Zwei Theoretiker deduzieren widersprüchliche theoretische Aussagen und erzeugen einen Konflikt. Beide werden nun in einer Höhle eingesperrt (Empirieaussperrung). Kann durch die theoretische Diskussion der beiden die Wissenschaft fortschreiten? Die Theoretiker können verfolgen, woher der...

Die Ökonomische Theorie des Haftungsrechts kommt zu dem Ergebnis, daß Haftungsregeln unter bestimmten Bedingungen dazu geeignet sind, externe Effekte zu internalisieren. Die allokativen Wirkungen von verschiedenen Haftungsregeln wurden in Deutschland insbesondere vor dem Hintergrund der...

To explain the strategic dimension in pricing options, it will be helpful to go back to the heart of the idea behind the concept of an option: options open up the possibility to postpone current decisions to a future point of time. Because of this flexibility additional information and new...

This paper presents a non-monotonic relationship between foreign direct investment and trade based on the idea that, although FDI eliminates trade costs on the final good, the investing firm has to bear increased trade costs on an intermediate good.

We derive a class of utility functions that are equivalent with respect to a well-defined functional form. We study the case of constant relative risk aversion (of some order) to investigate on different equivalence relations in order to determine the, possibly infinite, number of equivalence...

The value at risk measure attempts to summarize in a single number market value risk of a portfolio of financial assets.The paper focuses on the interaction between the solvency probability of a bank, on one hand, and the diversification potential of its portfolio, on the other hand, when...

We analyse the role of bargaining centralisation when both the union's outside option and union membership are endogenous and considered in a dynamic framework. A dynamic two-sector model is developed where the wage rate in the first sector is either set by a monopoly union or is the result of...

We develop a general equilibrium model to study the transition from an established polluting to a new clean energy technology. Therefore, we consider two distinctive features: (i) the creation of new productive capital exhibits a timeto-build property, and (ii) the social and individual rates of...

We address the problem how to estimate default probabilities for sovereign countries based on market data of traded debt. A structural Merton-type model is applied to a sample of emerging market and transition countries. In this context, only few and heterogeneous default probabilities are...
