It is now abundantly clear that social norms channel behavior and impact economic development. This insight leads to the question: How do social norms evolve? This survey examines research that relies on geography to explain the development of social norms, and suggests that religion and family...

Constitutional Economics - the analysis of constitutions drawing on the economic approach - has made important progress over the last two decades. The factors determining whether a constitution is complied with, however, have received only little attention. This is surprising, as a huge gap...

The rule of law, a fundamental value of the European Union (EU), has come under stress in a number of its member states. The EU's response to these stresses has been criticized as politicized, slow, and unassertive. This research note develops a proposal to improve the current procedure.

We compare their behavior with Jordanians, Germans, and Syrians who still live in Syria. The average number of lies is amazingly similar -...

Does the experience of civil war promote in-group bias among survivors? We try to answer this question by analyzing cooperation in a prisoner's dilemma game among Syrian refugees in two host countries, Germany and Jordan. We use a between-subjects analysis to test our in-group cooperation...
