Determinants of Asset Demand
Slide 4–4
Benefits of Diversification
1. Diversification almost always beneficial to risk-averse investor
2. Less returns of securities move together, greater is risk reduction from diversification

Derivation of Demand Curve
• Point A
Slide 4–6
Derivation of Demand Curve
• 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

Slide 4–8
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
Slide 4–9
Market Equilibrium
1. Occurs when Bd = Bs, 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*
Slide 4–10
Loanable Funds Terminology
1. Demand for bonds = supply of loanable funds
2. Supply of bonds = demand for loanable funds
Figure 4-2: A Comparison of Terminology: Loanable Funds and Supply and Demand for Bonds
Slide 4–11
Shifts in the Demand Curve
Figure 4-3: Shifts in the Demand Curve for Bonds
Slide 4–12
How Factors Shift the Demand Curve
1. Wealth– Economy , wealth , Bd , Bd shifts out to right
2. Expected Return– i in future, Re for long-term bonds , Bd shifts out to right– πe , relative Re , Bd shifts out to right
3. Risk– Risk of bonds , Bd , Bd shifts out to right– Risk of other assets , Bd , Bd shifts out to right
4. Liquidity– Liquidity of bonds , Bd , Bd shifts out to right– Liquidity of other assets , Bd ,Bd shifts out to right
Factors That Shift Demand Curve
Slide 4–14
Shifts in the Supply Curve
1. Profitability of Investment Opportunities– Business cycle
expansion, investment opportunities , Bs , Bs shifts out to right
2. Expected Inflation– πe , Bs , Bs shifts out
to right
3. Government Activities– Deficits , Bs , Bs
shifts out to rightFigure 4-4: Shift in the Supply Curve for Bonds
Factors That Shift Supply Curve
Slide 4–16
Changes in πe: The Fisher Effect
• If πe 1. Relative Re ,
Bd shifts in to left
2. Bs , Bs shifts out to right
3. P , i

Slide 4–18
Business Cycle Expansion
1. Wealth , Bd , Bd shifts out to right
2. Investment , Bs , Bs shifts right
3. If Bs shifts more than Bd then P , i

Slide 4–20
Relation of Liquidity Preference Framework to Loanable Funds
• Keynes’s 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 Md and Bs from both sides: Ms Md = Bd Bs
Slide 4–21
Relation of Liquidity Preference Framework to Loanable Funds
• 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
Slide 4–22
Relation of Liquidity Preference Framework to Loanable Funds
1. Equating supply and demand for bonds in loanable funds framework is equivalent to equating supply and demand for money 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
Slide 4–23
Liquidity Preference Analysis
• Derivation of Demand Curve1. Keynes assumed money has i = 02. As i , relative Re 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 is a fixed
amount2. Ms curve is vertical line
Slide 4–24
Liquidity Preference Analysis
• 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%

Money Market Equilibrium

Slide 4–26
Rise in Income
1. Income , Md , Md shifts out to right
2. Ms unchanged
3. i* rises from i1 to i2
Figure 4-11: Response to a Change in Income
Slide 4–27
Rise in Price Level
1. Price level , Md , Md shifts to right
2. Ms unchanged
3. i* rises from i1 to i2

Rise in Money Supply
1. Ms , Ms shifts out to right
2. Md unchanged
3. i* falls from i1 to i2

Money and Interest Rates
• Effects of money on interest rates1. Liquidity Effect
Ms , Ms shifts right, i
2. Income EffectMs , Income , Md , Md shifts right, i
3. Price Level EffectMs , Price level , Md , Md shifts right, i
4. Expected Inflation EffectMs , πe , Bd , Bs , Fisher effect, i
Slide 4–31
Money and Interest Rates
• Effect of higher rate of money growth on interest rates is ambiguous– Because income, price level and expected inflation effects
work in opposite direction of liquidity effect
Does Higher Money Growth Lower Interest Rates?

Slide 4–34
Profiting from Interest-Rate Forecasts
• Methods for forecasting1. Loanable funds: use Flow of Funds Accounts and judgment2. Econometric Models: large in scale, use liquidity preference
• Make decisions about assets to hold1. Forecast i , buy long bonds2. Forecast i , buy short bonds
• Make decisions about how to borrow1. Forecast i , borrow short2. Forecast i , borrow long

Supply and Demand in Gold Market
• Deriving Demand Curve
Re Pt1
e Pt
Pt
ge
1. Pet+1 is held constant
2. Pt , ge , Re Gd
3. Demand curve is downward sloping
• Deriving Supply Curve1. Pt , more production, Gs
2. Supply curve is upward sloping
Slide 4–36
Supply and Demand in Gold Market
• Market Equilibrium
1. Gd = Gs
2. If Pt > P* = P1, Gs > Gd, Pt to P*
3. If Pt < P* = P1, Gs < Gd, Pt to P*
Slide 4–37
Changes in Equilibrium
• Factors That Shift Demand Curve for Gold1. Wealth
2. Expected return on gold relative to alternative assets
3. Riskiness of gold relative to alternative assets
4. Liquidity of gold relative to alternative assets
• Factors That Shift Supply Curve for Gold1. Technology of mining
2. Government sales of gold
Slide 4–38
Response of Gold Market to a Change in πe
• If πe 1. πe , Pe
t+1 ; at given Pt, ge Gd Gd shifts right
2. Go to point 2; Pt
3. Price of gold positively related to πe
4. Gold price is barometer of π- pressure
