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...

In this study, we build a novel comprehensive dataset of 123,545 product trademark registrations by S&P 1500 firms to capture firm-level product development. We provide evidence that new product development contains valuable information about future firm fundamentals and predicts increases in...

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...

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...

We test whether and how equity overvaluation affects corporate financing decisions using an ex ante misvaluation measure that filters firm scale and growth prospects from market price. We find that equity issuance and total financing increase with equity overvaluation; but only among overvalued...

We investigate whether and when firms manage the tone of words in earnings press releases, and how investors react to tone management. We estimate abnormal positive tone, ABTONE, as a measure of tone management from residuals of a tone model that controls for firm quantitative fundamentals such...

Sometimes resources are badly employed because of coordination failures. Actions by decisionmakers that affect the likelihood of such failures cause ‘systemic risk.' We consider here the externality in the choice of ex ante risk management policies by individuals and firms: they are concerned...

We investigate whether non-audit service (NAS) purchases are correlated among audit committee (AC) interlocked firms. We then examine whether financial reporting quality and future firm performance vary with the amount of correlated NAS purchases from the AC interlock. We find that firms in the...

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...

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,...
