The purpose of this paper is to examine the wage differentials along the entire distribution between immigrants and the Australian-born.

Using the Household, Income and Labour Dynamics in Australia (HILDA) Survey, the authors apply a semi-parametric method (DiNardo et al., 1996) to decompose the distributional wage gap between immigrants and native-born Australians into composition effect and wage structure effect. The authors further apply the unconditional quantile regression (UQR) method (Firpo et al., 2007) to decompose the overall wage structure effect into contributions from individual wage covariates.

Relative to the native-born, both effects favour immigrants from English-speaking countries. For male immigrants from non-English-speaking countries (NESC) the favourable composition effect is offset by disadvantage in the wage structure effect, leaving little overall wage difference. Female immigrants from NESC are disadvantaged at the lower part of the wage distribution.

The increasingly skill-based immigration policy in Australia has increased skill levels of immigrants relative to the Australian-born. However, the playing field may yet to be equal for the recent NESC immigrants due to unfavourable rewards to their productivity factors. Also, immigrants are not homogeneous. Countries of origin and gender matter in affecting wage outcomes.

The unique wage-setting system and the increasingly skill-based immigration policy have made Australia an interesting case. The authors examine the entire wage distribution between migrants and native-born rather than focus on the mean. The authors differentiate immigrants by their country of origin and gender; and apply the UQR decomposition to identify the contributions from individual wage covariates.

Between 1995 and 2012, the wage distribution of male workers in Brazil shifted to the right and became less dispersed. This paper attempts to identify the reasons for that movement in male wage distribution, focusing on the impact of education expansion on wage distribution. The Oaxaca-Blinder (OB) and Recentered Influence Function (RIF) decomposition results show that both changes in returns on skills and upgrades in the composition of work skills contribute to increases in the average wage and wages at the 10th and 50th percentiles. The shifts in returns to skills had a decreasing impact on wages at the 90th percentile and are identified as the primary force reducing wage inequality. Education expansion had an equalizing impact on wage distribution, primarily through the decline in return to education.

This study aims to analyse the contribution of the expansion and diversification of higher education to Chile's increase in wage inequality from 1992 to 2000 and its subsequent decrease from 2000 to 2013.

The wage equation for each year is estimated using data from the national household survey, Encuesta de Caracterización Socioeconómica Nacional (CASEN). Using the method proposed by Firpo et al. (2009), the evolution of wage changes is decomposed into composition and wage structure effects of each explanatory variable at different points of the wage distribution.

The results show that the positive composition effect of higher education, derived from the increasing share of both workers with university degrees and those with vocational degrees, is substantially larger at the upper quantiles and exceeds the negative wage structure effect, thereby contributing to increasing wage inequality from 1992 to 2000. By contrast, the negative wage structure effect of higher education, primarily derived from the decreasing return to university degrees, is substantially larger at the upper quantiles and exceeds the positive composition effect, thereby contributing to decreasing wage inequality from 2000 to 2013.

This study contributes to the literature by showing that the expansion of higher education increased inequality in the 1990s and decreased it in the 2000s while the increasing supply of workers with vocational degrees decreased wage premiums for university degrees in the latter period.

This study investigated the gender wage gap in Nigeria by analysing two waves of household surveys (in 2003–2004 and 2018–2019) in order to understand the dynamics or polarisation of the labour market in Nigeria in terms of the gender wage gap over time.

The study applied an extension of Oaxaca–Blinder decomposition that relies on the re-centred influence function (RIF) regressions to analyse the gender wage gap at all points along the wage distribution.

The results unambiguously show that there is a significant gender wage gap in Nigeria at all points along the wage distribution, such that for the two surveys used and after nearly two decades, men still earn more than women. That is, the log wage difference between males and females is statistically significant at all points between the 10th and the 90th quantiles. In 2003–2004 period, the authors found that most of the wage difference was significantly accounted for by the wage structure effect, whilst the composition effect was negative and only significant at the bottom of the wage distribution. Since the 2018–2019 period, the authors found that there has been a visible change such that most of the gender wage gap is now accounted for by the composition effect at all points along the wage distribution. Another interesting finding is that there has been a general decline in the gender wage gap along the entire wage distribution, such that inequality was higher in 2003–2004 than in 2018–2019. This decline is bigger at the top than at the bottom of the wage distribution. The authors also found that, contrary to some of the studies on the wage gap, the raw gaps for the two surveys appear to show inverted U-shape, but the gap has fallen quickly since the 2018–2019 period. Thus, the authors found strong evidence of a “sticky floor” compared to a “glass ceiling” effect in both periods, and this becomes more pronounced over time. In terms of the contributions of individual covariates on gender pay gap in Nigeria, the authors found that urban residence, unionisation, education and occupation variables exhibit major influence. However, the effects of covariates on the composition and wage structure components of the wage gap have changed over time.

The major policy implication of these findings is that to address the gender wage gap in Nigeria, policy should focus more on how labour is rewarded and improving human capital for women.

This study is a novel paper in Nigeria that has investigated the gender wage gap in Nigeria by extending the focus of literature in three ways. First, the authors applied an extension of Oaxaca–Blinder decomposition that relies on the RIF regressions to analyse the gender wage gap at all points along the wage distribution. Second, the authors used sample selection bias to account for the non-randomness of participation in wage employment. And third, the authors applied similar analysis to two waves of household surveys (in 2003/2004 and 2018/2019) in order to understand the dynamics or polarisation of the labour market in Nigeria in terms of the gender wage gap over time.

This paper examines the level and structure of the wage inequality between nonrefugee and refugee workers in Palestine and the extent to which such wage gap reflects any marginalization and discrimination against refugees. It also investigates how the disparities in distribution to individual worker characteristics contribute to the wage inequality in Palestine.

The authors use both Oaxaca and Blinder (OB) (Oaxaca, 1973 and Blinder, 1973) and Fortin et al. (2011) unconditional quantile decomposition approaches to measure the size of the wage gap along with the wage distribution and to decompose the wage differences into productivity (i.e. explained or the composition effects) and wage structure effects (i.e. unexplained or discrimination effects).

Results indicate that most of the wage gap between refugees and nonrefugees is attributed to the wage structure effect (possibly explained by discrimination) against refugees in the Palestinian labor market. The wage gap between refugees and nonrefugees is not uniform throughout the wage distribution and supports the “sticky floor effect.”

This work introduces important policy implications for the policymakers in the Palestinian labor market. It reveals the economic and social factors, individual worker characteristics as well as labor market characteristics contribute to the wage inequality in Palestine.

This research reveals a crucial social challenge in the Palestinian society, represented by the wage discrimination against refugees in Palestine. This is despite the denial of such discrimination from official bodies, local institutions and many other policymakers. It also captures gender inequality between men and women.

This is the first empirical work in Palestine that contends with a very sensitive issue in the Palestinian society, that is, the discrimination against refugees in the Palestinian labor market. Most of the existing studies have approached this issue from a humanitarian view in order to show the deterioration of social and economic situations in the refugee camps.

We examine the cardinal gap between wage distributions of the incumbents and newly hired workers based on entropic distances which are well-defined welfare theoretic measures. Decomposition of several effects is achieved by identifying several counterfactual distributions of different groups. These go beyond the usual Oaxaca–Blinder decompositions at the (linear) conditional means. Much like quantiles, these entropic distances are well-defined inferential objects and functions whose statistical properties have recently been developed. Going beyond these strong rankings and distances, we consider weak uniform ranking of these wage outcomes based on statistical tests for stochastic dominance. The empirical analysis is focused on employees with at least 35 hours of work in the 1996–2012 monthly Current Population Survey (CPS). Among others, we find incumbent workers enjoy a better distribution of wages, but the attribution of the gap to wage inequality and human capital characteristics varies between quantiles. For instance, highly paid new workers are mainly due to human capital components, and in some years, even better wage structure.

This paper examines the role of occupational segregation in the evolution of wage differentials by gender and race in the Brazilian labor market between 2005 and 2015.

The author uses microdata from the National Household Sample Survey and adopts two occupational integration typology to capture both horizontal and vertical segregation. The decomposition method proposed by Firpo et al. (2009) is employed to investigate the determinants of changes in differentials along the wage distribution.

Results suggest a glass ceiling effect for all groups compared to white men. Gender and racial discrimination persist, especially at the top of the distribution. For both black women and men, observable characteristics account for most of the wage differentials, while for white women, the opposite occurs because of their education level. Vertical segregation behavior indicates that white men continue over-represented in higher-paid occupations. Although women improved their relative position in the occupational hierarchy, horizontal segregation behavior shows that their concentration in female-dominated occupations has not reduced, except in extreme quantiles. Education played a crucial role in reducing wage gaps, and regional differences stood out as a significant factor of the racial disadvantage.

The paper shows significant differences between the groups regarding verticalization and horizontalization of occupational structure along the wage distribution and over time, contributing to filling some gaps in the literature concerning the wage stratification based on gender and race in Brazil. Occupational segregation as a composition factor of the groups determines their positions in a vertically hierarchical and socially stratified occupational structure. The behavior of horizontal and vertical segregations evidences the continue under-valorization of female occupations and the barriers faced by racial and gendered groups to overcome the glass ceiling effect. Recognize the intersectionality of gender and race in addressing inequalities is fundamental to promote policies that overcome them.

Relies on cross‐sectional survey data from 1986 and 1993 to explain an increase in the ethnic Turk‐ethnic Bulgarian earnings differential in Bulgaria in the country’s early transition. Empirical evidence indicates that the ethnic Turks closed both the gap in the number of years of education and experience acquired during this time. Further, the Turks began to enter the growing commerce and transportation industries in the early transition. Shifts in the wage structure, however, favored the ethnic Bulgarians, and these changes outweighed ethnic Turk gains in the measured characteristics. In addition to these shifts, an increase in the overall level of inequality in the labor market punished those at the low‐end of the wage distribution, exacerbating the existing ethnic earnings differential. These results imply however, that the ethnic Turks are responding to market signals and if it continues, this trend will diminish the ethnic earnings gap.

We examine the potential effect of naturalization on the U.S. immigrants’ earnings. We find the earning gap between naturalized citizens and noncitizens is positive over many years, with a tent shape across the wage distribution. We focus on a normalized metric entropy measure of the gap between distributions, and compare with conventional measures at the mean, median, and other quantiles. In addition, naturalized citizen earnings (at least) second-order stochastically dominate noncitizen earnings in many of the recent years. We construct two counterfactual distributions to further examine the potential sources of the earning gap, the “wage structure” effect and the “composition” effect. Both of these sources contribute to the gap, but the composition effect, while diminishing somewhat after 2005, accounts for about 3/4 of the gap. The unconditional quantile regression (based on the Recentered Influence Function), and conditional quantile regressions confirm that naturalized citizens have generally higher wages, although the gap varies for different income groups, and has a tent shape in many years.

The purpose of this paper is to document the wage effects associated with sexual orientation and to examine whether the wage gap has improved following recent institutional changes which favour sexual minorities.

Ordinary least squares and quantile regressions are estimated using Australian data for 2010–2012 and 2015–2017, with the analysis disaggregated by sector of employment. Blinder–Oaxaca decompositions are used to quantify unexplained wage gaps.

Relative to heterosexual men, in 2015–2017 gay men in the public and private sectors had wages which were equivalent to heterosexual men at all points in the wage distribution. In the private sector: highly skilled lesbians experienced a wage penalty of 13 per cent; low-skilled bisexual women faced a penalty of 11 per cent, as did bisexual men at the median (8 per cent penalty). In the public sector low-skilled lesbians and low-skilled bisexual women significant experienced wage premiums. Between 2010–2012 and 2015–2017 the pay position of highly skilled gay men has significantly improved with the convergence driven by favourable wage (rather than composition) effects.

The results provide important benchmarks against which the treatment of sexual minorities may be monitored.

The analysis of the sexual minority wage gaps by sector and position on the wage distribution and insight into the effect of institutions on the wages of sexual minorities.
