Globalization makes cross-national encounters increasingly common. Hesitant cooperation across national, ethnic, and cultural boundaries, however, undercuts the microlevel stabilizers of global integration and, most importantly, the willingness to share with and place trust in members of other social groups. In a 109-country online experiment, we convey information on interaction partners' nationalities to indicate membership in a broader in- or out-group, cultural distance, and perceived material neediness—or status differences more generally—to 1,674 participants in incentivized games of generosity (dictator game) and trust (trust game). We find consistent evidence for in-group favoritism and—against this benchmark—demonstrate that individuals across the globe share more with but place less trust in interaction partners from poor countries and that cultural distance moderates this status effect.

全球化使跨国遭遇越来越普遍。但是，跨越国家，种族和文化边界的犹豫合作削弱了全球一体化的微观层面的稳定器，最重要的是削弱了与其他社会群体的成员分享和信任的意愿。在109个国家/地区的在线实验中，我们传达了与合作伙伴的国籍有关的信息，以向1,674名参加过激励游戏的参与者表明，他们属于更广泛的组内或组外成员，文化距离和感知的物质需求（或更普遍的状态差异）。慷慨（独裁者博弈）和信任（信任博弈）。
