Product market power provides firms with comparative advantages through more persistent profitability and insulation from competitive threats. These advantages likely provide firms with the ability to engage in greater tax avoidance. We present evidence consistent with this hypothesis. We also show that firms mimic the tax outcomes of their product market leaders. Among firms with greater product market power and comparatively high cash tax avoidance, we find stock prices to be less informative and that investors require additional compensation for the risks associated with comparatively high cash tax avoidance. Our results survive numerous robustness tests. Overall, our results suggest that industry dynamics, particularly related to a firm's competitive position, play a meaningful role in corporate tax policy.

This study investigates the effect of firms' adoption of SFAS No. 131 segment disclosure rules on the stock market's ability to predict the firms' earnings, as captured by the forward earnings response coefficient (FERC). The FERC is the association between current-year returns and next-year earnings. SFAS No. 131, effective for fiscal years beginning after December 15, 1997, arguably increased both the quantity and quality of segment disclosure. Consistent with the standard's intended qualitative effects, pre-131 multi-segment firms experienced a significant increase in FERC after adopting SFAS No. 131. Consistent with the standard's intended quantitative effects, many pre-131 single-segment firms began disclosing multiple segments, and those that did experienced an increase in FERC. However, pre-131 single-segment firms that remained single segment (i.e., were unaffected by SFAS No. 131) had no change in FERC, indicating that the increase in FERC for 131-affected firms is not due to some other event concurrent to the adoption of SFAS No. 131. These results are robust under numerous procedures that control for characteristics of the sample firms and their earnings, providing strong evidence that SFAS No. 131 resulted in an increase in stock price informativeness for affected firms. Thus, we provide the first empirical price-based evidence that SFAS No. 131 provided more information (about future earnings) to the market, as the standard's proponents have suggested.

We examine the number of external appointments held by corporate directors. Directors who serve larger firms and sit on larger boards are more likely to attract directorships. Consistent with Fama and Jensen (1983), we find that firm performance has a positive effect on the number of appointments held by a director. We find no evidence that multiple directors shirk their responsibilities to serve on board committees. We do not find that multiple directors are associated with a greater likelihood of securities fraud litigation. We conclude that the evidence does not support calls for limits on directorships held by an individual.

This study examines differences in finance research productivity and influence across 661 academic institutions over the five year period from 1989 through 1993. We find that 40 institutions account for over 50% of all articles published by 16 leading journals over the five year period; 66 institutions account for two-thirds of the articles. Influence is more skewed with as few as 20 institutions accounting for 50% of all citations to articles in these journals. The number of publications and publication influence increase with faculty size and academic accreditation. Prestigious business schools are associated with high publication productivity and influence.

Using end‐of‐month bid‐ask spreads for 540 NYSE stocks over the period 1982–1987, we document a seasonal pattern in which both relative and absolute spreads decline from the end of December to the end of the following January. Cross‐sectional regressions do not, however, provide evidence of a significant correlation between changes in spreads at the turn of the year and January stock returns. Either there is no cause and effect relation between the coincidental seasonals in bid‐ask spreads and January returns for NYSE stocks or the data are too “noisy” to reveal any relation.

We estimate and compare a variety of continuous‐time models of the short‐term riskless rate using the Generalized Method of Moments. We find that the most successful models in capturing the dynamics of the short‐term interest rate are those that allow the volatility of interest rate changes to be highly sensitive to the level of the riskless rate. A number of well‐known models perform poorly in the comparisons because of their implicit restrictions on term structure volatility. We show that these results have important implications for the use of different term structure models in valuing interest rate contingent claims and in hedging interest rate risk.
