If a reduction in the price of one good reduces the demand for another, the two goods are called substitutes. According to the above Edge-worth-Pareto definition, complementary and substitution relations are reversible, that is, if good Y is complementary with X, X is complementary with Y; and if Y is substitute for X, X is substitute for Y Secondly, assuming that marginal utility of money remains constant, from the above definition it follows that if the price of good X talis and consequently the quantity demanded of good X increases, this will bring about an increase in the marginal utility of good Y if goods X and Y are complementary, and will therefore raise the demand for Y.

Therefore, when the income effect is strong enough to swamp the substitution effect for the commodity Y which has become relatively dearer due to the fall in price of good X, the purchases of both goods X and Y increase as a result of the fall in price of good X Then, on the basis of total price effect, the goods would be described as complements, even though they are in fact substitute goods.

Therefore, criticizing Paretos aforesaid parallelism Hicks remarks, the parallelism is not at all exact, as is made evident at once by the impossibility of discovering what degree of curvature of the indifference curves corresponds to the distinction between complementary and substitute goodswhich ought, on the above definition, to be a perfectly clear-cut distinction.
