Fluctuating Confidence in Stock Markets: Implications for Returns and Volatility
TL;DR: In this paper, the authors present the special properties of a filter in continuous time that characterizes the dynamics of Bayesian learning about recurrent profitability switches and their relation to fluctuating confidence, which is reflected in the statistical properties of interest rate and stock return processes in a Cox-Ingersoll-Ross (1985a and b) style general equilibrium model.
Journal ArticleDOI
Heterogeneous Beliefs, Speculation, and the Equity Premium
TL;DR: In this paper, the authors show that agents with heterogeneous beliefs about fundamental growth do not perfectly share risks but instead speculate with each other on the relative accuracy of their models' predictions and face the risk that market prices move more in line with the trading models of competing agents rather than their own.
Journal ArticleDOI

TL;DR: In this article, a general equilibrium model was proposed to explain the stochastic changes in stock and Treasury bond comovement, volatilities and their relations to their price valuations and fundamentals change stochastically over time.
Journal ArticleDOI
