Why Is Labor Receiving A Smaller Share Of Global Income Theory And Empirical Evidence

This paper documents the downward trend in the labor share of global income since the early 1990s, as well as its heterogeneous evolution across countries, industries and worker skill groups, using a newly assembled dataset, and analyzes the drivers behind it. Technological progress, along with varying exposure to routine occupations, explains about half the overall decline in advanced economies, with a larger negative impact on middle-skilled workers. In emerging markets, the labor share evolution is explained predominantly by global integration, particularly the expansion of global value chains that contributed to raising the overall capital intensity in production.

This book is about labor income share, which measures the share of national income paid in wages. The global share of income going towards labor is declining, which suggests a more unequal distribution of income. This has sparked debates about fair distribution of personal incomes among academics and policymakers alike. This book joins the discussion by bringing together recent developments in theoretical and empirical research on labor income share and novel insights on the measurement of the labor income share. The aim of this book is to help design policies to reduce inequality and provide useful knowledge to academics, policymakers from government agencies, policy aides in research institutions and think tanks, and broader audiences from public and private organizations.

Labor market deregulation, intended to boost productivity and employment, is one plausible, yet little studied, driver of the decline in labor shares that took place across most advanced economies since the early 1990s. This paper assesses the impact of job protection deregulation in a sample of 26 advanced economies over the period 1970-2015, using a newly constructed dataset of major reforms to employment protection legislation for regular contracts. We apply the local projection method to estimate the dynamic response of the labor share to our reform events at both the country and the country-industry levels. For the latter, we employ a differences-in-differences identification strategy using two identifying assumptions grounded in theory—namely that job protection deregulation should have larger negative effects in industries characterized by (i) a higher “natural” propensity to adjust the workforce, and (ii) a lower elasticity of substitution between capital and labor. We find a statistically significant, economically large and robust negative effect of deregulation on the labor share. In particular, illustrative back-of-the-envelope calculations suggest that job protection deregulation may have contributed about 15 percent to the average labor share decline in advanced economies. Together with existing evidence regarding the macroeconomic gains from job protection and other labor market reforms, our results also point to the need for policymakers to address efficiency-equity trade-offs when designing such reforms.

About 27.5 million Americans—nearly 24 percent of the labor force—earn less than $8.70 an hour, not enough to keep a family of four out of poverty, even working full-time year-round. Job ladders for these workers have been dismantled, limiting their ability to get ahead in today's labor market. Low-Wage America is the most extensive study to date of how the choices employers make in response to economic globalization, industry deregulation, and advances in information technology affect the lives of tens of millions of workers at the bottom of the wage distribution. Based on data from hundreds of establishments in twenty-five industries—including manufacturing, telecommunications, hospitality, and health care—the case studies document how firms' responses to economic restructuring often results in harsh working conditions, reduced benefits, and fewer opportunities for advancement. For instance, increased pressure for profits in newly consolidated hotel chains has led to cost-cutting strategies such as requiring maids to increase the number of rooms they clean by 50 percent. Technological changes in the organization of call centers—the ultimate "disposable workplace"—have led to monitoring of operators' work performance, and eroded job ladders. Other chapters show how the temporary staffing industry has provided paths to better work for some, but to dead end jobs for many others; how new technology has reorganized work in the back offices of banks, raising skill requirements for workers; and how increased competition from abroad has forced U.S. manufacturers to cut costs by reducing wages and speeding production. Although employers' responses to economic pressures have had a generally negative effect on frontline workers, some employers manage to resist this trend and still compete successfully. The benefits to workers of multi-employer training consortia and the continuing relevance of unions offer important clues about what public policy can do to support the job prospects of this vast, but largely overlooked segment of the American workforce. Low-Wage America challenges us to a national self-examination about the nature of low-wage work in this country and asks whether we are willing to tolerate the profound social and economic consequences entailed by these jobs.

The Economic and Fiscal Consequences of Immigration finds that the long-term impact of immigration on the wages and employment of native-born workers overall is very small, and that any negative impacts are most likely to be found for prior immigrants or native-born high school dropouts. First-generation immigrants are more costly to governments than are the native-born, but the second generation are among the strongest fiscal and economic contributors in the U.S. This report concludes that immigration has an overall positive impact on long-run economic growth in the U.S. More than 40 million people living in the United States were born in other countries, and almost an equal number have at least one foreign-born parent. Together, the first generation (foreign-born) and second generation (children of the foreign-born) comprise almost one in four Americans. It comes as little surprise, then, that many U.S. residents view immigration as a major policy issue facing the nation. Not only does immigration affect the environment in which everyone lives, learns, and works, but it also interacts with nearly every policy area of concern, from jobs and the economy, education, and health care, to federal, state, and local government budgets. The changing patterns of immigration and the evolving consequences for American society, institutions, and the economy continue to fuel public policy debate that plays out at the national, state, and local levels. The Economic and Fiscal Consequences of Immigration assesses the impact of dynamic immigration processes on economic and fiscal outcomes for the United States, a major destination of world population movements. This report will be a fundamental resource for policy makers and law makers at the federal, state, and local levels but extends to the general public, nongovernmental organizations, the business community, educational institutions, and the research community.

This paper analyzes the extent of income inequality from a global perspective, its drivers, and what to do about it. The drivers of inequality vary widely amongst countries, with some common drivers being the skill premium associated with technical change and globalization, weakening protection for labor, and lack of financial inclusion in developing countries. We find that increasing the income share of the poor and the middle class actually increases growth while a rising income share of the top 20 percent results in lower growth—that is, when the rich get richer, benefits do not trickle down. This suggests that policies need to be country specific but should focus on raising the income share of the poor, and ensuring there is no hollowing out of the middle class. To tackle inequality, financial inclusion is imperative in emerging and developing countries while in advanced economies, policies should focus on raising human capital and skills and making tax systems more progressive.

This paper provides new evidence of the effect of monetary policy shocks on income inequality. Using a measure of unanticipated changes in policy rates for a panel of 32 advanced and emerging market countries over the period 1990-2013, the paper finds that contractionary (expansionary) monetary actions increase (reduce) income inequality. The effect, however, varies over time, depending on the type of the shocks (tightening versus expansionary monetary policy) and the state of the business cycle, and across countries depending on the share of labor income and redistribution policies. In particular, we find that the effect is larger for positive monetary policy shocks, especially during expansions. Looking across countries, we find that the effect is larger in countries with higher labor share of income and smaller redistribution policies. Finally, while an unexpected increase in policy rates increases inequality, changes in policy rates driven by an increase in growth are associated with lower inequality.

This is the first study that puts together a comprehensive and in-depth analysis of the drivers of the labor income share across a number of countries in Asia. This book provides an insightful companion to the study of labor income shares that plays a vital role in understanding the relationship between national income and personal income, and the relationship between wage inequality and wealth inequality. The timing of the book is ideal, as the ongoing debate over a global decline in the labor income share is far from settled. To this extent, evidence from the Asian countries is mixed. The labor income share in some Asian countries has been rising since the 1990s. The purpose of this edited volume is to gain more insights on the potential drivers of the Asian experience. The first half of the book pays attention to the measurement problems related to the earnings of self-employed and workers in the informal sector. Then it puts together country case studies examining a wide range of factors driving the labor income share in Asia.
