This paper develops and tests the uncertain information hypothesis as a means of explaining the response of rational, risk-averse investors to the arrival of unanticipated information. The theory predicts that following news of a dramatic financial event, both the risk and expected return of the affected companies increase systematically, and that prices react more strongly to bad news than good. An empirical investigation of over 9000 marketwide and firm-specific events produces results consistent with these predictions. We conclude that the market reacts to uncertain information in an efficient, if not instantaneous, manner.

We examine the form, adoption rates, and economic rationale for various mutual fund investment restrictions. A sample of U.S. domestic equity funds from 1994 to 2000 reveals systematic patterns in investment constraints, consistent with an optimal contracting equilibrium in the fund industry. Restrictions are more common when (i) boards contain a higher proportion of inside directors, (ii) the portfolio manager is more experienced, (iii) the fund is managed by a team rather than an individual, and (iv) the fund does not belong to a large organizational complex. Low- and high-constraint funds produce similar risk-adjusted returns, also consistent with an optimal contracting equilibrium.

Corporate Governance, Incentives, and Industry Consolidations Several changes, such as the advances in information technology and the advent of outsourcing, led to increases in optimal firm size in many fragmented industries over the last decade. This paper studies the determinants of the success of these industry consolidations using a unique sample of firms that were created at the time of their initial public offering: rollup-up IPOs. In these transactions, many small firms merge into a shell company, which goes public at the same time. This sample allows us to follow firms from the day they were established. We find that these firms deliver poor absolute and relative stock returns, on average. Their operating performance mimics that of other firms of the industry, but does not justify to their high initial valuations. However, the average performance hides substantial cross-sectional differences. If

The authors test the hypothesis that, when their compensation is linked to relative performance, managers of investment portfolios likely to end up as 'losers' will manipulate fund risk differently than those managing portfolios likely to be 'winners.' An empirical investigation of the performance of 334 growth-oriented mutual funds during 1976 to 1991 demonstrates that mid-year losers tend to increase fund volatility in the latter part of an annual assessment period to a greater extent than mid-year winners. Furthermore, the authors show that this effect became stronger as industry growth and investor awareness of fund performance increased over time.

We test the hypothesis that when their compensation is linked to relative performance, managers of investment portfolios likely to end up as “losers” will manipulate fund risk differently than those managing portfolios likely to be “winners.” An empirical investigation of the performance of 334 growth‐oriented mutual funds during 1976 to 1991 demonstrates that mid‐year losers tend to increase fund volatility in the latter part of an annual assessment period to a greater extent than mid‐year winners. Furthermore, we show that this effect became stronger as industry growth and investor awareness of fund performance increased over time.
