The principle that to obtain the greatest total utility, a consumer should allocate money income so that the last dollar spent on each good or service yields the same marginal utility (MU). For two goods X and Y, with prices Px and Py, total utility will be maximized by purchasing the amounts of X and Y such that MUx/Px = MUy/Py for the last dollar spent on each good.

Budget Constraint

The limitations on the consumption choices of an individual or family due to limited financial resources.

Product Alpha

A term often used to define the first version or iteration of a product, typically before it is released to the general public for feedback.
