This paper studies the value of more precise signals on agent performance in an optimal contracting model with endogenous effort. With limited liability, the agent’s wage is increasing in output only if output exceeds a threshold, else it is zero regardless of output. If the threshold is sufficiently high, the agent only beats it, and is rewarded for increasing output through greater effort, if there is a high noise realization. Thus, a fall in output volatility reduces effort incentives—information and effort are substitutes—offsetting the standard effect that improved information lowers the cost of compensation. We derive conditions relating the incentive effect to the underlying parameters of the agency problem.

We find that CEOs release 20% more discretionary news items in months in which they are expected to sell equity, predicted using scheduled vesting months. These vesting months are determined by equity grants made several years prior and thus unlikely to be driven by the current information environment. The increase arises for positive news, but not neutral or negative news, nor nondiscretionary news. News releases fall in the month before and month after the vesting month. News in vesting months generates a temporary increase in stock prices and market liquidity, which the CEO exploits by cashing out shortly afterwards.
