Revealed preferences theory

The revealed-preferences method involves determining the value that consumers hold for an environmental good by observing their purchase of goods in the market that directly or indirectly relate to environmental quality. For example, the purchase of air fresheners, noise-reducing materials, and water-purification systems… Much of the explanation for consumer behaviour, particularly consumer choice, is rooted in the concept of utility developed by the English philosopher and economist Jeremy Bentham. Utility represents want or desire satisfaction, which implies that it is subjective, individualized, and difficult to quantify.

Utility, or enjoyment from a good, is very hard to quantify so Samuelson set about looking for a way to do so. Since then it has expanded upon by a number of economists and remains a major theory of consumption behavior. The theory is especially useful in providing a method for analyzing consumer choice empirically.

The theory states that given a consumer's budget, they will select the same bundle of goods the "preferred" bundle as long as that bundle remains affordable. It is only if the preferential bundle becomes unaffordable that they will switch to a less expensive, less desirable bundle of goods.

Example of Revealed Preference For example, if consumer X purchases a pound of grapes, it is assumed under revealed preference theory that consumer X prefers that pound of grapes above all other items that cost the same, or are cheaper than, that pound of grapes.

Sorry! Something went wrong!

Since consumer X prefers that pound of grapes over all other items they can afford, they will only purchase something other than that pound of grapes if the pound of grapes becomes unaffordable.

If the pound of grapes becomes unaffordable, consumer X will then move on to a less preferable substitute item.What is Revealed Preference 'Revealed Preference' Revealed preference is an economic theory of consumption behavior which asserts that the best way to measure consumer preferences is to .
