Preference (economics)
In economics and other social sciences, preference is the peculiar ordering of alternatives, based on their relative utility, a process which results in an optimal ""choice"" (whether real or theoretical). The character of the individual preferences is determined purely by taste factors, independent of considerations of prices, income, or availability of goods.With the help of the scientific method many practical decisions of life can be modelled, resulting in testable predictions about human behavior. Although economists are usually not interested in the underlying causes of the preferences in themselves, they are interested in the theory of choice because it serves as a background for empirical demand analysis.
