The concentration of risk within financial system is considered to be a source of systemic instability. We propose a theory to explain the structure of the financial system and show how it alters the risk taking incentives of financial institutions. We build a model of portfolio choice and...

We evaluate the institutional frameworks developed to implement time-varying macroprudential policies in 58 countries. We focus on new financial stability committees (FSCs) that have grown dramatically in number since the global financial crisis, and their interaction with central banks, and...

This paper examines the incentives of national regulators to coordinate regulatory policies in the presence of systemic risk in global financial markets. In a two-country and three-period model, correlated asset fire sales by banks generate systemic risk across national financial markets....

The Basel Committee promulgates bank regulatory standards that many major economies enact to a significant extent. One element of the Basel III capital standards is a system of capital surcharges for global systemically important banks (G-SIBs). If the purpose of the surcharges is to ensure the...

We evaluate how a country's governance structure for macroprudential policy affects its implementation of Basel III macroprudential capital buffers. We find that the probabilities of using the countercyclical capital buffer (CCyB) are higher in countries that have financial stability committees...

Stress testing has become an increasingly important mechanism to support a variety of financial stability objectives. Stress tests can be used to test the individual resilience of a single entity or to assess the system-wide vulnerabilities of a network. This article examines the role of...

This paper updates the standard workhorse model of banks' reserve management to include frictions inherent to money markets. We apply the model to study monetary policy implementation through an operating regime involving voluntary reserve targets (VRT). When reserves are abundant, as is the...

We examine whether financial stress at larger banks has a different impact on the real economy than financial stress at smaller banks. Our empirical results show that stress experienced by banks in the top 1 percent of the size distribution leads to a statistically significant and negative...

This paper examines whether banks strategically incorporate their competitors' liquidity mismatch policies when determining their own and how these collective decisions impact financial sector stability. Using a novel identification strategy exploiting the presence of partially overlapping peer...

We examine the implications of less powerful forward guidance for optimal policy using a sticky-price model with an effective lower bound (ELB) on nominal interest rates as well as a discounted Euler equation and Phillips curve. When the private-sector agents discount future economic conditions...
