The model introduces an information structure which is intended to capture the notion that information is difficult to interpret. Strategic interaction and the complexity of the information result in a protracted price response. Indeed, equilibrium price paths of the model may display reversals in which the two traders rationally revise their beliefs, first in one direction, and then in the opposite direction, even though no new information has entered the system. A piece of information which is initially thought to be bad news may be revealed, through trading, to be good news. ER -
