In this project the Principal investigators will investigate the social network effects on coordination and cooperation. While most existing work provides insights on the influence of group size on coordination and cooperation, we examine the role of group structure. First we will analyze a laboratory experiment on a coordination game in which each player engages with an exogenously connected ?local? subset of the player population, the pattern of connections defining a social network. The main research question we will address is How does the social network structure affect coordination behavior? We identify sources of influence on coordination from both global network (the density of overall network) and local network (the connectedness of individuals). In our experiment, both full-coordination and no-coordination are pooling equilibria in all laboratory networks, while in one case there is also a separating equilibrium, where players coordinate only if they have an enough number of local social links. In a pilot study we observe nearly complete coordination in denser networks but less so in sparser networks. Via a laboratory public goods game, we will study the impact of social network architecture on cooperation. Our research foci are the fairness and social welfare in equilibria as affected by network configurations. To analyze the data collected from experiments, we shall apply various statistical techniques including nonparametric methods and logit regressions (adjusted to individual heterogeneity). In terms of broader impacts, this research examines how the social network, which determines ?who plays the game with whom?, affects the outcome of coordination and cooperation. Our results might guide Internet service and platform providers in developing effective online social networks to promote service and products, and assist policy makers in seeking for efficient network layouts to facilitate the spread of goods or activities that are socially beneficial. The products of the proposed study will be made publicly available for research and educational uses at no cost.

在这个项目中，主要研究人员将研究社会网络对协调与合作的影响。虽然大多数现有的工作提供了深入了解组的规模对协调与合作的影响，我们研究组结构的作用。首先，我们将分析一个实验室实验的协调游戏中，每个球员从事与外部连接？本地的？玩家群体的子集，定义社交网络的连接模式。我们要解决的主要研究问题是社会网络结构如何影响协调行为？我们从全局网络（整体网络的密度）和局部网络（个人的连通性）两个方面确定了影响协调的来源。在我们的实验中，完全协调和不协调都是所有实验室网络中的汇集均衡，而在一种情况下，也有一个分离均衡，只有当玩家有足够数量的本地社会联系时，他们才会协调。在一项试点研究中，我们观察到在密集的网络中几乎完全协调，但在稀疏的网络中则较少。通过一个实验室公共物品博弈，我们将研究社会网络结构对合作的影响。我们的研究重点是网络结构对均衡中的公平和社会福利的影响。为了分析从实验中收集的数据，我们将应用各种统计技术，包括非参数方法和logit回归（调整个体异质性）。在更广泛的影响方面，这项研究探讨了如何社会网络，这决定了？谁和谁玩游戏？影响协调与合作的结果。研究结果可为互联网服务和平台提供商开发有效的在线社交网络以推广服务和产品提供指导，并有助于政策制定者寻求有效的网络布局，以促进对社会有益的商品或活动的传播。拟议研究的成果将免费公开供研究和教育使用。
