There is little consensus on whether women are more generous than men; some research results indicate a higher propensity towards giving of female dictators, whilst others suggest the opposite. Two explanations have been put forward. According to the first one, women are more generous than men...

We study social preferences in the form of altruism using data on 959 interactions between random commuters at selected traffic intersections in the city of Brisbane, Australia. By observing real decisions of individual commuters on whether to stop (give way) for others, we find evidence of (i)...

Anti-Muslim prejudice is widespread in Western countries. Yet, Muslims are expected to constitute a growing share of the total population in Western countries over the next decades. This paper predicts that this demographic trend will increase anti-Muslim prejudice. Relying on experimental games...

Modeling the incentive effects of competitions among employees for promotions or financial rewards, economists have largely ignored the effects of competition on effort provision once the competition is finished. In a laboratory experiment, we examine how competition outcomes affect the...

We use a sequential prisoner's dilemma game to measure the other-regarding behavior in samples from three related populations in the upper Midwest of the United States: 100 college students, 94 non-student adults from the community surrounding the college and 1,069 adult trainee truckers in a...

We analyze the assimilation patterns of Muslim immigrants in Western countries with a unique identification strategy. Survey and experimental data collected in France in 2009 reveal that Muslims and rooted French are locked in a sub-optimal equilibrium whereby (i) rooted French exhibit...

Social preference research has received considerable attention among economists in recent years. However, the empirical foundation of social preferences is largely based on laboratory experiments with self-selected students as participants. This is potentially problematic as students...

Laboratory experiments are frequently used to examine the nature of individual preferences and inform economic theory. However, it is unknown whether the preferences of volunteer participants are representative of the population from which the participants are drawn or whether they differ due to...

Laboratory experiments have become a wide-spread tool in economic research. Yet, there is still doubt about how well the results from lab experiments generalize to other settings. In this paper, we investigate the self-selection process of potential subjects into the subject pool. We alter the...

Muslims do less well on the French labor market than their non Muslim counterparts. One explanation for this relative failure can be characterized by the following syllogism: (1) the empowerment of women is a sine qua non for economic progress; (2) in-group norms among Muslims do not empower...
