This paper offers a continuous time, general equilibrium model where a risky asset is traded among risk-averse overconfident investors. Two kinds of overconfidence are introduced: investors exhibit relative overconfidence if each investor believes her model is better than others' and aggregate...

We show theoretically that when Bayesian investors face time-series uncertainty about assets' risk exposures, differences in their priors affect the pricing of risk in the cross-section: different priors for the same asset can generate differences in perceived risk exposures, and thereby...

Concepts from information theory are utilized to study the effects of entropy on the behavior of finance systems and variables of interest. From this analysis, a common entropic measure was derived that determines the structure and evolution of a wide variety of financial topologies. This...

Quarterly earnings conference calls convey fundamental information, as well as manager and analyst opinion about the firm. We examine how market uncertainty regarding firm valuation is affected by conference call tones. Using textual analysis of all publicly available earnings calls (2002-2012)...

We survey the textual sentiment literature, comparing and contrasting the various information sources, content analysis methods, and empirical models that have been used to date. We summarize the important and influential findings about how textual sentiment impacts on individual, firm-level and...

We show that aversion to risk and ambiguity leads to information inertia when investors process public news about assets. Optimal portfolios do not always depend on news that is worse than expected; hence, the equilibrium stock price does not reflect this bad news. This informational inefficiency...

A widely held belief in financial economics suggests that stock prices always adequately reflect all available information. Price movements away from fundamentals are assumed to occur only infrequently, if at all. „False“ prices are supposed to be corrected by the counter-actions of...
