It shows that models of profitable informed trading must restrict the portfolio choices of uninformed traders: in particular, they cannot...

Noise traders are agents whose theoretical existence has been hypothesized as a way of solving certain fundamental problems in Financial Economics. We briefly review the literature on noise traders. The is an entry for The New Palgrave: A Dictionary of Economics, 2nd Edition (Palgrave Macmillan:...
