Revealed Preference
Revealed preference theory, pioneered by American economist Paul Samuelson, is a method for comparing the influence of policies on consumer behavior. These models assume that the preferences of consumers can be revealed by their purchasing habits. Revealed preference theory came about because existing theories of consumer demand were based on a diminishing marginal rate of substitution (MRS). This diminishing MRS relied on the assumption that consumers make consumption decisions to maximize their utility. While utility maximization was not a controversial assumption, the underlying utility functions could not be measured with great certainty. Revealed preference theory was a means to reconcile demand theory by defining utility functions by observing behavior.

Famous quotes containing the words revealed and/or preference:
“... we engage in politics because we don’t know anything. This is clearly revealed in the way we go about it. Our parties exist from a fear of theory. The voter fears that one idea can always be contradicted by another. Therefore the parties reciprocally defend themselves against the few old ideas they have inherited. They don’t live from what they promise, but from frustrating the promises of others. This is their silent community of interests.”
—Robert Musil (1880–1942)
“Moral choices do not depend on personal preference and private decision but on right reason and, I would add, divine order.”
—Basil Hume (b. 1923)
