We develop a stylized principal-agent model with moral hazard and adverse selection to provide a unified framework for understanding some of the most salient features of the recent physician payment reform in Ontario and its impact on physician behavior. These features include: (1) physicians...

While most market transactions are subject to strong incentives, transactions within firms are often not incentivized. We offer an explanation for this observation based on envy among agents in an otherwise standard moral hazard model with multiple agents. Envious agents suffer if other agents...

Consider a principal-agent relationship in which more effort by the agent raises the likelihood of success. Does rewarding success, i.e., paying a bonus, increase effort in this case? I find that bonuses have not only an incentive but also an income effect. Overall, bonuses paid for success may...

How can a manager influence workers' activity while knowing little about it? This paper examines a situation where production requires several tasks, and the manager wants to direct production to achieve a preferred allocation of effort across tasks. However, the effort that is required for each...

We analyze the optimal contract between a risk-averse manager and the initial shareholders in a two-period model where the manager's investment effort, carried out in period 1, and her current effort, carried out in period 2, both impact the second-period profit, so that it may be difficult to...

Unemployment insurance agencies may combat moral hazard by punishing refusals to apply to assigned vacancies. However, the possibility to report sick creates an additional moral hazard, since during sickness spells, minimum requirements on search behavior do not apply. This reduces the ex ante...

We analyze the optimal contract in static moral hazard situations, where the agent’s effort is not verifiable. We first present the main trade-offs of the principal-agent model. We cover the trade-off of incentives (motivation) vs. risk-sharing (efficiency), incentives vs. rents (when the...

We consider a two-stage principal-agent model with limited liability in which a CEO is employed as agent to gather information about suitable merger targets and to manage the merged corporation in case of an acquisition. Our results show that the CEO systematically recommends targets with low...
