Firms with central boards of directors earn superior risk-adjusted stock returns. A long (short) position in the most (least) central firms earns average annual returns of 4.68%. Firms with central boards also experience higher future return-on-assets growth and more positive analyst forecast errors. Return prediction, return-on-assets growth, and analyst errors are concentrated among high growth opportunity firms or firms confronting adverse circumstances, consistent with boardroom connections mattering most for firms standing to benefit most from information and resources exchanged through boardroom networks. Overall, our results suggest that director networks provide economic benefits that are not immediately reflected in stock prices.

We examine the relation between firms' voluntary guidance and mandatory 8K filings. We find a negative relation between guidance and 8Ks, which strengthens following the 2004 expansion of mandatory 8K requirements, consistent with firms using the disclosures as substitutes. Increases in 8Ks coincide with declines in firms’ profits, but this negative relation weakens after the 2004 regulation, consistent with firms broadening the scope of information conveyed through 8Ks. Together, our findings suggest firms became more reliant on 8Ks to convey general types of information after the 2004 regulation, rather than primarily negative news, which reduces their incentives to issue guidance.

Much of capital market research in accounting over the past 20 years has assumed that the price adjustment process to information is instantaneous and/or trivial. This assumption has had an enormous influence on the way we select research topics, design empirical tests, and interpret research findings. In this discussion, I argue that price discovery is a complex process, deserving of more attention. I highlight significant problems associated with a naı̈ve view of market efficiency, and advocate a more general model involving noise traders. Finally, I discuss the implications of recent evidence against market efficiency for future research.

This study separates trading volume into buyer- and seller-initiated activities and examines the directional volume reaction in small and large trades to different types of earnings news. ‘Good’ (‘bad’) news triggers brief, but intense, buying (selling) in the large trades. However, a persistent period of unusually high buying activity is observed in the small trades irrespective of the news. This anomalous proclivity of small traders to buy is robust across firm size, trading volume, and different earnings expectation models. Several explanations are discussed, although the behavior does not seem fully explained by existing theories.

We identify a new channel – market makers' attention constraints – through which earnings announcements for one stock affect the liquidity of other stocks. When some stocks handled by a designated market maker have earnings announcements, liquidity is lower for non-announcement stocks handled by the same market maker, with the largest effects coming from earnings surprises and stocks with high earnings response coefficients. Half of the liquidity decline reflects attention constraints binding on the individual market maker, and the other half is explained by the market maker's inventory. We further find that a market design change that increases automation alleviates the liquidity effect of attention constraints, despite an increase in the number of stocks allocated to each market maker.

This paper provides evidence that repurchase tender offer announcements convey favorable information about the level and riskiness of future earnings. We show that analysts revise their forecasts of earnings per share upward following repurchase announcements. Repurchase announcement stock price reactions are positively correlated with revisions in short-term forecasts, but not correlated with revisions in long-term forecasts. Thus, the information is primarily about transitory changes in earnings. We also provide evidence that equity betas decline after repurchases. Our findings indicate that the equity beta decreases are due to decreases in the underlying riskiness of the firm's assets.

Using hand-collected data on analyst locations, we study how geographic proximity affects analyst coverage decisions for U.S. firms that went public during 1996–2009, along with the impact of local coverage on firm visibility. Analysts are 80% more likely to cover local firms than non-local ones, and nearby non-underwriter analysts initiate coverage one to three weeks earlier than distant ones. Proximity matters most for smaller, less visible firms, for firms with less complex operations and for lower status analysts. Less visible firms may use local analyst coverage as a stepping-stone to increase visibility with other analysts and institutional investors.

We study management turnover for the top five executives in a sample of 443 large firms from 1993 through 1998. The rate of forced turnover for non-CEOs is at least as great as that for CEOs, but the sensitivity of turnover to firm performance is smaller for non-CEOs. The probability that a non-CEO leaves office is elevated around CEO dismissals, particularly when the replacement CEO is an outsider. Many dismissed executives obtain new employment, but on average their new positions are significantly inferior to their prior jobs. Labor market outcomes are related to past compensation and the circumstances around departure.

This study examines the association between stock returns and foreign GAAP earnings versus earnings adjusted to U.S. GAAP. Using a sample of foreign firms with common stock or American Depositary Receipt (ADR) traded in U.S. exchanges, we compare the returns-earnings relations between U.S. and foreign GAAP-based earnings. Results based on the JA test indicate that earnings based on foreign GAAP are more closely associated with contemporaneous stock returns than earnings reconciled to U.S. GAAP. We find evidence that our results may be driven by institutional factors which are specific to foreign markets.

Diversified corporations have been widely criticized as being inefficient innovators with an orientation to maximizing short-term profits. This study investigates this criticism by testing whether the number of new products introduced per R&D dollar is lower among more diversified firms. We find no statistically discernible effect of diversification on innovative efficiency in a sample of 706 research-intensive firms in the 1981–1988 period. This suggests that diversified organizations are rationally designed to minimize incentive and communication problems which may hinder innovation. Consistent with this view, we find that diversified firms are more likely to have separate research and development centers.
