The paper provides a brief review of existing results on the transmission of information through prices, when the revealing equilibria have to fit a criterion of "eductive stability". The work under review often suggests that, at odds with the "efficient market hypothesis", the plausibility of...

This paper compares the most significant expectational stability criteria that have been used to assess the plausibility of perfect foresight trajectories in forward-looking dynamical systems: determinacy of trajectories, absence of neighbour sunspot trajectories, and convergence of "evolutive"...
