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
