A theoretical and empirical examination of wage differentials findsthat traditional theories of competition do not explain why workers with identical skills are paid differently.

The distribution of income, the rate of pay raises, and the mobility of employees is crucial to understanding labor economics. Although research abounds on the distribution of wages across individuals in the economy, wage differentials within firms remain a mystery to economists. The first effort to examine linked employer-employee data across countries, The Structure of Wages:An International Comparison analyzes labor trends and their institutional background in the United States and eight European countries. A distinguished team of contributors reveal how a rising wage variance rewards star employees at a higher rate than ever before, how talent becomes concentrated in a few firms over time, and how outside market conditions affect wages in the twenty-first century. From a comparative perspective that examines wage and income differences within and between countries such as Denmark, Italy, and the Netherlands, this volume will be required reading for economists and those working in industrial organization.

Designing a good unemployment insurance scheme is a delicate matter. In a system with no or little insurance, households may be subject to a high income risk, whereas excessively generous unemployment insurance systems are known to lead to high unemployment rates and are costly both from a fiscal perspective and for society as a whole. Andreas Pollak investigates what an optimal unemployment insurance system would look like, i.e. a system that constitutes the best possible compromise between income security and incentives to work. Using theoretical economic models and complex numerical simulations, he studies the effects of benefit levels and payment durations on unemployment and welfare. As the models allow for considerable heterogeneity of households, including a history-dependent labor productivity, it is possible to analyze how certain policies affect individuals in a specific age, wealth or skill group. The most important aspect of an unemployment insurance system turns out to be the benefits paid to the long-term unemployed. If this parameter is chosen too high, a large number of households may get caught in a long spell of unemployment with little chance of finding work again. Based on the predictions in these models, the so-called "Hartz IV" labor market reform recently adopted in Germany should have highly favorable effects on the unemployment rates and welfare in the long run.

Known for his seminal work in efficiency-wage theory, Andrew Weiss surveys recent research in the field and presents new results. He shows how wage schedules affect the kinds of workers a firm employs and how well those workers perform on the job. Using straightforward examples, he demonstrates how efficiency-wage theory can explain labor market outcomes and guide government policy. There is a separate section of applications to less developed countries. "Efficiency-wage models represent one of the most important developments in economic theory of recent years. They have, at last, provided integrated explanations both of macroeconomic phenomena, such as unemployment and wage rigidity, and microeconomic phenomena, such as wage dispersion. Weiss--one of the pioneers of efficiency-wage theory--provides here a masterful survey, a lucid and systematic and yet critical account of this rapidly developing branch of economics. This book should be required reading in all courses in macroeconomics."--Joseph Stiglitz, Stanford University "Efficiency Wages should be on the bookshelf of all labor and macroeconomists."--Lawrence H. Summers, Harvard University "A splendid monograph ... most readable... I will put it on my reading list."--Partha Dasgupta, Stanford University Originally published in 1991. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

What caused the decline in wage inequality of the 2000s in Latin America? Looking to the future, will the current economic slowdown be regressive? Wage Inequality in Latin America: Understanding the Past to Prepare for the Future addresses these two questions by reviewing relevant literature and providing new evidence on what we know from the conceptual, empirical, and policy perspectives. The answer to the fi rst question can be broken down into several parts, although the bottom line is that the changes in wage inequality resulted from a combination of three forces: (a) education expansion and its eff ect on falling returns to skill (the supply-side story); (b) shifts in aggregate domestic demand; and (c) exchange rate appreciation from the commodity boom and the associated shift to the nontradable sector that changed interfi rm wage diff erences. Other forces had a non-negligible but secondary role in some countries, while they were not present in others. These include the rapid increase of the minimum wage and a rapid trend toward formalization of employment, which played a supporting role but only during the boom. Understanding the forces behind recent trends also helps to shed light on the second question. The analysis in this volume suggests that the economic slowdown is putting the brakes on the reduction of inequality in Latin America and will likely continue to do so—but it might not actually reverse the region’s movement toward less wage inequality.

This volume seeks to go beyond the microeconomic view of wages as a cost having negative consequences on a given firm, to consider the positive macroeconomic dynamics associated with wages as a major component of aggregate demand.

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.
