It is associated with Geneva’s Graduate Institute of International and Development Studies. Its aim is to foster exchanges of views between the financial sector, central banks and academics on issues of common interest. It is financed through grants from banks, financial institutions and central banks. The Center sponsors international conferences, public lectures, original research and publications. In association with CEPR, the Center has published the Geneva Reports on the World Economy since 1999. These reports attract considerable interest among practitioners, policymakers and scholars. ICMB is non-partisan and does not take any view on policy. Its publications, including the present report, reflect the opinions of the authors, not of ICMB or any of its sponsoring institutions. The President of the Foundation Board is Jaime Caruana and the Director is Ugo Panizza. CENTRE FOR ECONOMIC POLICY RESEARCH (CEPR) The Centre for Economic Policy Research (CEPR) is a network of over 1,300 research economists based mostly in European universities. The Centre’s goal is twofold: to promote world-class research, and to get the policy-relevant results into the hands of key decision-makers. CEPR’s guiding principle is ‘Research excellence with policy relevance’. A registered charity since it was founded in 1983, CEPR is independent of all public and private interest groups. It takes no institutional stand on economic policy matters and its core funding comes from its Institutional Members and sales of publications. Because it draws on such a large network of researchers, its output reflects a broad spectrum of individual viewpoints as well as perspectives drawn from civil society. CEPR research may include views on policy, but the Trustees of the Centre do not give prior review to its publications. The opinions expressed in this report are those of the authors and not those of CEPR.

We VIII thank Rodrigo Hernán Pazos for superb research assistance, especially on Chapters 2 and 3. Special thanks are due to William Brainard, who managed to convey to us the spirit and the depth of the debate on the policy mix led by Okun and Tobin. Without implication in the remaining errors and omissions, extensive comments from our discussants, Katrin Assenmacher, Marco Buti, Benoît Coeuré, Bill English, and Ricardo Reis, as well as from Stefan Gerlach, Ugo Panizza, Angel Ubide, and conference participants, led to considerable improvements in the report.
