The Subjective Theory of Value

"The Principle of Marginal Utility

Valuation is always directed toward a definite quantity of a particular good or service. Choices and decisions are not concerned with the whole supply of a certain good or service. This marginal orientation was lacking in the classical economists' groping with the so-called paradox of value. They were unable to resolve the intriguing question of why diamonds had a higher price per unit than water when everyone knew that water was more useful and valuable than diamonds. Only through the principle of diminishing marginal utility could this conceptual dilemma be eliminated. Each additional unit of a particular good is devoted to a use that is less important and urgent than the use to which the preceding unit was applied...."

"...The principle of diminishing marginal utility and its complementary law of value resolve the paradox of value as exemplified by the discrepancy between the price of diamonds and the price of water. The element of scarcity in controlling the extent to which a particular commodity can be used holds the key. The relative abundance of water as compared with the availability of diamonds means that increments of water can be devoted to less and less important uses than those to which the limited amount of diamonds can be put. No one is ever in the predicament of having to choose between all water and all diamonds; thus there is no meaningful paradox. Prices arise in connection with definite amounts of goods and not in connection with whole categories of various goods...."
