This paper shows that the informativeness principle does not automatically extend to settings with limited liability. Even if a signal is informative about effort, it may have no value for contracting. An agent with limited liability is paid zero for certain output realizations. Thus, even if these output realizations are accompanied by an unfavorable signal, the payment cannot fall further and so the principal cannot make use of the signal. Similarly, a principal with limited
liability may be unable to increase payments after a favorable signal. We derive necessary and su¢ cient conditions for signals to have positive value. Under bilateral limited liability and a monotone likelihood ratio, the value of information is non-monotonic in output, and the principal is willing to pay more for information at intermediate output levels.
This paper studies the corporate governance and asset pricing implications of investors owning blocks in multiple firms. Common wisdom is that multi-firm ownership weakens governance because the blockholder is spread too thinly. We show that this need not be the case. In a single-firm benchmark, the blockholder governs through exit, selling her stake if the firm underperforms. With multiple firms, the blockholder may sell even a value-maximizing firm, to disguise her exit from another underperforming firm as being motivated by a portfolio-wide liquidity shock. This reduces the manager's effort incentives and weakens governance. On the other hand, governance can be stronger, because selling one firm and not the other is a powerful signal of underperformance. Common ownership leads to firms' stock prices being correlated, even if their fundamentals are uncorrelated. We derive empirical predictions for the direction of correlation and for whether governance is stronger or weaker with multiple firms.
