Technology,Labour Characteristics and Wage‐productivity Gaps*

We use plant‐level employer–employee data in production functions and wage equations to examine whether wages are based on productivity. We use a stepwise procedure to find out how the results are influenced by the kind of data that is available. The models include shares of employee groups based on age, level and field of education, and sex. The gap between the age‐related wage and productivity effects increases with age. Education increases productivity, but wage under‐compensates productivity especially for those with the highest level of non‐technical education. For women the results depend greatly on the specification and method used.     

Human capital revisited: The role of experience and education when controlling for performance and cognitive skills

Human capital theory predicts that differences in wages arise because of differences in human capital. The latter can be accumulated in two ways: through experience and education. Using matched firm–worker data for the Ghanaian Manufacturing sector we first test whether changes in wages over the life cycle reflect changes in performance, following the methodology of Medoff and Abraham [Medoff, J.L., &; Abraham, K.G. (1980). Experience, Performance, and Earnings. Quarterly Journal of Economics, 95(4), 703-736; Medoff, J.L., &; Abraham, K.G. (1981). Are Those Paid More Really More Productive? The Case of Experience. Journal of Human Resources, 16(2), 186–216]. We find that wage–seniority profiles are independent of performance – a result that holds when controlling for firm fixed effects. Extending the analysis, we include a control for on-the-job-training and find that it does not attenuate the seniority profile, which is also at odds with human capital theory. We do find however that firm characteristics play an important role. Wage–seniority profiles are steeper in large firms, but performance profiles are not, suggesting that the results from Medoff and Abraham are specific to large firms. We then assess the role of education. Our results confirm that education is important for the allocation to job levels. Using data on cognitive ability, we also find that the effect of education on wages is at least partially because it signals cognitive ability. We also find evidence that the returns to education are not related to performance, while the returns to cognitive ability are.     

Immigrant wage profiles within and between establishments

Life cycle wages of immigrants from developing countries fall short of catching up with wages of natives. Using linked employer–employee data, we show that 40% of the native–immigrant wage gap is explained by differential sorting across establishments. We find that returns to experience and seniority are similar for immigrant and native workers, but that differences in job mobility and intermittent spells of unemployment are major sources of disparity in lifetime wage growth. The inferior wage growth of immigrants primarily results from failure to advance to higher paying establishments over time. These empirical patterns are consistent with signaling disadvantages of immigrant job seekers, but not with the explanation that low wage growth follows from inferior information about employers and job opportunities.     

Productivity,seniority and wages: new evidence from personnel data

Wages may be observed to increase with seniority because of firm-specific human capital accumulation or because of self-selection of better workers in longer jobs. In both these cases, the upward sloping wage profile in cross-sectional regressions would reflect higher productivity of more senior workers. If this were true, the observation of an effect of seniority on wages would depend on the presence of controls for individual productivity. In this paper we replicate, using personnel data from a large Italian firm, the results of the pioneering work of Medoff and Abraham [Quarterly Journal of Economics (1980); The Journal of Human Resources, 15(2) (1981)] in which supervisors' evaluations were used as productivity indicators. Since the validity of supervisors' evaluations as measures of productivity has been widely criticised, we extend the work of Medoff and Abraham using different direct measures of productivity based on recorded absenteeism and misconduct episodes. Both these indicators and supervisors' evaluation suggest that the observed effect of seniority on wages does not reflect a higher productivity of more senior workers. Only at the lowest levels of the firm's hierarchy, the human capital theory contributes to explain the effect of seniority on wages. At least at all other levels, the explanation of the observed upward sloping profile has to be based on theories in which wages are deferred for incentive or insurance reasons.     

Seniority wages and establishment characteristics

A representative linked employer-employee panel and an innovative two-step estimation strategy are used to show that large and profitable establishments as well as establishments with a highly qualified workforce pay high seniority wages. Also collective bargaining coverage, works councils and reduced working time for older employees are positively correlated with seniority wages, the share of foreigners, females as well as initial wage levels for job entrants are negatively correlated. These results support an agency based motivation for seniority wages with older employees' wages set higher than their productivity.     

Returns to education and wages in Turkey: robust and resistant regression

In this study, we follow the human capital theory for wage determination and analyze the differentials in returns to education, returns to experience and gender wage gap using usual mincerian wage equation by using OLS, robust and resistant regressions. This study presents evidence on the returns to education in Turkey. The results clearly show that for female employees, education to returns is higher than for male employees. When the results of returns to experience have been studied, it is observed that males definitely have a higher return than females in the years 2003 and 2006.     

Analysis of the practice of job evaluation in the metal industry in Turkey

Job evaluation's main aim is to establish a fair wage structure. Its main principle is ‘equal pay for equal work’. ‘Metal Industry Job Grouping System’ (MIDS) has been in the metal industry in Turkey for more than 20 years. The results of the practice of the system were measured by the Gini coefficient. By the findings, the average wages of the job groups are different enough from each other by their job groups in the way the wage of the bigger number job group is higher than the smaller except the job group two in the industry. However, the wages are far from the principle ‘equal wage for equal job’ within the same job itself. In addition, the workers make use of bonuses and social benefits. The effect of social benefits of them on the wage structure is positive within the same job group and negative between different job groups within the same company. Nevertheless, the effect of both bonuses and social benefits on the wage structure is negative between the companies because, between them they are different from each other. Job group and seniority affect the wage structure. Seniority has a socio-psychological self-producing dynamic. The distribution of seniorities within the same job group has negative effects on the wage structure. However, this fact for each worker disappears for the long term since the worker of today who has short-term seniority will be the one of tomorrow who has long-term seniority. Therefore, for each worker, the wage structure gets closer to the principle ‘equal wage for equal job’ within the same job group itself over time.     

Returns to Skills and the Distribution of Wages: Spain 1995–2010

In contrast to the pattern observed in other developed countries, the Spanish wage distribution compressed between 1995 and 2006 and became more disperse afterwards, so that in 2010 wage inequality was roughly similar to 1995. In this paper, we analyze the role of supply and demand factors when accounting for these facts. We start by decomposing observed wage changes into changes in the composition of the labour force and changes in the returns of workers' and jobs' characteristics. The results indicate that the compression of the wage distribution between 1995 and 2006 is largely explained by changes in returns, and particularly, by a decrease in the returns to education. We show that both the increase in the supply of high‐skilled workers and the increasing weight of low‐skilled occupations are related to the decreasing trend in the skill premium over this period. In contrast, the widening of the wage distribution after 2006 is largely explained by an increase in the relative demand for high‐skilled workers generating an increase in the school premium.     

The effects of families and ability on men's education and earnings in Britain

The paper estimates the returns to education for a cohort of men born in Britain in March 1958 who have been followed since birth until the age of 33. The data used has a wealth of information on family background including parental education, social class and interest shown in the child's education as well as measures of ability. These variables are typically missing in studies looking at the returns to schooling. In the paper, we find that the average return to an additional year of full-time education for the UK men is somewhere around 5 1/2% to 6% even after correcting for the effects of measurement error. The paper also presents evidence that the returns to an additional year of schooling in the UK are heterogeneous. In particular, the paper finds some evidence that men with lower tastes for education, have significantly higher marginal returns to education. The results of the paper suggest that recent IV estimates of the returns to schooling in the UK, which exceed typical OLS estimates, may overestimate the average marginal return for the population of men as a whole.     

Urban effects on participation and wages: Are there gender differences?

This paper estimates participation and wage equations using panel data from the United Kingdom to explore gender differences in urban wage and participation premiums. The results suggest a small but economically significant urban participation premium for women but none for men. Results from the wage estimations suggest that after controlling for sample selectivity, observed and unobserved heterogeneity, the urban premium is larger for women. This wage premium is also larger for married or cohabiting women relative to others. There is also evidence of higher urban returns to experience for men and lower urban wage depreciation for both men and women.     

Firm-specific Human Capital Accumulation: Evidence from Brazil*

We introduce firm-specific returns to experience and tenure into a standard two-way fixed effects model, show that they are separately identified under the standard exogenous mobility assumption and with sufficient between firm mobility, and provide a new evidence on heterogeneity of returns to experience and tenure across firms using the administrative data from Brazil over the years 1999–2014. We document that (1) returns to tenure are not strongly related to firm wage premia, (2) returns to experience are strongly negatively correlated with firm wage premia, (3) the relationship between firm wage premium and return to experience is stronger for ‘blue collar’ firms.

Heterogeneous economic returns to higher education: evidence from Italy

This paper uses official Italian micro data and different methods to estimate, in the framework of potential outcomes, the marginal return to college education allowing for heterogeneous returns and for self-selection into higher education. Specifically, the paper is focused on the estimation of heterogeneity of average treatment effect (ATE) on a cohort of college and high school graduates using the 2008 survey on household, income and wealth of the Bank of Italy. Methodologically, this study was carried out by using both propensity-score-based (PS-based) methods and a new approach based on marginal treatment effects (MTE), recently proposed by Heckman and his associates as a useful strategy when the ignorability assumption may be violated. In the PS-based approach, heterogeneous treatment effects are estimated in three different manners: the traditional stratification approach (propensity score strata), the regression adjustment within propensity score strata and, finally, a non-parametric smoothing approach. In the MTE approach, the treatment effect heterogeneity across individuals is estimated in a parametric as well as a semi-parametric strategy. Our empirical analysis shows that the estimated heterogeneity is substantial: following MTE based results (quite representative of other methods) the return to college graduation for a randomly selected individual varies from as high as 20 % (for persons who would add one fifth of wage from graduating college) to as low as ?22 % (for persons who would lose from college graduation), suggesting that returns are higher for individuals more likely to attend college. Furthermore, the results of different methods show very low (point) estimates of ATE: average college returns vary from 3.5 % by the PS-smoothing method to 1.8 % by the parametric MTE method, which also leads a greater treatment effect on treated (5.5 %), a moderate, but significant sorting gain and a negligible selection bias.     

Seniority, external labor markets, and faculty pay

We estimate the returns to seniority (the wage-tenure profile) for university faculty, and the degree to which these returns respond to entry-level salaries (or opportunity wages)—a relationship unexplored in work to date. Using data on faculty at a Big Ten university (ours), we estimate elasticities of senior-faculty salaries with respect to entry-level salaries, and find that these elasticities decline with seniority. The evidence provides an explanation of faculty salary compression and suggests the importance of controlling for entry-level salaries in obtaining estimates of the returns to seniority.     

The transformation of the wage and performance appraisal system in a Japanese firm

This paper analyses how performance appraisal has affected the wages of employees in a unionized Japanese firm over time, using firm-level wage and performance appraisal data. Data show that the wage and performance-appraisal systems have been shifting to a performance basis, and away from the heavy reliance on age and seniority characteristic of the old systems. In the process, wage differentials among employees are becoming wider, particularly among those 37 to 41 years old and those 49 to 55 years old. Management introduced the new wage system through a process of concessionary bargaining. Surprisingly, employees, rather than the enterprise union, were able to convince management to modify their initial plans during bargaining over the new wage system.     

Employer learning and the returns to schooling

Theoretical models of employer learning suggest that an employee's education is an important signal to the employer initially. Over time, however, the returns to schooling should decrease with labor market experience and increase with initially unobserved ability, since the employer gradually obtains better information on the productivity of an employee. Replicating US studies using a large German panel data set (GSOEP), we find no evidence for the employer learning hypothesis. Differentiating blue-collar and white-collar workers and estimating quantile regressions, however, leads to the conclusion that employer learning takes place for blue-collar workers at the lower end of the wage distribution.     

Tenure and output

A key tenet of the theory of human capital is that investment in skills results in higher productivity. The previous literature has estimated the degree of investment in human capital for individuals by looking at individual wage growth as a proxy for productivity growth. In this paper, we have both wage and personal productivity data, and thus are able to measure of the increase in workers' output with tenure as evidence of the degree of learning on the job. The data is from an autoglass company. Most of production occurs at the individual level so measures of output are clear. We find a very steep learning curve in the first eight months on the job: output is 53 percent higher after eight months than it is initially. Our data show that these output gains with tenure are not reflected in equal percentage pay gains: pay profiles are much flatter than output profiles in the first year and a half on the job. For these data, using wage profiles significantly underestimates the amount of investment compared to the gains evident in output-tenure profiles. The pattern of productivity rising more rapidly than pay reverses after two years of tenure, although our evidence on this point is less reliable. Worker selection is also important. Workers who stay longer have higher output levels and faster early learning.     

EDUCATION AND ENTREPRENEURSHIP SELECTION AND PERFORMANCE: A REVIEW OF THE EMPIRICAL LITERATURE

Abstract This paper provides a review of empirical studies into the impact of formal schooling on entrepreneurship selection and performance in industrial countries. We describe the main effects found in the literature, we explain the variance in results across almost a hundred studies, and we put the empirical results in the context of related economic theory and the much further developed literature in labor economics (studying the rate of return to education among wage employees). Five main conclusions result from this meta‐analysis. First, the impact of education on selection into entrepreneurship is insignificant. Second, the effect of education on performance is positive and significant. Third, the return to a marginal year of schooling is 6.1% for an entrepreneur. Fourth, the effect of education on earnings is smaller for entrepreneurs than for employees in Europe, but larger in the USA. Fifth, the returns to schooling in entrepreneurship are higher in the USA than in Europe, higher for females than for males, and lower for non‐whites or immigrants. In conclusion, we offer a number of suggestions to move the research frontier in this area of inquiry. The entrepreneurship literature on education can benefit from the technical sophistication used to estimate the returns to schooling for employees.     

Intergenerational conflict and the political economy of higher education funding

We examine how a population's age distribution and a growing divide between the ethnic composition of older and young generations is likely to affect support for higher education funding. Using detailed survey data on voter preferences for higher education funding and precinct-level vote returns from locally-funded community college bond referenda in California, we find that older voters are significantly less supportive of higher education funding than younger voters and that support among older non-Hispanic white voters is particularly weak when those voters reside in a jurisdiction where the college-age population is more heavily Hispanic.     

After, before and during: returns to education in Hungary (1986–1998)

How valuable are the skills acquired under socialism in a market economy? This paper throws light on this question using unique data covering the years before and during transition (1986–1998) for about 3 million Hungarian wage earners. We find that returns to a year of schooling increased by 75% from 6.4% in 1986 to 11.2% in 1998. We also find that the private sector rewards formal education more than the public and, in terms of gender, although in 1986 women had greater returns to schooling than men, by 1998 this difference had been eliminated.
