We study the joint design of dynamic incentives and performance feedback for an environment with a coarse (all-or-nothing) measure of performance. Using a novel approach to incentive compatibility, we derive a two-phase solution that begins with a “silent phase” where the agent is given no feedback and is asked to work non-stop, and ends with a ”full-transparency phase” where the agent stops working as soon as a performance threshold is met. Hiding information leads to greater effort but comes at a cost because an ignorant agent is more expensive to motivate. The two-phase solution—where the agents ignorance is fully frontloaded—stems from a backward compounding effect that raises the cost of hiding information as time passes. When- ever the agent’s hazard rate of success falls sufficiently over time, the principal should eventually give up on them, as occurs in practice with up-or-out promotion policies.
