How do people trade off efficiency against equality concerns? To study this question, we conducted a modified mini ultimatum game (N=120) in which proposers were asked to choose between offering 8:2 and y:y, y∈{5, 4.5, 4,.., 0.5}; all offers in Euro. According to the data, 58 of 60 proposers...

We assess the empirical validity of the overall theoretical framework of other-regarding preferences by focusing on those preference axioms that are common to all the prominent theories of outcome-based other-regarding preferences. This common set of preference axioms leads to a testable...

Participants in experimental games typically can only choose actions, without making comments about other participants' future actions. In sequential two-person games, we allow first movers to express a preference between responder choices. We find that responder behavior differs substantially...

Supporters of left-wing parties typically place more emphasis on redistributive policies than right-wing voters. I investigate whether this difference in tolerating inequality is amplified by suspicious success - achievements that may arise from cheating. Using a laboratory experiment, I...

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...

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...
