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 study the prices that individual banks pay for liquidity (captured by borrowing rates in repos with the central bank and benchmarked by the overnight index swap) as a function of market conditions and bank characteristics. These prices depend in particular on the distribution of liquidity...

This paper shows how the combined endogenous reaction of banks and investment funds to an exogenous shock can amplify or dampen losses to the financial system compared to results from single-sector stress testing models. We build a new model of contagion propagation using a very large and...

Europe's financial structure has become strongly bank-based – far more so than in other economies. We document that an increase in the size of the banking system relative to equity and private bond markets is associated with more systemic risk and lower economic growth, particularly during...

How do capital and liquidity buffers affect the evolution of bank loans in periods of financial and economic distress? To answer this question we study the responses of 219 individual banks to aggregate demand, standard and unconventional monetary policy shocks in the euro area between 2007 and...

Both in the United States and in the Euro area, bank supervision is the joint responsibility of local and central/federal supervisors. I study how such a system can optimally balance the lower inspection costs of local supervisors with the ability of the central level to internalize cross-border...

Outlier detection in high-dimensional datasets poses new challenges that have not been investigated in the literature. In this paper, we present an integrated methodology for the identification of outliers which is suitable for datasets with higher number of variables than observations. Our...

Using a difference-in-differences approach and relying on confidential supervisory data and an unique proprietary data set available at the European Central Bank related to the 2016 EU-wide stress test, this paper presents novel empirical evidence that supervisory scrutiny associated to stress...

Using a unique dataset of the Euro area and the U.S. bank lending standards, we find that low (monetary policy) short-term interest rates soften standards, for household and corporate loans. This softening – especially for mortgages – is amplified by securitization activity, weak supervision...

This paper examines common regulation as cause of interbank contagion. Studies based on the correlation of bank assets and the extent of interbank lending may underestimate the likelihood of contagion because they do not incorporate the fact that banks have a common regulator. In our model, the...
