Spillover effects of credit default risk in the euro area and the effects on the Euro: A GVAR approach
本文用全球向量自回归模型分析欧元区九国及日英美数据，发现一般风险溢出效应强于救助风险，欧元在一般风险冲击下对日元和美元显著贬值，而英镑不受影响。
Abstract During the 2008 financial crisis, increasing risk and spillovers became a main concern for policy makers and banks. In addition, changes in sovereign and bank risk are believed to have had strong effects on world‐wide exchange rates. This paper aims to analyse these dynamics empirically. We estimate a Global VAR (GVAR) model for nine EMU countries plus Japan, the United Kingdom, and the United States and identify structural risk shocks using sign restrictions. Our results indicate that spillover effects of general risk are much stronger than those of bailouts. Furthermore, we demonstrate that the Euro depreciates significantly against the Yen and U.S. dollar following general risk shocks in the euro area and only to a small extent following bailout shocks. The Pound Sterling is not affected by any of these shocks. The Euro variability is, from the EMU perspective, mainly driven by shocks stemming from large countries (e.g., Germany, France, and Italy). However, shocks from third countries also play an important role.
