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.
