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.

Keynes's schedule of the marginal efficiency of capital. Book IV discusses the inducement to invest, with the key ideas being presented in Chapter 11.

The marginal revenue curve is affected by the same factors as the demand curve – changes in income, changes in the prices of complements and substitutes, changes in populations, etc. [15] These factors can cause the MR curve to shift and rotate. [16]
Under the standard assumption of neoclassical economics that goods and services are continuously divisible, the marginal rates of substitution will be the same regardless of the direction of exchange, and will correspond to the slope of an indifference curve (more precisely, to the slope multiplied by −1) passing through the consumption bundle in question, at that point: mathematically, it ...
Your marginal tax rate is the rate of tax you pay on the portion of your income that falls in the highest tax bracket that applies to you. The IRS adjusts its tax brackets for inflation annually.
Average physical product (APP), marginal physical product (MPP) In economics and in particular neoclassical economics, the marginal product or marginal physical productivity of an input (factor of production) is the change in output resulting from employing one more unit of a particular input (for instance, the change in output when a firm's labor is increased from five to six units), assuming ...
