We investigate the role of intentions in two-player two-stage games. For this purpose we systematically vary the set of opportunity sets the first mover can chose from and study how the second mover reacts not only to opportunities of gains but also of losses created by the choice of the first...

Delineation of someone's ownership typically involves the sense of deservedness: the property right is respected as long as the owner deserve to own the object. Objectively, deservedness is often linked to one's actions or specific attributes that justify the owner's claims. We argue that people...

Experimental literature on pro-social behavior has been largely focused on settings where the decision of donors is sufficient for an interaction to occur. However, in many real-life applications recipients first have to ask donors for help to initiate the transaction. We suggest that this first...

Although different approaches and methods have been used to measure inequality aversion, there remains no consensus about its drivers at the individual level. We conducted an experiment on a sample of more than 1800 first-year undergraduate economics and business students in Uruguay to...

In settings where other-regarding motives are likely to be (and some would argue, should be) at the forefront of our minds, how much of our behavior can still be explained by narrow pecuniary self-interest by itself? In an experiment where subjects are asked to vote between two income...

We study optimal direct mechanisms for a credence goods expert who can be altruistic or spiteful. The expert has private information about her distributional preferences and possibly also about her customer's needs. We introduce a method that allows the customer to offer separate contracts to...

Engelmann and Strobel (AER 2004) claim that a combination of efficiency seeking and minmax preferences dominates inequity aversion in simple dictator games. This result relies on a strong subject pool effect. The participants of their experiments were undergraduate students of economics and...

Engelmann and Strobel (AER 2004) question the relevance of inequity aversion in simple dictator game experiments claiming that a combination of a preference for efficiency and a Rawlsian motive for helping the least well-off is more important than inequity aversion. We show that these results...

This paper studies the evolution of both characteristics of reciprocity - the willingness to reward friendly behavior and the willingness to punish hostile behavior. Firstly, preferences for rewarding as well as preferences for punishing can survive evolution provided individuals interact within...
