I study a dynamic principal agent model in which the effort cost of the agent is unknown to the principal. The principal is ambiguity averse, and designs a contract which is robust to the worst case effort cost process. Ambiguity divides the contract into two regions. After sufficiently high...

I study when a firm prefers to be transparent about pay using a simple multidimensional signaling model. Pay transparency within the firm means that a worker can learn about his own worker-firm match from another worker's pay. This can either encourage or discourage workers – which affects...

This paper addresses the question, what metrics should be used for performance evaluation and in particular how they should be weighted and combined in the presence of technological interdependencies when the agents exhibit variedly strong developed rivalry. We find that the principal reacts to...

This paper analyzes the impact of heterogeneous (social) preferences on the weighting and combination of performance measures as well as on a firm’s profitability. We consider rivalry, egoism and altruism as extreme forms within the continuum of possible preferences and show that the principal...

Consider managers evaluating their employees\' performances. Should managers justify their subjective evaluations? Suppose a manager\'s evaluation is private information. Justifying her evaluation is costly but limits the principal\'s scope for distorting her evaluation of the employee. I show...

When designing incentives for a manager, the trade-off between insuranceand a “good” allocation of effort across various tasks is oftenidentified with a trade-off between the responsiveness (sensitivity, precision,signal-noise ratio) of the performance measure and its similarity(congruity,...

I study the optimal choice of investment projects in a continuous time moral hazard model with multitasking. While in the first best, projects are invariably chosen by the net present value (NPV) criterion, moral hazard introduces a cutoff for project execution which depends on both a project's...

Wir analysieren das Gesetz zur Angemessenheit der Vorstandsvergütung. Ferner arbeiten wir einige aufgrund wirtschaftswissenschaftlicher Überlegungen zu erwartende Probleme heraus und prognostizieren mögliche ökonomische Auswirkungen des Gesetzes. Des Weiteren gehen wir im Rahmen einer...

In markets with quality unobservable to buyers, third-party certification is often the only instrument to increase transparency. While both sellers and buyers have a demand for certification, its role differs fundamentally: sellers use it for signaling, buyers use it for inspection. Seller...

In the model there are two types of financial auditors with identical technology, one of which is endowed with a prior reputation for honesty. We characterize conditions under which there exists a "two-tier equilibrium" in which "reputable" auditors refuse bribes offered by clients for fear of...
