We felt that the benefi ts of growth were not fully appreciated, but we also recognized that the causes of growth were not fully understood. Growth is often overlooked and underrated as an instrument for tackling the world’s most pressing prob- lems, such as poverty, illiteracy, income inequality, unemployment, and pollution. At the same time, our grasp of the sources of growth in develop- ing countries is less defi nitive than commonly thought—even though advice is sometimes given to policy makers in these countries with great confi - dence, perhaps greater than the state of our knowledge would justify. Con- sequently, the Commission’s mandate is to “take stock of the state of theoretical and empirical knowledge on economic growth with a view to drawing implications for policy for the current and next generation of policy makers.” The 21 commissioners included 19 experienced leaders from govern- ment and business, mostly from the developing world, and two Nobel Prize–winning economists. To help assess the state of knowledge, the Commission invited leading academics and policy makers from around the world to a series of 12 workshops, held in 2006, 2007, and 2008 in Washington, D.C., New York, and New Haven. A series of thematic papers, as well as 25 country case studies exploring the dynamics of growth in specifi c countries, was commissioned. The Commission also met several times in Washington, Singapore, New York, and Suzhou. The workshop papers reviewed issues such as monetary and fi scal policy, cli- mate change, inequality, growth, urbanization, education, and health— the subject of this volume. Each presentation benefi ted from comments by Preface ix members of the Commission and other workshop participants from the worlds of policy, theory, and practice.
