We find a positive association between short-selling and accruals during 1988-2003. Short arbitrage occurs primarily among firms in the top accrual decile, and firms with sufficiently high supply of loanable shares (proxied by institutional holdings). Consistent with limits to short arbitrage,...

Psychological evidence indicates that it is hard to process multiple stimuli and perform multiple tasks at the same time. This paper tests the INVESTOR DISTRACTION HYPOTHESIS, which holds that the arrival of extraneous news causes trading and market prices to react sluggishly to relevant news...

This paper explores whether and why misvaluation affects corporate investment by comparing tangible and intangible investments; and by using a price-based misvaluation proxy that filters out scale and earnings growth prospects. Capital, and especially R\&D expenditures increase with overpricing;...

Using options- and press-based proxies for CEO overconfidence (Malmendier and Tate 2005a, 2005b, 2008), we find that over the 1993-2003 period, firms with overconfident CEOs have greater return volatility, invest more in innovation, obtain more patents and patent citations, and achieve greater...

Past research has shown that the level of operating accruals is a negative cross-sectional predictor of stock returns. This paper examines whether the accrual anomaly extends to the aggregate stock market. In contrast with cross-sectional findings, there is no indication that aggregate operating...

We find a positive association between short-selling and accruals, and between short-selling and NOA, during 1988-2003. The accrual and NOA return anomalies are asymmetric. The absolute value of mean abnormal returns is larger for high-accrual firms than low-accrual firms on NASDAQ, but not on...

We document considerable return comovement associated with accruals after controlling for other common factors. An accrual-based factor-mimicking portfolio has a Sharpe ratio of 0.16, higher than that of the market factor or the SMB and HML factors of Fama and French (1993). In time series...

We review theory and evidence relating to herd behaviour, payoff and reputational interactions, social learning, and informational cascades in capital markets. We offer a simple taxonomy of effects, and evaluate how alternative theories may help explain evidence on the behavior of investors,...

In our model, informed players decide whether or not to disclose, and observers allocate attention among disclosed signals, and toward reasoning through the implications of a failure to disclose. In equilibrium disclosure is incomplete, and observers are unrealistically optimistic. Nevertheless,...

Prevailing models of capital markets capture a limited form of social influence and information transmission, in which the beliefs and behavior of an investor affects others only through market price, information transmission and processing is simple (without thoughts and feelings), and there is...
