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...

It is a well-known phenomenon that people tend to overestimate their relative abilities. Psychological studies show that a vast majority of people thinks that their ability is above the average when they have to assess their position in a distribution of a target group. We analyse in an...

To investigate the influence of performance differences on donating behavior in a solidarity game we introduce a real effort task. In each three-person-group subjects are ranked according to their task performance. Since each potential winner is informed about his own rank and the potential...

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 experiment explores whether individuals know that other people are biased. We confirm that overestimation of abilities is a pervasive problem, but observe that most people are not aware of it, i.e. they think others are unbiased. We investigate several explanations for this result. As a...

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...

We analyze a two-stage game between two heterogeneous players. At stage one, common risk is chosen by one of the players. At stage two, both players observe the given level of risk and simultaneously invest in a winner-take-all competition The game is solved theoretically and then tested by...

Our experiment investigates managers’ self-predictions of their subsequent performance and, based upon, their choice of a collaborator. Our results show that managers’ self-predictions are not biased anymore after they are informed about the performance of a reference group. In spite of...

We propose an experimental method to test individuals for prudence (i.e. downside risk aversion) outside the expected utility framework. Our method relies on a novel representation of compound lotteries which allows for a systematic parameterization that captures the full generality of prudence....

In this paper we introduce four new learning models: impulse balance learning, impulse matching learning, action-sampling learning, and payoff-sampling learning. With this models and together with the models of self- tuning EWA learning and reinforcement learning, we conduct simulations over 12...
