The intellectual challenges facing central bankers are reflected in this monograph. The author worked as an economist in the Monetary and Economic Department of the Bank for International Settlements (BIS), but also as an international mediator, in the Secretariat of the G10 Ministers and Governors and in central bank governance. This book thus reveals, next to monetary policy and financial crisis, less well known topics such as insolvency, collective action clauses, international mediation and management of central banks.
