We analyze a situation where a Principal does not necessarily have all the bargaining power while negotiating a contract with an Agent by studying a dynamic multi-objective moral hazard model with hidden action. We .nd that the structure of the optimal contracts change along the Pareto Frontier,...

We analyse a simple model of dynamic moral hazard in which there is a clear and tractable trade-off between static and dynamic incentives. In our model, a principal wants an agent to complete a project. The agent undertakes unobservable effort, which affects in each period the probability that...

In many industries like management consulting, IT consulting, or construction highly qualified employees, i.e., experts or executive managers, have to be assigned to temporary projects. In firms with many employees and various different projects, this assignment decision involves a complex...
