Merge

I don't really edit economics articles, but has anyone considered merging this and complement good into substitute and complement goods? They are a closely intertwined topic, and one will usually study the two together. Richard001 09:20, 13 September 2007 (UTC)

Confusion

(1) The discussion of Different Types refers to the partial of X with respect to PsubY, but does not define what X stands for or what PsubY stands for. This may be obvious to those who already understand the subject but it is completely unclear to me. (2) I have no problems understanding math notation, but I suspect that whatever a perfect and a gross substitute are, they can easily be explained in language.

Continuation - perhaps the meaning of the statement that the partial of X with respect to PsubY > 0 is "Given a pair of goods, if an increase in the price of the first causes an increase in the demand for the second, then the second is considered to be a gross substitute of the first." An advantage in expressing the idea this way (if I have correctly guessed the meanings of the symbols) is that it is accessible to everyone, not merely those who took freshman calculus.

Substitute good graph

I added a graph to the entry but it is kidn of small and I cannot exactly figure out to resize it in the article. Sorry I am fairly new to editing wikipedia. — Preceding unsigned comment added by Mitch4445 (talk • contribs) 18:34, 31 March 2011 (UTC)
