成功地将新移民融入当地社区已成为决策者面临的一个关键问题，因为移民数量的增加给接收国带来了文化多样性和新技能，但也带来了社会紧张局势。我们开发了一个基于代理的网络模型来研究相互作用的“主人”和“客人”，并确定合作/一体化或不合作/隔离社会出现的条件。假设玩家通过改变网络链接的博弈论规则来寻求社会经济繁荣，并通过舆论动态来寻求文化接受。我们发现，对于客人和主人来说，在给定初始条件下，融合的主要预测因素是与文化调整相对于社会联系重塑相关的时间尺度。快速的文化调整导致合作和建立长期持续的主客关系。相反，快速的社会联系重塑会导致不可逆转的孤立飞地的形成，因为移民和当地人通过群体内的联系来优化他们的社会经济收益。我们讨论了移民人口规模以及通过政府激励措施或通过接纳具有高度理想技能的移民来增加主客互动的社会经济回报如何影响整体移民体验。
Successfully integrating newcomers into native communities has become a key issue for policy makers, as the growing number of migrants has brought cultural diversity, new skills, but also, societal tensions to receiving countries. We develop an agent-based network model to study interacting "hosts" and "guests" and to identify the conditions under which cooperative/integrated or uncooperative/segregated societies arise. Players are assumed to seek socioeconomic prosperity through game theoretic rules that shift network links, and cultural acceptance through opinion dynamics. We find that the main predictor of integration under given initial conditions is the timescale associated with cultural adjustment relative to social link remodeling, for both guests and hosts. Fast cultural adjustment results in cooperation and the establishment of host-guest connections that are sustained over long times. Conversely, fast social link remodeling leads to the irreversible formation of isolated enclaves, as migrants and natives optimize their socioeconomic gains through in-group connections. We discuss how migrant population sizes and increasing socioeconomic rewards for host-guest interactions, through governmental incentives or by admitting migrants with highly desirable skills, may affect the overall immigrant experience.
