Independent of the left-right model of ideological structure, genetically modified organisms (GMOs) in food and agriculture are resented across the political spectrum in Switzerland. In the absence of any real experience with genetically modified (GM) food but faced with continuous exposure to...

We contrast a standard deterministic signaling game with a variant where the signal-generating mechanism is subject to stochastic perturbations. In the theoretical part, we obtain a unique equilibrium with stochastic signals. This equilibrium is separating and has intuitive comparative-static...

Travelers have to handle with various risks and uncertainties by themselves or they can ask a travel agent to act on their behalf in order to minimize and/or to solve them. We believe that the new nature of the activities that could be offered by the travel agencies would rather be a risk...

Does risk attitude (aversion or attraction) vary with the level of the income at risk? About half of our subjects chose to insure all levels, whereas another half chose instead not to insure low levels, but to insure high levels

There is no doubt that the current century is an era of environmental awareness which will require meeting the growing demands by means of a set of generating technologies, while minimising Greenhouse Gas emissions. Provided that technologies alone could not solve the problem, we have integrated...

This paper examines the role of other-regarding and time preferences for cooperation in the field. We study the preferences of fishermen whose main, and often only, source of income stems from using a common pool resource (CPR). The exploitation of a CPR involves a negative interpersonal and...

We investigate to what extent genuine social preferences can explain observed other-regarding behavior. In a social dilemma situation (a dictator game variant), people can choose whether to learn about the consequences of their choice for the receiver. We find that a majority of the people that...

We evaluate the impact of technology adoption subsidies on investment behavior in an individual choice experiment. In a laboratory setting professional managers are confronted with an intertemporal decision problem in which they have to decide whether or not to search for, and possibly adopt, a...
