixed amount
2. Ms curve is vertical line
Market Equilibrium
1. Occurs when Md = M
s, at i* = 15%
2. If i = 25%, Ms > M
d (excess supply): Price of bonds ≠,
i to i* = 15%
3. If i =5%, Md > M
s (excess demand): Price of bonds ≠,
i to i* = 15%

Money and Interest Rates
Effects of money on interest rates
1. 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 ambiguous
1. Because income, price level and expected inflation effects work in opposite direction of liquidity effect
