How Human Action and Human Values Determine Prices
Why do individuals pay much higher prices for some goods versus other goods? The common reply to this is the law of supply and demand. What is behind this law? To provide an answer to this question economists refer to the law of diminishing marginal utility.
Mainstream economics explains the law of diminishing marginal utility in terms of the satisfaction that one derives from consuming a particular good. For instance, an individual derives vast satisfaction from consuming one cone of ice cream.
