基于分位数回归分解的农民工性别工资差异研究

本文使用基于分位数回归的分解方法研究了农民工的性别工资差异.结果发现,农民工的性别工资差异表现为"天花板效应";但在工资分布的最高端,性别工资差异又开始缩小.对此,本文给出了基于统计歧视和社会保护政策的解释.而城镇职工的性别工资差异则表现为"粘地板效应".在农民工工资分布的高端,性别差异表现出与城镇职工工资分布低端相似的趋势.这一点表明在工资分布高端的女性农民工已经开始突破二元分割体制,获得了一定程度的社会保护.     

建立农民工与城镇下岗职工统一的劳动力市场

本讨论了农民工进城与城镇职工下岗这两种并存的社会现象，认为城镇职工下岗与农民工进城没有必然和联系。章分析了政府为解决城镇职工下岗问题而实施的“腾笼换鸟”政策。提出应从全国一盘棋的角度，协调城乡就业关系，建立城乡统一的劳动力市场。     

国际贸易对性别工资差距的影响:基于CHFS数据的研究

文章构建了国际贸易影响分技能劳动力性别工资差距的理论模型,并运用2011年中国家庭金融调查数据(CHFS)进行均值回归和分位数回归。实证研究结果显示:就总体性别工资差距而言,国际贸易虽扩大了性别工资差距,但对分技能性别工资差距的影响存在差异,贸易对低技能劳动力的性别工资差距有缩小作用,对高技能劳动力的性别工资差距有扩大作用;就不同地区性别工资差距而言,国际贸易提高了沿海地区的工资水平,并有助于缓解该地区的性别工资差距,但对内陆地区工资水平的提高有不利影响;就分技能的分位数性别工资差距而言,在工资分布的不同位置上,国际贸易总是在扩大高技能劳动力的性别工资差距,同时国际贸易有缩小工资分布中的中低端低技能劳动力性别工资差距的作用,这大致印证了上述均值回归的结果。基于以上结论,在贸易促使竞争加剧的背景下,即便高技能女性有时也难以从贸易中获得和男性均等的利益,虽然改善女性的个体特征(如受教育程度)有助于缓解性别工资差距的问题,但只有政府加强对劳动力市场的监管、完善社保制度,才能为解决性别工资差距建立更有效的制度保障。     

转型劳动力市场中工资差距扩大分析

文章认为,我国劳动力市场转型主要是工资结构的调整以及人们在不同就业状态上的分化。劳动力市场改革也使得工资差距不合理的扩大。劳动力市场中收入分配失序的原因有国家规制、非价格机制和劳动力市场分割等。如果我国在构建和谐社会的过程中,采取新的发展战略,重构劳动力市场改革,那么,将不仅有利于经济效率的改善,也有利于收入分配更为平等。     

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。     

中国的工资性别差距及其分解——性别歧视在多大程度上存在?

本文运用中国健康与营养调查(CHNS)2006年的数据对劳动者的工资性别差距进行测度和分解,研究发现在控制个人特征和单位特征后,男性劳动者的小时收入比女性劳动者高23.8%,考虑就业选择偏差后的工资性别差距更大一些,达25.2%。由于劳动者特征差异形成的工资差异很小,而且往往是女性由于个人特征占优而有助于缩小差距。差异的更大部分是由收益率差异造成的,这在一定程度上反映了性别歧视的存在。主要表现在工龄方面受到歧视,女性的工龄收益率低或者为负值。进一步考虑选择性偏差和找到工作概率进行分解的结果说明,女性在就业获得方面受到歧视,这会严重影响其与男性劳动者的收入差距。     

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。     

心理资本对农民工与城镇职工工资差异的影响——来自浙江省的调查数据

本文基于浙江省职工调查的微观数据,通过分位数分解法对农民工和城镇职工工资收入差异进行了分解,重点研究了心理资本对农民工和城镇职工工资差距的影响程度。分解结果显示,心理资本对农民工和城镇职工工资差异的贡献基本随着分位数的提高而上升。在各个分位点上,心理资本对系数差异的影响程度都超过了对特征差异的影响度。     

城镇就业市场上劳动力工资扭曲程度测度

本文利用CHIPS2007数据库,基于随机前沿模型对我国城镇就业市场上劳动力的工资扭曲程度进行测度。研究结果表明：（1）在城镇就业市场上,由于工资扭曲现象的存在,劳动力实际获得的工资要比他们的边际生产率低45％～60％;（2）已婚、子女个数较少、本地、拥有失业保险、男性、大中型企业的劳动力工资扭曲程度要低于未婚、子女个数较多、外来、没有失业保险、女性、小型企业的劳动力;（3）中低工资水平的劳动力工资扭曲程度要比高工资水平的劳动力严重,且中低工资水平劳动力工资扭曲程度的方差更大。由此,本文提出推进就业市场的市场化改革,完善就业市场信息网络,从而减轻劳动力工资扭曲程度。     

数字经济背景下互联网的使用对民营企业员工性别工资差距的影响——基于员工受教育层次差异化特征的分析

基于2017年中国综合社会调查的民营企业员工数据,使用稳健最小二乘回归与Oaxaca分解法研究发现:互联网的使用将对未接受过教育以及仅接受过私塾扫盲班/小学教育的民营企业员工工资产生显著的负向影响;互联网的使用将对接受过初中及以上教育的民营企业员工工资产生显著的正向影响;随着民营企业员工受教育水平的提升,互联网的使用对民营企业女性员工工资的弹性影响远超男性;互联网的使用将扩大未接受过教育的民营企业女性员工与男性员工的工资差距;互联网的使用将缩小接受过私塾扫盲班/小学及以上教育的民营企业女性员工与男性员工的工资差距。据此提出,应加大公益互联网使用培训力度,以提升女性的互联网理性使用水平、加强清扫虚假网络平台以防止受教育层次较低女性误入歧途、鼓励女性自主接受多元化再教育以提升自身互联网理性使用水平等,以缩小民营企业员工性别工资差距。     

Minimum Wage Regulation in China and Its Applications to Migrant Workers in the Urban Labor Market

Using data at micro and city levels, the present paper explores the policy evolution of the minimum wage system in China, and examines its coverage for migrant workers. The analysis indicates that minimum wage policy has been substantially improved in terms of both coverage and the level of the minimum wage standard, but that the current policy tool that relies on the monthly wage rate is not effective. Because migrant workers tend to work more hours, use of an hourly wage rate is more appropriate than a monthly wage rate.     

Occupational Segregation and its Effect on Estimates of the Gender Wage Differential: Evidence from Brunei

This paper investigates the impact of the different occupational distributions of the gender groups on the gender wage differential in Brunei. We disaggregate occupational differences into explained and unexplained portions as this can provide better estimates of across-occupation and within-occupation wage differentials. Using data from the Brunei 1995 Labor Force Survey report, results indicated that the gender wage difference is approximately 60%. Unlike other studies, it is found that in Brunei the unexplained portion of occupational segregation has had an impact on gender wage differentials and accounts for approximately one-third of the observed gap. Interestingly, the unexplained component of the within-occupation gap is relatively less than in some developed economies. This is attributed to the effects of the large public sector in Brunei and its regulated pay scales.     

Gender Discrimination and Worker Selectivity: A Comparison of the Self-employed and Wage Earners

This study compares the size and nature of the gender earnings differentials for the self-employed and wage earners in Korea, taking into account the workers’ self-selection of each employment type. The two-stage estimates of the earnings equation, corrected for worker selectivity, are used to decompose the gender earnings differentials into productivity-related and discriminatory factors. Our results suggest that the size of the gender earnings gap is larger in the wage sector than in the self-employment sector, but not by large margin, and so is the discrimination effect when not controlled for worker selectivity. With worker selectivity controlled, the discrimination effect is greatly intensified in the wage sector, while it becomes not significant in the self-employment sector. These findings imply that the observed gender earnings gap in the wage sector is largely ascribed to discrimination against women, while the gender earnings gap in the self-employment sector is mostly due to productivity difference that, in part, is caused by worker selectivity.     

最低工资制度对劳动力市场影响的实证分析

本文对最低工资理论模型进行了拓展分析,并以深圳为案例分析了最低工资制度对区域就业的影响。在跨区域劳动力流动的情况下,区域劳动力市场均衡工资趋近最低工资标准,并且不会导致区域就业量的下降。     

上海市最低工资标准的合理性——基于最低工资收入者角度的实证分析

最低工资制度是世界各国普遍采用的劳动保障制度,其目的在于维护劳动者取得劳动报酬的合法权利,保障劳动者尤其是低收入劳动者及其家庭成员的基本生活。文章依据相关法规政策规定的最低工资标准制定时需要考虑的因素,从保障低收入劳动者基本生活需要的角度,应用统计性描述方法对1993-2012年上海市最低工资与职工平均工资、人均GDP、最低社会保障线、人均消费性支出等进行分析。分析结果发现上海市最低工资与职工月平均工资的比远低于40%~60%的国际标准,与人均GDP的比值低于全国平均水平,表明上海市最低工资标准偏低,需要进一步改进或完善相关政策。     

Gender Effect in Explaining Mobility Patterns in the Labor Market: A Case Study of Turkey

This paper examines the importance of gender for different job mobility patterns using an extensive household survey data from İzmir, the third largest city in Turkey. The determinants of job‐to‐job and job‐to‐nonemployment transitions are analyzed with the help of a multinomial logit estimation method. The results indicate that there is a distinction regarding the probability of job mobility patterns based on gender. It is more likely for women to be engaged in job‐to‐nonemployment transition, whereas men tend to change jobs more often. Although gender plays a significant role in job mobility patterns, traditionally imposed social constraints associated with childcare and household duties provide us with mixed results considering the behavior of women in the job market. On the other hand, having highly paid and secure jobs decreases the probability of both patterns of job mobility.     

Gender Difference in Returns to Education Independent of Gender Wage Gap in Korea*

This study examined the difference between male and female groups’ return on investment (ROI) in education independent of the average gender wage gap. Women’s additional ROI in education was significant and positively estimated. Furthermore, the ROI in women’s education was consistently higher than that in men regardless of educational stage, except for graduate education. These gender differences were greater in the younger generation than in the older generation and have decreased significantly in the recent ten years in high school education. Although the additional ROI in women’s education was positive in the field of culture and arts, education’s effect on wage increases in professional occupations was less than in men, especially in the fields of law and medicine. In addition, we show that gender differences in ROI in education were countercyclical. A base effect, large wage declines for low‐educated women during recessions, could explain this phenomenon. However, coinciding with the existence of positive cash flow news in the stock market that promises good business performance, a significant wage increase among highly educated women was found.
