The CIGI Essays on International Finance aim to promote and disseminate new scholarly and policy views about international monetary and financial issues from internationally recognized academics and experts. The essays are intended to foster multidisciplinary approaches by focussing on the interactions between international finance, global economic governance and public policy. The inaugural volume in the series, written by Harold James, discusses the purposes and functions of central banks, how they have changed dramatically over the years and the importance of central bank cooperation in dealing with international crises.
