Risk shocks and divergence between the Euro area and the US

Why have the Euro area and the US diverged since 2011 while they were highly synchronized during the recession of 2008-2009? To explain this divergence, we provide a structural interpretation of these episodes through the estimation of a business cycle model with financial frictions for both economies. Our results show that risk shocks, measured as the volatility of idiosyncratic uncertainty in the financial sector, have played a crucial role in the divergence with the absence of risk reversal in the Euro area. Risk shocks have stimulated US credit and investment growth since the trough of 2009 whereas they have been at the origin of the double-dip recession in the Euro area.
