Indexfonds sind aufgrund ihrer Terminmarktgeschäfte mit Agrarrohstoffen ins Zentrum öffentlicher Aufmerksamkeit und Kritik geraten. Hierzu kursieren in den Medien zahlreiche Falschinformationen, deren Korrektur sich durch klar identifizierbare Forschungslücken der empirischen Literatur...

This study analyses the impact of the Russian food and agricultural import ban on import of meat, the structural changes of trade pattern and reallocation of import flows of meat and meat products, and the price development in the import market and its impact on producers and consumers market...

Landwirtschaftliche Erzeugnisse erreichen die Verbraucherinnen und Verbraucher in aller Regel in mehr oder weniger verarbeiteter Form, so dass im Endprodukt neben den Agrarrohstoffen noch andere Wertbestandteile enthalten sind. Angesichts der Herausforderungen, mit denen sich der Agrarsektor...

In this paper, I seek to establish a framework in which solutions to imperfect recall decision problems can be suitably examined. I introduce a strategy concept which is an extension of the standard concept employed since von Neumann and Morgenstern, and show how it may provide optimal solutions...

In this paper, I study decision theory in the presence of imperfect recall. I use an extension of the standard strategy concept for the analysis of extensive form games in order to examine the range of imperfect recall problems for which there exists an optimal solution. Optimality is assessed...

In this study we introduce a new stochastic choice rule that categorizes objects in order to simplify the choice procedure. At any given trial, the decision maker deliberately randomizes over mental categories and chooses the best item according to her utility function within the realized...

We develop a general framework to study contests, containing the well-known models of Tullock (1980) and Lazear & Rosen (1981) as special cases. The contest outcome depends on players' effort and skill, the latter being subject to symmetric uncertainty. The model is tractable, because a...

Whereas many others have scrutinized the Allais paradox from a theoretical angle, we study the paradox from an historical perspective and link our findings to a suggestion as to how decision theory could make use of it today. We emphasize that Allais proposed the paradox as a normative argument,...
