Income Growth and Earnings Variations in New Zealand, 1998–2004

This article analyses changes in the distributions of working‐age individuals' earnings and total income in New Zealand over the period 1998–2004. We find that there have been broad gains in income across the distribution, suggesting the spoils of growth have been shared widely. Mean and median earnings increased 15 and 23 per cent respectively, while mean and median income increased 12–13 per cent. Inequality, as measured by the Gini coefficient, was more stable: earnings inequality fell 4 per cent, while income inequality was unchanged. The main drivers of the changes were employment and real wage growth. We estimate that roughly one‐half of the growth in average incomes was due to employment growth, and one‐quarter each to demographic changes and wage growth. The relative employment and wage contributions varied across the income distribution: employment growth dominated gains at the lower end of the distribution, while wage gains dominated changes at the higher end.     

The aftermath of reunification

This article traces the evolution of the East German wage structure throughout the transition period 1992–2001. Wage dispersion has generally been rising. This increase occurred predominantly in the lower part of the wage distribution for women and in the upper part for men. Moreover, the sectoral transition affected female workers to a much larger extent than their male counterparts. A sequential decomposition analysis using quantile regressions reveals that changes in industry‐specific remuneration schemes contributed strongly to the rise in wage inequality in the lower part of the distribution for women, whereas changes in the industry composition alone would have led to a polarization of wages. In contrast, for men, changes in individual characteristics are the single most important factor contributing to the increasing wage dispersion. These gender differences are attributed to employment segregation across industries present right after German reunification.     

Wage inequality in Turkey, 2002–10

This paper studies the evolution of wage inequality in Turkey using household labour force survey data from 2002 to 2010. Between 2002 and 2004, the relative supply of more‐educated workers to less‐educated workers remained constant while their relative wages decreased in favour of less‐educated workers. However, between 2004 and 2010, the relative supply of more‐educated workers to less‐educated workers rose, while their relative wages remained constant or kept increasing in favour of more‐educated workers. This suggests factors other than those implied by a simple supply‐demand model are involved, such as skill‐biased technical change or minimum wage variations. The decomposition of wage inequality reveals that the price (wage) effect dominates the composition effect particularly in the first period. Our results show that the real minimum wage hike in 2004 corresponds to a major institutional change, which proved to be welfare‐increasing in terms of wage inequality. The upper‐tail (90/50) wage inequality decreased between 2002 and 2004 and stayed constant thereafter, whereas the lower‐tail (50/10) wage inequality decreased throughout the period. Our findings thus provide evidence supporting the institutional argument for explaining wage inequality.     

Changes in Job Structure and Rising Wage Inequality in Urban China, 1995-2007

We use household surveys from 1995, 2002, and 2007 to examine how changes in job structure contributed to China’s rising urban wage inequality, considering three job characteristics: occupation, industry, and firm ownership. The explanatory power of job structure for wage inequality increased between 1995 and 2007. Both the change in relative number of jobs (composition effect) and the change in between-job and within-job wage gaps (price effect) contributed to rising wage inequality. Price effect was the major contributor, whereas composition effect played a larger role in the 1995–2002 period than in the 2002–2007 period, and at the lower-half distribution. Between-job inequality played a major role in the first period, and within-job inequality played a major role in the second period. Our results suggest that both technological change and institutional features influence job structure and wage inequality.     

Increasing wage dispersion and the changes in relative employment and wages in Mexico's urban informal sector: 1987-1993

This study analyses the role of changes in informal/formal relative employment, wage levels and wage inequality in explaining increasing wage dispersion in Mexico during the 1987–1993 period. From 1987 to 1993, the variance of the log of hourly wages for Mexican workers increased by more than 50 per cent. Using data from the Encuesta nacional de empleo urbano we find that this increase in the overall wage dispersion was mainly driven by increasing wage dispersion in the formal sector coupled with a faster growth in formal sector employment as a percentage of total employment. However, compression in the distribution of wages within the informal sector contributed to substantially slowdown the increasing overall wage inequality. About 60 per cent of the 1987–1993 4.65 percentage point reduction in the informal sector share of total employment is explained by changes in the structure that determines sectoral employment; the rest is explained by changes in the composition of the labour force, particularly increases in the sectoral education gap and a change in the regional relative share of sectoral employment. Also, from 1987 to 1993 the sectoral wage ratio increased from 0.59 to 0.63. It seems that a relative improvement in unobserved skills in the informal sector helped to close the wage differential but this effect was partially offset by an increase in the relative prices of both observed and unobserved skills, as well as increases in relative observed skills in the formal sector, particularly education.     

Employment fluctuations and dynamics of the aggregate average wage in Poland, 1996–20031

The aggregate average wage is often used as an indicator of economic performance and welfare, and as such often serves as a benchmark for changes in the generosity of public transfers and for wage negotiations. Yet if economies experience a high degree of (non‐random) fluctuation in employment, the composition of the employed population will have a considerable effect on the computed average. In this paper we demonstrate the extent of this problem using data for Poland for the period 1996–2003. During these years the employment rate in Poland fell from 51.2 percent to 44.2 percent and most of this fall occurred between the end of 1998 and the end of 2002. We show that about a quarter of the growth in the average wage during this period could be attributed purely to changes in employment.     

Earning functions in Portugal 1982–1994: Evidence from quantile regressions

This paper uses quantile regressions to describe the conditional wage distribution in Portugal and its evolution over the 1980s as well as the implications for increased wage inequality. We find that, although returns to schooling are positive at all quantiles, education is relatively more valued for highly paid jobs. Consequently, schooling has a positive impact on wage inequality. Moreover, this tendency has sharpened over the period. We also find that most of the estimated change in wage inequality was due to changes in the distribution of the worker's attributes, rather than to increased inequality within a particular type of worker. this version: January 2000     

The North Will Rise Again: Pensions,Politics and Power in the 1980’s

I aim at contributing to the academic debate about the relationship between functional income distribution and economic growth in regard to the large and open economy of Turkey in the period from 1987 to 2006. To this end, I propose a simple post-Keynesian model, so as to test whether the Turkish economy is wage or profit-led. I find evidence that, while a rising wage has a positive effect on investment, it does not affect consumption in Turkey. Hence the combined effect of a rising wage share on domestic demand (investment plus consumption) is positive. However, since exports and imports are so sensitive to labor costs, as they are in the case of Turkey, the regime becomes profit-led.     

A contribution to the public–private wage inequality debate

This paper studies the public–private wage inequality in Romania. Although public sector employment is perceived as safer and offering more benefits, we find that in Romania it also offers higher wages, after controlling for experience, education and gender. This result is at odds with the negative premium uncovered in other transition economies. The public–private wage premium is increasing across the wage distribution, leading to more inequality in the public sector. Decomposing the wage premium into the effect of personal characteristics, coefficients and residuals, we show that only about half of this premium can be attributed to personal characteristics, especially in the top half of the wage distribution. We also find that the number of other public sector employees in the family is a significant driver of public sector employment, facilitating access to jobs. However, the effects of self‐selection are negligible, the premium being still positive and significant after controlling for this.     

Wage Growth Distribution and Changes over Time: 2001–2018

We explore how much wage growth varies among Australian employees and how it has changed over the 2001–2018 period. The results show that, after increasing between 2002 and 2007, wage growth significantly slowed post 2008, and particularly from 2013 onwards, returning to early 2000s levels. Employee age, education, employment contract, occupation and industry explain a large share of differences in wage growth between individuals. Employee occupation is more important post‐2008 than pre‐2008, whereas education is more important pre‐2008. Finally, casual employees receive a wage growth premium during periods of economic upturn and a penalty during downturn.     

Increased sorting and wage inequality in the Czech Republic

This paper makes use of a linked employer–employee dataset to examine the evolution of wage inequality in the Czech Republic during 1998–2006. We find evidence of slightly increasing returns to human capital and diminishing gender inequality and document sharp increases in both within‐firm and between‐firm inequality. We investigate several hypotheses to explain these patterns: increased domestic and international competition, decentralized wage bargaining, skill‐biased technological change and a changing educational composition of the workforce. Domestic competition is found to lower within‐firm inequality whereas we find no evidence that increased international trade at the industry level is associated with higher between‐ or within‐firm wage inequality. The key factors driving the observed increase in wage inequality are increased educational sorting and the inflow of foreign firms to the Czech Republic.     

Informal Employment and the Structure of Wages in India: A Review of Trends

The “alternative”, “atypical” or “informal” workforce has grown in developed and developing countries alike. One of the more recent evolutions of informal employment has been of informal employment within formal enterprises. In the interest of flexibility and cost‐reduction, many formal firms increasingly resort to hiring workers on a temporary or informal basis. Alongside, and perhaps, as a result of the persistence and pervasiveness of informal employment, issues relating to inequality have come to the fore. This paper is motivated by these two intertwining aspects of Indian labor market—informality and wage inequality. Using nationally representative sample data, the paper examines trends in wage inequality among various forms of informal workers, overlaying these findings with broader trends in inequality. Using a regression based inequality decomposition, the paper compares the sources of wage inequality across different employment groups and the reasons for differences in wage inequality.     

Why Did Income Inequality in Germany Not Increase Further After 2005?

While income inequality in Germany considerably increased in the years before 2005, this trend stopped after 2005. We address the question of what factors were responsible for the break in the inequality trend after 2005. Our analysis suggests that income inequality in Germany did not continue to rise after 2005 for the following reasons. First, we observe that the general rise in wage inequality that explained a lot of the inequality increase before 2005, became less steep (but did not stop) after 2005. Second, despite further increases in wage inequality after 2005, inequality in annual labour incomes did not increase further after 2005 because increased within‐year employment opportunities compensated otherwise rising inequality in annual labour incomes. Third, income inequality did not fall in a more marked way after 2005 because also the middle and the upper part of the distribution benefited from the employment boom after 2006. Finally, we provide evidence that the effect of a wide range of other factors that are often suspected to have influenced the distribution such as capital incomes, household structures, population ageing, changes in the tax and transfer system and the financial crisis of 2008 did not significantly alter the distribution after 2005.     

Wage Inequality and Wage Mobility in Europe

Using data from the European Union Statistics on Income and Living Conditions, this paper investigates wage inequality and wage mobility in Europe. Decomposing inequality into within‐ and between‐group inequality, we analyze to what extent wage inequality and mobility can be explained by observable characteristics. Furthermore, we investigate which individual and household characteristics determine transitions within the wage distribution. We find that overall, mobility reduces wage inequality. While a large part of wage inequality is due to unobservable characteristics, the equalizing effect of mobility mainly occurs within groups. Furthermore, both personal and household characteristics play an important role for wage transitions. Finally, our findings reveal large cross‐country differences across Europe.     

THE GROWTH OF FAMILY EARNINGS INEQUALITY IN CANADA, 1980–2005

In this study we document recent trends in family earnings inequality using data from the Canadian Census and provide insight into the various factors that drive changes in the family earnings distribution. Over the period 1980–95 we observe substantial increases in family earnings inequality. In contrast, we find that some decrease in inequality occurred over the period 1995–2005 although the earnings of the richest 1 percent of families increased substantially. We use semi‐parametric decomposition methods to show that increases in the employment rates of men and women, increases in their educational attainment, and decreases in assortative mating tended to have equalizing effects on the family earnings distribution. We also show that increases in the returns to higher education and increases in the proportion of single individuals as well as lone‐parent families drove increases in family earnings inequality.     

INEQUALITY OF WAGE RATES,EARNINGS AND FAMILY INCOME IN THE UNITED STATES, 1975–2002

This paper analyzes distributional changes over the last quarter of the twentieth century. We focus on four distinct distributions: the distribution of hourly wage rates, the distribution of annual earnings of individuals, the distribution of annual earnings of families, and the distribution of total family income adjusted for family size. Both male wage rate inequality and family income inequality accelerated during the early 1980s, increased at a slower rate through the early 1990s and then stabilized at a high level through the early 2000s. The similarity in the timing of changes in these two distributions has been used as evidence that increased family income inequality primarily reflects increased inequality of wage rates. We show that other important factors were also at work.     

Does Raising the Minimum Wage Help the Poor?*

What is the impact of raising the minimum wage on family incomes? Using data from the 1994–1995 to 2002–2003 Survey of Income and Housing, the characteristics of low-wage workers are analysed. Those who earn near-minimum wages are disproportionately female, unmarried and young, without postschool qualifications and overseas born. About one-third of near-minimum-wage workers are the sole worker in their household. Due to low labour force participation rates in the poorest households, minimum-wage workers are most likely to be in middle-income households. Under plausible parameters for the effect of minimum wages on hourly wages and employment, it appears unlikely that raising the minimum wage will significantly lower family income inequality.     

HOUSEHOLD INEQUALITY AND THE LABOR MARKET IN SOUTH AFRICA

There has been very little detailed exploration of the relationship between wage income and household inequality in South Africa despite the relevance of this issue for many contemporary growth and development policy debates. This article is directed at such an analysis. It uses a decomposition of household income inequality by income components to highlight the dominance of wage income in driving overall income inequality. This is followed by a detailed discussion of the distribution of the unemployed across different wage-earning household categories. Many of the unemployed are seen to depend on wage earners within their households, but a significant percentage of the unemployed, especially in rural areas, have no direct link to labor market earners. In such cases, the creation of employment is essential. The conclusion explores policy implications by linking our empirical findings to South African debates over the quality versus the quantity of employment.     

Explaining the increase in inequality during transition

This paper attempts to explain the increase in inequality that has been observed in all transition economies by constructing a simple model of change in composition of employment during the transition. The change consists of the 'hollowing-out' of the state-sector middle class as it moves into either the 'rich' private sector or the 'poor' unemployed sector. The predictions of the model are contrasted with the empirical evidence from annual household income surveys from six transition economies (Bulgaria, Hungary, Latvia, Poland, Russia and Slovenia) over the period 1987-95. We find that the most important factor driving overall inequality upwards was increased inequality of wage distribution. The non-wage private sector contributed strongly to inequality only in Latvia and Russia. Pensions, paradoxically, also pushed inequality up in Central Europe, while non-pension social transfers were too small everywhere and too poorly focussed to make much difference.     

Public–private wage differentials in Turkey: public policy or market dynamics?

We evaluate public–private sector wage differentials by gender in Turkey between the years 2005 and 2013. Using micro data from Household Labor Force Surveys we find a positive premium for low wage earners and a penalty of working in the public sector at the higher end of the distribution. Although the penalty has not disappeared, the price effect has increased at both ends of the distribution. The increase at the lower tail is attributed to a higher price effect in the public sector, whereas at the higher tail it has been a result of a relatively uneven wage increase in the private sector along the distribution, rather than an explicit public wage policy.
