Skill-biased technical change, educational choice, and labor market polarization: the U.S. versus Europe

This paper analyzes the effect of recent technical change on the labor market and explains the observed differences in wage inequality among advanced countries. In particular, we focus on the difference between the inequality in the U.S. and in continental Europe. Many studies have indicated a rise in wage inequality in the U.S. over the past three decades. On the other hand, there has been little change in wage inequality in continental Europe. By introducing human capital investment into the model by Acemoglu (Am Econ Rev 89:1259–1278, 1999), we show that ex ante homogeneous economies would have distinct ex post wage distribution. The strategic complementarity between human capital investment and firms’ hiring strategies yields the possibility that multiple equilibria exist, which explains the difference in wage distribution between the U.S. and Europe. In addition, we show that differences in tax or education systems can explain the difference in wage distribution between the U.S. and Europe.     

The Allocation of Blacks in Large Firms and Establishments and Black-White Wage Inequality in the U.S. Economy

Using data from the National Longitudinal Survey of Youth (NLSY) for 1988, this study analyzes the allocation of African Americans in large firms and establishments and the effects of the allocation process on Black-White wage inequality. The results show that Blacks are disproportionately employed in large establishments while being under-represented in supervisory positions. The Black-White wage differential, however, remains significant only in the large establishments, despite this study's use of detailed controls for worker quality.     

The Decomposition of Firm-size Wage Differentials

No completely satisfactory explanation for the persistent and well-documented large-firm wage premium has been found. I use a novel adaptation of the Oaxaca/Blinder wage discrimination model to examine the firm-size wage differential which allows the wage differential to be decomposed into the portions attributable to (1) differences in employee endowments, (2) how the firm values these endowments, and (3) residual differences. Small firms actually pay higher wages based on how they value their workers’ endowments, but this wage premium was overshadowed by the superior endowments of workers in large firms and a residual differential in favor of large firms.

Verteilungseffekte von Finanzialisierung

Financialisation is often associated with rising income inequality. The article describes the major aspects of financialisation in the foreign, financial, business and household sector, and identifies several hypotheses how financialisation affects functional income distribution. We discuss enhanced exit options of firms, rising financial overhead costs for businesses, increased competition in capital markets, and weakened bargaining power of workers due to indebtedness. The different hypotheses are operationalised through empirical measures and their effect on the wage share is tested econometrically by means of a panel data set of 14 OECD countries over the period 1992–2014. We find statistically significant negative effects of financial payments of firms and financial openness on the wage share.     

Wage Inequality and Performance in Nonprofit and For‐Profit Organizations

This article examines the effects of several forms of wage inequality on service quality and employee effort. We suggest that two popular theories, tournament and fair wage/equity, are not necessarily competing. Each theory accurately describes aspects of employee behavior, but because of sectoral differences in organizational objectives and employee attitudes, tournament theory's predictions are relatively stronger in the for‐profit sector, while fair wage/equity theory's predictions are relatively stronger in the nonprofit sector. Using an employer–employee matched data set of nursing homes linked to a federal regulatory database and a resident survey, we found that ownership moderates the relationship between wage inequality and service quality. Although wage inequality positively affects service quality in the for‐profit sector, the reverse is true among nonprofit organizations. We also found that overall wage inequality in the workplace has a more pronounced influence on employee discretionary effort than does the employee's place in the distribution of wages.     

Decomposition of Changes in Korean Wage Inequality, 1998–2007

South Korea experienced a steep increase in wage inequality between the Asian financial crisis in 1997 and the global financial crisis in 2008. This paper investigates the causes of the sharp change during that time period by looking at the contributions of changes in the distributions of schooling and unionization. The effects are estimated applying two robust distributional function based decomposition methods on Korean Labor and Panel Survey data for the time period 1998–2007. The results suggest changes in the distribution of schooling can explain about 10 % of the changes in the 90/50 percentile wage gap. The declining unionization rate does not have much impact on the upward trend of Korean wage inequality. In addition, aggregate decomposition results suggest that changes in labor force composition can explain a significant proportion of the total wage changes in the upper-tail of the distribution. Based on our findings we provide a list of policy recommendations to address the wage inequality issue in Korea.     

FINANCIAL DEVELOPMENT AND WAGE INEQUALITY: THEORY AND EVIDENCE

We argue that financial market development contributed to the rise in the skill premium and residual wage inequality in the United States since the 1980s. We present an endogenous growth model with imperfect credit markets and establish how improving the efficiency of these markets affects modes of production, innovation, and wage dispersion between skilled and unskilled workers. The experience of U.S. states following banking deregulation provides empirical support for our hypothesis. We find that wages of skilled workers increased by between 0.5% and 6.3% following deregulation while those of unskilled workers fell by between 3.5% and 8.7%. Similarly, residual (or within‐group) inequality increased; the 90–50 percentile ratio of residuals from a Mincerian wage regression and their standard deviation increased by 4.2% and 1.7%, respectively.

Sex Inequality at Higher Levels in the Hierarchy: An Intraorganizational Perspective

The relationship of sex-based wage inequality to level in the hierarchy is investigated for 2,631 employees of a large financial services organization. As hypothesized, men earned more than women overall, and the wage gap between men and women was greater at higher levels in the hierarchy than at lower levels in the hierarchy. The effects of performance ratings on salary also differed by level. At higher levels, the impact of each increase in performance rating was greater for men than women, whereas at lower levels the impact was similar between men and women.     

Characteristics of cities that pass living wage ordinances: Are certain conditions more conducive than others?

Cities that have passed living wage ordinances often do so because of the strong political appeal of local living wage campaigns as a response to the declining value of the minimum wage, the outsourcing of municipal services, and rising income inequality. These campaigns generally consist of coalitions of community organizations, religious groups, and often times labor organizations. Organized labor is not the primary force behind most living wage campaigns, but they are an important constituency. Unexplored, however, are the labor market and other characteristics of those cities that have passed ordinances. This paper looks at data from the Current Population Survey (CPS) and compares cities that passed living wage ordinances to those that did not. Cities in states with high union density, and with higher levels of income inequality and larger immigrant populations appear to be more likely to pass living wage ordinances than those cities that do not have these demographics. But as important as union support may be, without key demographic and economic characteristics, it is nonetheless insufficient to achieve living wage ordinances in most cases.     

The difference between wages and wage potentials: Earnings disadvantages of immigrants in Germany

Immigrants in Germany have poor earnings performance relative to natives. Claiming that human-capital endowments determine earnings potentials rather than actual earnings, a stochastic earnings frontier is estimated and used to seek systematic differences between natives and migrants for GSOEP data for the year 2000. While empirical results clearly support the frontier assumption, natives and immigrants are surprisingly about the same with respect to the frontier. Assuming a half-normal distribution of the wage gap, on average, both groups transform a modest 84% share of their potential income into market earnings. This implies wage inequality can be attributed to human-capital differentials alone. The human-capital endowments of immigrants are largely determined by the very low percentage who have college degrees, their slow assimilation and zero-return on imported experience. The paper also tries to explain individual wage gaps, which are significantly decreased in married subjects raising families, but increased in employees in small- or medium-sized relative to larger firms. However, these variables only make minor contributions to the variance.     

Firm Ownership and Rent Sharing

In this paper we analyse—theoretically and empirically—how the degree of private versus public ownership of firms affects the degree of rent sharing between firms and their workers. Using a particularly rich linked employer-employee dataset from Portugal, covering a large number of corporate ownership changes across a wide spectrum of economic sectors over more than 20 years, we find that rent sharing is significantly higher in firms with a larger share of private ownership. Estimates from our most preferred empirical specification suggest that an increase in the private ownership share of 10 percentage points increases (on average) the rent-sharing elasticity by 0.0002. Based on a theoretical analysis that incorporates union-firm wage bargaining and efficiency wage effects within the same modelling framework, this result cannot be explained by private firms being more profit oriented than public ones. However, the result is consistent with a scenario whereby privatisation leads to less job security for workers, implying stronger efficiency wage effects.     

Black‐White Wage Inequality in the 1990s: a Decade of Progress

Using Current Population Survey data, we find that the gap between the wages of black and white males declined during the 1990s at a rate of about.60 percentage point per year. Wage convergence was most rapid among workers with less than 10 years of potential experience, with declines in the gap averaging 1.40 percentage points per year. Using standard decomposition methods, we find that greater occupational diversity and reductions in unobserved or residual differences are important in explaining this trend. General wage inequality tempered the rate of wage convergence between blacks and whites during the 1990s.     

Sticky floors and glass ceilings in Latin America

We employ unconditional quantile-decomposition methods to analyze the gender wage gap (gwg) in the urban region of twelve Latin American countries. Using data from harmonized household surveys we decompose the gwg into an explained component (differences in human capital) and an unexplained component (different rates of return to human capital). We find evidence of sticky floors (larger gwg at the tenth percentile than at the median) and glass ceilings (larger gwg at the ninetieth percentile than at the median). The former are more frequent and their magnitude is generally larger. Working women are more educated than working men all along the wage distribution, which partially hides the ‘unexplained’ pay difference. Finally, we find that poorer countries and countries with more income inequality have higher gwg at the tenth percentile of the wage distribution. Richer countries and countries with lower inequality present larger gwg at the ninetieth percent of the wage distribution.     

Gender inequality in wage earnings and female self-employment selection

Female self-employment has risen strongly over the last few decades and has become an important labor market development. The few studies that have examined women’s decision to become self-employed indicate that this decision is complex. Women are more likely than men to shoulder family-related obligations, especially child rearing, and there is evidence that this affects some women’s propensity to become self-employed. Also, women have yet to achieve full economic parity with men in wage employment. This paper specifically examines how gender inequality in wage earnings may precipitate some women’s selection out of wage employment and into self-employment. We find that women’s lower wage returns to observed worker characteristics have a positive and significant effect on women’s decision to switch from wage employment to self-employment.     

Can a minimum wage increase have an adverse impact on inequality? Evidence from two Latin American economies

This paper uses a semiparametric model to analyze the impact of an increase in the real minimum wage on inequality in Colombia between 1995 and 1999 and in Paraguay between 1993 and 2000–2001. Simulations suggest that if the employment effects of the minimum wage increase are ignored, the underlying policies would contribute to reduce earnings inequality in Colombia and would be inequality neutral in Paraguay. By considering the drop in wages of those who lost their jobs, simulations suggest that in both countries the policy in question would increase earnings inequality under some assumptions about the employment elasticity of the minimum wage and the new level of earnings unemployed workers rely upon. While these findings do not mean that minimum wage increases in LDCs (Less Developed Countries) necessarily have adverse distributional affects, they suggest that minimum wage policy should be implemented with care depending on how sensitive employment is to wage increases.

BB see: Transparency legislation and public discussions of wage inequality

Disparities in compensation persist between men and women. Wage transparency, which enables workers to compare their compensation to what others receive in their organization, can be an important tool for redressing specific intra‐firm disparities tied to discriminatory processes. Drawing on newspaper reports about gender pay differentials, we provide the first analysis of whether a public disclosure of pay transparency corresponds to a shift in broader public discourse, as represented by news coverage. Thematic analysis of newspaper coverage of the gender pay gap in Britain before and after the high‐profile release of BBC wage data in 2017 reveals a shift from choice‐based explanations to those emphasizing structural inequality and discrimination. The findings suggest that wage transparency coupled with news media attention may not only identify inequitable pay in firms, but also work more broadly to create space to discuss discriminatory practices and redress for pay disparities.     

Fringe Benefits and Inequality in the Labor Market

This study shows that when fringe benefits are accounted for, inequality increases at a point in time and grew faster from 1987 to 1994. Several alternative explanations of the observed discrepancies between wage inequality and compensation inequality are assessed. The evidence is that the disproportionately greater decline in income for less skilled workers is responsible for the greater decline in health insurance coverage, which in turn contributes to greater inequality growth when fringe benefits are accounted for.     

Explaining the Wage Gap: Intra-Industry Trade, Services Linkages and Falling Transportation Costs

In the debate on globalisation and wage inequality within countries, Heckscher–Ohlin theory has featured prominently, yet fails to take into account that globalisation comprises much more than increased trade between advanced and less-advanced countries. This paper develops a framework that takes better heed of the many aspects of globalisation and thereby addresses a new channel through which globalisation might influence wage inequality. Our results indicate that to understand the impact of globalisation on wage inequality, one needs insight in the nature and stage of globalisation and the relative size of a country.     

WHY DO WORKERS JOIN UNIONS? THE IMPORTANCE OF RENT SEEKING

Union status models ignore the fact that rent-seeking prospective members have an incentive to bid up entry costs so that higher union wage gains make union jobs more costly to obtain. The standard presumption that higher union wages cause firms to substitute toward higher quality workers is shown to be incorrect under most plausible assumptions; the observed positive correlation between wage gains and the propensity to join a union underestimates the size of the true supply response. The union/nonunion wage differential reveals more about the social cost of unions than the gain to an individual worker from union membership.     

Rurality and Income Inequality in the United States, 1975–2015

Recent events have focused attention on the perceived widening of the economic divide between urban and rural areas, and on the continued rise of national income inequality. We demonstrate that, in fact, the average income gap between urban (metropolitan) and rural (nonmetropolitan) households has not risen over the past 40 years, and makes virtually no contribution to national income inequality. Rising national inequality is driven by rising inequality within both urban and rural America, not by an urban/rural divergence. As is well known, the growing dispersion of household money income is partly driven by rising wage inequality, particularly in urban areas. Less well recognized is the role played by other income sources. We show that a decline in the progressivity of the distribution of social security payments and cash transfers, and an increase in the regressivity of the distribution of retirement incomes, have jointly made a comparably large contribution to rising income inequality. At the same time, the share of income from self-employment has declined, particularly in rural America, and because self-employment income is very unequally distributed, its diminution has retarded the growth of rural inequality. In 2014–15, however, rural inequality increased, cutting the urban/rural inequality gap in half.
