International financial linkages, particularly through global bank flows, generate important questions about the consequences for economic and financial stability, including the ability of countries to conduct autonomous monetary policy. I address the monetary autonomy issue in the context of...

This paper proposes an alternative framework to set banks’ operational risk capital, which allows for forward-looking assessments and limits gaming opportunities by relying on an incentive-compatible mechanism. This approach would improve upon the vulnerability to gaming of the AMA and...

Basel's new standardized approach (SA) for operational risk capital may allow for regulatory arbitrage through the use of insurance. Under the SA, banks will have incentive to insure recurring losses, which can meaningfully reduce capital requirements even as it does not meaningfully decrease...

This paper proposes an alternative framework to set banks' operational risk capital, which allows for forward-looking assessments and limits gaming opportunities by relying on an incentive-compatible mechanism. This approach would improve upon the vulnerability to gaming of the AMA and the lack...

Seven desirable properties for a capital framework are proposed, and the Advanced Measurement Approach (AMA) and the new standardized approach (NSA) for operational risk capital are evaluated relative to them. The AMA is vulnerable to gaming, complex, and lacks comparability. The NSA lacks risk...

Operational risk is a substantial source of risk for US banks. Improving the performance of operational risk models' allows banks' management to make better risk decisions by better matching economic capital and risk appetite, and allows regulators to better understand the risk of banks. We show...

The Advanced Measurement Approach (AMA) to operational risk capital is vulnerable to gaming, complex, and lacks comparability. The Standardized Measurement Approach (SMA) to operational risk capital lacks risk sensitivity and is unlikely to be appropriately conservative for US banks. An...

Banks have progressively evolved from being standalone institutions to being subsidiaries of increasingly complex financial conglomerates. We conjecture and provide evidence that the organizational complexity of the family of a bank is a fundamental driver of the business model of the bank...

Operational risk is a substantial source of risk for US banks. Improving the performance of operational risk models allows banks’ management to make more informed risk decisions by better matching economic capital and risk appetite, and allows regulators to enhance their understanding of...
