Continuous Time Equilibrium Pricing of Nonredundant Assets.

The problem of fair pricing of contingent claims is well understood in the context of an arbitrage free, complete financial market, with perfect information. But in the more realistic context of an incomplete market with imperfect information, the arbitrage approach does not enable us to aobtain a unique faire price for all contingent claims but only a fair pricing interval, which is known to be too large to be of creat interest. We present here a new approach by exploiting partial conditions issued from equilibrium analysis.
