In this paper we present a methodology of model-based calibration of additional capital needed in an interconnected financial system to minimize potential contagion losses. Building on ideas from combinatorial optimization tailored to controlling contagion in case of complete information about...

We present a two-country model with an enhanced banking sector featuring risky lending and cross-border interbank market frictions. We find that (i) the strength of the financial accelerator, when applied to banks operating under uncertainty in an interbank market, will critically depend on the...

The growth in TARGET balances after 2009 has given rise to intense academic and public debate. Our paper offers a systematic exposition of the necessary conditions for TARGET balances to emerge and provides a clear link to monetary policy. We show that large TARGET balances can only arise with...

We study the macroeconomic consequences of the money market tensions associated with the .nancial crisis in the euro area. In a structural VAR, we identify a liquidity shock rooted in the interbank market and use its impulse response functions to calibrate key parameters of a Smets and Wouters...

This paper investigates the effects of interbank rate uncertainty on lending rates to euro area firms. We introduce a novel measure of interbank rate uncertainty, computed as the cross-sectional dispersion in interbank market rates on overnight unsecured loans. Using proprietary bank-level data,...

We study how banks manage their liquidity among the various assets at their disposal. We exploit the introduction of the ECB's two-tier system which heterogeneously reduced the cost of additional reserves holdings. We find that the treated banks increase reserve holdings by borrowing on the...

Interbank money markets have been subject to substantial impairments in the recent decade, such as a decline in unsecured lending and substantial increases in haircuts on posted collateral. This paper seeks to understand the implications of these developments for the broader economy and monetary...

We study how monetary policy affects local market competition in a union of countries experiencing different economic conditions: the euro area. We find that when monetary conditions tighten (loosen), from the point of view of an individual economy, market concentration increases (declines)....
