On the topology of the world exchange arrangements web
Li, Xiang; Jin, Yu Ying; Chen, Guanrong - In: Physica A: Statistical Mechanics and its Applications 343 (2004) C, pp. 573-582
Exchange arrangements among different countries over the world are foundations of the world economy, which generally stand behind the daily economic evolution. As the first study of the world exchange arrangements web (WEAW), we built a bipartite network with countries as one type of nodes and...
