We experimentally show that current models of reciprocity are in- complete in a systematic way using a new variant of the ultimatum game that provides second-movers with a marginal-cost-free punish- ment option. For a substantial proportion of the population, the de- gree of rst-mover unkindness...

An unprecedented number of refugees from Syria has sought refuge in both the Middle East and Europe since the beginning of the civil war in Syria in 2011. We analyze the level of altruism and risk-seeking among Syrian civil war victims in Jordan. We find systematic variations in their revealed...

We analyze possible links between both trust and trustworthiness among Syrian refugees in Germany in relation to the refugees' involvement in two different forms of social networking (forming bonding ties with other refugees vs. forming bridging ties between refugees and Germans). We implement...

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...

The price mecanism is the primary means of information transfer in decentralized economic systems. High prices indicate high demand, whereas low prices indicate low demand. Thus prices are the signals for accelerating or slowing production. However, using sequential, multi-unit auctions, we show...
