Although economic growth has historically been an engine of prosperity in the United States, recent trends have generated uncertainty regarding the prospects for sustaining such growth. Economists disagree about the relative importance of many factors affecting future growth, including rapid technological advances, immigration, the growth of the financial sector, problems with the educational system, increasing income inequality, an aging population, and large fiscal imbalances that have not been addressed by the political system. This collection of chapters, authored by many of today's leading economists, addresses the prospects for economic growth in the United States over the next few decades. During a time of great economic uncertainty, this book engages with both sides in the debate over economic growth, focusing on policy options that increase the prospects for vigorous economic growth in the future.
