报告摘要:Networks are at the forefront of research in economics and operations research as powerful tools to model social and economic interactions. In network formation theory, one of the most important stability concepts for networks is pairwise stability. We develop a path-following algorithm that is effective in computing pairwise stable networks for a generic network formation problem. To do so, we reformulate the concept of pairwise stability as a Nash equilibrium of a non-cooperative game played by the links in the network and adapt the linear tracing procedure for non-cooperative games to the network formation problem. As a by-product of our main result, we obtain that the number of pairwise stable networks is generically odd. We apply the algorithm to a model of social communication.
