Chapter 5 "History of interest rates and risk premiums" presents the following content: Factors influencing rates, level of interest rates, real vs. nominal rates, rates of return: single period, characteristics of probability distributions, mean scenario or subjective returns, variance or dispersion of returns,. | Chapter 5 History of Interest Rates and Risk Premiums Factors Influencing Rates Supply Households Demand Businesses Government’s Net Supply and/or Demand Federal Reserve Actions Q0 Q1 r0 r1 Funds Interest Rates Supply Demand Interest Rates Supply Q0 Q1 r0 r1 Funds Demand Level of Interest Rates Fisher effect: Approximation nominal rate = real rate + inflation premium R = r + i or r = R - i Example r = 3%, i = 6% R = 9% = 3% + 6% or 3% = 9% - 6% Fisher effect: Exact r = (R - i) / (1 + i) = (9%-6%) / () Empirical Relationship: Inflation and interest rates move closely together Real vs. Nominal Rates HPR = Holding Period Return P0 = Beginning price P1 = Ending price D1 = Dividend during period one Rates of Return: Single Period Ending Price = 48 Beginning Price = 40 Dividend = 2 HPR = (48 - 40 + 2 )/ (40) = 25% Rates of Return: Single Period Example 1) Mean: most likely value 2) Variance or standard deviation 3) Skewness * If a distribution is approximately normal, the distribution is described by characteristics 1 and 2.
