Analysis ofthe Bond MarketMarket Equilibrium1.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*6 2005 Pearson Education Canada Inc.Loanable Funds Terminology1.Demand for bonds=supply of loanable funds2.Supply of bonds=demand for loanable funds7 2005 Pearson Education Canada Inc.Shifts in the Bond Demand Curve8 2005 Pearson Education Canada Inc.Factors that Shift the Bond Demand Curve1.WealthA.Economy grows,wealth,Bd,Bd shifts out to right2.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 of other assests,Bd,Bd shifts out to right3.RiskA.Risk of bonds,Bd,Bd shifts out to rightB.Risk of other assets,Bd,Bd shifts out to right4.LiquidityA.Liquidity of Bonds,Bd,Bd shifts out to rightB.Liquidity of other assets,Bd,Bd shifts out to right9 2005 Pearson Education Canada Inc.Factors that Shift Demand Curve for

Inc.15Evidence on Business Cycles and Interest Rates16 2005 Pearson Education Canada Inc.Relation of Liquidity PreferenceFramework to Loanable FundsKeyness Major AssumptionTwo Categories of Assets in WealthMoneyBonds1.Thus:Ms+Bs=Wealth2.Budget Constraint:Bd+Md=Wealth3.Therefore:Ms+Bs=Bd+Md4.Subtracting Md and Bs from both sides:Ms Md=Bd BsMoney Market Equilibrium5.Occurs when Md=Ms6.Then Md Ms=0 which implies that Bd Bs=0,so that Bd=Bs and bond market is also in equilibrium17 2005 Pearson Education Canada Inc.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 framework2.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 assets18 2005 Pearson Education Canada Inc.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%19 2005 Pearson Education Canada Inc.Money Market Equilibrium20 2005 Pearson Education Canada Inc.Rise in Income or the Price Level1.Income ,Md ,Md shifts out to right2.Ms unchanged3.i*rises from i1 to i221 2005 Pearson Education Canada Inc.Rise in Money Supply1.Ms ,Ms shifts out to right2.Md unchanged3.i*falls from i1 to i222 2005 Pearson Education Canada Inc.2005

EffectMs,Price level,Md,Md shifts right,i 4.Expected Inflation EffectMs,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 effect24 2005 Pearson Education Canada Inc.Does Higher Money Growth Lower Interest Rates?2005 Pearson Education Canada Inc.25Evidence
