Abstract : This paper investigates effects of coarse information on the variability of asset prices by assuming that uninformed traders face ambiguity in the model of Grossman and Stiglitz (1980). We find that risk aversion plays a dominant role in generating excess volatility compared to coarse information. If the degree of risk aversion is sufficiently low, excess volatility does not arise, even when the degree of ambiguity is extremely high. On the contrary, if traders are sufficiently risk-averse, excess volatility occurs irrespective of ambiguity. When traders are moderately risk-averse, ambiguity makes excess volatility more likely. Keywords - Asymmetric information; coarse information; risk aversion
