A Washington Post Notable Nonfiction Book for 2011 With the British Industrial Revolution, part of the world's population started to experience extraordinary economic growth—leading to enormous gaps in wealth and living standards between the industrialized West and the rest of the world. This pattern of divergence reversed after World War II, and now we are midway through a century of high and accelerating growth in the developing world and a new convergence with the advanced countries—a trend that is set to reshape the world. Michael Spence, winner of the Nobel Prize in Economic Sciences, explains what happened to cause this dramatic shift in the prospects of the five billion people who live in developing countries. The growth rates are extraordinary, and continuing them presents unprecedented challenges in governance, international coordination, and ecological sustainability. The implications for those living in the advanced countries are great but little understood. Spence clearly and boldly describes what's at stake for all of us as he looks ahead to how the global economy will develop over the next fifty years. The Next Convergence is certain to spark a heated debate how best to move forward in the post-crisis period and reset the balance between national and international economic interests, and short-term fixes and long-term sustainability.

There are many different types of convergence within economics, as well as several methods to analyse each of them. This book addresses the concept of real economic convergence or the gradual levelling-off of GDP (gross domestic product) per capita rates across economies. In addition to a detailed, holistic overview of the history and theory, the authors include a description of two modern methods of assessing the occurrence and rate of convergence, BMA-based and HMM-based, as well as the results of the empirical analysis. Readers will have access not only to the conventional econometric approach of β convergence but also to an alternative one, allowing for the convergence issue to be expressed in the context of automatic pattern recognition. This approach is universal as it can be adapted to a variety of input data. The lowest aggregation level study investigates regional convergence through the case of Polish voivodships, where convergence towards the leader is tested. On a higher level of aggregation, the authors examine the existence of GDP convergence in such groups as the EU28, North Africa and the Middle East, sub-Saharan Africa, South America, Caribbean, South-East Asia, Australia and Oceania, or post-socialist countries. For each group, the real β convergence is tested using the two above-mentioned approaches. The results are widely discussed, broadly illustrated, interpreted, and compared. The analysis allows readers to draw interesting conclusions about the causes of convergence or the drivers behind divergence. The book will stimulate further research in the field, but the research was conducted from the point of view of individual countries.

The NBER Macroeconomics Annual 2021 presents research-central issues in contemporary macroeconomics. Robert Hall and Marianna Kudlyak examine unemployment dynamics during economic recoveries. They present new empirical findings and explore models in which the labor market gradually draws down the stock of unemployed workers in the aftermath of a downturn. Titan Alon, Sena Coskun, Matthias Doepke, David Koll, and Michèle Tertilt analyze the relative decline in employment of women during the COVID-19 pandemic and the associated global recession. They show that increased childcare needs, which fell more heavily on women, and differences in occupations both contributed. In the case of the US, however, each of these factors account for less than 20% of the gender gap in hours worked during the pandemic. Richard Rogerson and Johanna Wallenius study the employment rates of older workers in OECD countries over the last forty years. An expansion of institutions incentivizing retirement, concurrent with negative aggregate shocks between 1970 and 1995, led to falling employment rates. This trend started to reverse in the mid-1990s when many of these institutions, such as public pension programs, were cut back. Michael Barnett, William Brock, and Lars Peter Hansen explore the consequences of risk, ambiguity, and model misspecification in climate policy design. They consider carbon emissions pricing and the effects of different sources of uncertainty--such as future information about environmental damage, uncertainties in carbon and temperature dynamics and damage functions, and the role of future green technologies--on policy design. Michael Kremer, Jack Willis, and Yang You present new evidence suggesting a steady trend toward income convergence across countries since the late 1980s. They find convergence in various determinants of economic growth across countries and a flattening of the relationship between growth and these determinants. The paper challenges theories of growth arising after earlier rejections of the neoclassical growth model.

The long-awaited second edition of an important textbook on economic growth—a major revision incorporating the most recent work on the subject. This graduate level text on economic growth surveys neoclassical and more recent growth theories, stressing their empirical implications and the relation of theory to data and evidence. The authors have undertaken a major revision for the long-awaited second edition of this widely used text, the first modern textbook devoted to growth theory. The book has been expanded in many areas and incorporates the latest research. After an introductory discussion of economic growth, the book examines neoclassical growth theories, from Solow-Swan in the 1950s and Cass-Koopmans in the 1960s to more recent refinements; this is followed by a discussion of extensions to the model, with expanded treatment in this edition of heterogenity of households. The book then turns to endogenous growth theory, discussing, among other topics, models of endogenous technological progress (with an expanded discussion in this edition of the role of outside competition in the growth process), technological diffusion, and an endogenous determination of labor supply and population. The authors then explain the essentials of growth accounting and apply this framework to endogenous growth models. The final chapters cover empirical analysis of regions and empirical evidence on economic growth for a broad panel of countries from 1960 to 2000. The updated treatment of cross-country growth regressions for this edition uses the new Summers-Heston data set on world income distribution compiled through 2000.
