Allocation and the earnings function

This paper stresses the view that earnings differentials should be interpreted in the light of allocation in the labor market. A model is developed that acknowledges the difference between individual levels of characteristics and the levels of such characteristics required in the job. It is applied to data sets for the Netherlands, with education as the most important variable. Neither the individual's education nor the requirements of the job alone are sufficient to determine earnings: they should be considered jointly. The earnings function containing allocation thus proves superior to the function derived from either human capital theory or from segmented labor market theory.     

ABILITY AND AGE-INCOME PROFILES

This paper is devoted to the personal distribution of income. The focus is on the relation between individual age and income and on the observed regularities in these age-income profiles. Empirically, age-income profiles show marked differences by occupation and by education. In general, with increasing levels of education both the level and the slope of the age-income profile increase; there is also a tendency of the variance of income to increase with age. Explanations of these facts are discussed. The human capital model is found defective in two ways: direct measurement of capital formation that occurs through on-the-job training is not feasible and the demand side of the labor market is ignored. Lydall's approach stressing the role of ability development is considered promising, yet lacking a theoretic integration of the relevant factors. The relation between education and ability is also reviewed. It is concluded that IQ is an important variable associated with educational attainment, but that its explanatory power with respect to earnings in addition to length of schooling is almost negligible. Moreover, its development over age cannot be held responsible for the age-income profile, since its peak is far too early. Ability as a multidimensional concept appears attractive, though empirical problems are manifold. Finally, interesting direct empirical evidence on productivity development with experience is found in the literature on the learning curve. In certain jobs, where productivity can be measured directly, increasing experience on the job produces an asymptotic productivity profile. In the final section the conclusions are reviewed and used to briefly indicate a new theory. According to this theory, capabilities are the key variables in the labor market. Individual preferences regarding employment of these capabilities guide decisions about job choice. The labor market rewards capabilities and capability development over age explains the age-income profile.     

Compensating wage differences

The paper develops a model of the allocation of workers to jobs based on individual's preferences for job satisfaction vs earnings. Given the distribution of levels of job satisfaction and productivities, it is possible to solve explicitly for wages as a function of job satisfaction. More productive individuals will take more (less) satisfying jobs whenever the elasticity of substitution between job satisfaction and earnings is less (greater) than one. The paper also discusses the effects of inequality on earnings of high and low productivity workers and the effects of compensating wage differences on the distribution of earnings.

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.     

The impact of job mobility on earnings growth of migrant workers in urban China

Using survey data on migrant workers in urban China, this paper carries out a positive study on the impact of inner-industrial and inter-industrial job shifts on earnings growth of migrant workers. Results show that low human capital, low employment grades and low income are the most important reasons for migrant workers to switch jobs. The migrant workers who are young, unmarried new entrants with low level of education, no training and low income tend to change their jobs within the industry. And those who have high income and who find their jobs by themselves are more likely to switch jobs inter-industrially. Inner-industrial job switches have a significant positive impact on earnings growth of low-income migrant workers and a significant negative one on that of high-income migrant workers. Moreover, inter-industrial shifts have a significant negative impact on earnings growth of migrant workers of all income levels. The inner cause for the positive effect of inner-industrial shifts lie in the fact that the cumulative effect of years of service within enterprises is not obvious while continuing engagement in the same type of job within an industry will lead to accumulation of qualifications, which has a significant augmentation effect on earnings of migrant workers.     

STOCKS AND DEPRECIATION OF HUMAN CAPITAL: NEW EVIDENCE FROM A PRESENT-VALUE PERSPECTIVE

Responding to a perceived growing interest in human wealth estimates, this paper offers a framework for measuring the aggregate stock of human capital and then implements the procedure for the United States male population age 14 to 75. Unlike previous estimates of human wealth that are based upon historical or resource costs, these estimates measure the capital stock as the discounted resent-value of expected lifetime returns. In the estimation, returns are equated with earnings data from the 1970 U.S. Census 15 percent Public Use Sample for out-of-school males, adjusted for employment and survival probabilities, adjusted for an assumed exogenous growth in future earnings, and discounted at 7.5 percent.
We provide cross-sectional estimates of individual stocks of human capital by age and educational attainment, as well as expected lifetime wealth profiles for individuals by level of education. These individual profiles can be used to obtain direct estimates of age-specific depreciation which suggest human capital is subject to significant and prolonged appreciation before nearly straight-line depreciation begins around middle age. This finding is all the more significant since resource-cost estimates of human capital which must assume a depreciation pattern to obtain stocks have always imposed a much faster rate much sooner.
Finally, an aggregate estimate of the stock of human capital for all males is supplied and its sensitivity to the choice of the discount rate, tax laws, and expected exogenous growth is analyzed. This seemingly-conservative stock estimate is then compared to a much lower resource-cost estimate offered recently by John Kendrick. A discount rate over 20 percent would be needed to equate the two measures. In trying to reconcile the two figures, we raise some new questions about the validity of both approaches for human capital accounting.     

Cultural determinants of human capital accumulation: Evidence from the European Social Survey

Although economists commonly view the accumulation of human capital as a key driver of economic development, what drives cross-country differences in human capital accumulation remains poorly understood. I use an epidemiological approach involving second-generation migrants to test for a possible cultural gradient in individuals’ propensity towards human capital accumulation. Results indicate a strong relationship between country-of-origin culture and human capital accumulation and are robust to using years of education instead of individuals’ engagement in human capital accumulation as the dependent variable. Drawing on dimensions of cultural differences identified in culture frameworks developed by cross-cultural researchers, results further suggest that cultural emphasis on intellectual autonomy helps explain part of the observed differences in human capital accumulation. However, further work is needed to complete our understanding of the cultural roots of individuals’ propensity towards human capital accumulation.     

教育融资体制对代际流动性与不平等程度的动态影响：基于OL G模型的分析

传统的代际流动性研究并没有对代际流动性的短期值和长期值作有效区分,也未考虑人力资本形成中的不确定性,因而“代际流动性越高则不平等程度越低”这一分析结论并未在中国的现实中呈现。文章据此通过构建一个代际交叠模型比较分析了公共教育体制和市场教育体制下的代际流动性。模型动态分析发现：(1)公共教育体制下的不平等程度的长期值比市场教育体制下更低。(2)代际流动性短期值的升高并不总是伴随着不平等程度的下降,当社会受到某种剧烈冲击时可能发生两者同升同降的情况。(3)政府进行激进式的教育体制改革会使人力资本收敛速率发生跃升,并且使不平等程度的短期值和长期值都增大,而代际流动性则会在突降后在逐渐收敛到新的更低的稳态值。(4)人力资本积累不确定性参数值反映了个体不可观测的技能或先天禀赋,是影响代际流动性和不平等程度的重要因素。不确定性的突然上升会使不平等程度的短期值迅速上升,并且会使不平等程度的长期值达到新的高位,虽然代际流动性短期值也会迅速上升,但依旧会逐渐收敛到以前的稳态值不变。文章的研究有益于厘清代际流动性与不平等程度的复杂关系,也能为相关实证研究提供参考。     

The relationship between job satisfaction and managerial remuneration in small and medium-sized enterprises: an empirical test of ‘comparison income’ and ‘equity theory’ hypotheses

The relationship between job satisfaction levels and the remuneration of non-owner managers employed by a sample of 97 UK small and medium sized enterprises (SMEs) is investigated. The main empirical findings are that relative remuneration levels appear to be largely explained by differences in human capital and job/firm characteristics and that job satisfaction is positively related to deviations from these estimated comparison-income levels. Moreover, the equity theory expectation that individuals with the least prospect of redressing payment inequities will have the greatest incentives to respond to payment inequities by congitive adjustment is also supported. The results indicate that job satisfaction levels for individuals expecting to remain in their current post are not significantly affected by current payment inequities. For those managers who expect to move firms, the amount of payment inequity has a significantly positive effect upon their job satisfaction.     

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.     

金融发展与地区实体经济资本配置效率-来自省级工业行业数据的证据

职位隔离是形成性别收入差距的重要机制.本文构建一个引入了职位晋升机制的收入差距分解方法,利用2006年中国综合社会调查数据,考察了职位隔离对性别收入差距的作用,且在统一的模型框架内识别和估计了职位内工资歧视(同工不同酬)和晋升歧视的程度.研究结果发现,女性过多地集中于职位"金字塔"结构的底层.尽管职位晋升的工资效应不存在显著的性别差异,但约41%的性别收入差距是由于职位隔离导致的.工资歧视是职位层级内部性别收入差距的主要来源.与之类似,职位晋升歧视能够解释1/4的性别收入差距.因此,除了同工同酬政策,促进职位晋升的机会平等是缩小性别收入差距的重要措施,意即"同酬"还需"同工".     

Immigrant Earnings Adjustment: The Impact of Age at Migration

Human capital theory, in conjunction with Chiswick's (1978 ) and Borjas' (1998) work, implies the post-migration path of immigrant earnings is likely to depend on the age at migration. An adaptation of Borjas' (1998) model of immigrant wage determination is presented which predicts, for a given stock of human capital at the point of migration, lower initial earnings for younger arrivals, but faster earnings growth with time in the destination country. Empirical tests on data for Australian immigrants provide qualified support for the hypothesis that initial wages are, ceteris paribus , increasing in age at migration and the rate of wage growth is decreasing in age at migration.     

A structural model of human capital and manufacturing sector change

The relationship between manufacturing job losses per capita, changes in manufacturing earnings per worker, and human capital investment is examined empirically at the level of nearly 3,000 U.S. counties over the period 1980–90. Hypotheses tested address the questions of whether the sectoral composition of the local economy (in this case with an emphasis on manufacturing) affects per worker earnings growth and investment in human capital, and whether investment in human capital in turn affects the economy's sectoral composition and earnings growth. The simultaneous equations estimation reveals direct and indirect effects of initial levels of the endogenous variables on their change during the 1980s. These effects are compared with comprehensive effects obtained using a reduced form regression.Research underlying this paper was funded in part under the National Research Initiative, Competitive Grants Program of USDA/ERS (Grant no. 93-37401-9367).

Fertility Decisions and Gender Differences in Labor Turnover, Employment, and Wages

A striking observation of the U.S. and other labor markets is the weak position of women in terms of job attachment, employment, and earnings relative to men. We develop a model of fertility and labor market decisions to study the impact of fertility on gender differences in labor turnover, employment, and wages. In our framework, individuals search for jobs and accumulate general (experience) and specific (tenure) human capital when they work. They can also increase their wage by moving to a job of higher quality. Labor market decisions (e.g., job acceptance and job mobility) may differ across genders: females that give birth may decide to interrupt their labor market attachment in order to enjoy the value of staying at home with their children. The model economy is successfully calibrated to match aggregate statistics in terms of fertility, employment, and wages. We find that fertility decisions generate important gender differences in turnover rates, with long lasting effects in employment and wages. These differences in labor turnover account for almost all the U.S. gender wage gap that is attributed to labor market experience by Blau and Kahn (2000, Journal of Labor Economics15(1), 1–42). The model also implies a very small role of tenure capital in accounting for wage differences between males and females (gender gap), and between females with and without children (family gap).

Human capital and measurable dynamic gains from economic integration: An application to the economic integration of North and South America

The paper looks at the source of dynamic gains to trade liberalization using a two-country model with both physical and human capital accumulation. The model is calibrated and used to examine the effect of the economic integration of Canada and the United States with Latin America. The analysis assumes that differences in productivity levels between regions are due entirely to differences in human and physical capital endowments. Key assumptions are that capital is internationally mobile and human capital formation is income constrained. The simulated impact of moving to a hemispheric free trade area is significant. The long-run impacts are also different from the short-run efficiency effect predicted by conventional static triangle-rectangle analysis. The long-runmultiplier effect on static output gains are on the order of 2.0 to 2.5 for the South—that is long-run output gains are 2.0 to 2.5 times predicted short-run static gains. In the case of the North, static predictions of gain are ambiguous in sign over the longer run; in some cases there are small dynamic gains-in others. small losses. Investment diversion toward Latin America is a prominent characteristic of the results.     

Economic Growth and Wage Stagnation in Peru: 1998–2012

From 1998 to 2012, the Peruvian economy exhibited rapid growth. Moreover, the composition of the labor force improved in terms of education and experience, two variables that are typically associated to higher human capital. The average worker in 2012 had a higher level of education and was one and a half years older than in 1998, reflecting the impact of the demographic transition. However, the average real wage was roughly constant. We show that a decline in the wage premium for education, and to a minor extent for experience, is responsible for the lack of growth in the average real wage. Had these two premia remained constant throughout the period of analysis, average labor earnings would have increased by about 2.6% per year, of which 0.7 percentage points are accounted for by the changes in the composition of the labor force in terms of age and education. We explore the role of the relative supply of workers with different levels of human capital as an explanation for the decline in the wage premium for education. Finally, we analyze the implications of these findings for some macroeconomic variables, as earnings and wage inequality, the labor share and total factor productivity.     

The visible and the hidden behind migrants’ human capital

The paper explores differences in human capital between the Israel-born and immigrants within the Jorgenson and Fraumeni model. Using a unique ‘imputed education’ method, the study answers whether the immigrants’ level of education, in fact, reflects their human capital. The results show that immigrants during their first years do not work in an occupation that fits their education; this holds their estimated human capital below that of the Israel-born. Over the years, the gap between immigrants and non-immigrants in per-capita human capital contracted from 30 percent to 14 percent on average, or, using the imputation method, from 23 percent to 9 percent. In addition, the gaps between the immigrants and nonimmigrants and those between original education and imputed education contract at higher education levels. Some immigrants were able to find an occupation that matched their education and to integrate into the local job market, and the per-capita human capital of immigrants and nonimmigrants converged.     

THE RELATIONSHIP BETWEEN HIGH SCHOOL MARIJUANA USE AND ANNUAL EARNINGS AMONG YOUNG ADULT MALES

This article uses a unique panel data set to examine the relationship between high school marijuana use and annual earnings at age 29. The authors estimate a series of OLS models that incrementally add potential confounding variables, including marijuana use at age 29. The analysis finds that part of the negative relationship reflects an indirect pathway whereby early marijuana use affects human capital accumulation, which in turn affects earnings. Moreover, the authors find evidence that the remaining association between early marijuana use and earnings, after controlling for differences in human capital, reflects the cumulative effect of marijuana use on cognitive ability and motivation.

Intergenerational Mobility and the Process of Development

This paper offers an explanation for some evidence that intergenerational earnings mobility is higher in more developed economies and that mobility is positively correlated with wage equality. In the model mobility promotes economic growth via its effect on the accumulation and allocation of human capital. Growth influences mobility via its effect on incentives to acquire education and its effect on liquidity constraints upon such acquisition. In the process of development mobility increases and the distribution of education becomes better correlated with ability. Redistributive policy has a negative effect on growth in developed economies and a positive effect in developing economies.
