Holmström (1979) provides a condition for a signal to have positive value assuming the validity of the first-order approach. This paper extends Holmström's analysis to settings where the first-order approach may not hold. We provide a new condition for a signal to have positive value that...

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...

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...
