گسترش بازده و بی ثباتی در صنعت بانکداری اروپا در طول بحران مالی جهانی: پرواز برای کیفیت ادراک شده و یا سرایت؟

This paper empirically investigates return, volatility and leverage spillover effects between banking industrial stock markets of the major economies (ME) (Germany, UK and US) and the smaller stressed European Union countries (SE), (Italy, Ireland, Greece, Spain and Portugal) from 2002 to 2014 which includes the global financial crisis period (2007–2014). Thus the paper investigates the influence of the global crisis on the spillover between the banking industrial stock markets of Europe and the US. We apply a multivariate GARCH–GJR framework to investigate the effects of the financial crisis with respect to spillover. Our results indicate an increase in both means and volatility spillover between the major economies and the stressed EU economies from the pre-crisis to the crisis period. During the pre-crisis period there is ample evidence of spillover from Germany, UK and the US to the smaller EU economies. Little evidence of a significant spillover from the smaller economies to the major economies is found during this period. We find that return and volatility transmission mechanisms between the major economies and the smaller EU countries are asymmetric during the crisis period. During the crisis, the level and amount of spillover from the major economies increase. But now there is also clear evidence of spillover from smaller EU economies to the major economies, this is especially true for Germany and the UK. Evidence of spillover effects suggests the existence of exploitable trading strategies and has important implications to investors in the areas of option pricing, portfolio optimization and risk management.
