Amid the growing financial vulnerabilities posed by climate change, we investigate macroprudential capital buffers to mitigate systemic risks and increase the resilience of the banking sector. Leveraging granular data and state-of-the-art stress testing methods, we quantify potential bank losses...

Regulatory stress-testing is an important tool for ensuring banking system health in many countries around the world. Current methodologies ensure banks are well capitalized against the scenarios in the test, but it is unclear how resilient banks will be to other plausible scenarios. This paper...

In this study we disentangle two dimensions of banks' systemic risk: the level of bank tail risk and the linkage between a bank's tail risk and severe shocks in the financial system. We employ a measure of the systemic risk of financial institutions that can be decomposed into two subcomponents...

This paper studies the problem of optimally allocating a cash injection into a financial system in distress. Given a one-period borrower-lender network in which all debts are due at the same time and have the same seniority, we address the problem of allocating a fixed amount of cash among the...

Conditional value at risk (CoVaR) and marginal expected shortfall (MES) have been proposed as measures of systemic risk. Some argue these statistics should be used to impose a “systemic risk tax” on financial institutions. These recommendations are premature because CoVaR and MES are ad hoc...

This paper focuses on the impact of financial market infrastructures (FMIs) and of their regulation on the post-crisis transformation of securities and derivatives markets. It examines, in particular, the role that trading and post-trading FMIs, and their new regulatory regime, are playing in...

This article analyzes the manifold situations in which the efficient-market hypothesis (EMH) has influenced—or has failed to influence—federal securities regulation and state corporate law, and the prospective roles for the EMH in these contexts. In federal securities regulation, the EMH has...

This is a chapter for a forthcoming volume Oxford Handbook of Financial Regulation (Oxford University Press 2014) (eds. Eilís Ferran, Niamh Moloney, and Jennifer Payne). It provides an overview of EU financial regulation from the first banking directive up until its most recent developments in...

Based on a review of international and regional responses to the global financial and economic crisis and its implications for finance in Asia, Douglas Arner and Lotte Schou-Zibell draw lessons for Asian financial systems with regard to the scope of regulation; financial standards; supervision,...

The European single market supported the creation of multinational banking groups. However, the European banking directives and the single license system were built along the model of the stand-alone bank and cannot keep pace with recent market developments. The national character of prudential...
