We model limited attention as incomplete usage of publicly available information. Informed players decide whether or not to disclose to observers who sometimes neglect either disclosed signals or the implications of non-disclosure. In equilibrium observers are unrealistically optimistic,...

Peer review is fundamental to the efficacy of the scientific process. We draw from our experience both as editors, authors and association representatives to provide a set of guidelines for referees in preparing their reports and cover letters to journal editors. While our document is directed...

We derive a separation theorem: investors hold a common risk-adjusted market portfolio regardless of their information sets, and a portfolio based upon their private signals. This implies that investors have non-negligible holdings of assets they know little about, so nonparticipation remains a...

We propose that innovative originality (InnOrig) is a valuable organizational resource, and that owing to limited investor attention and skepticism of complexity, firms with greater InnOrig are undervalued. We find that firms' InnOrig strongly predicts higher, more persistent, and less volatile...

Individual investors often invest actively and lose thereby. Social interaction seems to exacerbate this tendency. In the model here, senders' propensity to discuss their strategies' returns, and receivers' propensity to be converted, are increasing in sender return. The rate of conversion of...

We find a positive association between short-selling and accruals during 1988-2009, and that asymmetry between the long and short sides of the accrual anomaly is stronger when constraints on short-arbitrage are more severe (low availability of loanable shares as proxied by institutional...

We examine the causal effect of limits to arbitrage on 11 well-known asset pricing anomalies using the pilot program of Regulation SHO, which relaxed short-sale constraints for a quasi-random set of pilot stocks, as a natural experiment. We find that the anomalies became weaker on portfolios...

This study tests whether naïve trading by individual investors, or some class of individual investors, causes post-earnings announcement drift (PEAD). Inconsistent with the individual trading hypothesis, individual investor trading fails to subsume any of the power of extreme earnings surprises...

We document strong persistence in the performance of trades of individual investors. The correlation of the risk-adjusted performance of an individual across sample periods is about 10 percent. Investors classified in the top performance decile in the first half of our sample subsequently...

This paper models firms' choices between alternative means of presenting information, and the effects of different presentations on market prices when investors have limited attention and processing power. In a market equilibrium with partially attentive investors, we examine the effects of...
