In my view, the essays collected in this volume provide a rich set of landmarks in a terrain that a great many regulatory practitioners—financial and otherwise—are already exploring. This volume helps clarify the aspirations of modern regulatory professionals as they confront increasingly complex and rapidly evolving risks. It highlights the strategic and organizational challenges a supervisory agency faces when it shifts its overarching framework from compliance-management to risk-control. And it provides an illuminating collection of innovative ideas, many of which could readily and usefully be translated into other regulatory settings. I heartily commend it to you. Malcolm K.
