Financial institutions are increasingly linked internationally. As a result, financial crisis and government intervention have stronger effects beyond borders. We provide a model of international contagion allowing for bank bailouts. While a social planner trades off tax distortions, liquidation...

We present a network model of the interbank market in which optimizing risk averse banks lend to each other and invest in non-liquid assets. Market clearing takes place through a tâtonnement process which yields the equilibrium price, while traded quantities are determined by means of a...

We analyze the link between banking sector quality and sovereign risk in the whole European Union over 1999–2014. We employ four different indicators of sovereign risk (including market- and opinion-based assessments), a rich set of theoretically and empirically motivated banking sector...

Since the beginning of 2010, the Euro Area faces a severe sovereign debt crisis, now generally known as the Euro Crisis. While the Euro Crisis has its origin in Greece, problems have now spread to several other European countries as well. Dynamic conditional correlation models (DCC) are...

We study the formation of networks in environments where agents derive benefits from other agents directly linked to them but suffer losses through contagion when any agent on a path connected to them is hit by a shock. We first consider networks with undirected links (e.g. epidemics,...

We develop a sovereign debt model with official and private creditors where default risk depends on both the level and the composition of liabilities. Higher exposure to official lenders improves incentives to repay but carries extra costs, such as reduced ex-post flexibility. The model implies...

Most theoretical central bank models use short horizons and focus on a single tradeoff. However, in reality central banks play complex, long horizon games and face more than one tradeoff. We account for these issues in a simple infinite horizon game with a novel tradeoff: higher rates deter...

We investigate the trade-off between the risk-sharing gains enjoyed by more interconnected firms and the costs resulting from an increased risk exposure. We find that when the shock distribution displays “fat” tails, extreme segmentation into small components is optimal, while minimal...

Interbank claims are a concern to regulators as they might facilitate the dissemination of defaults and generate spill-over effects. Building on a simple model, this paper introduces a measure of the spill-over effects that a bank generates when it defaults. The measure is based on an explicit...

We provide a first attempt to include off-balance sheet, implicit insurance to SIFIs into a consistent assessment of fiscal sustainability, for 27 countries of the European Union. We first calculate tax gaps à la Blanchard (1990) and Blanchard et al. (1990). We then introduce two alternative...
