An empirical note on bond-yield uncertainty and the demand for money

This paper empirically tests the effect of bond-yield uncertainty on the demand for money, as implied by the capital theory approach to the demand for money, suggested by Friedman and Tobin. It is expected that the demand for money is affected not only by the yield on bonds (which are a substitute asset), but it also in increasing function of their risk. The empirical tests, which employ two alternative measures of uncertainty (mean of squared deviations from the average, and the mean of squared deviation from a predictor obtained by exponential smoothing) seem to support the Friedman-Tobin hypothesis.
