We document that forced resignations of top managers are preceded by large and significant declines in operating performance and followed by large improvements in performance. However, forced resignations are rare and are due more often to external factors (e.g., blockholder pressure, takeover attempts, etc.) than to normal board monitoring. Following the management change, these firms significantly downsize their operations and are subject to a high rate of corporate control activity. Normal retirements are followed by small increases in operating income and are also subject to a slightly higher than normal incidence of postturnover corporate control activity.

We provide evidence on the agency cost explanation for corporate diversification. We find that the level of diversification is negatively related to managerial equity ownership and to the equity ownership of outside blockholders. In addition, we report that decreases in diversification are associated with external corporate control threats, financial distress, and management turnover. These findings suggest that agency problems are responsible for firms maintaining value‐reducing diversification strategies and that the recent trend toward increased corporate focus is attributable to market disciplinary forces.

Using a sample of 44,288 firm‐ears between 1984 and 1997, we document an increase in the extent of global diversification over time. This trend does not reflect a substitution of global for industrial diversification. We also find that global diversification results in average valuation discounts of approximately the same magnitude as those for industrial diversification. Analysis of the changes in excess value associated with changes in diversification reveals that increases in global diversification reduce excess value, while reductions in global diversification increase excess value. These findings support the view that the costs of global diversification outweigh the benefits.

S&P 500 Index Additions and Earnings Expectations

Stock price increases associated with addition to the S&P 500 Index have been interpreted as evidence that demand curves for stocks slope downward. A key premise underlying this interpretation is that Index inclusion provides no new information about companies' future prospects. We examine this premise by analyzing analysts' earnings per share (eps) forecasts around Index inclusion and by comparing postinclusion realized earnings to preinclusion forecasts. Relative to benchmark companies, companies newly added to the Index experience significant increases in eps forecasts and significant improvements in realized earnings. These results indicate that S&P Index inclusion is not an information‐free event.
