Research Handbook on International Banking and Governance

Edited by James R. Barth, Chen Lin and Clas Wihlborg

The contributors – top international scholars from finance, law and business – explore the role of governance, both internal and external, in explaining risk-taking and other aspects of the behavior of financial institutions. Additionally, they discuss market and policy features affecting objectives and quality of governance. The chapters provide in-depth analysis of factors such as: ownership, efficiency and stability; market discipline; compensation and performance; social responsibility; and governance in non-bank financial institutions. Only through this kind of rigorous examination can one hope to implement the financial reforms necessary and sufficient to reduce the likelihood and severity of future crises.

Because financial instruments such as mortgages, bonds and derivatives operate in several markets at the same time, they are subject not only to the internal dynamics inherent in those particular markets, but to interactive risks as well, emanating from the wider financial system. In fact, trading those financial instruments might have originated the interactive risks – they reflect correlations across activities and markets when losses in one area affect losses in another. The solutions are much harder to find than when discrete sectors or markets are affected. The operative rule for policymakers who resort to social science is that one must know the cause of...
