Unternehmen müssen nicht immer Kollusionsabsichten verfolgen, wenn sie untereinander Informationen austauschen. Dieser Beitrag zeigt, daß bei Nachfrageunsicherheit auch strikt kompetitive Konkurrenten private Informationen bezüglich ihrer Nachfragebedingungen preisgeben. Dies läßt sich in...

This paper further develops the standard modelling of information exchange between firms in the presence of demand uncertainty which applies to firms in new industries and insecure regions or markets. We replace the normal distribution of the random variables, commonly used because of its...

We report and analyze the results of a series of classroom experiments on the voluntary provision of public goods. Using fixed effect panel regression models we find that cooperation significantly increases when participants are forced to guess the degree of overall cooperation. We also find...

This note focuses on the role of the planning horizon in monetary policy games. We analyze the case of an uncertain horizon of the monetary policy game that has not been considered, yet. In addition to that we will - different from the basic Barro-Gordon-model - assume a quadratic loss function...

This paper provides a simple model of repeated extortion. In particular, we ask whether corrupt government officials' ex post opportunism to demand more once entrepreneurs have made sunk investments entails further distortion in resource allocations. We show that the inability of government...

In this paper a discrete choice model is suggested which generates unambiguously lower prices, if oligopolists discriminate by price. In a setting of two groups of consumers and two firms this is due to a different ranking of the elasticity of demand of the two groups by the two firms. Here,...

Die Studie zeigt Handlungsfelder des Managements im Fußball auf. Sie versucht, die Entscheidungen des Managements mikroökonomisch und spieltheoretisch zu fundieren - mit dem Ziel, einige der mutmaßlichen Erfolgsfaktoren im Fußball zu identifizieren und ihre Wirkungsmechanismen zu erklären.

While most countries have harmonized intellectual property rights (IPR) legislation, the dispute about the optimal level of IPR-enforcement remains. This paper develops an endogenous growth framework with two open economies satisfying the classical North-South assumptions to study (a)...

In this paper, we extend the Fehr and Schmidt model of inequality aversion to a situation where the players differ with respect to their benefits and costs from contributions to a non-linear public good. A necessary condition for contributing to the public good is that the players' benefit...

In January 1995 Austria, Sweden, and Finland became member states of the European Union. All three countries have traditionally given comparatively high priority to environmental protection. This paper deals with the question of what influence the new members will have on environmental...
