Credit Default Swaps on Municipal Bonds: A Double-Edged Sword?
The municipal bond market has traditionally been viewed as a relatively safe market, where credit risk wasn\u27t a primary concern. The spate of fiscal crises that state and local governments have experienced in recent years, however, has changed this narrative
Better synchronizability predicted by a new coupling method
In this paper, inspired by the idea that the hub nodes of a highly
heterogeneous network are not only the bottlenecks, but also effective
controllers in the network synchronizing process, we bring forward an
asymmetrical coupling method where the coupling strength of each node depends
on its neighbors' degrees. Compared with the uniform coupled method and the
recently proposed Motter-Zhou-Kurth method, the synchronizability of scale-free
networks can be remarkably enhanced by using the present coupled method.Comment: 6 pages, 6 figures; to be published in EPJ
