Replication crisis and debates about p-values have raised doubts about what we can statistically infer from research findings, both in experimental and observational studies. With a view to the ongoing debate on inferential errors, this paper systematizes and discusses experimental designs with...

Besides the inferential errors that abound in the interpretation of p-values, the probabilistic pre-conditions (i.e. random sampling or equivalent) for using them at all are not often met by observational studies in the social sciences. This paper systematizes different sampling designs and...

Das Vertrauen der Bevölkerung gegenüber der Wissenschaft hängt in starkem Maß von der Art der Vermittlung wissenschaftlicher Erkenntnisse ab. Dabei ist es entscheidend, durch eine adäquate Interpretation statistischer Analysen eine vernünftige Bewertung der Zuverlässigkeit...

Experiments are often used to study individual decision‐making under controlled circumstances. Due to their low opportunity costs and high availability, university students are frequently recruited as the study population. Even though they are rather untypical with regard to many...

Wetterindexversicherungen stellen innovative Risikomanagementinstrumente dar und weisen gegenüber herkömmlichen Versicherungen den Vorteil geringer Administrations- und Regulierungskosten auf. Darüber hinaus entstehen keine Moral-Hazard- und Adverse-Selection-Probleme. In der Landwirtschaft...

It has often been noted that the "null-hypothesis-significance-testing" (NHST) framework is an inconsistent hybrid of Neyman-Pearson's "hypothesis testing" and Fisher's "significance testing" that almost inevitably causes misinterpretations. To facilitate a realistic assessment of the potential...

This paper gives an overview of simulation based procedures, which have proved to be efficient in valuing American options and therefore real options. Many of them integrate sequential stochastic simulations in the backward recursive programming approach to determine the early-exercise frontier....

Angesichts der wochenlangen Dürre in diesem Sommer stellt die Bundesregierung den besonders von Ernteausfällen betroffenen deutschen Landwirten Finanzhilfen in Höhe bis 170 Mio. Euro in Aussicht, falls sich die Bundesländer mit der gleichen Summe beteiligen. Nicht jeder sieht die Nothilfen,...

Eine Reihe von Lebensmittelskandalen der jüngeren Vergangenheit hat gezeigt, dass fehlgeleitete ökonomische Anreize eine bedeutsame Risikoquelle sind. Der Normappell des Gesetzes reicht augenscheinlich nicht bei allen Lebensmittelunternehmern aus, um sie von gewinnträchtigen Verstößen gegen...
