Many experimental studies implement two versions of one game for which agents’ behavior is fundamentally different even though the Nash prediction is the same. This paper provides a novel explanation of such findings. Starting from the observation that many of the games under consideration...

Higher-dimensional symmetric games become of more and more importance for applied micro- and macroeconomic research. Standard approaches to uniqueness of equilibria have the drawback that they are restrictive or not easy to evaluate analytically. In this paper I provide some general but...

Politik und öffentliches Bewusstsein werden zunehmend durch ökonomische Theorien und Handlungsvorschläge mitbestimmt. Kaum ein anderes erkenntnis- und handlungsleitendes Modell hat daher einen vergleichbaren Einfluss wie das Konzept des Homo Oeconomicus. Durch die Entwicklung experimenteller...

Traditionally, economists make a sharp distinction between stated and revealed preferences, viewing the latter as more fully meeting the assumptions of economic analysis. Here, we consider one form of empirical evidence regarding this belief: the consistency of choices in stated and revealed...

We modify the provision point mechanism by introducing reward money, which is distributed among the contributors in proportion to their contributions only when the provision point is not reached. In equilibrium, the provision point is always reached as competition for reward money and preference...

States are ill equipped to meet the challenges of a globalized world. The concept of citizenship with its rights and obligations, including the allegiance owed, is too narrowly defined to exist only between individuals and a state. Today, people identify with, and pay allegiance to, many...

Rational Choice Theory is often criticized to indoctrinate students in a negative, which is supported by some laboratory experiments. But do students of Rational Choice Theory really behave more selfishly? This paper presents evidence from a natural decision on voluntary donation at the...

In November 2005, 55.7 percent of 2 million Swiss voters approved a 5-year moratorium (ban) on the commercial cultivation of genetically modified (GM) plants within Switzerland. The present study examines how individual voting decisions were determined by (i) socioeconomic characteristics, (ii)...

After several decades of academic research on the contingent valuation (CV) method a consistent behavioral explanation of 'hypothetical bias' is still lacking. Based on evidence from economics, economic psychology and the political sciences, I propose an explanation that is based on two simple...

Globalization is often seen to result in a smaller (Liliput) or larger (Leviathan) state. But future public activity will be more flexible. Persons have multiple identities. They can be citizens of sub- and supra-national jurisdictions, semi- and non-governmental organizations and private units,...
