Talk:Incomplete markets

simultaneous

if there's not all people can trade at the market simultaneously because they have finite life-time, is it incomplete market? —Preceding unsigned comment added by 71.113.225.20 (talk • contribs)

Yes. In models with overlapping generations, markets are incomplete due to the inability of future generations to form contracts with currently living agents. This results in dynamic inefficiency as young agents tend to save too much relative to a counterfactual with complete contracts. Quant-macro (talk) 04:10, 19 February 2026 (UTC)

opaque

The article is a great example of "academe speak" -- completely opaque to intelligent non-experts. As one of them (intelligent non-experts), let me cut through the obfuscation. Free market and perfect competition are ideal constructs and cannot exist in the real world. The theory that comes nearest to providing a foundation for such constructs in the real world is Binary Economics. Admittedly it is inadequatly presented here at the moment, but should not be ignored. -- Janosabel 12:23, 26 May 2007 (UTC)

Yes it should be ignored. And is. —Preceding unsigned comment added by 128.143.1.87 (talk) 04:54, 14 August 2008 (UTC)

Precautionary saving and heterogeneous agents models

Market incompleteness is a key assumption that generates interesting behavior in models with heterogeneous agents. I suggest adding a section that describes this strand of literature. Quant-macro (talk) 04:12, 19 February 2026 (UTC)
