U.S. banks have increasingly diversified into activities traditionally considered as non-core for the banking sector. This paper investigates whether diversification influences banks' investment (credit) policy and profitability. Diversified banks appear to benefit from “coinsurance,” supply...

If regulation fails to differentiate between priced and idiosyncratic risk, it incentivizes investors to reach for yield. Studying securitization exposures on the balance sheets of German banks, I show evidence consistent with this prediction. Banks with tight regulatory constraints (low capital...

We develop a methodology to measure the capital shortfall of commercial banks in a market downturn, which we call stressed expected loss (SEL). We simulate a market downturn as a negative shock on interest rate and credit market risk factors that reflect the banks' market-sensitive assets. We...

We study bailouts of banks that suffer from debt overhang problems and have private information about the quality of their assets-in-place and new investment opportunities. Menus of bailout plans are used as a screening device. Constrained-optimality involves over capitalization and nonlinear...

In this paper we gauge the degree of interconnectedness and quantify the linkages between global and other systemically important institutions, and the global financial system. We document that the two groups and the financial system become more interconnected during the global financial crisis...

This paper models the strategic interaction between a rating agency, a banking sector and a bank regulator who lacks information about bank asset risk. The regulator can either (1) make bank capital requirements contingent on credit ratings; or (2) set rating independent capital requirements....

We develop a dynamic model of banking to assess the effects of liquidity and leverage requirements on banks' insolvency risk. In this model, banks face taxation, flotation costs of securities, and default costs and maximize shareholder value by making their financing, liquid asset holdings, and...

Although policy uncertainty has drawn regulators' attention in the aftermath of the global financial crisis, little is known on how to alleviate its adverse effects. In this paper, we examine the role of political connections in mitigating the detrimental impact of policy uncertainty on banks....

How do banks respond to changes in capital requirements as a result of the stress tests? Does the disclosure of stress test results matter? To answer these questions, we study the impact of European stress tests on banks' lending, their corresponding risk-taking, the ensuing effect on their...

The search for a market design that ensures stable bank funding is at the top of regulators' policy agenda. This paper empirically shows that the central counterparty (CCP)-based euro interbank repo market features this stability. Using a unique and comprehensive data set, we show that the...
