[edit] Arrow theorem: restricted domain

Have you a reference for the following your assertion in the section "Some possibilities" of Arrow's impossibility theorem. IMHO such reference should be presented in the article.

::   Indeed, many different social choice functions can meet Arrow's conditions under such restricting of the domain. It has been proved, however, that any such restriction that makes any social choice function adhere with Arrow's criteria, will make the majority rule adhere with these criteria

There was a lot of work on graph theory and Agregation of preferences. Gil Klai from the Hebrew University did some research on that, I think. But I haven't read these things in the last couple of years, so I'll have to search. mousomer 20:14, 21 February 2006 (UTC)
