1 The Behavior of Interest Rates
Chapter 5 The Behavior of Interest Rates

2 Determining the Quantity Demanded of an Asset
Wealth(財富): the total resources owned by the individual, including all assets Expected Return(預期報酬): the return expected over the next period on one asset relative to alternative assets Risk(風險): the degree of uncertainty associated with the return on one asset relative to alternative assets Liquidity(流動性): the ease and speed with which an asset can be turned into cash relative to alternative assets

3 Theory of Asset Demand (資產需求理論)
Holding all other factors constant(當其他一切因素不變時): The quantity demanded of an asset is positively related to wealth(財富) The quantity demanded of an asset is positively related to its expected return(預期報酬) relative to alternative assets The quantity demanded of an asset is negatively related to the risk (風險) of its returns relative to alternative assets The quantity demanded of an asset is positively related to its liquidity(流動性) relative to alternative assets

4 Summary Table 1 Response of the Quantity of an Asset Demanded to Changes in Wealth, Expected Returns, Risk, and Liquidity

5 Supply and Demand for Bonds
At lower prices (higher interest rates), ceteris paribus(其他一切不變), the quantity demanded of bonds is higher: an inverse relationship At lower prices (higher interest rates), ceteris paribus, the quantity supplied of bonds is lower: a positive relationship

6 Figure 1 Supply and Demand for Bonds

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

8 Market Equilibrium Occurs when the amount that people are willing to buy (demand) equals the amount that people are willing to sell (supply) at a given price Bd = Bs defines the equilibrium (or market clearing) price and interest rate. When Bd > Bs , there is excess demand, price will rise and interest rate will fall When Bd < Bs , there is excess supply, price will fall and interest rate will rise

11 Shifts in the Demand for Bonds
Wealth: in an expansion with growing wealth, the demand curve for bonds shifts to the right Expected Returns: higher expected interest rates in the future lower the expected return for long-term bonds, shifting the demand curve to the left Expected Inflation: an increase in the expected rate of inflations lowers the expected return for bonds, causing the demand curve to shift to the left Risk: an increase in the riskiness of bonds causes the demand curve to shift to the left Liquidity: increased liquidity of bonds results in the demand curve shifting right

14 Shifts in the Supply of Bonds
Expected profitability of investment opportunities(投資機會的預期獲利): in an expansion, the supply curve shifts to the right Expected inflation(預期通貨膨脹): an increase in expected inflation shifts the supply curve for bonds to the right Government budget(政府預算): increased budget deficits shift the supply curve to the right

Mishkin, “The Real Interest Rate: An Empirical Investigation,” Carnegie-Rochester Conference Series on Public Policy 15 (1981): 151–200. These procedures involve estimating expected inflation as a function of past interest rates, inflation, and time trends.

25 Demand for Money in the Liquidity Preference Framework
As the interest rate increases: The opportunity cost of holding money(持有或幣的機會成本) increases… The relative expected return of money(貨幣的預期報酬) decreases… …and therefore the quantity demanded of money decreases.

26 Changes in Equilibrium Interest Rates in the Liquidity Preference Framework
Shifts in the demand for money: Income Effect(所得效果): a higher level of income causes the demand for money at each interest rate to increase and the demand curve to shift to the right Price-Level Effect(價格水準效果): a rise in the price level causes the demand for money at each interest rate to increase and the demand curve to shift to the right

27 Shifts in the Supply of Money
Assume that the supply of money is controlled by the central bank(中央銀行) An increase in the money supply engineered by the Federal Reserve will shift the supply curve for money to the right

30 Summary Table 4 Factors That Shift the Demand for and Supply of Money

31 Price-Level Effect (價格效果) and Expected-Inflation Effect(預期通膨效果
A one time increase in the money supply will cause prices to rise to a permanently higher level by the end of the year. The interest rate will rise via the increased prices. Price-level effect remains even after prices have stopped rising. A rising price level will raise interest rates because people will expect inflation to be higher over the course of the year. When the price level stops rising, expectations of inflation will return to zero. Expected-inflation effect persists only as long as the price level continues to rise.

32 Does a Higher Rate of Growth of the Money Supply(貨幣成長率較高) Lower Interest Rates(降低利率)?
Liquidity preference framework leads to the conclusion that an increase in the money supply will lower interest rates: the liquidity effect(流動性效果). Income effect(所得效果) finds interest rates rising because increasing the money supply is an expansionary influence on the economy (the demand curve shifts to the right).

33 Does a Higher Rate of Growth of the Money Supply Lower Interest Rates
Does a Higher Rate of Growth of the Money Supply Lower Interest Rates? (cont’d) Price-Level effect predicts an increase in the money supply leads to a rise in interest rates in response to the rise in the price level (the demand curve shifts to the right). Expected-Inflation effect shows an increase in interest rates because an increase in the money supply may lead people to expect a higher price level in the future (the demand curve shifts to the right).
