Rising wage inequality,the decline of collective bargaining,and the gender wage gap

This paper investigates the increase in wage inequality, the decline in collective bargaining, and the evolution of the gender wage gap in West Germany between 2001 and 2006. Based on detailed linked employer–employee data, we show that wage inequality is rising strongly — driven not only by real wage increases at the top of the wage distribution, but also by real wage losses below the median. Coverage by collective wage bargaining plummets by 16.5 (19.1) percentage points for male (female) employees. Despite these changes, the gender wage gap remains almost constant, with some small gains for women at the bottom and at the top of the wage distribution. A sequential decomposition analysis using quantile regression shows that all workplace related effects (firm effects and bargaining effects) and coefficients for personal characteristics contribute strongly to the rise in wage inequality. Among these, the firm coefficients effect dominates, which is almost exclusively driven by wage differences within and between different industries. Labor demand or firm wage policy related effects contribute to an increase in the gender wage gap. Personal characteristics tend to reduce wage inequality for both males and females, as well as the gender wage gap.     

A SURVEY OF TRADE AND WAGE INEQUALITY: ANOMALIES,RESOLUTIONS AND NEW TRENDS

This paper surveys recent studies on trade and wage inequality. We first introduce some trade‐based explanations for increased wage inequality. There are, however, a number of criticisms of this line of thought based on the ‘trade‐wage inequality anomaly’, the ‘price‐wage anomaly’, and the small volume of trade. Mainly due to these criticisms, trade‐based explanations for rising wage inequality have been limited in the economic literature. Rather, the primary explanations for wage inequality have been based on skill‐biased technological change. Some trade models, however, have weakened the above criticisms, and more economists now argue that the effect of trade, though relatively small compared to that of technological change, is more significant than generally believed. Finally, we attempt to link new trends in inequality, such as job polarization and within‐group inequality, to the trade and wage inequality literature.     

A spatial analysis of inward FDI and urban–rural wage inequality in China

This article investigates the spatial effect of inward foreign direct investment (FDI) on urban–rural wage inequality, both in the short and long run, by employing the Spatial Durbin Model. In particular, we carefully consider the heterogeneity of inward FDI with respect to its entry mode (ownership type) and sectoral distribution. Based on a panel dataset covering 30 provinces and cities in China from 2000 to 2016, our results show that inward FDI does not increase urban–rural wage inequality. In particular, we do not find a significant relationship between inward FDI in the secondary and tertiary sectors, while inward FDI in the primary sector has a slightly negative effect on inequality. When we consider inward FDI by entry mode, we find that wholly foreign-owned enterprises (WFE) have a negative spatial effect on urban–rural wage inequality in the short and long run, while equity joint ventures (EJV) reduce urban–rural inequality in the long run only.     

Wage inequality and the role of multinationals: evidence from UK panel data

Despite the increased attention on the impacts of globalisation, there has been little empirical investigation into the impact of multinational firms on the domestic labour market and in particular wage inequality, this is in spite of a rapid increase in foreign direct investment (FDI) at around the same time of rising inequality. Using UK panel data, this paper tests whether inward flows of FDI have contributed to increasing wage inequality. Even after controlling for the two most common explanations of wage inequality, technology and trade, we find that FDI has a significant effect upon wage inequality, with the overall impact of FDI explaining on average 11% of wage inequality.     

Winners and losers after 25 years of transition: Decreasing wage inequality in Slovenia

Over the past twenty-five years, wage inequality has fallen in Slovenia, even as it has risen in most developed economies. The rates of return to education and work experience rose and remained high on average. However, rapid increases in the number of college graduates have outpaced the rising relative demand for skill among the youngest labor market entrants. As a result, the youngest cohorts of college graduates have experienced declining returns to education and a downward shift in their occupational distribution, which has not been experienced by older college graduates. These changes coincide with the implementation of the Bologna Reform, which reduced the length of time necessary to complete a bachelor’s degree and contributed to the incentives to attend college. Falling returns to tertiary education contributed to declining within-cohort wage inequality among the young, which was large enough to reduce overall wage inequality.     

Spatial changes in labour market inequality

We study spatial changes in labour market inequality for US states and MSAs using Census and American Community Survey data between 1980 and 2010. We report evidence of significant spatial variations in education employment shares and in the college wage premium for US states and MSAs, and show that the pattern of shifts through time has resulted in increased spatial inequality. Because relative supply of college versus high school educated workers has risen faster at the spatial level in places with higher initial supply levels, we also report a strong persistence and increased inequality of spatial relative demand. Bigger relative demand increases are observed in more technologically advanced states that have experienced faster increases in R&D and computer usage, and in states where union decline has been fastest. Finally, we show the increased concentration of more educated workers into particular spatial locations and rising spatial wage inequality are important features of labour market polarization, as they have resulted in faster employment growth in high skill occupations, but also in a higher demand for low wage workers in low skill occupations. Overall, our spatial analysis complements research findings from labour economics on wage inequality trends and from urban economics on agglomeration effects connected to education and technology.

Is there a compensating wage differential for high crime levels? First evidence from Europe

This paper investigates whether high regional crime levels lead to a compensating wage differential paid by firms in the respective region. Using data from German social-security records, official police statistics and official statistics for 2003–2006, I consider both violent and non-violent crimes and use three-way error-components estimators to control for individual and regional heterogeneity. The findings suggest that wages are practically unrelated to changes in crime rates. This result is robust over a wide range of subgroups. There is, however, some evidence that crime rates influence land prices.     

Wage inequality, technology and trade: 21st century evidence

This paper describes and explains some of the principal trends in the wage and skill distribution in recent decades. Increases in wage inequality started in the US and UK at the end of the 1970s, but are now widespread. A good fraction of this inequality trend is due to technology-related increases in the demand for skilled workers outstripping the growth of their supply. Since the early 1990s, labor markets have become more polarized with jobs in the middle third of the wage distribution shrinking and those in the bottom and top third rising. I argue that this is because computerization complements the most skilled tasks, but substitutes for routine tasks performed by middle wage occupations such as clerks, leaving the demand for the lowest skilled service tasks largely unaffected. Finally, I argue that technology is partly endogenous, for example it has been spurred by trade with China. Thus, trade does matter for changes in the labor market, but through a different mechanism than conventionally thought.     

Permanent and transitory wages of British men, 1975–2001: year,age and cohort effects

We examine the mean and variance–covariance structure of log-wages over calendar time and the life cycle of British men, hereby controlling for birth cohort effects. We attribute the strong increase in mean log-wage during the 1980s and 1990s to a rise in mean log-wage with the year of birth. This rise is diminishing with the year of birth, which implies lower wage inequality between cohorts with the year of birth. Wage inequality has increased during the 1980s and early 1990s and remained fairly stable in the second half of the 1990s. The year effects, however, show increasing wage inequality up to 2001, mainly due to a strong rise in transitory wage inequality. Transitory wages are strongly correlated over time and an increase in transitory wage inequality therefore has highly persistent inequality consequences. The stable wage inequality in the second half of the 1990s is attributed to lower within-cohort wage inequality for the younger cohorts. The age effects show that permanent wage inequality increases with age, in particular up to age 30 and over age 50. Copyright © 2007 John Wiley & Sons, Ltd.     

Within Occupation Wage Dispersion and the Task Content of Jobs

Most analyses linking task content of jobs to income inequality focus on the effects between occupations, e.g. the growing dispersion between lousy and lovely jobs. The theory, meanwhile, provides insights on links between task content of jobs and inequality also within occupations: models predict compression of wages in more routine jobs, that is those where capital is a direct substitute for labour, and an increase in dispersion in jobs where capital and labour are complements. I document that within occupations dispersion of wages is empirically relevant, as it represents around half of total wage inequality across Europe. I then link wage inequality to the task content of jobs. Using matched employee–employer data from Europe for the period 2002–14, I show that occupations where tasks complement newer technologies exhibit higher wage dispersion. This relationship is robust to adjusting for a variety of confounding and mitigating channels.     

Monopsonistic discrimination, worker turnover, and the gender wage gap

Motivated by models of worker flows, we argue in this paper that monopsonistic discrimination may be a substantial factor behind the overall gender wage gap. Using matched employer–employee data from Norway, we estimate establishment-specific wage premiums separately for men and women, conditioning on fixed individual effects. Regressions of worker turnover on the wage premium identify less wage elastic labour supply facing each establishment of women than that of men. Workforce gender composition is strongly related to employers' wage policies. The results suggest that 70–90% of the gender wage gap for low-educated workers may be attributed to differences in labour market frictions between men and women, while the similar figures for high-educated workers ranges from 20 to 70%.     

Men's wage inequality in Serbia's transition

Wage inequality is considered to have been quite compressed in socialist economies. In this paper I analyse how men's wage inequality has changed during the period of transition to a market economy in Serbia, a country which has experienced a particularly dramatic transition. Changes in the distribution of earnings are examined using the Lemieux (2002) decomposition methodology and five annual Labour Force Surveys (2001–2005). I find that the change in wage inequality is mostly driven by changes in wage premiums, while the effect of changes in the composition of the labour force is very small. Isolating the effect of the emerging private sector reveals that changes in the private sector size and wage premium account for an average 25 per cent of the changes in inequality during this period. Moreover, the minimum wage is found to exert a dampening effect on wage inequality.     

Earnings inequality narrows for young workers despite a widening wage structure

Inequality of wage rates has widened in the United States. But inequality of earnings also depends on the distribution of hour's worked. If the distribution of hours contracts sufficiently, earnings inequality may narrow despite a widening wage structure. The present study examines recent trends in inequality for young workers and, consistent with the preceding scenario, finds that rising inequality of wage rates has been overwhelmed by declining inequality of hours worked. As a consequence, earnings inequality of young workers declined during the 1980s.     

Marginal effects of public employment on unconditional distribution of wage income in China

This paper examines the marginal effects of an employment expansion in China’s public sector on the unconditional distribution of “wage income” using the unconditional quantile estimation suggested by Firpo et al. (2009). Empirical data from the China Health and Nutrition Survey is split into three sub-samples to eliminate the effects of the Asian financial crisis in 1997 and the subprime financial crisis in 2008 on our empirical results. To explore the marginal effects, the empirical unconditional distributions of wage income “before” and “after” an expansion of the public employment have been graphed and compared. It has been found that an expansion of China’s public employment reduces the dispersion of wage income and hence alleviates income inequality in China. Besides, an expansion of public employment makes the symmetrical unconditional distribution of wage income become leftward skewed. Given these findings, an expansion of the public employment caused by the strategy of “guojin mintui” could mitigate China’s income inequality.     

NOMINAL AND REAL WAGE RIGIDITIES IN NEW KEYNESIAN MODELS: A CRITICAL SURVEY

Abstract The labour market is receiving increasing attention in the New Keynesian literature. In this paper, I critically survey this literature in order to highlight the role played by wage rigidities in the explanation of fluctuations caused by technology shocks. To this aim, I present a dynamic stochastic general equilibrium model with sticky prices, nominal wage rigidities and hiring costs. The comparison between this model and that of Blanchard and Gali highlights the non‐trivial differences which exist in the way nominal wage and real wage rigidities drive the economy's dynamics. My conclusion is that models incorporating nominal wage rigidities and some degree of price stickiness provide a better account of macroeconomic dynamics than models with real wage rigidities.     

Regional Wage Gaps,Education and Informality in an Emerging Country: The Case of Colombia

This paper uses Colombian micro-data to analyze the role of education and informality in regional wage differentials. The hypothesis is that apart from differences in the endowment of human capital, regional heterogeneity in the incidence of informality is another important source of regional wage inequality in emerging countries. This is confirmed by the evidence from Colombia, which also reveals remarkable spatial heterogeneity in the wage return to individuals’ characteristics. Regional heterogeneity in returns to education is especially intense in the upper part of the wage distribution. In turn, heterogeneity in the informal pay penalty is more relevant at the bottom.     

Skill supply and biased technical change

This article contributes to the debate on skill-biased technical change by studying the dynamics of skill supply and wage inequality in an endogenous growth model with ability-biased technical progress. Due to a discouragement effect, rising within groups inequality reduces incentives to become educated for ordinary-ability workers. This mechanism generates a non-monotonic relationship between the growth rate and skill supply driving wage inequality upward during periods of accelerating technical change. This theoretical explanation is consistent with the apparent ambiguous relationship between the relative skill supply and inequality in the last decades in several OECD countries.     

The wage policy of firms: comparative evidence for the US and Germany from personnel data

The wage policy of a German firm and a US firm is subjected to a comparative analysis, focusing on the relation between wages and hierarchies. While previous studies have examined only one particular firm, this paper investigates two plants belonging to the same owners with similar production processes but in different institutional environments. Convex wage profiles over the hierarchy levels of both plants are found. The US plant shows considerably higher intensity of intra-firm competition in terms of higher intra-level wage inequality and annual promotion rate. In contrast, wages are more distinctly attached to hierarchy levels in the German firm, as shown by wage regressions. The results are discussed in relation to previous studies.
