Systemically important banks are subject to at least two departures from the neutrality of debt versus equity financing: the tax deductibility of interest payments and implicit funding subsidies. This paper fills a gap in the literature by comparing their mechanism and interaction within a...

I develop a model where the sovereign debt capacity depends on the capitalization of domestic banks. Low-capital banks optimally tilt their government bond portfolio toward domestic securities, linking their destiny to that of the sovereign. If the sovereign risk is sufficiently high,...

I identify new patterns in countries' economic performance over the 2007-2014 period based on proximity through distance, trade, and finance to the US subprime mortgage and Eurozone debt crisis areas. To understand the causes of the cross-country variation, I develop an open economy model with...

At the 25th anniversary of the Maastricht Treaty, this paper reviews the merits of introducing a safe sovereign asset for the eurozone. The triple euro area crisis showed the costly consequences of ignoring the "safety trilemma". Keeping a national safe sovereign asset (the German bund) as the...

I propose a dynamic general equilibrium model in which strategic interactions between banks and depositors may lead to endogenous bank fragility and slow recovery from crises. When banks' investment decisions are not contractible, depositors form expectations about bank risk-taking and demand a...

We study determinants of sovereign portfolios of Spanish banks over a long time-span, starting in 2008. Our findings challenge the view that banks engaged in moral hazard strategies to exploit the regulatory treatment of sovereign exposures. In particular, we show that being a weakly capitalized...

This paper investigates the effect of structural characteristics on debt limits of middle income countries. Two equations relate the probability of default to the interest rate. First, the probability of default is estimated with a logit model. Second, the assumption of non-arbitrage opportunity...
