Talk:Lexicographic preferences

Rewrite?
Could somebody who understands what this is about rewrite the example please? First it talks about X, Y, and Z, but then suddenly there are references to B. Also It says there are more items in bundle 2, but unless my basic arithmetic is wrong that is not the case. 72.227.136.130 02:12, 31 May 2006 (UTC)

convexity
In a book, I saw the author state that lexicographic preferences relation are strictly convex. However, I think that lexicographic preference relation is not necessarily to be convex, not to mention strictly convex. Although I admit that lexicographic order is strictly convex. 132.206.46.130 (talk) 00:36, 14 September 2008 (UTC)


 * Lexicographic preferences are indeed strictly convex. In $R^2$ the better-than set for any given point is a half plane with part of the boundary included and part not, which is a convex set.--Henriqueroscoe (talk) 05:34, 28 May 2010 (UTC)

Nonstandard reals
This is just a nonstandard utility function, with infinitesimal utilities. It shouldn't be made to look like a nontrivial paradox, it's the usual bullshit you can do with the real numbers. — Preceding unsigned comment added by 156.111.98.212 (talk) 21:09, 9 January 2013 (UTC)
