The QALY concept is the commonly used approach in research to evaluate the efficiency of therapies in cost utility analysis. We investigate the risk neutrality assumption for time of the QALY concept: can time be included as a linear factor? Various studies show that this assumption does not...

This paper investigates the processing of repeated complex information. The focus of this study is whether additional information and the introduction of performance-based payoffs have an influence on judgment. Therefore, an experiment is designed to investigate the degree of precision and of...

While experimental research on social dilemmas focuses on the distribution of gains, we analyze social preferences in the case of losses. In this experimental study, the participants share a loss in a Nash bargaining game, but waiting time, instead of monetary losses, serves as an incentive....

Complexity of strategies is central for human decision making and attracted interest of different game theorists in the recent years. Nevertheless, behavioral economists have neglected the importance of complexity in their analyses. In this paper, we analyze network formation and action...

This paper presents results from an experiment designed to study the effect of self reporting risk preferences on strategy choices made in a subsequently played 2× 2 coordination game.The main finding is that the act of answering a questionnaire about one's own risk preferences significantly...

This paper presents the results of an experiment designed to study the effect produced on strategy choices when a subject reports risk preferences on a risk scale before engaging in a 2x2 coordination game. The main finding is that the act of stating one's own risk preferences significantly...

This paper experimentally examines the relationship between self-reporting risk preferences and behavioral choices in the subsequently played dictator, ultimatum and investment games. The results from these experiments are used to discern the motivational bases of behavioral choices in the...

This paper experimentally examines the efficiency of information aggregation in a simple asset market. Traders decide how to allocate an endowment of 1000 eurocent between two assets. Only one asset will be successful and that will pay back the amount invested in it. The experiment carried out...
