Differential rewards to, and contributions of, education in urban China's segmented labor markets

Abstract. Using worker data from a 1999–2000 urban enterprise survey, we examine the effects of education on the current earnings of continuously employed urban workers, migrants and laid off but subsequently re‐employed workers. We also decompose the earnings differentials between each of these groups of workers and then assess the contribution of education to explanations of the differentials. The empirical results demonstrate that returns to education increase with marketization and competition in the workplace. We also find educational attainment to be an important explanator of the earnings differentials between institutionally differentiated groups of workers in China's urban labor markets.     

Earnings Inequality in Australia: Changes, Causes and Consequences

This article reviews research on recent developments in earnings inequality in Australia. Four main issues are addressed. First, what are the main changes in earnings inequality which have occurred? Second, what do we know about the causes of changes in earnings inequality? Third, how have earnings differentials between workers in different skills groups changed, and to what extent can those changes be explained by shifts in the relative demand for labour and relative supply of labour by level of skill? Fourth, how have changes in earnings inequality affected the distribution of income?     

Fields of Study and the Earnings Gap by Race in Brazil

Workers with tertiary education in Brazil earn three times more than those with a lower level of schooling. Thus, the attainment of a bachelor's or graduate degree by a black worker usually provides important benefits at the individual level. However, an educational improvement of this type does not assure equal labor market outcomes relative to white workers with the same level of education. The labor earnings differential by race in Brazil is high even among individuals who completed at least a bachelor's degree. This paper investigates this labor earnings gap, emphasizing the unequal distribution of whites and blacks across fields of study. Evidence indicates that disparities in the distribution of racial groups across fields of study help explain 18% of the total median earnings differential in 2000 and 33% in 2010, accounting for most of the gap between white and black workers due to characteristic effects in this latter period.     

Increasing dispersion of skills and rising earnings inequality

In recent decades many countries have simultaneously liberalized their trading regimes and expanded their education systems. The theoretical effect of these regime shifts on the wage differential between skilled and unskilled workers is ambiguous. On the one hand, openness to trade causes demand shifts in the labor market which may widen or narrow the differential. This result depends on whether the unskilled wage is depressed, as in the case of importing countries, or raised, as in the case of exporting countries. On the other hand, an increased supply of more educated workers reduces their wages and narrows the skill wage gap. In this study of the labor market of Hong Kong, we document that recent changes in response to the trade liberalization of Mainland China and expanded access to education have increased the earnings differential between skilled and unskilled workers. Using detailed census data, we argue that the main reason for this outcome is the widened dispersion of skills across the earnings distribution, resulting from demand and supply shifts in the labor market caused by trade openness and expanded access to higher education.     

LONG‐RUN INEQUALITY AND SHORT‐RUN INSTABILITY OF MEN'S AND WOMEN'S EARNINGS IN CANADA

This paper examines the variability of workers’ earnings in Canada over the period 1982–2006. We decompose the total variance of workers’ earnings into a ‘permanent’ component between workers and a ‘transitory’ earnings instability component over time for given workers. We then investigate the statistical relationships between these components and indicators for the business cycle. The most marked change in earnings variances in Canada since 1982 is the general rise in total earnings variance, which is essentially driven by a quite dramatic rise in long‐run earnings inequality. The patterns across age categories of the two variance components are almost opposite. Long‐run earnings inequality generally rises with age, but earnings instability is seen to generally decline with age, so that earnings instability is markedly highest among entry age workers. Unemployment rate effects are positive on almost all variance measures, while higher unemployment is associated with widened long‐run earnings differentials and greater short‐run earnings instability.     

The educational attainment of immigrants: trends and implications

"This paper uses the 1970, 1980, and 1990 U.S. Censuses to study trends in educational attainment of immigrants relative to natives. Immigrants have become relatively less highly educated, but have become more highly educated in an absolute sense. The effects of changes in relative educational attainment between immigrants and natives on earnings are studied. Educational differences are found to explain more than half the observed wage gap between the two groups. The paper also allows for non-linearities in returns to education. Sheepskin effects influence earnings in different ways for natives and immigrants. Differences in returns to pre- and post-migration education also appear. The paper also finds evidence that immigrants crowd natives out of education, although the effects are stronger in secondary than in postsecondary education."     

Can Minimum Wages Close the Gender Wage Gap?

Using manufacturing plant‐level census data, this paper demonstrates that minimum wage increases in Indonesia reduced gender wage gaps among production workers, with heterogeneous impacts by level of education and position of the firm in the wage distribution. Paradoxically, educated women appear to have benefitted the most, particularly in the lower half of the firm average earnings distribution. By contrast, women who did not complete primary education did not benefit on average, and even lost ground in the upper end of the earnings distribution. Minimum wage increases were thus associated with exacerbated gender pay gaps among the least educated, and reduced gender gaps among the best educated production workers. Unconditional quantile regression analysis attests to wage compression and lighthouse effects. Changes in relative employment prospects were limited.     

The wage gap between Francophones and Anglophones: a Canadian perspective, 1970–2000

Abstract. The wage gap between Francophone and Anglophone men from 1970 and 2000 fell by 25 percentage points within Quebec, but only by 10 points Canada‐wide, largely because the wages of Quebec Anglophones fell by 15 points relative to other Canadian Anglophones. Accordingly, the Canadian measure of the Francophone gap better reflects the changing welfare of Francophones than the Quebec measure. Over half of the reduction in the Canadian Francophone wage gap is explained by rising Francophone education levels. In Quebec, the declining number and relative wages of Anglophone workers is best explained by a falling demand for English‐speaking labour.     

Wage Inequality and Human Capital Formation under Migration Possibilities

I examine the problem in the relationship between wage inequality and human capital formation under migration possibilities. Unlike previous analyses, I incorporate the education market and the education price into the analysis, and assume that workers bear the pecuniary cost for receiving education. Given such an assumption, migration possibilities do not necessarily increase education demand since the larger demand for education raises the education price and lowers the net return on education. By modelling an economy where workers in the home country (the labour‐sending country) comprise skilled and unskilled workers and they can migrate to the foreign country (the labour‐receiving country), I show that brain gain and brain drain occur simultaneously in the home country. In particular, if wage inequality is larger in the foreign country than in the home country, skilled workers experience brain gain and unskilled workers experience brain drain in the home country. On the other hand, if wage inequality is sufficiently larger in the home country, brain drain occurs in skilled workers and brain gain in unskilled workers.     

Native-immigrant wage differentials in Greece: discrimination and assimilation

This article applies the Blinder–Oaxaca methodology in order to dissect the average earnings differentials between Greek workers and three different groups of immigrants into a part attributed to differences in characteristics and a part due to discrimination. It also seeks to identify the effect of assimilation (i.e. postmigration human capital) on immigrants’ earnings. We use information about 8429 individuals, of which 1185 are immigrants. The data are drawn from the Greek Labour Force Survey (2009). Our results suggest that discrimination is significantly higher for immigrants originating from non-EU countries than it is for EU foreigners, while it is negative for those who terminated education in Greece. Also, there is evidence that (i) post-migration human capital is a significant determinant of immigrants earnings, (ii) there is limited transferability of skills between sending countries and Greece and (iii) education is the main determinant of the wage gap between natives and immigrants.     

Signalling or Human Capital: Evidence from the Finnish Polytechnic School Reform

We use data from the Finnish polytechnic reform to distinguish between human capital and signalling theories of the value of education. We find that the reform increased the earnings of polytechnic graduates compared with those graduating from the same schools before the reform, as predicted by both the human capital and the signalling models. However, we also find that the relative earnings of vocational college graduates decrease after polytechnic graduates start entering the labour market. This finding is inconsistent with the pure human capital model and can be interpreted as evidence that supports the signalling model.     

Occupations,fields of study and returns to education

This paper considers several possible channels behind the well‐documented effect of education on earnings. The first channel is that education makes workers more productive on a given task, as in a conventional human capital framework. The second channel is based on the idea that education helps workers get assigned to higher‐paying occupations where output is more sensitive to skill. A third and final channel is that workers are more productive and earn more when they are matched to a job related to their field of study. Using data from the 2005 National Graduate Survey and the 2006 Canadian Census, I find that channels two and three account for close to half of the conventionally measured return to education. The results indicate that the return to education varies greatly depending on occupation, field of study and the match between these two factors.     

Multinational firms,acquisitions and job tasks

We revisit the question how inward FDI and multinational ownership affect relative labor demand. Motivated by the recent literature that distinguish between skills and tasks, we argue that the impact of multinational and foreign ownership on the demand for labor is better captured by focusing on job tasks rather than education. We use Swedish matched employer–employee data and find that changes of local firms to both foreign and Swedish multinationals increase the relative demand for non-routine and interactive job tasks in the targeted local firms. Hence, in a high-income country, both inward and outward FDI have a task upgrading impact on local firms. The effect is primarily driven by wage effects leading to increased wage dispersion for workers with different non-routine and interactive task intensity. We also show that the effect is not the same as skill upgrading since dividing employees by educational attainment does not capture changes in the relative labor demand. Hence, our results suggest a new aspect of the labor market consequences of FDI.     

The Impact of Computer Use On Earnings in the UK

The effect of new technology on relative demands for workers has been the subject of much research in economics. Krueger (1993) and others have studied the impact of computers on earnings in the US and elsewhere. Such studies have been criticised for ignoring the possibility of bias due to unobserved heterogeneity between computer users and non‐users, resulting in computer users not being a random sub‐sample of all workers. As well as looking at the effects of computers on earnings in the UK, this paper extends previous analyses by using a sample selection framework to deal with the bias problem. Results indicate not only that returns to computer use are positive but that it is important to correct for the sample selection bias.     

Child Labour's effect on long-run earnings: An analysis of cohorts

The effect of child labour on wages in adulthood is conceptually ambiguous. Children who work learn responsibility and work-ethic, increasing adult earnings. However, working children have less time for play and homework, hindering cognitive development, resulting in lower earnings. The limited existing empirical work is similarly confounding. This paper assesses the nexus between child labour and adult earnings using unique data from an Ecuadorian 2015 labour market survey. It applies novel instrumental variable regression techniques that account for earnings, education and child labour being jointly determined. The sample is divided into age cohorts (20s, 30s, 40s and 50+) to ascertain the long-run consequences of child employment at different stages of life. The results suggest that former child (and teenage) workers earn significantly less per hour. The analysis of cohorts reveals that the effect is stronger for older workers. This gives impetus to the hypothesis that child work hinders cognitive development, which becomes more evident when workers reach full maturity. The study concludes with policy recommendations.     

Career, experience and returns to human capital: is the dual labour market hypothesis relevant for the UK?

This paper investigates the relationship between career status, labour market experience and returns to human capital accumulation in the context of a two-tier, career and non-career labour market. Using micro data from the British Household Panel Survey (BHPS), this study detects wage and employment mechanisms that differ between these two tiers of workers. The paper finds no support for the hypothesis of strict duality, by which the returns to education are expected to differ across labour market segments, with the returns in career employment being high and positive and the returns in the non-career sector being close to zero. The paper, however, finds support for significant returns to current tenure only in the career sector and also for the scarring hypothesis, according to which part-time employment and unemployment experience have a negative effect on participation and earnings in the career sector. Finally, there is evidence that only non-career earnings are significantly affected by local demand conditions, in contrast to earnings in the career sector. Career status is modelled as an endogenous variable subject to an initial job choice.     

Like father like son? Revisiting the role of parental education in estimating returns to education in China

Parental education has been used as an instrument in the earnings equation to deal with the endogeneity problem of education. Recently, however, many have found that parental education can be a proxy for unobservable networking, which directly affects wages. This article revisits the role of parental education in estimating returns to education by introducing the “geographical isolation” theory. For migrant workers who receive an education and move around to work, parental education affects their education but otherwise is unrelated to their wages, which makes parental education a good instrument in the instrumental variable approach. For local residents who stay in the same place during childhood and adulthood, parental education can directly affect their wages, and is better introduced as a proxy variable using the control variable method. This article identifies the heterogeneous effect of parental education on wages for different Chinese cohorts and contributes to the debate between the control variable and instrumental variable methods in returns to education studies. Moreover, the idea of geographic isolation can help in the search for good instrumental variables for migrant workers, which is valuable when studying the large migrant population in developing countries such as Mexico, China, India, Vietnam, and many African countries.     

Allocation of Labor in Urban West Africa: Insights from the Pattern of Labor Supply and Skill Premiums

Using comparable data from five West African capitals, we assess the rationale behind development policies targeting high rates of school enrollment through the prism of allocation of labor and earnings effects of skills across the formal and informal sectors, and not working. We find that people with high levels of education allocate to the small formal sector, while less educated workers allocate to the informal sector. While high levels of education are given more value in the relatively smaller sectors of salaried employment, observed skills like education appear to be fairly unprofitable in the larger self-employment sector. The fact that only the small formal sector in urban West Africa both seems to absorb highly educated workers and provide high skill premiums may be an important reason for the observed low demand for education and high dropout rates.     

Challenging the Human Capital Orthodoxy: The Education-Productivity Link Re-examined*

The human capital orthodoxy has it that education is an investment, not only for the individual undertaking it but also for society when it devotes scarce resources to it The return to society on that investment is seen mainly in terms of the enhanced productive contribution made by more-educated workers. The measure of that greater contribution most often used by economists is the extra earnings the more-educated on average receive This paper re-examines the available evidence of links between education and productivity (and between earnings and productivity) and finds it to be inconclusive.
