We propose a theory based on investor overconfidence and biased self-attribution to explain several of the securities returns patterns that seem anomalous from the perspective of efficient markets with rational investors. The theory is based on two premises derived from evidence in psychological...

We propose that CEO exploratory mindset—inherent desire to search for novel ideas and long-term orientation—promotes innovation. Firms with PhD CEOs produce more exploratory patents with greater novelty, generality and originality. PhD CEOs engage less in managing earnings and stock prices,...

A manager who wants to be viewed favorably has an incentive to advance or delay the arrival of information about his firm's profitability. In the model, a high ability manager tries to advance resolution of a likely-favorable outcome, while a low ability manager may defer resolution. Such...

This paper models how imperfect memory affects the optimal continuity of policies. We examine the choices of a player (individual or firm) who observes previous actions but cannot remember the rationale for these actions. In a stable environment, the player optimally responds to memory loss with...

We analyze capital allocation in a conglomerate where divisional managers with uncertain abilities compete for promotion to CEO. A manager can sometimes gain by unobservably adding variance to divisional output. Capital rationing can limit this distortion, increase productive efficiency, and...

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,...

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...

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...

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...

We examine how investor preferences and beliefs affect trading in relation to past gains and losses. The probability of selling as a function of profit is V-shaped; at short holding periods, investors are more likely to sell big losers than small ones. There is little evidence of an upward jump in...
