We analyze a bargaining protocol recently proposed in the literature vis-à-vis unconstrained negotiation. This new mechanism extracts gains from trade inherent in the differing valuation of two parties towards various issues where conflict exists. We assess the role of incomplete vs. complete...

Should principals explain and justify their evaluations? In this paper the principal's evaluation is private information, but she can provide some justifications by sending a costly message. Indeed, it is optimal for the principal to explain her evaluation to the agent if and only if the...

In einem Ein-Perioden-Modell werden die Auswirkungen des deutschen Steuerrechts zur Kapitalbesteuerung auf das Kapitalmarktgleichgewicht untersucht. Dabei modellieren wir sowohl einen Unternehmenssektor, der der Körperschaftsteuer unterliegt, als auch Privatinvestoren, die...

This paper considers simultaneous modelling of seasonality, slowly changing un- conditional variance and conditional heteroskedasticity in high-frequency fiancial returns. A new approach, called a seasonal SEMIGARCH model, is proposed to perform this by introducing multiplicative seasonal and...

The behavior of a hedge-fund manager naturally depends on her compensation scheme, her preferences, and constraints on her risk-taking. We propose a numerical method which can be used to analyze the impact of these influences. The model leads to several interesting and novel results concerning...

The German Basic Law is open for an interpretation that would allow the Constitutional Court to test the normative adequacy of most statutes. If the court does, it could be modelled as the supervisor of the legislator, i.e., of the agent of the people. The model predicts collusion between the...
