Formation of Cooperation Structures in Economic and Social Situations

在这个项目中，PI建立了博弈论模型来研究网络的形成和稳定性，并将其应用于合并政策和互联网。这项研究的灵感来自于正在建立的理论的可能应用，而不是以理论本身为出发点。从研究经济和社会情况下的网络结构中获得的见解被用来确定网络的具体类型和网络在其中发挥重要作用的特定情况。通过纳入这些情况的机构细节而强加的额外结构可能会产生易于处理的模式和与政策有关的结果。现有的合作结构(形成)模型被扩展到包括网络中链路的成本，并研究代理群体之间存在外部性的情况。随着近年来互联网的快速发展和经济的全球化，网络显然对我们的日常生活产生了重大影响。最近的研究从几个不同的角度解决了合作结构的建模问题。然而，有趣的问题仍然存在，不能用目前已知的模型和技术来回答。这些问题包括古诺公司的合并和互联网的扩展，以及与此扩展相关的问题。

In this project, the PI formulates game theoretic models to study the formation and stability of networks, with applications to merger policy and the internet. The research is inspired by possible applications of the theory that is being build, rather than taking the theory itself as a point of departure. Insights gained from the study of network structures in economic and social situations, are used to identify specific types of networks and specific circumstances in which networks play an important role. Additional structure imposed by incorporating the institutional details of these situations are likely to produce tractable models and policy-relevant results. The existing models of (the formation of) cooperation structures are extended to encompass costs on links in networks and to study situations in which there are externalities between groups of agents. With the rapid evolution of the internet recent years and globalization of the economy, it is apparent that networks have a major influence on our daily lives. Recent research tackles the problem of modeling cooperation structures from several different perspectives. However, interesting problems remain that cannot be answered using the models and the techniques that are currently known. These problems include mergers by Cournot firms and the extension of the internet and the problems associated with this extension.
