11、ucation Canada Inc.,15,Evidence on Business Cycles and Interest Rates,16, 2005 Pearson Education Canada Inc.,Relation of Liquidity PreferenceFramework to Loanable Funds,Keyness Major Assumption Two Categories of Assets in Wealth Money Bonds 1.Thus:Ms + Bs = Wealth 2.Budget Constraint:Bd + Md = Wealt
12、h 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,17, 2005 Pearson Education Canada Inc.,1.Equating supply and dem
13、and 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 r
