The well known Sharpe-Lintner-Mossin capital asset pricing model (CAPM) assumes the existence of stability in the price level so that the market price of risk (MPR) measured in nominal terms is the same for all risky assets in an equilibrium market. Friend, Landskroner and Losq [5, hereafter F-L-L] have recently shown that CAPM measured in nominal terms understates the MPR if an uncertain inflation is expected and if a covariance between the rate of return on the market and the rate of inflation is positive (p. 1287).
