Optimal Choice  

In consumer theory, the optimal choice is the consumption bundle which maximizes the consumer's utility, given his available budget.

(Varian, Hal R. 2010. Intermediate Microeconomics: A Modern Approach, 8th ed. New York: W.W. Norton.)


At the heart of consumer theory in economics is the assumption that consumers are rational, utility-maximizing individuals who will make the choices that make them happiest, given their available resources. For example, in a two good model in which a consumer has a budget of $100, we assume he will choose, of all the affordable bundles, the combination of Good A and Good B which makes him happiest.

Another way of expressing this same point is that the consumer will buy the combination of goods which places him on the highest possible indifference curve. For this reason, when we are illustrating an optimal choice graphically, the optimal consumption position is where an indifference curve is tangent to the budget line.
