摘要：

This paper argues that an important part of movements in asset prices may be caused by neither external news nor irrationality, but by the revelation of information by the trading process itself. Two models are developed that illustrate this general idea. One model is based on investor uncertainty about the quality of other investors' information; the other is based on widespread dispersion of information and small costs to trading. The analysis is used to suggest a possible rational explanation of the October 1987 crash.
