In this paper, I analyze the effects of monitoring on an agent?s incentives in a two-period principal-agent model in which the agent decides on his effort and corruptibility. The agent?s type and strategy are unknown to the principal.
I compare incentive-compatible wages under three different scenarios: when the principal does not monitor and only observes output; when she monitors the agent?s effort choice; and when she monitors the agent?s corruptibility.
