THE “FISHER EFFECT” FOR RISKY ASSETS: AN EMPIRICAL INVESTIGATION

THE EFFECT OF INFLATION on the returns to financial assets has been an important theoretical issue for many years. Due to our recent experience with unusually high rates of inflation, this effect is now of considerable practical importance. The basic theoretical concept in this area is commonly attributed to I. Fisher [1930] who posited that the nominal interest rate fully reflects the available information concerning the possible future values of the rate of inflation. This hypothesis, known as the "Fisher effect," has received wide acceptance among economists and has played an important role in monetary theory, finance, and macroeconomics. Others have extended Fisher's original insight to further explain the relationship between the interest rate and inflation. For example, Mundell (1963) uses the Pigou real balance effect to show that the real rate of interest is inversely related to inflation. Conversely, Santomero (1973) argues that changes in population may give rise to a direct relationship between the real rate of interest and inflation. The
