FYE

Is Francis Ysidro Edgeworth the eponym of this idea? If so, I'd like to add that fact to this article and to the one about Edgeworth. Michael Hardy 03:33, 10 May 2004 (UTC)Reply

Unfortunetly, the image accompanig this article is not one of an Edgeworth box - since it just shows one consumer. I'll try to find something better.radek 06:53, 14 January 2006 (UTC)Reply

  • Actually, this diagram does show two consumers, One from origin O, and the other from origin A. However, I will agree this diagram is not a good example, because the lines are too think and the colours all too similar, but also because it shows more than just the Edgeworth box - it introduces indifference curves, the PPF, and budget constraints, MRS, etc. These are not what this article should be concerned with - all of those things are tools, along with the Edgeworth box, used in general equilibrium analysis. I would suggest that the first diagram shown in this article, if there are multiple diagrams, should simply be the box showing how it is simply two graphs, with one rotated, that have been joined together, and how this then shows mixtures of consumption (or whatever is appropriate), given some point in the box. I may attempt this in the future. Narxysus 09:19, 3 February 2006 (UTC)Reply
I've added Image:Edgeworth-box-example.svg, hopefully this is OK. -- SilverStar 00:36, 29 November 2006 (UTC)Reply

Why Octavio and Abby

edit

Just out of curiosity, but WHY them? Who are they? My economics book uses Adam and Eve, apples and fig leaves. 117.18.231.29 (talk) 15:41, 13 June 2011 (UTC)Reply

The diagram's author probably follows a different creation story. Jonpatterns (talk) 16:38, 11 February 2018 (UTC)Reply
I reckon it derives from apples and oranges. Abba Lerner calls his consumers Mark and Victor because his commodities are meat and veg. (‘Economics of control’, p9). Colin.champion (talk) 07:20, 28 July 2020 (UTC)Reply

Tangency & budget line

edit

Fig. 3 shows that at equilibrium the common tangent has the same slope of the budget line. However, if we constrain the equilibrium to be on the budget line, then it will correspond to the intersection with the Pareto set with no assurance that common tangent to the indifference curves at equilibrium equals the slope of the budget line.
