Mess

Wow. This article is REALLY bad. Being more specific than it needs to be fixed, I think it could be definitely shortened. Unless more could be said than just the definition, it should only be two paragraphs or so. However, a section could be added about the use of complementary good theory in firms... just a suggestion... - Bonzai273 —Preceding unsigned comment added by Bonzai273 (talkcontribs) 14:57, 21 March 2008 (UTC)

"Complementarity" -- correction of "complementariness"

In the 1st sentence of the 3rd paragraph, "complementarity" is the correct standard term, not "complementariness." Although the latter is grammatically correct, it's rarely used in economics in this specific context. --Jackftwist (talk) 16:49, 29 March 2010 (UTC)
