ABSTRACT This paper reconsiders Harrod's knife‐edge instability of the capitalist economy. An investment function of the type used by Harrod is combined with a consumption function of the relative income hypothesis type. It will be shown that, even under such an investment function, knife‐edge instability can be ruled out if a part of consumption behaves steadily and capitalists do not change their expectations very rapidly.
