I develop a model of contagion that stems from endogenous risk-sharing when financial firms differ in distress levels. Firms face costly liquidation and strategically trade assets, thereby forming links. A link with a distressed firm can be socially costly as it raises system-wide liquidation...

I examine the relation between Federal Reserve emergency actions and aggregate U.S. systemic risk during the Global Financial Crisis (GFC) and the COVID-19 crisis. I divide these actions in to three categories: lender of last resort (LLR), liquidity provision, and open market operations (OMO)....

We model the systemic risk associated with the so-called balance-sheet amplification mechanism in a system of banks with interlocked balance sheets and with positions in real-economy-related assets. Our modeling framework integrates a stochastic price dynamics with an active balance-sheet...

We study banks’ year-end window dressing in the European Union to assess how it affects the identification of global systemically important banks (G-SIBs) and the associated capital surcharges. We find that G-SIBs compress their balance sheet at year-end to an extent that they can reduce their...

During the 2007-2009 financial crisis certain events in the American financial system affected financial markets around the globe. Moreover, since the onset of the euro zone sovereign debt crisis, the systemic risk in Europe also appeared to affect the banking sector risk in other regions. While...

This paper provides evidence on how the new international regulation on Global Systemically Important Banks (G-SIBs) impacts the market value of large banks. We analyze the stock price reactions for the 300 largest banks from 52 countries across 12 relevant regulatory announcement and...

We study the impact of changes in regulations and policy interventions on systemic risk among European sovereigns measured as volatility spillovers in respective credit risk markets. Our unique intraday CDS dataset allows for precise measurement of the effectiveness of these events in a network...

This paper examines whether banks' liquidity and maturity mismatch decisions are affected by the choices of competitors and the impact of these coordinated funding liquidity policies on financial stability. Using a novel identification strategy where interactions are structured through decision...
