When using the strategy method in ultimatum bargaining, many researchers ask responders for the minimal acceptable offer only implicitly assuming strategies to be monotone. Recent research has shown, however, that subjects decline disadvantageous and advantageous proposals. We report on an...

Psychological game theory can provide rational-choice-based framing effects; frames influence beliefs, beliefs influence motivations. We explain this theoretically and explore empirical relevance experimentally. In a 2×2 design of one-shot public good games we show that frames affect...

In a contest players compete for winning a prize by effort and thereby increasing their probability of winning. Contestants, however, could also improve their own relative position by harming the other players. We experimentally analyze contests with heterogeneous agents who may individually...

In the economic literature on market competition, firms are often modeled as single decision makers and the internal organization of the firm is neglected (unitary player assumption). However, as the literature on strategic delegation suggests, one can not generally expect that the behavior of...

We report a new method for Experimenting over a Long Distance (ELD)allowing to simultaneously run decentralized interactive experiments in geographically separated subject pools. Applying ELD to an intercultural trust experiment with participants from Argentina, China and Germany we found a...

We use an experiment to explore how subjects learn to play against computers which are programmed to follow one of a number of standard learning algorithms. The learning theories are (unbeknown to subjects) a best response process, fictitious play, imitation, reinforcement learning, and a trial...

Psychological game theory can provide a rational choice explanation of framing effects; frames influence beliefs, and beliefs influence motivations. We explain this point theoretically, and explore its empirical relevance experimentally. In a 2×2-factorial framing design of one-shot public good...

This paper introduces a two-sided methodological framework for studies on cooperation based on a new game design. Presented games are continuous prisoner's dilemma games with positive and negative presentations of an identically structured decision problem. Decision makers can choose an...

This paper investigates the impact of game presentation dependent on ethnical affiliation. Two games representing the same logical and strategical problem are introduced. Presented games are continuous prisoner’s dilemma games where decision makers can choose an individual level of cooperation...
