Firm-level human capital and innovation: Evidence from China

This paper examines the role of human capital in firms' innovation. Based on a World Bank survey of manufacturing firms in China, we use two firm-level datasets: one from large metropolitan cities, and one from mid-sized cities. Patents are used as an indicator of innovation. The human capital indicators we use include the number of highly educated workers, the general manager's education and tenure, and the management team's education and age. We use the Negative Binomial and Instrumental Variables estimators to estimate patent production function models that are augmented by our human capital variables. We also use the zero-inflated Negative Binomial model to examine the likelihood of innovation. We find that the human capital indicators play an important role in influencing patenting, and that some of the human capital variables appear to have a greater impact on patenting in mid-sized cities. Our human capital estimates are obtained after controlling for firms' R&D, size, market share, age, and foreign ownership, as well as fixed effects to control for industry-specific characteristics, and firms' location and geography.     

农业转移人口地域歧视的工资效应分析

基于广东省顺德区的调查数据,使用无条件分位数回归及分解方法,文章分析了外来与本地农业转移人口的工资效应。结果显示:外来与本地农业转移人口面临不同的工资决定机制;地域差异对工资的影响存在异质性,只有收入在88%分位点以上的外来农业转移人口才会受到地域歧视的影响,且随着收入分位点的上升,工资受地域的影响变大;地域因素与人力资本因素交织,通过婚姻、教育、工作岗位和经验等变量的作用产生影响;教育对于外来农业转移人口的工资具有增长效应,但无法完全消除地域歧视的影响。因此,除了提高外来农业转移人口的教育水平,还需改善外来农业转移人口融入城市的条件,促进外来农业转移人口家庭融入城市。     

健康人力资本与性别工资差异

现有对性别工资差异的研究大多是基于教育、经验等人力资本对工资的影响进行分析而忽视了健康人力资本的作用。本文运用中国健康与营养调查数据,将健康人力资本引入工资决定模型,对我国劳动力市场上健康人力资本对工资的影响以及性别工资差异进行了实证分析。研究发现：健康人力资本是影响我国居民工资收入的重要因素;我国劳动力市场上存在明显的性别工资差异,女性工资显著低于男性;利用Oaxaca—Cotton的分解方法发现性别工资差异中大约只有20％可以被个体特征合理解释,余下的部分被认为是对女性的歧视和没能观测到的因素所致。健康人力资本对工资的边际贡献在性别之间的差异是性别工资差异的重要来源。     

Why Do Foreign-Owned Firms Pay More? The Role of On-the-Job Training

While foreign-owned firms have consistently been found to pay higher wages than domestic firms to what appear to be equally productive workers, the causes of this remain unresolved. In a two-period bargaining framework we show that if training is more productive and specific in foreign firms, foreign firm workers will have a steeper wage profile and thus acquire a premium over time. Using a rich employer-employee matched data set we verify that the foreign wage premium is only acquired by workers over time spent in the firm and only by those that receive on-the-job training, thus providing empirical support for a firm-specific human capital acquisition explanation.

Male–female wage differentials in Japan

This paper empirically analyzes the gender wage gap in Japan using a new data set KHPS2004 which contains a wealth of information on the work history of individuals. KHPS2004 enables us to estimate wage functions without overstating individual’s human capital accumulation by work experience especially for females. Neuman-Oaxaca decomposition method is employed to analyze why the gender wage gap appears to exist in Japan. Main reasons as follows. First, full-time work experience and seniority which affect significantly wages is shorter for females than for males. Second, there are significant differences in evaluation of full-time experience between males and females.     

Firm specific human capital and unemployment in a growing economy

This study analyzes how the intensive use of firm specific human capital in firms affects the unemployment rate. For this purpose, I introduce into an equilibrium search model the possibility that workers quit their jobs. A worker changes his job when a firm that newly enters into the market offers a higher wage than his current wage. If firm specific human capital is important, it is difficult for a worker to quit his job, and, in consequence, the number of workers who quit their jobs is small. Thus, the unemployment rate is low. If the speed of technology obsolescence is high, the unemployment rate is high.     

Migration and wage growth: a human capital approach

"The purpose of this paper is to analyze migration as an investment in human capital using panel data. [The authors] focus on two issues. The first is the economic motivation for migration and the reasons some movers receive high returns relative to other migrants. The second issue, and the major focus of the paper, is a test of the human capital model explaining wage profiles of nonmovers, first-time, and repeat migrants." The data are from the National Longitudinal Survey of Young Males, 1966-1971 cross-section, and concern the United States.     

Long-Term Attachments and Long-Run Firm Rates of Return

Long-term attachments between workers and firms are common. Numerous studies have examined worker returns to tenure, but little is known of firm returns to firm-worker matches. Yet these attachments represent a human capital asset quasi-held by the firm, which is not captured by traditional accounting measures of firm assets. Firms with large quasi-holdings of human capital will have higher measured return on assets, other things equal. Analysis of data on 250 large manufacturing firms supports the view that firms profit from long-term attachments with their workers. Consequently, unmeasured human capital assets contribute to the explanation of persistence in measured long-run excess profits across firms.

Patterns and Sources of Changing Wage Inequality in Chile and Costa Rica During Structural Adjustment

During their respective periods of structural adjustment, inequality increased more rapidly in Chile than in Costa Rica. Using a new technique which measures the effects of changes in the quantities and prices of individual dimension of human capital on overall wage inequality, we identify changes in wage premiums associated with more education as an important cause of the different inequality outcomes. We present evidence that the different education price effects were due to different rates of growth in the demand for more-educated workers. Furthermore, inequality increased in Chile despite a large equalizing education quantity effect.     

The effect of interruptions and part-time work on women's wage rate: A test of the variable-intensity model

Summary In this article we investigated the effects of interruptions of labour market participation and part-time work on women's gross wage rates, using the variable-intensity model. Women who interrupt their labour market careers suffer not only from depreciation, which effects all workers. Every year they do not participate they also miss experience. Part-time work mitigates the depreciation of human capital compared to a situation of non-participation. The expectation that part-time work — as opposed to full-time work — leads in the long run to a lower wage rate is confirmed.     

Firm-specific human capital in different market conditions: Evidence from the Japanese football league

This paper examined how and the extent to which obtaining skills to meet team specific human capital is important to improve football player’s performance by comparing the top league and the second league. Based on panel data of individual players during the 2012–2016 seasons of the Japan Professional Football League (J League), we found; (1) In the top-league, changing team reduced player’s performance and their performance improved as player’s tenure of the team and also tenure of J League increased. (2) returns from acquiring team specific skills on time of play in the game increase and then decrease as years have passed. (3) benefit from moving team depends on the timing of moving, and so rookie players can benefit from moving when team tenure reach 4 years or more. (4) In the second league, neither team tenure nor experience of the professional football player does not influence player’s performance.     

人力资本、歧视与农民工收入——基于浙江省问卷调查数据的实证研究

本文基于人力资本理论和歧视理论对农民工和城镇职工工资差距进行的实证研究表明,人力资本是导致农民工低收入的主要原因,其中教育对工资差距具有决定性影响;歧视对农民工收入起重要作用,其中反向歧视已成为农民工歧视的主要表现形式。实现农民工收入增长和城乡劳动者平等就业必须"两手抓",一手抓农民工人力资本提升,一手抓制度改革消除对城镇职工的保护和偏袒。     

Active labour market policies and job tenure

In this paper, we study the effect of subsidised on-the-jobtraining, training for the unemployed and pure wage subsidieson job tenure. Correcting for selection biases, we find thateach of the labour market policies increases the length of jobtenure. Despite the sensitivity of the estimates to the parametricassumptions with respect to the unobservables, the effect ofsubsidised on-the-job training schemes is always found to besignificantly positive. Training programs for the unemployedand pure wage subsidies always have a positive, but statisticallynon-significant effect Our results provide some support forhuman capital theories as opposed to matching theories.     

Equal Convergence? Convergence Patterns Among Immigrants by Occupation

This study examines the immigrant-native wage gap in the United States using 2019 Annual Social and Economic Supplement data from the Current Population Survey. Ordinary least squares regression analyses were used to estimate the wages of immigrants while controlling for human capital characteristics, sociodemographic factors, and time since arrival in the United States. The results demonstrate that the wage gap converges with more time spent in the United States, likely due to increased work experience and language proficiency, but does not completely diminish. Separate regressions are conducted for different occupational groups. Occupations are shown to be a large contributor to the differential, as wages differ significantly more in unskilled occupations such as manual labor or transportation. The possibility of labor market discrimination is explored as a reason for the wage gap, with the Blinder-Oaxaca decomposition showing that only 68% of the wage gap can be explained by the included explanatory variables.

     

Black-white wage differential: The relative importance of human capital and labor market structure

This article uses the decomposition analysis developed by Neumark and the 1987 CPS data to investigate the relative importance of human capital and labor market structure in explaining the observed wage differential between white males and blacks (both male and female). We find that labor market structure, as opposed to differences in human capital, explains a relatively large portion of the wage gap between white males and blacks. In addition to blacks and whites being paid different wages for the same work, they are also given unequal opportunities. This means that narrowing the human capital gap between the races will not be enough to close the wage gap, as argued by human capital theorists. It is equally important to pursue policies that provide access to higher paying jobs and industries for blacks.     

Segmentation and discrimination in China's emerging industrial labor market

This article analyzes wage-setting behavior in four types of enterprise: state-owned enterprises (SOEs), township and village enterprises (TVEs), joint ventures (JVs), and foreign-invested firms (FIFs) in China's light consumer goods industry in 1998. We find that there is no significant difference among the four types of firms in the returns to education, while FIFs pay a wage premium for experience. Gender wage discrimination is found equally across all four firm types. However, the wage advantage enjoyed by urban residents seems to have disappeared across all ownership categories.     

全球生产网络、贸易结构与工资差距：来自中国的证据

论文通过建立全球生产网络的中间投入品模型,实证分析中间品贸易对一国技术劳动力和非技术劳动力工资差异的影响。研究发现：加工贸易是中国融入全球生产网络的典型形态;其出口会扩大对技术和非技术劳动力的需求。但技术劳动力的工资上涨幅度要高于非技术劳动力的工资涨幅,从而使相对工资差距扩大。短期内,中间品的进口减少了技术劳动力的需求和就业,但长期来看中间品进口会扩大对技术劳动力的需求,相对工资差距拉大。人力资本投资的供给增长由于未能满足劳动力市场的需求,从而在一定程度上表现为工资差距拉大;但长期来看,人力资本积累机制的完善使得相对工资差距会逐渐缓和。     

Human Capital and Hours Worked of Children in Cambodia: Empirical Evidence for Policy Implications*

This study uses data from the Cambodian Child Labor Survey 2001/02 (CCLS‐2001/02) to investigate the trade‐off between child labor and their human capital formation. It also investigates the determinants of child schooling and that of the income earned from child labor. This study finds that children's education is a significant determinant of their wage rate, which implicitly explains the logic behind the household's decision to allow a child to both work and study, and thus explains why parents keep investing in their children's education. We also find that non‐poor households and fathers’ and mothers’ education have statistically significant effects on child schooling. Finally, this study has found that if children's average working hours are below the threshold level of 22 h per week, then education is not affected. These research findings have policy implications for the human capital development of children, as well as for broader social policy in Cambodia.
