Accelerating energy innovation could be an important part of an effective response to the threat of climate change. This book complements existing research on the subject with an exploration of the role that public and private policy have played in enabling—and sustaining—swift innovation in a variety of industries, from agriculture and the life sciences to information technology. Chapters highlight the factors that have determined the impact of past policies, and suggest that effectively managed federal funding, strategies to increase customer demand, and the enabling of aggressive competition from new firms are important ingredients for policies that affect innovative activity.

This is volume I of a four volume set, with papers developed as part of a large-scale project and associated conference series funded by the Gates Foundation. It is comprised of careful empirical reports on progress with economic, political, and social development in Africa over recent decades. Papers are grouped by a rough hierarchy of development. The first volume therefore deals with the essential issues that any country must resolve if there is to be any kind of sustained economic growth and shared benefits from development: is there social peace, does the government function in any kind of reasonable manner, and how does the private sector cope with government dysfunction? The broad theme of our project was that Africa has made much more progress with economic and social development than is widely supposed, and that there is a great deal of success – particularly since 1990 – from which lessons can be gleaned. The papers in this volume deal with ensuring peace after civil conflict, establishing a robust level of revenue for government, thinking about the implications of who holds political power, creating secure property rights, and understanding the nature of the informal economy. Papers also cover important policy innovations, both around road safety and economic development more broadly. We also include a paper that could become a model of how to measure changes in household and per capita income using available data from Africa, and a detailed case study that focuses on the impact of foreign aid on growth.

This is Volume II of a four set series that reports on progress with economic, political, and social development in Africa over recent decades. Volume I deals with social peace, the basic functioning (or not) of government, and how to measure economic development at the household level. Volume II is focused on human capital. This includes public health and various efforts to improve the empowerment–and thus the human development outcomes–for women and girls. We place these issues in a broad economic context, and also include some cutting-edge research on other dimensions of human capital in the African development context. As with the overall economic picture on the past two decades, there are signs of improvement along purely social dimensions of development in Africa. Volume I established that the institutional context for development in Africa remains difficult. But a key theme in Volume II is that no one should conclude that African specifics imply nothing works or that everything becomes corrupted into being completely ineffective. Our researchers have identified important issues, as well as interventions or policy innovations that appear to be gaining traction. The companion volumes III and IV deal with modernization and sustainable growth respectively. Countries covered in detail in this volume include Burkina Faso, Burundi, Ghana, Guinea-Bissau, Kenya, Malawi, Tanzania, and Zambia.

This is Volume III of a four volume set that reports on progress with economic, political, and social development in Africa over recent decades. Volume I deals with the essential issues of social stability and other prerequisites for growth. Volume II covers health, gender, and education, all of which are of first-order importance if people are to benefit from and contribute to economic development. Volume III focuses on specific issues of modernization and three key sectors or types of economic activity: finance, mobile phones, and exports. The papers in Volume III contain some firm-level analysis, studies of specific sectors, and cross-country econometrics. We did not attempt to build a comprehensive picture across all countries, but there is a great deal of information about what is going on in wide range of countries – the chapters in this volume contain more in-depth studies of Burundi, Kenya, Lesotho, Malawi, Nigeria, and Tanzania. Our main goal was to provide a catalyst for applied research on Africa, and this set of papers demonstrates how we set about achieving that objective. The authors include top researchers, among them people with a great deal of Africa experience and those for whom this was their first time digging into African realities.

This is Volume IV of a four volume set reporting on research on Africa funded by the Gates Foundation. Volume I is focused on conditions that make growth possible; Volume II deals with human development; and Volume III discusses ways in which modernization has come to sub-Saharan Africa, including banking, mobile phones, and dimensions of the export sector. Volume IV examines whether recent African growth rates will prove sustainable. This volume offers three different ways to address this general question. First, five of our research teams look at the details of African agriculture, ranging from its overall prospects to the specific institutional arrangements in two countries. As in our other volumes, the chapters here set a high standard in terms of putting together high quality data and analyzing it using appropriate statistical and econometric technique. Second, one team looked carefully at barriers to trade within West Africa – what keeps markets segmented and prevents trade from developing? Can these obstacles be overcome in the foreseeable future? Four teams look at particular country case studies to understand growth and development and also pay considerable attention to episodes of poor economic performance. Researchers participating in this project were encouraged to combine careful NBER-type empirical analysis with investigations of specific country experiences. In terms of in-depth country analysis, this volume includes material on Cape Verde, Ghana, Kenya, Mali, Mauritius, Mozambique, Niger, Nigeria, Sierra Leone, and Uganda.

The past three decades have been characterized by vast change and crises in global financial markets—and not in politically unstable countries but in the heart of the developed world, from the Great Recession in the United States to the banking crises in Japan and the Eurozone. As we try to make sense of what caused these crises and how we might reduce risk factors and prevent recurrence, the fields of finance and economics have also seen vast change, as scholars and researchers have advanced their thinking to better respond to the recent crises. A momentous collection of the best recent scholarship, After the Flood illustrates both the scope of the crises’ impact on our understanding of global financial markets and the innovative processes whereby scholars have adapted their research to gain a greater understanding of them. Among the contributors are José Scheinkman and Lars Peter Hansen, who bring up to date decades of collaborative research on the mechanisms that tie financial markets to the broader economy; Patrick Bolton, who argues that limiting bankers’ pay may be more effective than limiting the activities they can undertake; Edward Glaeser and Bruce Sacerdote who study the social dynamics of markets and E. Glen Weyl, who argues that economists themselves are influenced by the incentives their consulting opportunities create.

When firms and people are located near each other in cities and in industrial clusters, they benefit in various ways, including by reducing the costs of exchanging goods and ideas. One might assume that these benefits would become less important as transportation and communication costs fall. Paradoxically, however, cities have become increasingly important, and even within cities, industrial clusters remain vital. This book brings together chapters that examine the reasons why economic activity continues to cluster together despite the falling costs of moving goods and transmitting information. The studies cover a wide range of topics and approach the economics of agglomeration from different angles. Together they advance the understanding of agglomeration and its implications for a globalized world.

The population base in both the United States and Japan is growing older and, as those populations age, they provoke heretofore unexamined economic consequences. This comparative volume, the third in the joint series offered by the National Bureau of Economic Research and the Japan Center for Economic Research, explores those consequences, drawing specific attention to four key areas: incentives for early retirement; savings, wealth, and asset allocation over the life cycle; health care and health care reform; and population projections. Given the undeniable global importance of the Japanese and U.S. economies, these chapters shed light on the complex correlations between aging and economic behavior. This work not only deepens our understanding of the Japanese and American economic landscapes but, through careful examination of the comparative social and economic data, clarifies the complex relation between aging societies, public policies, and economic outcomes.

In higher education, the United States is the preeminent global leader, dominating the list of the world's top research universities. But there are signs that its position of global leadership will face challenges in the future, as it has in other realms of international competition. This book addresses the variety of issues crucial to understanding this preeminence and this challenge. It examines the various factors that contributed to America's success in higher education, including openness to people and ideas, generous governmental support, and a tradition of decentralized friendly competition. The book also explores the advantages of holding a dominant position in this marketplace and examines the current state of American higher education in a comparative context, placing particular emphasis on how market forces affect universities. By discussing the differences in quality among students and institutions around the world, it sheds light on the singular aspects of American higher education.

This book provides a massive amount of new research on several popular and less-examined topics pertaining to the relationship between economics and aging. Among the many themes explored in this volume, considerable attention is given to new research on retirement savings, the cost and efficiency of medical resources, and the predictors of health events. The volume begins with a discussion of the risks and merits of 401(k) plans. Subsequent chapters present recent analysis of the growth of Medicare costs; the different aspects of disability; and the evolution of health, wealth, and living arrangements over the life course. Keeping with the global tradition of previous volumes, the book also includes comparative studies on savings behavior in Italy, the Netherlands, and the United States; an examination of household savings among different age groups in Germany; and a chapter devoted to population aging and the plight of widows in India.
