国有部门与非国有部门工资差异及人力资本贡献

本文利用微观调查数据,对我国国有部门与非国有部门的工资差异进行了实证研究。在对工资差异进行分解后,本文发现,我国国有部门的工资优势中有80%以上来自于人力资本的优势,这说明人力资本在国有部门的工资决定中已经发挥了决定性作用。但人力资本对工资差异的贡献在工资分布区间并不均匀,它随着工资从高分位点到低分位点逐渐降低,与此对应的是工资溢价随工资从高分位点到低分位点逐渐升高。从工资差异看,在工资分布的高端——高知识高技能人才的密集区,工资差异完全体现为人力资本的差异,而在工资分布的低端——低技能劳动力的密集区,工资差异有很大一部分是人力资本无法解释的,也即溢价。本研究认为,造成这种现象的原因在于国有部门"共享式"的工资决定模式。这种模式倾向于在压低高技能劳动力的报酬率的同时,抬高低技能劳动力的报酬率。所以国有部门的工资决定应进一步强化人力资本的报酬机制,以提高效率,增强竞争力。     

最低工资与已婚女性劳动参与

借助中国家庭金融调查2011—2013年数据,以及最低工资标准在不同区县不同时间上的差异,在分别考察最低工资标准上涨对工资、就业的影响后,本文重点考察了最低工资标准上涨对劳动参与,尤其是已婚女性劳动参与的影响。回归结果显示:(1)最低工资标准上涨10%,员工的雇佣工资显著增加6.6%,被雇佣概率下1.2%,但在10%的统计水平下不显著。(2)最低工资标准上涨主要增加已婚女性的劳动参与率。最低工资标准每上涨10%,已婚女性劳动参与率显著增加1.86个百分点,且以从事非农工作为主。对工资收入处于最低25%的已婚女性,劳动参与率更是显著增加3.03个百分点。(3)综合考察最低工资标准上涨对已婚女性劳动参与以及进入劳动市场后就业概率的影响发现,最低工资标准上涨10%,16—55岁已婚女性中就业个体的占比显著增加2个百分点。(4)从异质性上看,最低工资标准上涨主要影响中年、低教育水平或来自西部地区的已婚女性。在劳动供需发生根本转变的情形下,通过激活劳动力存量,上调区县最低工资标准对短期内缩小中国劳动力供需缺口有重要作用。     

Decomposing Gender Wage Differentials Using Quantile Regression: Evidence from the Lebanese Banking Sector

This paper investigates gender pay inequality in the labor market of a developing country. Our empirical investigation uses data derived from a sample of employees in the Lebanese banking sector for the years 2008 and 2014. Using Blinder-Oaxaca decomposition, the results reveal that the unexplained component of the gender wage gap, attributed to discrimination, represents a substantial share of the total gap. A surprising result is that the contribution of human capital to the gender wage gap is negative, suggesting that wage discrimination is the main explanation for the gap. Utilizing the Machado-Mata methodology to decompose the wage gap across the entire wage distribution, our findings indicate that the unexplained component of the raw gender wage gap is more pronounced at the low and middle ranges of the distribution. However, the explained component dominates at the top of the distribution, suggesting that earnings gaps are fully explained by observed characteristics.     

A Cross-Section Analysis of the Labour Force Participation of Married Women in Australia

'In a time when whales and seals are classified as endangered species, babies also seem to be an endangered species ˙˙˙ with so many mothers in the workforce our population growth has dropped below zero and I think the Federal government should counter that trend˙˙˙˙ Babies born in Australia are our best new Australians.' (Senator Florence Bjelke-Petersen in a speech to the Women's Action Alliance, reported in the Canberra Times, 3 June 1981 .)
The paper examines the labour supply of married women in Australia using data from the 1974 Census of Population and Housing. A number of approaches to modeling are employed. In the first instance OLS equations are estimated. These estimates are compared with instrumental variable estimates endogenizing wage rates. and with estimates from a three-equation system endogenizing fertility as well as wages. The evidence suggests that many of the factors proposed by modern theory do exercise significant influences in anticipated directions on the labour supply of married women in Australia.     

The Effect of Work Experience on Female Wages and Labour Supply

This paper develops and implements a semiparametric estimator for investigating, with panel data, the importance of human capital and time nonseparable preferences to females when aggregate shocks are present. It provides a set of conditions for making statistical inferences about agents' expectations of their correlated future choices, from a short panel. Under the assumption that observed allocations are Pareto optimal, a dynamic model of female labour supply and participation is estimated, in which experience on the job raises future wages, and time spent off the job in the past directly affects current utility (or, indirectly through productivity in the no-market sector).     

Wage Differentials between the State and Private Sectors in Moscow

In this study the 1997 Russian Labor Force Survey is used to investigate wage differentials between the state and the private sector in the city of Moscow. Our analysis demonstrates that substantial differences exist between private and state sector wages. We estimate the gap between private and state sector wages to be 14.3 percent for men and 18.3 percent for women. We also find gender differences in wages. Men in the private sector earn on average 23.7 percent more than women. The gender wage gap in the state sector is even higher at 32.5 percent. In the state sector, wages for both men and women increase as years of tenure increase. But in the private sector this is only true for men; women earn no return to tenure. The probability of employment in the private sector decreases with age and tenure.     

Analysis of the 1980 Sydney Survey of Work Patterns of Married Women: Further Results*

Using cross-section data from the 1980 Sydney survey of the work patterns of married women, this paper contributes to the very scarce Australian stock of disaggregate econometric studies of the labour market activities of married women. Labour force participation, hours of work and wage functions (reservation wage as well as market wage) are estimated in a second-generation static labour supply framework. Unique features of the study include the availability of direct data on previous market experience, a formulation of the impact of children on the participation decision which permits testing for the presence of economies of scale in child-minding activities, estimation of the reservation wage function, and a data base which permits a clear distinction between earnings and other forms of income.     

不同期限类型劳动合同的工资决定机制及差异——基于中国家庭住户收入调查数据的经验研究

文章利用2002年住户收入调查(CHIP)数据对我国不同期限类型劳动合同的工资决定机制及工资差异进行了经验研究。结果发现,长期劳动合同与短期劳动合同的工资差异符合补偿性工资差别理论,企业对没有签订劳动合同的员工存在工资歧视。排除特征因素和选择性因素,长期劳动合同工的工资比短期劳动合同工低42.84%,比无劳动合同员工高29.6%。文章研究表明:短期劳动合同没有对生产率表现出显著的负面影响,提升劳动合同签订率是比限制短期劳动合同使用更为合适的劳动政策。     

A Reexamination of the Time Path of Wage Differentials in Taiwan

Contrary to the conclusions of a recent paper by Chen and Hsu (Review of Development Economics, vol. 5, 2001, pp. 336–54), wage inequality and returns to college‐educated workers have risen in Taiwan since 1980. Government policies which have caused rapid expansion of the supply of new college graduates have depressed returns for only the youngest cohorts of college graduates. Older cohorts of college graduates experienced rising returns, as have college graduates as a whole. Young college‐educated women's returns fell more and older college‐educated women's returns rose more relative to their male counterparts. Consequently, the rising share of women in the labor force helped amplify these trends. Changing trade patterns have tended to increase labor demand in sectors that use educated labor more intensively, helping to raise returns to skill. However, in contrast to western economies, rising capital intensity does not appear to have accelerated the pay gap by skill in Taiwan.     

Efficiency-Wage Unemployment and Intersectoral Wage Differentials in a Heckscher–Ohlin Model

The paper analyzes a Heckscher–Ohlin (HO) model with efficiency-wage unemployment (henceforth HOe model). We show that all HO results have close HOe analogues. Additionally, conditions are derived under which immigrants might not only find employment for themselves but also raise employment for natives. Moreover, we analyze the ranking of countries with respect to their rate of unemployment, showing that this ranking may be reversed as countries move from autarky to trade. All results are clearly linked to factor intensities and the pattern of intersectoral wage differentials.     

Labour Utilization and Wage Inflation in Australia: An Empirical Examination*

This paper tests the hypothesis that the level of labour utilization within the firm should be substituted into the Phillips Curve in place of traditional measures of excess demand. Gregory and Smith (1983) proposed overtime hours as a proxy for labour utilization within the firm. For various reasons we prefer the deviation from trend in hours worked. The results support the underlying hypothesis, and add strength to the view that to understand the process of wage inflation at the macro level we must examine the utilization of labour at the micro level of the firm.     

Collective Labour Supply: Heterogeneity and Non-Participation

We present identification and estimation results for the "collective" model of labour supply in which there are discrete choices, censoring of hours, and non-participation in employment. We derive the collective restrictions on labour supply functions and contrast them with restrictions implied by the usual "unitary" framework. Using the large changes in the wage structure between men and women in the U.K. over the last two decades, we estimate a collective labour supply model for married couples without children. The estimates of the sharing rule show that male wages and employment have a strong influence on bargaining power within couples.     

Wage Adjustments and Labour Market Systems: A Cross-Country Analysis*

Evidence is presented on how well alternative systems of wage determination facilitate disaggregate labour market adjustment. Tests of statistical causality are used to relate labour market pressure to relative wage changes. The conclusion is that rates of change of relative wages are determined independently of the microeconomic market balance. This result holds irrespective of the institutional form of the wage-fixing system.     

工作特征对性别工资差距的作用

补偿性工资是解释性别工资差距的理论之一。本文利用2006年中国综合社会调查(CGSS2006)数据同时考察了人力资本和工作特征的工资效应,并采用Jann(2008)提出的无歧视工资机制的估计方法,对性别工资差距进行了分解分析。研究发现,我国城镇劳动力市场两性的工作特征存在显著的差异,但部分工作特征对工资的作用方向并不符合补偿性工资理论的预期。管理职务上的差异对性别工资差距具有一定的解释作用,但加入大量的工作特征变量后,性别工资差距中总的可解释部分没有明显提高。由此推论,性别歧视可能是形成工资差距的重要因素。促进性别平等和妇女发展必须采取更加积极的公共政策和反歧视措施。     

Flexible Hours,Workplace Authority,and Compensating Wage Differentials in the US

The theory of compensating differentials suggests that workers with flexible schedules will earn less than other workers. Some authors have also contended that the concentration of women in jobs with flexible hours explains a significant part of the gender pay gap. This paper uses data from the US subset of the Comparative Project in Class Analysis to test these hypotheses. These data first indicate that, contrary to popular wisdom, women workers do not have more flexible schedules than men. Second, the really striking differential is by race: black workers have much more rigid schedules than white workers. Third, workers with more authority at the workplace typically have more flexibility than subordinate workers. Finally, the data show that any compensating differentials for flexible hours are small and are offset by returns to workplace authority.     

公共部门与非公共部门收入差异的变迁

基于社会阶层动态演化理论,本文提出了部门收入差异阶段性假说。随后利用CHNS面板数据实证检验了该假说。结果表明,第一阶段(1989—1997年),在较高的收入层次上,非公共部门比公共部门具有明显的收入优势,并且这一收入优势随着收入水平的提高而提高。非公共部门的教育回报率也更高;第二阶段(2000—2009年),在中低收入分位数上,公共部门比非公共部门表现出明显的收入优势。在较高的收入分位数上,非公共部门不再具有收入优势。在较高的教育水平上,两大部门的教育回报率接近。同时,两个阶段中在较低和较高收入分位数上表现出的部门收入差异主要源自部门特征因素。实证研究支持了阶段性假说,为我国收入分配结构性调整提供了启示。     

Fiscal Institutions and Wage Bargaining in the Local Public Sector

In a theoretical analysis of the properties of different wage setting and financing systems in the local public sector, two financing systems are considered. A benchmark model with local financing through local taxes is compared with a system of centralized financing through grants, where taxes are decided at the national level. It is shown that the wage outcomes under centralized financing depend heavily on the order of moves in the budgetary game between the central and local levels.

Gender Wage Differentials and Occupational Segregation in Hong Kong, 1981–1996

This paper analyses gender wage differentials and the role of occupational segregation in Hong Kong. It is found that the female–male earnings ratio increased substantially from 0.710 in 1981 to 0.839 in 1996. A decomposition which takes into account occupational differences shows that the gender pay gap is mostly within occupations and most of the intra‐occupation wage gap is unexplained. The gender pay differential due to occupational differences is small; in fact, the overall occupational segregation favours females in Hong Kong.     

Social Security Earnings Test and the Labour Supply of the Elderly: New Evidence from Unique Survey Responses in Japan

This study proposes an alternative approach of utilizing direct responses to a survey on the social security earnings test for the elderly to provide new evidence on the sensitivity of the labour supply decision of workers aged between 60 and 64 with respect to the test. Our empirical results show a discouraging effect on working in a large proportion of these workers in Japan, even after correcting for the observed attributes of individuals who reported being either affected or unaffected.     

Institutionalist Theories of the Wage Bargain: Beyond Demand and Supply

I distill an integrated structure of institutionalist theories of wage determination, linked by overarching views of reality and key principles, and show that three fundamental propositions connect these into one “extended family.” I then outline ten principles that reflect the models and propositions. While very different in form than the familiar Walrasian price-auction model, this relatively succinct approach to wage determination leads to many testable hypotheses. It also explains questions, such as: Why can the minimum wage not often be raised without causing unemployment? Why has wage inequality increased within occupations and educational levels, as well as between? Why does high pay tend to be accompanied by better benefits, working conditions, and on-the-job training (rather than compensating for the lack of one of these)? The insights of many contemporary institutional economists, including Robert Prasch, are particularly important to this analysis, along with earlier work of John R. Commons, John Dunlop, Lloyd Reynolds, and Lester Thurow.
