Information aggregation in dynamic markets with strategic traders

This paper studies information aggregation in dynamic markets with a finite number of partially informed strategic traders. It shows that for a broad class of securities, information in such markets always gets aggregated. Trading takes place in a bounded time interval, and in every equilibrium, as time approaches the end of the interval, the market price of a "separable" security converges in probability to its expected value based on the traders' pooled information.
