Because the marginal rate of substitution of leisure for income is also the ratio of the marginal utility of leisure (MU L) to the marginal utility of income (MU Y), one can conclude: =, where Y is total income and the right side is the wage rate.
With ordinal utility, a person's preferences do not have a unique marginal utility, making the concept of diminishing marginal utility irrelevant. On the other hand, diminishing marginal utility is a significant concept in cardinal utility , which is used to analyse intertemporal choice , choice under uncertainty , and social welfare in modern ...
The marginal revenue product of a worker is equal to the product of the marginal product of labour (the increment to output from an increment to labor used) and the marginal revenue (the increment to sales revenue from an increment to output): =. The theory states that workers will be hired up to the point when the marginal revenue product is ...
Equal proportional sacrifice: The proportional loss of utility as a result of taxation should be equal for all taxpayers; Equal marginal sacrifice: The instantaneous loss of utility (as measured by the derivative of the utility function) as a result of taxation should be equal for all taxpayers. This therefore will entail the least aggregate ...
"Value in use" is the usefulness or utility of a commodity. A classical paradox often comes up when considering this type of value. In a passage of Adam Smith's An Inquiry into the Nature and Causes of the Wealth of Nations , he discusses the concepts of value in use and value in exchange, and notices how they tend to differ:
Since the subjective value holds that buyers use their own value judgements, the same goes for sellers, and thus the mechanism of production. Austrian economist Ludwig von Mises believes that production costs are determined by a seller's evaluations of their opportunity costs, or the sellers "marginal utility lost of having fewer of that good ...
Marginalism is a theory of economics that attempts to explain the discrepancy in the value of goods and services by reference to their secondary, or marginal, utility. It states that the reason why the price of diamonds is higher than that of water, for example, owes to the greater additional satisfaction of the diamonds over the water.
Economists distinguish between total utility and marginal utility. Total utility is the utility of an alternative, an entire consumption bundle or situation in life. The rate of change of utility from changing the quantity of one good consumed is termed the marginal utility of that good. Marginal utility therefore measures the slope of the ...
