Psychological Aspects of Market Crashes


  • Patarick Leoni

    () (Economics Department, National University of Ireland, Maynooth)


This paper analyzes the sensitivity of market crashes to investors'psychology in a standard general equilibrium framwork. 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 or such crashes are poritively correlated with the level of individual anticipations of drops
