This paper estimates an equilibrium model of stock price behaviour in which changes in exponentially de-trended dividends and prices are normally distributed and exogenous "noise traders" interact with "smart-money" investors who have constant absolute risk aversion. The model can explain the...

This article endogenizes information acquisition and portfolio delegation in a one-period strategic trading model. We find that, when the informed portfolio manager is relatively risk tolerant (averse), price informativeness increases (decreases) with the amount of noise trading. When noise...

A model of takeovers is investigated in which "noise trading" provides camouflage that makes it possible for a large corporate outsider to purchase enough shares at favorable prices so that takeovers become profitable. Although the model accommodates the possibility of dilution (Grossman and...

This paper derives and estimates an equilibrium model of stock price behavior in which exogenous "noise traders" interact with risk-averse "smart money" investors. The model assumes that changes in exponentially detrended dividends and prices are normally distributed, and that smart money...

Financial contagion is described as a wealth effect in a continuous-time model with two risky assets and three types of traders. Noise traders trade randomly in one market. Long-term investors provide liquidity using a linear rule based on fundamentals. Convergence traders with logarithmic...
