The economic impact of an institutional transplant depends on the underlying cultural environment of the receiving country. This paper provides the first evidence that the positive effect of importing good institutions cancels out when the receiving territories are characterized by cultural...

We study the role of morality in debt repayment, using an experiment with the credit card customers of a large Islamic bank in Indonesia. In our main treatment, clients receive a text message stating that “non-repayment of debts by someone who is able to repay is an injustice." This moral...

The study measures scientists’ polarization on social media and its impact on public perceptions of their credibility. Analyzing 98,000 scientists on Twitter from 2016 to 2022 reveals significant divergence in expressed political opinions. An experiment assesses the impact of online political...

We investigate the relationship between religion and trust. Using a questionnaire, we measure: i) general religiosity, and; ii) the extent of religious beliefs, experience, and ritual. These are then analyzed with behaviour in a trust game (Berg et al., Games and Economic Behaviour, 1995), which...

Violent conflict is sometimes believed to provoke discrimination, but sometimes also seen to reduce pro-sociality in general. While discrimination may reinforce conflict, a lack of pro-sociality hinders peace reconciliation, social capital formation and development. We test which of these...

Sacrifices to deities occur in nearly all known religions. In this paper, we report on our attempts to elicit this type of religious behaviour towards "Theoi" in the laboratory. The theory we test is that, when faced with uncertainty, individuals attempt to engage in a reciprocal contract with...

Madrassas (Islamic religious seminaries) have been alleged to be responsible for fostering Islamic extremism and violence, and for indoctrinating their students in narrow worldviews. However, we know very little about the behavior of Madrassa students, and how other groups in their communities...

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...

We examine the effect of adherence to behavioral codes, as measured by the degree of religiosity, on the level of honesty by conducting under-the-cup die experiments. The findings suggest that behavioral codes, which prohibit lying, offset the monetary incentive to lie. The highest level of...
