We document strong evidence of a declining relation between R&D and future profitability, which coincides with a number of important economic changes including a significant increase in R&D spending. We identify several contributors to this decline, including changes in the nature and riskiness...

We examine how shocks to perceived accounting quality lead to market prices that reflect an increased weight on prior disclosures of insider trading. We use a sample of firms where industry peers have restated financial information and find that the short-term market reaction to announcements of...

We examine the disclosure of non-GAAP earnings information in quarters containing transitory gains to investigate whether the primary motivation for these managers to disclose non-GAAP earnings is to inform or mislead. In this setting, non-GAAP earnings are more informative than GAAP earnings,...

We investigate the change in the aggregate earnings-returns relation from negative to positive. We first identify a gradual structural break around the second quarter of 1991. We then find evidence of three contributing factors to the change in the relation. They are: i) an increase in the...

We examine whether differences in the accounting measurement of investment activities help explain the negative association between aggregate investments and future returns. We decompose aggregate investment activity into investments in tangible and intangible assets. We find that the previously...

We examine the association between disagreement and trading volume around news events using a novel measure of disagreement that overcomes two challenges Bamber et al. (2011) identify as facing earlier measures. Specifically, we measure disagreement based on heterogenous opinions about firm...

We investigate whether investor attention is associated with the pricing (and mispricing) of earnings news where investor attention is measured using social media activity. We find that high levels of investor attention are associated with greater sensitivity of earnings announcement returns to...

We investigate whether historical cost measurement of assets lowers the usefulness of DuPont analysis for investors. Because firms report assets at modified historical cost under US GAAP, accounting ratios can be biased upward when assets have appreciated. Thus, variation in asset turnover,...

Critics of short-selling argue that short-sellers amplify price declines by targeting firms with falling prices in an unwarranted manner. Contrary to this viewpoint, we find that increases in short-interest for firms following a price decline are associated with measures of overpricing based on...

This study contributes to the body of research that examines the valuation of initial public offers (IPOs). The aim of this study is to assess the relative predictive ability of residual income valuation against the popular alternative of comparable firm valuation for predicting the offer prices...
