Talk:Income elasticity of demand

message: I changed the formula for the elasticity itself to be equal to epsilon, since that notation seems used quite often. 153.90.172.153 19:41, 12 October 2007 (UTC)

message: :Image:Pyat rublei 1997.jpg is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.
Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.
If there is  other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page.  Note that any fair use images uploaded after 4 May, 2006, and lacking such an explanation will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you.

thread_title:  Diagram 

message: Anyone else feels this section needs a bit of expanding?, It needs some formulas that are easer to understand before getting simplified to what is showing now. (an equivalent of [] would be nice) --Majikthise 110 (talk) 19:56, 13 December 2007 (UTC)

thread_title: Include YED in the title

message: I notice that all of the equations in this article refer to income as "I."  The normal letter to refer to income is "Y," since "I" is already used for Investment.  This is significant because it is at odds with other economics articles on Wikipedia and even with it's own article title (YED).  It took me a few seconds to figure out that I refereed to income once I arrived at this article (I was looking for the equations specifically) and I was momentarily disoriented as I read upwards to figure out the notation from the diagram.  This is especially important since nowhere in the article are the terms used in the equation defined.
Unless anyone has any objections I shall change all the equations and the diagram to to use "Y" instead of "I" and add a note on what the terms in the equations mean right before that section. - Havell (talk) 02:34, 23 January 2009 (UTC)
