Child Labor and the Interaction between the Quantity and Quality of Children

This article analyzes the impacts of child labor on the interaction between the quantity and quality of children in the spirit of Becker and Lewis. It shows that, without child labor, the quantity of children can be a normal good so that it increases with parental income under some fairly standard formulations. However, the correlation between fertility and parental income becomes negative when the role of child labor is considered. The model also implies that fertility increases with the wage rate of child labor. Moreover, it suggests that government intervention not only directly affects the supply of child labor but also influences parents' decisions on fertility, which indirectly determines children's labor market participations.     

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。     

Wage differentials between urban and rural-urban migrant workers in China

Since the end of the 1980s, the number of migrants working in the urban labor market has increased dramatically. However, migrant workers are treated differently from urban workers. In this paper we examine the labor market discrimination against rural migrants from the point of view of wage differentials using CHIP-2007 data. We apply Jann pooled method to deal with index number problem and use Heckman two step model to correct selection problem when decomposing the wage gap. The decomposition results show that a significant difference in wage gains persists between the two groups as late as 2007. In 2007 migrants only earned 49% of urban workers' income and 17% of the wage gap cannot be explained by observed factors. In detail, differences in educational attainment, work experience and distribution across industry, occupation, and ownership of enterprises account for most of the explained wage gap.     

Employment,income and economic identity in the U.S. virgin islands

The explosive tourism-led growth experienced by the U.S. Virgin Islands during the 1960s and early 1970s reflected the duality of the Virgin Islands’ socioeconomic identity. Although growth was dependent on the U.S. economy and U.S. policies, it also reaffirmed the links the Virgin Islands had developed with the Eastern Caribbean labor market in spite of their unique history as a Danish and then an American colony. Relatively large scale inflows of Eastern Caribbean labor caused both general and relative wage effects, compression of the wage and income structures, and redistribution of income away from labor. Increased labor market segmentation exacerbated the inherent ambivalence of the Virgin Islands’ Eastern Caribbean identity. The nature of the transformation of employment and income in the Virgin Islands undermined the benefits derived by the indigenous labor force and established the bases of subsequent socioeconomic conflict.     

政府推动的就近城镇化能够消除工资歧视吗

随着大中城市城镇化空间的逐渐饱和以及农民工回流现象的出现,就近城镇化成为推进我国新型城镇化进程的重要模式。文章基于2017年中国流动人口动态监测调查(CMDS)数据,研究政府推动的就近城镇化对农村劳动力工资收入的影响发现:政府通过征地、户口改革方式推动的就近城镇化并不能够消除工资歧视,实现就近城镇化的农村劳动力在其他条件相同的情况下其工资水平仍然低于城镇本地职工,这一结论在纠正自选择偏差和样本选择偏差后仍然成立。机制分析发现,城镇劳动力市场针对实现就近城镇化的农村劳动力在就业机会方面的歧视与隔离已不明显,同工不同酬成为实现就近城镇化者面临的主要歧视形式,而城乡劳动力之间教育回报率的差异是导致同工不同酬的主要原因。进一步讨论发现,就近城镇化对于农村劳动力参保城镇职工保险具有显著的提升作用,而自我雇佣的就业形式则有助于打破城镇劳动力市场对农村劳动力的收入歧视。文章拓展研究了就近城镇化对农村劳动力工资收入的影响,为政府进一步推进以县域城镇化为主要形式的就近城镇化提供了研究参考。未来应持续推进城乡基本公共服务均等化,进一步缩小城乡教育质量差异,加强农村劳动力"同工同酬"的保护力度,稳步推进农村劳动力的就近城镇化。     

Effects of school closure on household labor supply: Evidence from rural China

This paper studies the effects of school closure on household labor supply exploiting China's large-scale rural primary school closing during the early 2000s. Using CHNS 1991–2011 and CHIP 2007–2008 datasets and a difference-in-differences approach, we find that school closure significantly increases the total annual income of mothers of primary school-aged children, which comes virtually entirely from increases in wage income, due to more participation, more working hours, and higher wage rates. This significant positive effect can plausibly be attributed to their migration responses: mothers engage in temporary rural-urban migration to care for children following school closure. We find no effects on fathers' income and migration behavior. Our study provides the first causal estimation of the impacts of school closure on household labor supply and sheds light on the migration decision-making of rural females.     

Evaluating public sector sponsored training in East Germany

Support of training has been a very important instrument ofactive labor market policy in East Germany. This paper attemptsan evaluation of the employment and wage effects of trainingsupported by public income maintenance outside of a firm. Afterdescribing the labor market developments in East Germany, weillustrate the evaluation problem. Then, we estimate a simultaneousmodel for participation in training, employment, and wages.Taking account of selection effects before participation, ourfindings mostly suggest positive though only partially significantlong-run effects of training on employment or wages.     

Top wage incomes in Japan, 1951–2005

Using wage income tax statistics, we construct continuous series of upper wage income shares in Japan from 1951 to 2005 to document the evolution of top wage incomes and investigate their long-run determinants. We find that, while the middle wage income class gained enormously both in absolute and relative terms during the period of high economic growth, the upper wage income class faired comparatively better after 1975. In particular, the shares of total wage accruing to the top 1% wage earners and above have risen steadily since the late 1990s. A simple time-series regression analysis indicates that marginal income tax rates, corporate performance, female labor force participation, and labor disputes are important determinants of top wage income shares in post-WWII Japan. Although not conclusive, our results suggest that much of the recent gains in wage income shares at the top can be explained by the changes in these four factors, placing a less emphasis on a story of structural change.     

Can Import Tariffs Deter Outward FDI?

In this paper we analyze a country's optimal trade policy when its labor market is unionized and firms are footloose. We show that an important objective for governments to use import protection is to prevent their domestic multinationals to go to a non-unionized location abroad and to serve their country from a distance. A domestic government will set a positive tariff to dissuade its multinational from engaging in outward FDI when the additional profits it repatriates, do not compensate for the loss of domestic union rent. To put it differently, we show that when the domestic labor market is unionized, trade liberalisation between countries with similar wage levels is likely to result in domestic welfare losses as a result of outward FDI. Only when wage differences between countries are large enough, can outward FDI improve domestic welfare and optimal tariffs will be zero. JEL Classification Numbers: L13, F23     

工资对个人劳动供给的非线性影响：部门市场化程度差异视角

从市场经济体制的建立到经济社会高质量发展，我国不同部门市场化程度有所差异，劳动供给的部门异质性随之体现。基于中国劳动力动态调查数据，结合汉森门槛回归模型和劳动供给模型，依托部门市场化程度的差异性，文章探讨了工资对劳动力个人供给的非线性影响及其部门异质性。主要得出以下研究结论：第一，我国市场部门与公共部门劳动力的个人劳动供给有所差异。第二，工资与个人劳动供给呈现非线性关系并且存在部门异质性。实证分析结果显示，工资对个人劳动供给的影响存在三个"突变点"，工资门槛均使得工资"激励效应"加强并呈现逐步增加的趋势。第三，劳动供给的工资门槛存在性别、城乡和行业异质性。第四，随着年龄增长、人力资本积累，个人劳动时间供给趋于降低，签署书面劳工合同使得市场部门劳动力工作时间显著增加，而政治面貌显著影响公共部门劳动供给。总体来看，无论是市场部门还是公共部门，我国劳动力个人供给曲线均未"向后弯曲"，国民经济高质量发展、改善收入分配格局、提升居民幸福感等议题需持续关注。     

市场化改革中的大学毕业生性别工资差异及歧视

以往文献认为,市场机制的不断完善会逐渐消除劳动力市场性别歧视,然而本文发现这一结论并不适用于目前大学毕业生劳动力市场。通过对不同市场化程度企业工作的河北省2007届大学毕业生抽样数据的实证分析发现,随着我国市场化进程的深入,不但大学毕业生性别工资差异明显扩大,而且歧视尤其是反向歧视所占比重也在加剧。本文认为,大学毕业生劳动力市场受传统文化影响程度还远远大于市场竞争作用的发挥。故只有进一步加大市场竞争,才能逐步消除劳动力市场的性别歧视因素。     

Wage Consequences of Rapid Tertiary Education Expansion in a Developing Economy: The Case of Thailand

In recent years, Thailand has experienced the emergence of “overeducated” workers as the supply of university graduates in Thailand has outpaced growth in high‐skilled employment opportunities. Using the 2007 to 2009 Thai Labor Force Survey, this paper quantifies the incidence of overeducation and estimates overeducation wage penalties among male university graduates. The results show that the incidence of overeducation is greatest among younger cohorts. Quantile wage regression results suggest that overeducation wage penalties for older workers capture the impact of unobserved low ability on wages. In contrast, persistent wage penalties of 11–26% across the wage/ability distributions for younger workers are consistent with structural imbalances in the Thai labor market. These imbalances make it difficult for university graduates to find jobs commensurate with their level of formal education and to achieve their full earning power. The wage penalties are especially large for new entrants into the labor market.     

Globalization and real wages in New Zealand 1873-1913

This paper reports annual real wage indexes for laborers and for workers more generally in New Zealand, adjusted for purchasing power parity, for the years 1873-1913. These data are used to include New Zealand in the debates surrounding international wage convergence. On the basis of time series tests we find evidence of an integrated trans-Tasman labor market. Productivity, the terms of trade, and swings in labor’s income share, rather than immigration, shaped New Zealand’s wage growth.     

去工业化对收入不平等的影响:机制分析与实证检验

基于126个国家1991-2017年的面板数据,考察了去工业化对收入不平等的影响。研究发现,去工业化会显著加剧收入不平等程度,这在发展中经济体尤为显著。从传导机制看,去工业化既可以通过劳动力就业转移直接影响收入不平等,也可通过非熟练劳动力就业和服务业部门就业分化间接影响收入不平等。一方面,去工业化导致非熟练劳动力受到更大冲击,致使该部分劳动力失业,加剧收入不平等;另一方面,去工业化导致非熟练劳动力的就业从工业的高薪部门转移至服务业的低薪部门,最终影响收入不平等。进一步研究发现,在可能存在"过早去工业化"的国家去工业化对收入不平等的作用更加明显。因此发展中经济体要着重预防由于去工业化可能带来的收入不平等程度恶化。     

Evidence on the Volunteer Labor Supply of Married Women

I estimate a significant, positive wage elasticity of married women's volunteer labor supply from 1975 to 1976 U.S. time diary data. Increases in the number of children in the household significantly raise participation rates but reduce volunteer hours. I find weak support for a sequential time allocation model of volunteering where the wage as the opportunity cost of time has only a second-order effect on volunteer hours. Increased hours of market work for married women decrease their volunteering. Cash and time donations are complements at the volunteer participation level but substitutes in terms of married women's volunteer hours.     

Household and market production of families in a late nineteenth century American city

Urban families in the late nineteenth century depended upon their children as their most important source of labor income apart from the male head of house-hold. This paper explores the determinants of the labor force participation of children over 10 years old within the context of the economic theory of household and market production, using microlevel data from 1880 Philadelphia. The father's income and unemployment, the presence of the mother or father, boarders, servants, older and younger siblings, parents' literacy, and ethnicity, among other variables, are used in a probit analysis of the labor force participation of children. The results validate the economic theory of household and market production demonstrating, in particular, substitution between mothers and their daughters and the role of comparative advantage in family decisions concerning the allocation of their members' time. Ethnic differences were only important for daughters.     

Job tasks and wages in the Japanese labor market: Evidence from wage functions

Based on the microdata from the Basic Survey on Wage Structure and the original survey, we estimate the Mincerian wage function, incorporating job tasks, to examine the importance of job task wage premiums as well as long-term changes in the Japanese labor market. In the estimation, we found that the association between abstract tasks and wages is positive and that a one standard deviation increase in the abstract task scores was associated with a 21.2% wage premium, while that of routine and manual task wage premiums are negative. We also found that the total explanatory power of three task scores (routine, abstract, and manual tasks) is higher than that of the education dummies or the major occupation group dummies. We also confirmed two testable implications from the Roy model regarding the workers’ self-selection into occupations in the Japanese labor market. These findings are similar to those obtained by Autor and Handel (2013). On the other hand, we found no major changes between 2005 and 2016 in the coefficients of routine, abstract, or manual task scores as well as their explanatory powers in the wage function. We then observed that demand for labor increased in many occupations involving many non-routine or manual tasks, but at the same time, the supply of labor to those occupations also increased. Therefore, we discussed that the change in labor demand and supply may be one of the reasons for the stable relationship between job tasks and wages.     

Women's Economic Status in Rural China: Household Contributions to Male–Female Disparities in the Wage–Labor Market

Rapid industrial growth in China coupled with economic reforms in the rural areas has created a growing demand for rural women's labor, though often at substantially lower wages than those earned by men employed in the same sector. An analysis of data collected in rural Guangdong province suggests that households may contribute to the observed male–female market wage differential through their influence in the formation of individuals' reservation wages. Under these circumstances, external employment opportunities, while no doubt serving to increase the household's overall level of income, may, on their own, be a less effective mechanism for raising the economic status of women. On the contrary, market wage signals may serve to reinforce, rather than to ameliorate, sex-based differences that arise within the household.     

Why married women's labor supply in the Netherlands has increased

Summary On the basis of cross-section data sets for 1979 and 1987 we determine: 1) the relative contribution of changes in participation and in hours of work to the increase in married women's labor supply; 2) how much of the change in participation and hours of work is determined by changes in preferences and in budget constraints; and 3) the causes of changes in market wages and reservation wages. The increase in the average unconditional hours of work is much more due to the rise in the participation rate than to the increase in conditional hours of work. Preference changes have contributed positively to the increase in married women's labor force participation over the period 1979–1987, whereas changes in market opportunities have contributed negatively. The change in the market wage and the reservation wage can be attributed mainly to changes in the population structure of married women. Changes in the model structure contributed negatively to the change in the real market and the reservation wage. The positive effect of the change in the population structure dominates the negative effect of the model structure. Finally, participants in the labor market have a comparative wage advantage over non-participants. Non-participants are a self-selecting group with a relatively high reservation wage.We like to thank Joop Hartog, Jules Theeuwes, Isolde Woittiez and two anonymous referees for their comments on a previous draft of this paper.     

分配体制缺失与收入差距扩大——基于社会原则的分配问题研究

文章认为，收入本质上是一定分配制度的产物，它不是基于贡献原则而是基于社会原则。正因为收入体现了一个社会的分配体制和法律制度，因而收入差距的拉大实际上也反映了市场机制的不健全性以及法律制度的不公正性。因此，完善社会制度、理顺公共领域以缩小收入分配就是政府的核心职能。
