Schooling,experience and earnings: The case of an LDC

This is an application of the strict human capital model in accounting for income inequality in an LDC. Using individual characteristics of 1600 male Moroccan full-time employees, differences in schooling and experience explain about 70 percent of relative earnings dispersion. This result is based on the existence of an 'overtaking year of experience' occuring within the first decade of the working life of the individual. Furthermore, an attempt is made to isolate the rate of return to training from the returns to schooling by analysing the earnings of illiterate manual workers differentiated by the level of their skill. The results regarding the relationship between the returns to schooling versus training, the overtaking point, and the explanatory power of human capital variables are remarkably similar to those obtained in advanced countries.     

Schooling,fertility and the labour market experience of married women

This paper discusses the role of formal schooling and child rearing in the determination of career path choice of women in the US. Data were collected from the adult educational component of the 1991 US National Household Education Survey. Data are available for about 12,568 respondents, of whom 6860 are female. It is established that, amongst others, expected earnings significantly affect the career path and the hours of work chosen by American women. Based on the results of the study, a number of conclusions have been drawn: 1) expectations of earnings affect women's choice of career path, including decisions such as labor market participation, the part-time work versus full-time work decision, and occupational choice; 2) the indirect and indirect effects of schooling and other variables on regime choice has been studied; the impact of schooling and fertility on women's labor supply follows an intuitively plausible pattern; 3) evidence provided here on the private rate of return to education confirms the findings of Bland that part-time workers do not receive a lower return than others; and 4) the importance of correcting for endogeneity and sample selection biases in the problem of earnings determination and career choice has been established.     

A dynamic Mincer equation with an application to Portuguese data

This article argues in favour of a dynamic specification of the Mincer equation, where the past observed earnings play the role of additional explanatory variable for current observed earnings. A dynamic approach offers an explanation why the return to schooling in terms of observed earnings is not independent of labour-market experience, as suggested by some recent empirical evidence for the United States.     

Screening and Human Capital in the Australian Labour Market of the 1990s

This paper presents tests of the screening hypothesis using data on adult males from the 1996 Australian Census of Population and Housing. These tests are based on comparisons of wage and salary earners and the self-employed, and public and private sector workers, as examples of screened and unscreened employments. The first test compares the mean levels of schooling, income and labour market experience in screened and unscreened sectors, while the second examines the returns to schooling and the goodness of fit of the earnings models for both wage and salary earning (separated into public and private sector employees) and self-employed groups. The results are equivocal, but suggest screening could be part of the earnings determination process in the Australian labour market.     

Education, credentials, and immigrant earnings

Abstract.  Using 1981 to 2001 Census data, we study how the human capital of immigrants is rewarded in Canada. We distinguish between years of schooling and degrees obtained in order to estimate 'sheepskin' effects – the gain in earnings associated with receipt of a degree, controlling for years of schooling. We find that immigrant years of schooling and immigrant work experience accumulated before arrival is valued much less than Canadian experience of comparable natives. However, for immigrants the increase in earnings associated with completing educational programs is generally higher than that of comparable natives. We provide both signalling and human capital interpretations of this finding.     

Work Effort, Moderation in Expulsion, and Illegal Migration

Illegal migrants supply a valuable productive input: effort. But their status as illegals means that these migrants face a strictly positive probability of expulsion. A return to their country of origin entails reduced earnings when the wage at origin is lower than the wage at destination. This prospect induces illegal migrants to exert more work effort than comparable workers who face no such prospect. The lower the probable, alternative earnings, the harsher the penalty that illegal migrants will be subjected to upon their return, for a given probability of expulsion, and the higher the level of effort they will exert at destination. While the home‐country wage that awaits the illegal migrants upon their return is exogenous to the host country, the probability of their return is not. Given the home‐country wage, a higher probability of expulsion will induce illegal migrants to supply more effort. Hence, different combinations of probabilities of expulsion and home‐country wages yield the same level of effort. Thus, variation in the extent to which receiving countries undertake measures aimed at apprehending and expelling illegal migrants can be attributed not to characteristics of the illegal migrants themselves but to a feature that pertains to the illegal migrants’ country of origin.     

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.     

Explaining male wage inequality in the Philippines: non-parametric and semiparametric approaches

The study examines the roles of experience and education in explaining the increase in wage inequality among Philippine male workers between 1988 and 1995. It also provides a methodological approach to the analysis of wage inequality by combining non-parametric methods with semiparametric additive models, using the variance accounting framework. Non-parametric density estimators allow flexibility in dealing with distributional inference while additive models yield marginal effects estimates under minimal assumptions on the functional specification of the wage–schooling and wage–experience relationships. The results show that much of the inequality increase from 1988 to 1995 was caused by greater variabilities in returns to schooling and experience among 1995 workers. The rise of the p90/p10 percentile ratio was caused by greater return variabilities on schooling and experience in the 90th percentile.     

Computer knowledge and earnings: evidence for Australia

This paper uses data on wage and salary workers in Australia in 1993 to examine the relation between computer knowledge and earnings. A unique feature of the data set that is used is detailed information on the types and levels of computer skills possessed by individual workers. The main objectives of the study are to contribute to understanding the magnitude and sources of the relation between computer knowledge and earnings. Similar to existing research it is found that there is a large and significant return to computer knowledge, but that the magnitude of the return is substantially reduced in regressions that include detailed occupation controls. Using the detailed information on workers’ computer skills the main finding is that earnings are significantly positively related to the number of types of skills and average level of skills possessed by a worker.     

SCHOOLING AND OCCUPATIONAL EARNINGS*

This paper investigates the relation between schooling and earnings across and within occupations. Across occupations earnings are positively related to mean education. Within occupations the variance in schooling levels is generally substantial, but within two thirds of the occupations no relation between schooling and earnings is observed, while in the remaining third the pattern of sensitivity varies considerably. The sensitivity of earnings to education is greater for white males than white females and substantially greater for whites than blacks. When the white sample is divided into age cohorts, the degree of sensitivity of earnings to schooling is found to be greater for younger cohorts than older ones, except for the youngest cohort in 1970. In the conclusion, a structural interpretation of the distribution of earnings is proposed to account for the findings.     

The gender difference in wages and the returns to schooling over the great recession in the U.S.

This paper examines the effects of the Great Recession on the gender difference in hourly wage and the rate of return to schooling in the United States. Using data from American Community Survey 2000–2015, we find that the male-female difference in hourly wage declined during and after the recession. The Great Recession decreased earnings for both men and women, especially for those with more education. We also find there is a significant gender difference in the effects of the Great Recession on the returns to schooling. The Great Recession increased the rate of return to schooling for both men and women, and the female-male difference in the returns to schooling decreased by 0.4 percentage points in the post-recession period. The change of the gender difference in the returns to schooling can be explained by the wage structure change for men and women over the recession.     

Testing and applying a theory of utility: An attempt to decompose income in compensatory and scarcity rents

Data on income after tax, schooling completed, job held, age, and ‘level of satisfaction’ of 2663 members of the Dutch Consumer Union have been used to estimate regression equations of two types. Type I may be called a specification of a utility function, Type II an ‘earnings function’ (where income after tax was used as earnings). For both types a number of alternatives were estimated both with regard to mathematical shape and with regard to variables included. Defining equitable or justified income differences as differences which do not change the level of satisfaction, a formula for equitable incomes for given combinations of job, schooling and age can be derived from Type I equations. All regression coefficients are found to be lower than the corresponding earnings function coefficients. The latter can then be decomposed into a ‘compensatory’ component and a ‘scarcity rent’ component.     

Heterogeneity in the economic returns to schooling among Chinese rural–urban migrants, 2002–07

This paper analyses the returns to schooling among Chinese rural migrants using data from the 2002 and 2007 China Household Income Project. Our non‐parametric estimates show substantial heterogeneity in the schooling rates of return among migrant workers. While the returns to schooling for the overall sample have increased over time, this result is driven by the substantial increases in the schooling coefficients of female migrants. We expect the endogeneity biases in the estimated schooling returns to be decreasing after considering the change in the ability distribution of migrant workers during 2002–07.

Why the earnings of the middle class declined: evidence from Japan

Using rich governmental micro data, we explore the reasons for the decline in earnings of the middle class in Japan. Many developed countries have seen the decrease in middle-class earnings, and Japan, long known for its solid middle class, is no exception. Our analyses revealed that the main reasons for the decline differ between males and females. The decrease in the earnings of middle-class male workers is due to the decrease in general human capital captured by returns to potential experience years. In contrast, the decrease in the earnings of middle-class female workers is mainly due to the increase in the supply of part-time workers. Furthermore, the firm-specific human capital captured by the return to tenure has increased only among high-wage male workers. This implies that Japanese firms invest in a selected few able workers, regardless of age, because they have been changing human resource strategy in response to economic globalization and changes in technology and the management environment.     

COMPUTER SKILLS AND WAGES*

Data from the 1993 Survey of Training and Education show that 52 per cent of males and 60 per cent of females had at some time used a computer. An analysis using earnings functions reveals that computer usage is associated with a wage premium of between 12 and 16 per cent. Experiments show that omission of a variable recording computer usage from a wage equation will result in a bias of between 10 and 15 per cent in the estimated return to a year of schooling and similar distortion to the estimated return to experience.     

On estimating earnings functions for LDCs

A technique is developed for estimating earnings functions from data in which both wage-earners and self-employed persons are included; it is argued that the return to schooling is overestimated if only wage-earners are in the sample. A procedure for simultaneously imputing labor incomes to the self-employed is also developed and carried out with 1971 data for Bangkok, Thailand. The evidence suggests that ceteris paribus the self-employed have labor earnings at least as high as their wage-earning counterparts.     

Reporting errors, ability heterogeneity, and returns to schooling in China

Abstract. This study is aimed at providing a more accurate estimate of the returns to schooling in China by controlling for unobserved ability heterogeneity and measurement errors. We identify a unique instrument to correct for the omitted ability bias. We find that the attenuation bias caused by measurement error dominates the omitted ability bias in the OLS estimation. Based on the GMM estimation, for young workers in China, the return to schooling is 15.0% overall and 16.9% for women.     

Estimating the economic return to schooling on the basis of panel data

This paper is concerned with estimating the economic return to schooling of men in the Netherlands. An IV approach is adopted to estimate a panel data model with random individual effects. The fact that older individuals have relatively less schooling than younger individuals is exploited to construct instruments, and GNP per worker at the time an individual turned 16 is included to control for birth-cohort effects. The estimated return to schooling is about 15%. Ignoring the endogeneity of schooling results in a lower return to schooling. Ignoring birth-cohort effects results in a lower return to work experience.     

Optimal Schooling Investments and Earnings: An Analysis Using Australian Twins Data

The potential impact that unobserved ability can have on both schooling and earnings outcomes has been modelled by Ashenfelter and Rouse (1998). This paper applies their model to the Australian Twins Sample. The best estimate of the return to schooling for genetically identical (or MZ) twins is 8.9 per cent. Measurement errors in the schooling data are shown to constitute a more serious problem than the omission of the family effects that impact on ability. Individuals from higher ability families receive a lower marginal benefit from their investment in human capital.
