Global Productivity


Book Description

The COVID-19 pandemic struck the global economy after a decade that featured a broad-based slowdown in productivity growth. Global Productivity: Trends, Drivers, and Policies presents the first comprehensive analysis of the evolution and drivers of productivity growth, examines the effects of COVID-19 on productivity, and discusses a wide range of policies needed to rekindle productivity growth. The book also provides a far-reaching data set of multiple measures of productivity for up to 164 advanced economies and emerging market and developing economies, and it introduces a new sectoral database of productivity. The World Bank has created an extraordinary book on productivity, covering a large group of countries and using a wide variety of data sources. There is an emphasis on emerging and developing economies, whereas the prior literature has concentrated on developed economies. The book seeks to understand growth patterns and quantify the role of (among other things) the reallocation of factors, technological change, and the impact of natural disasters, including the COVID-19 pandemic. This book is must-reading for specialists in emerging economies but also provides deep insights for anyone interested in economic growth and productivity. Martin Neil Baily Senior Fellow, The Brookings Institution Former Chair, U.S. President’s Council of Economic Advisers This is an important book at a critical time. As the book notes, global productivity growth had already been slowing prior to the COVID-19 pandemic and collapses with the pandemic. If we want an effective recovery, we have to understand what was driving these long-run trends. The book presents a novel global approach to examining the levels, growth rates, and drivers of productivity growth. For anyone wanting to understand or influence productivity growth, this is an essential read. Nicholas Bloom William D. Eberle Professor of Economics, Stanford University The COVID-19 pandemic hit a global economy that was already struggling with an adverse pre-existing condition—slow productivity growth. This extraordinarily valuable and timely book brings considerable new evidence that shows the broad-based, long-standing nature of the slowdown. It is comprehensive, with an exceptional focus on emerging market and developing economies. Importantly, it shows how severe disasters (of which COVID-19 is just the latest) typically harm productivity. There are no silver bullets, but the book suggests sensible strategies to improve growth prospects.

Optimal Product Variety, Scale Effects, and Growth


Book Description

We develop a model to analyze the social optimality of growth and product variety. The model contains two sectors, one assembly sector producing a homogeneous consumption good and one intermediate goods sector producing differentiated inputs. Growth results from R&D performed in the intermediate goods sector. We disentangle three effects associated with increased variety: (i) a productivity effect, (ii) a business stealing effect, and (iii) a growth effect. The market provides too little variety and suboptimally high growth if the productivity effect of variety is large relative to the market power of intermediate goods producers. If varieties are not very productive, the market provides too low a rate of growth, whereas variety may either be too low as well too high.




Coping with Variety


Book Description

First published in 1999, this book explores pint points, compares and dates the development of product differentiation and variety. This book also analyses’ how firms have embraced a variety of ways of efficiently managing this verity though production, the design of the product as well as in the relations with the suppliers and distributors.




Long-Term Factors in American Economic Growth


Book Description

These classic studies of the history of economic change in 19th- and 20th-century United States, Canada, and British West Indies examine national product; capital stock and wealth; and fertility, health, and mortality. "A 'must have' in the library of the serious economic historian."—Samuel Bostaph, Southern Economic Journal




Sources of Productivity Growth


Book Description

Over the past few decades there have been surges in productivity in a number of countries, in particular in the UK under the Thatcher government. Explanations of these changes have not been satisfactory. This compelling 1996 book examines the data relating to these changes at an individual establishment level. Chapters cover the UK, the USA, Canada, Japan, Australia, Belgium, Norway and Sweden, and comparisons also include Germany and the Netherlands. Using a variety of the most up-to-date methods of analysis, the contributors show that there is no single simple explanation. Changes in competitive conditions, skills, innovation and the growth of small firms all have their part to play, as does the widespread closure of the least productive establishments.




Productivity Analysis


Book Description

There is a wide variety of perspectives for productivity analysis. The back grounds of different researchers and practitioners who work on this topic include such fields as economics, business administration, and industrial engineering, among others. Within each such field, there are different schools of thought on the theory and application of productivity analysis. Often it is not difficult to observe a lack of communication among the advocates of these separate schools. The purpose of this book is to present in a single volume samples of alternative approaches to productivity analy sis. This may be considered as a first step toward a better communication among practitioners and researchers in the fields of management, industrial engineering, and economics. The focus of the book is on the United States, where the productivity growth problem has been acute for some time. The book begins with a brief overview chapter that covers some of the issues involved in productivity analysis and a sample of methodological ap proaches presently in use. After this introduction, we move to Chapter 2 where Solomon Fabricant presents the issues related to measurement and analysis at the macroeconomic level. In Chapter 3, C. Lowell Harriss discusses concepts that he considers es sential for productivity growth: capital formation, technological progress, and freedom.




The Economics of Growth


Book Description

A comprehensive, rigorous, and up-to-date introduction to growth economics that presents all the major growth paradigms and shows how they can be used to analyze the growth process and growth policy design. This comprehensive introduction to economic growth presents the main facts and puzzles about growth, proposes simple methods and models needed to explain these facts, acquaints the reader with the most recent theoretical and empirical developments, and provides tools with which to analyze policy design. The treatment of growth theory is fully accessible to students with a background no more advanced than elementary calculus and probability theory; the reader need not master all the subtleties of dynamic programming and stochastic processes to learn what is essential about such issues as cross-country convergence, the effects of financial development on growth, and the consequences of globalization. The book, which grew out of courses taught by the authors at Harvard and Brown universities, can be used both by advanced undergraduate and graduate students, and as a reference for professional economists in government or international financial organizations. The Economics of Growth first presents the main growth paradigms: the neoclassical model, the AK model, Romer's product variety model, and the Schumpeterian model. The text then builds on the main paradigms to shed light on the dynamic process of growth and development, discussing such topics as club convergence, directed technical change, the transition from Malthusian stagnation to sustained growth, general purpose technologies, and the recent debate over institutions versus human capital as the primary factor in cross-country income differences. Finally, the book focuses on growth policies—analyzing the effects of liberalizing market competition and entry, education policy, trade liberalization, environmental and resource constraints, and stabilization policy—and the methodology of growth policy design. All chapters include literature reviews and problem sets. An appendix covers basic concepts of econometrics.
