In the last decades, there has been a large volume of research showing that emotions do have relevant effects on decision-making. We contribute to this literature by experimentally investigating the impact of four specific emotional states - joviality, sadness, fear, and anger - on risk...

We study the existence of homophily (i.e. the tendency for people to make friends with people who are similar to themselves) with respect to trustworthiness. We ask whether two friends show similarly trustworthy behavior towards strangers, and whether this is anticipated by outsiders. We develop...

Concessions try to avoid conflict in bargaining and can finally lead to an agreement. Although they usually are seen as unfolding in time, concessions can also be studied in normal form or by conditioning only on failure of earlier agreement attempts. We experimentally compare three protocols of...

Meta-regression models are increasingly utilized to integrate empirical results across studies while controlling for the potential threats of data-mining and publication bias. We propose extended meta-regression models and evaluate their performance in identifying genuine empirical effects by...

Experimental studies of the WTP-WTA gap avoid social trading by implementing an incentive compatible mechanism for each individual trader. We compare a traditional random price mechanism and a novel elicitation mechanism preserving social trading, without sacrificing mutual incentive...

Policy makers constantly face optimal control problems: what controls allow to achieve certain targets in, e.g., GDP growth or inflation? Conventionally this is done by applying certain linear-quadratic optimization algorithms to dynamic econometric models. Several algorithms extend this...

For games of simultaneous action selection and network formation, game-theoretic behavior and experimental observations are not in line: While theory typically predicts inefficient outcomes for (anti-)coordination games, experiments show that subjects tend to play efficient (non Nash) strategy...

The impact that the retail format has on the level of individual motivation tends to be overlooked in discussions of the determinants of organic consumption, this neglect due to the tendency to model individual and contextual factors separately. Hence, the dominant research paradigm has...

In many different contexts individuals take decisions on the behalf of others. However, little is known about how this circumstance affects the decision making process and influences the ultimate individuals´ choices. In this paper, we focus on the context of investment decisions and study if...

Two pairs of two participants each interact repeatedly in two structurally independent but informationally linked Prisoner´s Dilemma games. Neither pair receives feedback about past choices by their own partner but is fully informed about the choices by the other pair. Considering this as a...
