Abstract
This paper analyzes the sensitivity of market crashes to investors’
psychology in a standard general equilibrium framework. Contrary to
the traditional view that market crashes are driven by large drops in
aggregate endowments, we argue from a theoretical standpoint that
individual anticipations of such drops are a necessary condition for
crashes to occur, and that the magnitude of such crashes are positively
correlated with the level of individual anticipations of drops.
