Roughly speaking, in decision theory, game theory, and rational choice, menu dependence arises when the evaluation of alternatives for choice or the mode of selection guiding choice varies parametrically with what collection of alternatives is available for choice (i.e., with what "menu" or decision problem a decision maker is facing). Menu dependence can be accompanied by violations of various so-called consistency (or coherence) constraints, such as Sen's condition α (also known as Chernoff's Axiom, a contraction condition) and Sen's conditions γ and β (expansion conditions). While the phenomenon can arise in a variety of ways, menu dependence is often informally associated with a change in a decision maker's preferences among alternatives with the addition of irrelevant alternatives.

Famous quotes containing the words menu and/or dependence:
“The menu was stewed liver and rice, fricassee of bones, and shredded dog biscuit. The dinner was greatly appreciated; the guests ate until they could eat no more, and Elisha Dyer’s dachshund so overtaxed its capacities that it fell unconscious by its plate and had to be carried home.”
—For the State of Rhode Island, U.S. public relief program (1935-1943)
“As, therefore, we can have no dependence upon morality without religion;Mso, on the other hand, there is nothing better to be expected from religion without morality;Mnevertheless, ‘tis no prodigy to see a man whose real moral character stands very low, who yet entertains the highest notion of himself, in the light of a religious man.”
—Laurence Sterne (1713–1768)
