We develop a macroeconomic agent-based model to study how financial instability can emerge from the co-evolution of interbank and credit markets and the policy responses to mitigate its impact on the real economy. The model is populated by heterogenous firms, consumers, and banks that locally...

This paper presents a new theory that explains why it is beneficial for banks to be highly interconnected and to engage in herding behavior. It shows that these two important causes of systemic risk are interdependent and thus cannot be considered in isolation. The reason is that banks have an...

We examine insurance against loan default when lenders can screen in primary markets at a heterogeneous cost and learn loan quality over time. In equilibrium, low-cost lenders screen loans but some high-cost lenders insure them. Insured loans are risk-free and liquid in a secondary market, while...

We take issue with claims that the funding mix of banks, which makes them fragile and crisisprone, is efficient because it reflects special liquidity benefits of bank debt. Even aside from neglecting the systemic damage to the economy that banks' distress and default cause, such claims are...

How does monetary policy impact upon macroprudential regulation? This paper models monetary policy's transmission to bank risk taking, and its interaction with a regulator's optimization problem. The regulator uses its macroprudential tool, a leverage ratio, to maintain financial stability,...

We empirically investigate why wholesale funding is fragile by providing the first study of how individual banks borrow and lend in the euro unsecured and secured interbank market. Consistent with theories in which lenders enforce market discipline by monitoring counterparty credit risk and...

We show that banks' risk exposure in one asset category affects how they report regulatory risk weights for another asset category. Specifically, banks report lower credit risk weights for their loan portfolio when they face higher risk exposure in their trading book. This relationship is...

We empirically analyze to which extent popular global systemic risk measures (SRMs) yield comparable results with respect to the systemic importance of a financial institution and, in particular, from which determinants the degree of consistency of the classification by the various SRMs depends....

This paper analyses the impact of different treatments of government bonds in bank liquidity regulation on financial stability. Using a theoretical model, we show that a sudden increase in sovereign default risk may lead to liquidity issues in the banking sector, implying the insolvency of a...

A bank's decision on loan supply and capital structure determines its immediate bankruptcy risk as well as the future availability of internal funds. These internal funds in turn determine a bank's future costs of external finance and future vulnerability to bankruptcy risks. We study these...
