Too often, people overlook economic growth when thinking about how to tackle the world’s most pressing problems, such as poverty, illiteracy, income inequality, unemployment, and pollution. At the same time, our understanding of eco- nomic growth is less defi nitive than commonly thought—even though advice is often given to developing countries with great confi dence. Conse- quently, the Commission’s mandate is to “take stock of the state of theo- retical and empirical knowledge on economic growth with a view to drawing implications for policy for the current and next generation of policy makers.” To help assess the state of knowledge, the Commission invited lead- ing academics and policy makers from around the world to a series of 12 workshops, held in 2007 and 2008 in Washington, D.C., New York, and New Haven, and commissioned a series of thematic papers. These papers reviewed areas such as monetary and fi scal policy, climate change, inequal- ity, growth, and urbanization—the subject of this volume. In addition, 25 case studies were commissioned to explore the dynamics of growth in spe- cifi c countries. Each presentation benefi ted from comments by members of the Commission and other workshop participants from the worlds of policy, theory, and practice. The workshops turned out to be intense and lively affairs, lasting up to three days. It became clear that experts do not always agree, even on issues that are central to growth. The Commission had no wish to disguise or gloss over these uncertainties and differences. It did not want to present a Preface ix false confi dence in its conclusions, beyond that justifi ed by the evidence. Researchers do not always know the correct “model” that would explain the world they observe; and even if they know the factors that matter, they cannot always measure them convincingly. While researchers will continue to improve our knowledge of the world, policy makers cannot wait for scholars to satisfy all of their doubts or resolve their differences. Decisions must be made with only partial knowl- edge of the world. One consequence is that most policy decisions, however well-informed, take on the character of experiments, which yield useful information about the way the world works, even if they do not always turn out the way policy makers hoped.
