Abstract: We study equilibrium uniqueness in standard noisy rational expectations economies with asymmetric or differential information a la Grossman and Stiglitz (1980) and Hellwig (1980). The standard linear equilibrium of Grossman and Stiglitz (1980) is the unique equilibrium with a continuous price function. However, we also construct a tractable class of equilibria with discontinuous prices that have very different economic implications, including (i) jumps and crashes, (ii) “upward-sloping” demand curves, and (iii) price drift. Discontinuous equilibria can generate higher volatility, uncertainty, and illiquidity in recessions versus booms, and can feature higher welfare than the standard linear one. Discontinuous equilibria can be arbitrarily close to being fully-revealing and also exist under more general distributional assumptions and in the model of Hellwig (1980).
