We build a novel comprehensive dataset of new product trademarks as an output measure of product development innovation. We show that risk-taking incentives in CEO compensation motivate this type of innovation and that this innovation improves firm performance. Using an exogenous shock to...

We review here theory and evidence relating to herd behavior, 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,...

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,...

Investor attention is a limited resource. This chapter discusses the literature on investor limited attention and its effects on capital markets. Theoretical and empirical studies find that when some investors are inattentive, the immediate market reaction to news is incomplete and the price...

Psychological research suggests that communication using dynamic visuals attract higher attention and induce higher activation response than text and static images. Stocktwits is a social media platform where postings about a stock can include GIF images (henceforth GIFs) and declare their...

We test whether earnings management (like a virus) spreads from firm to firm via board connections of shared directors (virus carriers). We use earnings restatements to identify firms that managed earnings and to identify the period when these firms manipulated earnings. We consider firms as...

We offer here the psychological attraction approach to accounting and disclosure rules, regulation, and policy as a program for positive accounting research. We suggest that psychological forces have shaped and continue to shape rules and policies in two different ways. (1) Good Rules for Bad...

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...

Recent studies propose that limited investor attention causes market underreactions. This paper directly tests this explanation by measuring the information load faced by investors. The "investor distraction hypothesis" holds that extraneous news inhibits market reactions to relevant news. We...
