This paper studies the optimal contract offered by a risk-neutral principal to a risk-averse agent when the agent’s hidden efficiency and action both improve the probability of the project being successful. We show that if the agent is sufficiently prudent and efficient, the principal induces a higher probability of success than under moral hazard, despite the costly informational rent given up. Moreover, the conditions to avoid pooling are difficult to satisfy because of the different kinds of incentives to be managed and the overall trade-off between rent extraction, insurance, and efficiency involved.
