The Weak Axiom of Revealed Preference (WARP) needs to be included. 70.111.248.60 02:41, 19 April 2006 (UTC)
revealed preferred only means, "at least as good as." Not better than. So you have to have the concept of the consumer choosing A and not being indifferent between A and B to say that A is preferred to B. However, revealed preferred to is often stated so we don't know of B is just as good as or not. I don't see a great way to include this without overhauling the page. Before I do that, do others agree? Pdbailey ( talk) 23:55, 13 March 2008 (UTC)
You're right. I've reread the Mas-Colell, and the axiom is stated this way : if x and y belong to B and x belongs to C(B) (the choice correspondence), then for any B' with x and y belonging to B' and y belonging to C(B'), we must also have x belongs to C(B') —Preceding unsigned comment added by 91.163.195.76 ( talk) 21:25, 21 May 2008 (UTC)
Sinebot correctly gives definition 1.C.1 from Mas-Colell, Whinston and Green (MWG). But footnote 5 (p11) and exercise 1.C.1 from MWG make clear that we can't have y in C(B). (This is my 1st wikipedia submission so I hope it is ok.) Paulwhy ( talk) 16:14, 29 March 2009 (UTC)
This edit removed a criticism section. The section has problems (who is Koch?), for sure, but it also has at least some basis. Wong's book, for instance, is notable enough that Samuelson refers to it in an essay "How Foundations Came To Be". At least these references exist:
I'll pull out the truly dead links, and the section might want improvement, but it doesn't look like it merits complete removal. CRETOG8( t/ c) 23:11, 4 May 2011 (UTC)
I propose demonstrated preference be merged into revealed preference. The stated difference (that "demonstrated" preferences are not assumed constant) are not assumed in this article. If this article were repurposed for that, it might be appropriate, but there's no reason to do that. — Arthur Rubin (talk) 00:30, 19 December 2012 (UTC)

this article is pitched at WAY to high a level for a general encyclopedia what is wrong with you people ??? you want to do all that math, and use wierd terms like "budget set" fine, but first you have to write something the avg high school grad can understand total fail on that part — Preceding unsigned comment added by 24.91.49.238 ( talk) 04:33, 25 February 2014 (UTC)
If a child has a cookie and an apple and eats the apple first, you can't assume that they preferred the apple. Maybe they saved the cookie to get the horrid taste of apple out of their mouth. Or perhaps the intend to save the cookie for later. Or perhaps they are sick of cookies now but might like a cookie later. Order tells you nothing. Asking tells you everything. — Preceding unsigned comment added by Ggb667 ( talk • contribs) 15:46, 10 July 2014 (UTC)
Dr. Quah has reviewed this Wikipedia page, and provided us with the following comments to improve its quality:
The article is very misleading. Does not give an up-to-date account of revealed preference analysis at all -- for example, there is no discussion of Afriat's Theorem or Richter's Theorem or other canonical results in revealed preference. It is also narrow -- the idea of deducing preferences from observed actions is pervasive in economics and its application is not confined to consumer theory.
We hope Wikipedians on this talk page can take advantage of these comments and improve the quality of the article accordingly.
We believe Dr. Quah has expertise on the topic of this article, since he has published relevant scholarly research:

I understand that this article is about an old economic theory but its much too narrow and its very dry. Either another article is needed on the popular use of "Revealed Preference" or this article needs expansion.
Revealed preferences is a general term used to describe the way that people actually behave compared with the way they typically describe or present their behaviour (Expressed preference). Due to social, religious,cultural standards, general concerns about privacy or desire to manipulate others people often feel uncomfortable about expressing their true behaviour. Sometimes they themselves are unaware of their true behaviour. Sometimes they just lie. There is a human tendency to promote how we want to be perceived. This means interviews, and consumption and behaviour surveys have limited use in determining actual behaviour. This can have a huge impact on government spending, healthcare, insurance, advertising, new product launch. Examples are pornography where few people admit to consumption yet a multi billion dollar global business exists, and health care where people significantly over estimate the exercise they take and underestimate their consumption of food and alcohol.
I'd argue that the "free" social media companies like Google, Facebook have built their entire revenue business on the offer of exposing revealed preferences whether they are successful at it or not. The general use of loyalty cards, location tracking, tracking cookies, Bluetooth beacons are designed to build behaviour profiles to allow targeted and specific advertising based. — Preceding unsigned comment added by Stfual ( talk • contribs) 02:39, 26 June 2018 (UTC)
