Talk:Complete market

Merge
I think that if anything 'complete market' should be merged into this one. There are textbooks out there entitled "Incomplete markets" and the subject matter is generally known as "Incomplete markets theory".radek 19:13, 3 October 2006 (UTC)


 * Support merge either way - no need for 2 articles. History2007 (talk) 11:47, 19 June 2010 (UTC)


 * Do not merge The study of incomplete markets arises from the failure of Complete Markets. It is not that one thing is embeded in the other. Complete Markets is in itself the basic framework for the theory of Arrow-Debreu Equilibrium, a milestone in modern economics. On the other hand, Incomplete markets provides a framework to study economic activity where the assumptions of Complete Markets no longer hold. It is set up to undestand, not only why market are incomplete, but its consequences in the economic and financial activity of individuals and institutions. I think, for ease of presentation and to make a clear distinction between the two, it would be better to leave separate artciles on 'Complete' and 'Incomplete' markets. — Preceding unsigned comment added by Apedraza1982 (talk • contribs) 20:38, 8 March 2011 (UTC)

Complete vs Perfect
The conditions given for a complete market are the ones of what is usually called a perfect market. Complete / Arrow-Debreu markets are those for which every contingent claim has a replicating portfolio.Nmdwolf (talk) 12:36, 1 March 2024 (UTC)

Self-financing
Definition of a self-financing trading strategy (intuitive): A portfolio is self-financing if there is no exogenous infusion or withdrawal of money. “The purchase of a new asset must be financed by the sale of an old one.” Cutnyakdhien 20:36, 2 February 2008

Trading strategy, contingent claim
Can we please define them? I linked them to WP articles, but to me it seems that the original editor had different concetps in mind. 58.88.53.246 (talk) 10:51, 26 October 2008 (UTC)

Merger proposal
I propose that "Arrow–Debreu model" be merged into "Complete market." The model is but an expression of the complete-market notion. It all comes down to the same exact ideas, expressed differently. Wikipedia users would benefit from having the model as a (large) section of the "complete markets" article. What do others think? (Note: Discussing the merger will be done, according to the rules, here, in the target article's talk page.) Take care, all. -The Gnome (talk) 09:55, 4 April 2018 (UTC)
