Book excerpt: Measuring Economic Growth and Productivity: Foundations, KLEMS Production Models, and Extensions presents new insights into the causes, mechanisms and results of growth in national and regional accounts. It demonstrates the versatility and usefulness of the KLEMS databases, which generate internationally comparable industry-level data on outputs, inputs and productivity. By rethinking economic development beyond existing measurements, the book's contributors align the measurement of growth and productivity to contemporary global challenges, addressing the need for measurements as well as the Gross Domestic Product. All contributors in this foundational volume are recognized experts in their fields, all inspired by the path-breaking research of Dale W. Jorgenson. - Demonstrates how an approach based on sources of economic growth (KLEMS – capital, labor, energy, materials and services) can be used to analyze economic growth and productivity - Includes examples covering the G7, E7, EU, Latin America, Norway, China, Taiwan, Japan, Korea, India and other South Asian countries - Examines the effects of digital, information, communication and integrated technologies on national and regional economies

Book excerpt: Since the Great Depression, researchers and statisticians have recognized the need for more extensive methods for measuring economic growth and sustainability. The recent recession renewed commitments to closing long-standing gaps in economic measurement, including those related to sustainability and well-being. The latest in the NBER’s influential Studies in Income and Wealth series, which has played a key role in the development of national account statistics in the United States and other nations, this volume explores collaborative solutions between academics, policy researchers, and official statisticians to some of today’s most important economic measurement challenges. Contributors to this volume extend past research on the integration and extension of national accounts to establish an even more comprehensive understanding of the distribution of economic growth and its impact on well-being, including health, human capital, and the environment. The research contributions assess, among other topics, specific conceptual and empirical proposals for extending national accounts.

Book excerpt: Australia continues to be at the forefront of international work on measuring and promoting wellbeing, Ian Castles being a significant contributor over the last forty years as an official and academic. This book combines a selection of Castles’ important work with contemporary research from a range of contributors. The material is in four parts: 1. The role of economics in defining and promoting wellbeing 2. Measuring real income and wellbeing 3. Measuring inequality 4. Climate change and the limits to growth. The issues canvassed are both long-standing and current. Does economic growth contribute to wellbeing? How different is income to wellbeing? How do we measure societal wellbeing and take its distribution into account? The book will be of value to all those looking to informed debate on global challenges such as reducing poverty, sustaining the environment and advancing the quality of life, including politicians, commentators, officials and academics.

Book excerpt: This text is designed to provide a comprehensive guide to students, researchers, or consultants who wish to carry out and to interpret analyses of economic performance, with an emphasis on productivity growth. The text includes an overview of standard productivity growth measurement techniques and adaptations, and data construc tion procedures. It goes further, however, by expanding the tradition al growth accounting (index number) framework to allow consider ation of how different aspects of firm behavior underlying productivity growth are interrelated, how they can be measured con sistently in a parametric model, and how they permit a well-defined decomposition of standard productivity growth measures. These ideas are developed by considering in detail a number of underlying theoretical results and econometric issues. The impacts of various production characteristics on productivity growth trends are also evaluated by overviewing selected methodological extensions and em pirical evidence. More specifically, in the methodological extensions, emphasis is placed on incorporation of cost and demand characteristics, such as fixity and adjustment costs, returns to scale, and the existence of market power, into analyses of productivity growth. These character istics, generally disregarded in such analyses, can have very important impacts on production structure and firm behavior, and thus on economic performance. They also provide the conceptual basis for vii viii PREFACE measures that are often used independently as indicators of economic performance, such as investment, capacity utilization, and profit measures.

Book excerpt: A provocative critique of the pieties and fallacies of our obsession with economic growth We live in a society in which a priesthood of economists, wielding impenetrable mathematical formulas, set the framework for public debate. Ultimately, it is the perceived health of the economy which determines how much we can spend on our schools, highways, and defense; economists decide how much unemployment is acceptable and whether it is right to print money or bail out profligate banks. The backlash we are currently witnessing suggests that people are turning against the experts and their faulty understanding of our lives. Despite decades of steady economic growth, many citizens feel more pessimistic than ever, and are voting for candidates who voice undisguised contempt for the technocratic elite. For too long, economics has relied on a language which fails to resonate with people's actual experience, and we are now living with the consequences. In this powerful, incisive book, David Pilling reveals the hidden biases of economic orthodoxy and explores the alternatives to GDP, from measures of wealth, equality, and sustainability to measures of subjective wellbeing. Authoritative, provocative, and eye-opening, The Growth Delusion offers witty and unexpected insights into how our society can respond to the needs of real people instead of pursuing growth at any cost.

Book excerpt: Today's leading economists weigh in with a new "dashboard" of metrics for measuring our economic and social health "What we measure affects what we do. If we focus only on material well-being—on, say, the production of goods, rather than on health, education, and the environment—we become distorted in the same way that these measures are distorted." —Joseph E. Stiglitz A consensus has emerged among key experts that our conventional economic measures are out of sync with how most people live their lives. GDP, they argue, is a poor and outmoded measure of our well-being. The global movement to move beyond GDP has attracted some of the world's leading economists, statisticians, and social thinkers who have worked collectively to articulate new approaches to measuring economic well-being and social progress. In the decade since the 2008 economic crisis, these experts have come together to determine what indicators can actually tell us about people's lives. In the first book of its kind, leading economists from around the world, including Thomas Piketty, Emmanuel Saez, Elizabeth Beasely, Jacob Hacker, François Bourguignon, Nora Lustig, Alan B. Krueger, and Joseph E. Stiglitz, describe a range of fascinating metrics—from economic insecurity and environmental sustainability to inequality of opportunity and levels of trust and resilience—that can be used to supplement the simplistic measure of gross domestic product, providing a far more nuanced and accurate account of societal health and well-being. This groundbreaking volume is sure to provide a major source of ideas and inspiration for one of the most important intellectual movements of our time.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, concerns about the outcomes and nature of economic growth have given way to a new emphasis on its quality. This volume brings together prominent international contributors to consider a range of interrelated questions concerning the quality of growth in Africa, with a primary focus on sub-Saharan countries. Contributors discuss the measurement of growth, the transformations necessary to sustain it, and issues around equity and well-being. They consider topics such as the distribution of income gains from growth; the extent to which economic growth has resulted in improvements in employment, poverty, and security; structural transformations of the economy and diversification of the sources of growth; environmental sustainability; and management of urbanization. Offering both diagnoses and prescriptions, The Quality of Growth in Africa helps envision a future that goes beyond increasing GDP to ensuring that growth translates into advancements in well-being. Although the book focuses on sub-Saharan Africa, much of the contributors’ incisive analysis has implications for countries outside the region.

Available in PDF, EPUB and Kindle. Book excerpt: How did Americans come to quantify their society’s progress and well-being in units of money? In today’s GDP-run world, prices are the standard measure of not only our goods and commodities but our environment, our communities, our nation, even our self-worth. The Pricing of Progress traces the long history of how and why we moderns adopted the monetizing values and valuations of capitalism as an indicator of human prosperity while losing sight of earlier social and moral metrics that did not put a price on everyday life. Eli Cook roots the rise of economic indicators in the emergence of modern capitalism and the contested history of English enclosure, Caribbean slavery, American industrialization, economic thought, and corporate power. He explores how the maximization of market production became the chief objective of American economic and social policy. We see how distinctly capitalist quantification techniques used to manage or invest in railroad corporations, textile factories, real estate holdings, or cotton plantations escaped the confines of the business world and seeped into every nook and cranny of society. As economic elites quantified the nation as a for-profit, capitalized investment, the progress of its inhabitants, free or enslaved, came to be valued according to their moneymaking abilities. Today as in the nineteenth century, political struggles rage over who gets to determine the statistical yardsticks used to gauge the “health” of our economy and nation. The Pricing of Progress helps us grasp the limits and dangers of entrusting economic indicators to measure social welfare and moral goals.

Available in PDF, EPUB and Kindle. Book excerpt: Reimagining our global economy so it becomes more sustainable and prosperous for all Our global economic system is broken. But we can replace the current picture of global upheaval, unsustainability, and uncertainty with one of an economy that works for all people, and the planet. First, we must eliminate rising income inequality within societies where productivity and wage growth has slowed. Second, we must reduce the dampening effect of monopoly market power wielded by large corporations on innovation and productivity gains. And finally, the short-sighted exploitation of natural resources that is corroding the environment and affecting the lives of many for the worse must end. The debate over the causes of the broken economy—laissez-faire government, poorly managed globalization, the rise of technology in favor of the few, or yet another reason—is wide open. Stakeholder Capitalism: A Global Economy that Works for Progress, People and Planet argues convincingly that if we don't start with recognizing the true shape of our problems, our current system will continue to fail us. To help us see our challenges more clearly, Schwab—the Founder and Executive Chairman of the World Economic Forum—looks for the real causes of our system's shortcomings, and for solutions in best practices from around the world in places as diverse as China, Denmark, Ethiopia, Germany, Indonesia, New Zealand, and Singapore. And in doing so, Schwab finds emerging examples of new ways of doing things that provide grounds for hope, including: Individual agency: how countries and policies can make a difference against large external forces A clearly defined social contract: agreement on shared values and goals allows government, business, and individuals to produce the most optimal outcomes Planning for future generations: short-sighted presentism harms our shared future, and that of those yet to be born Better measures of economic success: move beyond a myopic focus on GDP to more complete, human-scaled measures of societal flourishing By accurately describing our real situation, Stakeholder Capitalism is able to pinpoint achievable ways to deal with our problems. Chapter by chapter, Professor Schwab shows us that there are ways for everyone at all levels of society to reshape the broken pieces of the global economy and—country by country, company by company, and citizen by citizen—glue them back together in a way that benefits us all.

While updating and clarifying the 1968 SNA, the 1993 SNA provides the basis for improving compilation of national accounts statistics, promoting integration of economic and related statistics, and enhancing analysis of economic developments. The 1993 SNA deals more clearly with relationships between economic flows (such as production, income, savings, accumulation, and financing) and links between these flows and stocks. At the same time the 1993 SNA reflects the many significant developments that have taken place in financial markets and completes the integration of balance sheets into the system. The 1993 SNA also suggests how satellite accounts (e.g. environmental accounts) and alternative classifications (e.g., through social accounting matrices) an be used to augment the central framework of the system.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains papers presented at a conference in May 1988 in Washington, D.C., commemorating the fiftieth anniversary of the founding of the Conference on Research in Income and Wealth (CRIW). The call for papers emphasized assessments of broad topics in economic measurement, both conceptual and pragmatic. The organizers desired (and succeeded in obtaining) a mix of papers that, first, illustrate the range of measurement issues that economics as a science must confront and, second, mark major milestones of CRIW accomplishment. The papers concern prices and output (Griliches, Pieper, Triplett) and also the major productive inputs, capital (Hulten) and labor (Hamermesh). Measures of saving, the source of capital accumulation, are covered in one paper (Boskin); measuring productivity, the source of much of the growth in per capita income, is reviewed in another (Jorgenson). The use of economic data in economic policy analysis and in regulation are illustrated in a review of measures of tax burden (Atrostic and Nunns) and in an analysis of the data needed for environmental regulation (Russell and Smith); the adequacy of data for policy analysis is evaluated in a roundtable discussion (chapter 12) involving four distinguished policy analysts with extensive government experience in Washington and Ottawa.

Available in PDF, EPUB and Kindle. Book excerpt: Few ideas in the past century have had wider financial, political, and governmental impact than that of economic growth. The common belief that endless economic growth, as measured by Gross Domestic Product, is not only possible but actually essential for the flourishing of civilization remains a powerful policy goal and aspiration for many. In The Mismeasure of Progress, Stephen J. Macekura exposes a historical road not taken, illuminating the stories of the activists, intellectuals, and other leaders who long argued that GDP growth was not all it was cracked up to be. Beginning with the rise of the growth paradigm in the 1940s and 1950s and continuing through the present day, The Mismeasure of Progress is the first book on the myriad thinkers who argued against growth and the conventional way progress had been measured and defined. For growth critics, questioning the meaning and measurement of growth was a necessary first step to creating a more just, equal, and sustainable world. These critics argued that focusing on growth alone would not resolve social, political, and environmental problems, and they put forth alternate methods for defining and measuring human progress. ?In today’s global political scene—marked by vast inequalities of power and wealth and made even more fraught by a global climate emergency—the ideas presented by these earlier critics of growth resonate more loudly than ever. Economic growth appealed to many political leaders because it allowed them to avoid addressing political trade-offs and class conflict. It sustained the fiction that humans are somehow separate from nonhuman “nature,” ignoring the intimate and dense connections between the two. In order to create a truly just and equitable society, Macekura argues, we need a clear understanding of our collective needs beyond growth and more holistic definitions of progress that transcend economic metrics like GDP.

Available in PDF, EPUB and Kindle. Book excerpt: E. Wayne Nafziger analyzes the economic development of Asia, Africa, Latin America, and East-Central Europe. The book is suitable for those with a background in economics principles. Nafziger explains the reasons for the recent fast growth of India, Poland, Brazil, China, and other Pacific Rim countries, and the slow, yet essential, growth for a turnaround of sub-Saharan Africa. The fifth edition of the text, written by a scholar of developing countries, is replete with real-world examples and up-to-date information. Nafziger discusses poverty, income inequality, hunger, unemployment, the environment and carbon-dioxide emissions, and the widening gap between rich (including middle-income) and poor countries. Other new components include the rise and fall of models based on Russia, Japan, China/Taiwan/Korea, and North America; randomized experiments to assess aid; an exploration of whether information technology and mobile phones can provide poor countries with a shortcut to prosperity; and a discussion of how worldwide financial crises, debt, and trade and capital markets affect developing countries.

Book excerpt: In spite of recurrent criticism and an impressive production of alternative indicators by scholars and NGOs, GDP remains the central indicator of countries' success. This book revisits the foundations of indicators of social welfare, and critically examines the four main alternatives to GDP that have been proposed: composite indicators, subjective well-being indexes, capabilities (the underlying philosophy of the Human Development Index), and equivalent incomes. Its provocative thesis is that the problem with GDP is not that it uses a monetary metric but that it focuses on a narrow set of aspects of individual lives. It is actually possible to build an alternative, more comprehensive, monetary indicator that takes income as its first benchmark and adds or subtracts corrections that represent the benefit or cost of non-market aspects of individual lives. Such a measure can respect the values and preferences of the people and give as much weight as they do to the non-market dimensions. A further provocative idea is that, in contrast, most of the currently available alternative indicators, including subjective well-being indexes, are not as respectful of people's values because, like GDP, they are too narrow and give specific weights to the various dimensions of life in a more uniform way, without taking account of the diversity of views on life in the population. The popular attraction that such alternative indicators derive from being non-monetary is therefore based on equivocation. Moreover, it is argued in this book that "greening" GDP and relative indicators is not the proper way to incorporate sustainability concerns. Sustainability involves predicting possible future paths, therefore different indicators than those assessing the current situation. While various indicators have been popular (adjusted net savings, ecological footprint), none of them involves the necessary forecasting effort that a proper evaluation of possible futures requires.
