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...

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...

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,...

In early 2019, the stock prices of the German company Wirecard AG experienced market turmoil after several critical reports on activities claimed to be illegal. To analyze the market impact of news, we use stock price data for Wirecard AG and apply the reversed news model. We elaborate on...

stock market crash on hedging strategies by portfolio insurers, which dictated selling stocks as soon as prices fell. The fact that the practice of buying and selling stocks as portfolio insurance has virtually disappeared since then has given many comfort that a replay of the 1987 crash, when...

We solve and test experimentally a global-games model of speculative attacks where agents can choose whether to read, at a cost, a payoff irrelevant (sunspot) announcement. Assuming that subjects exogenously believe some others to follow sunspots, we provide conditions for a unique equilibrium...

We use a model with agency frictions to analyze the structure of a dealer market that faces competition from a crossing network. Traders are privately informed about their types (e.g. their portfolios), which is something the dealer must take into account when engaging his counterparties....

Models to the issue of altruism which rely on externalities of well-being are rarely used explicitly. In this paper we compare such utility-based approaches with the standard approach on altruism which is based on externalities of income. Testable differences of both types of models are derived...

We empirically examine the efficacy of various incentives of microlending contracts such as joint-liability or group access to future loans. We find that joint liability induces a group formation of low risk borrowers. Furthermore, the incentive system leads to peer measures between the...
