国内外工资差别研究述评

工资差别按照形成原因可归结为两种:市场性工资差别和非市场性工资差别。前者包括人力资本补偿性工资差别以及行业工资差别,后者包括歧视性工资差别和制度性工资差别。本文通过总结国内外这几类工资差别的研究进展情况,得出结论:我国的竞争性工资差别小于其他国家,由劳动力市场分割导致的垄断性工资差别是我国工资差别的主要形成原因。调节工资差别的关键是培育其市场形成机制。     

Parenthood and the gender wage gap in urban China

Using data from the Chinese Household Income Project survey and decomposition methods, this study explored the influence of parenthood on the gender wage gap in urban China in 2002 and 2018. Our findings showed that the employment rate is lower for women than men in both childless and with child groups, and the gender gap expanded from 2002 to 2018. The data revealed a parenthood wage penalty in 2002 and a parenthood wage premium in 2018. Moreover, the parenthood wage penalty was greater for women than for men and contributed to the formation of the gender wage gap. We also found that three components: motherhood wage penalty, fatherhood wage premium, and gender wage gap in the childless group contributed to the formation of the gender wage gap. From 2002–2018, the motherhood wage penalty decreased, whereas the fatherhood wage premium increased.     

Minimum Wages,On-the-Job Training,and Wage Growth

Using data from the Employment Opportunities Pilot Project, we examine the relationships between minimum wages, wage growth, and on-the-job training. We find that minimum wage jobs exhibit less wage growth than other jobs, particularly for men. We find no evidence, however, of a unique minimum wage effect on training opportunities. We conclude that indirect methods of proxying training with wage growth can be misleading as they fail to distinguish whether the reduced wage growth of workers on minimum wage jobs results from their receiving less training than other workers or whether it is strictly a result of the wage determination process.     

A distributional analysis of union-wage effects in South Africa: Evidence from panel data

This paper examines whether individual workers’ time-invariant unobservable characteristics influence estimates of the South African union wage premium across the length of the conditional wage distribution. It employs the 2001–7 South African Labour Force survey and a fixed effects quantile regression estimator. Results show a relatively large (small) wage premium at the bottom (top) of the conditional wage distribution when workers’ time-invariant unobserved characteristics are ignored. Accounting for this set of factors substantially reduces the wage premium at all points of the distribution. In fact, the wage premium becomes somewhat constant across the conditional wage distribution, suggesting that unions in South Africa have little wage compressionary effects.     

最低工资制度的执行力度和影响因素研究——以农村转移劳动力为例

文章利用2011年浙江省杭州市最低工资标准调整的契机,调查分析了新的工资标准实施前后最低工资制度在农村转移劳动力中的执行力度及其影响因素。研究发现,工资标准的提高使农村转移劳动力的最低工资标准执行力度由原先的80%降低到70%左右;最低工资制度在提升劳动者收入上发挥了一些效果。研究显示,企业性质、企业规模和企业所处的地理位置均是影响最低工资制度执行力度的因素;劳动者的人力资本水平也是影响执行力度的重要因素。文章认为,当前的最低工资制度存在着工资标准过低和执行力度不足的问题,大幅度削弱了该政策提升劳动者工资的作用。     

美国最低工资制度的发展及启示

美国最低工资有联邦与州之分。由于适用普遍性与合理工资水平之间的内在紧张难以消除,最低工资呈向下发展趋势。为了补足最低工资的低水平,20世纪90年代,一些地方政府启动了生活工资立法,形成新的最低工资形式。我国最低工资实施的背景与美国有相似之处,可考虑借鉴其经验,构建多元最低工资结构,这种多元结构应建立在劳动者"参与中心型"的立法机制之上。     

An Investigation of the Female–Male Wage Gap During the Industrial Revolution in Britain

During the industrial revolution women's wages were substantially lower than men's. This article documents the wage gap and shows that in most cases it can be explained without reference to wage discrimination. First, the wage data we have overestimate the wage gap; correcting for biases due to measurement error reduces the size of the wage gap. Second, because differences in productivity were substantial, the corrected wage gap is consistent with these.     

How skilled were English agricultural labourers in the early nineteenth century?1

Using the wage accounts of two different farms in the 1830s and 1840s, matched with census records to determine the age of the workers, this article estimates age‐wage profiles for male and female agricultural labourers. Females earned less than males, and had less wage growth over their life cycles. Male wage profiles peaked at age 30–5, earlier than the wage profiles of workers today. Before the age of 30 wage growth was more rapid than increases in strength, but less rapid than wage growth among factory workers. If wage increases after the age of 20 indicate skill acquisition, then male agricultural labourers acquired a significant amount of skill, but less skill than contemporaneous factory workers.     

Do Wages Continue Increasing at Older Ages? Evidence on the Wage Cushion in the Netherlands

In this study, we investigate the anatomy of older workers’ wages. The central question is whether the wage cushion—i.e., the difference between actual wages and collectively agreed-upon (maximum) contractual wages—contributes to the fact that wages continue increasing at older ages. We follow the wages of individual workers in twenty-two sectors of industry in the Netherlands using administrative data for the period 2006–2010. In the public sector, we find no evidence of a wage cushion. Wage scale ceilings set in collective agreements are guiding for older workers’ wages, and workers earning a contractual wage equal to a wage scale ceiling are not compensated with higher additional wages. In the private sector, we do find evidence of a wage cushion. Wage scale ceilings are less restrictive and workers earning a contractual wage exceeding the highest wage scale ceiling experience higher contractual wage growth. The private sector wage cushion enhances wage differentiation and allows for wages that continue increasing at older ages.     

Rigid wages or small equilibrium adjustments? Evidence from the contraction of 1893

Contrary to the conclusions drawn from some macroeconomic studies, U.S. labor markets could exhibit considerable cyclical wage rigidity even before World War I. Using disaggregated data from Cincinnati manufacturing firms during the 1893 contraction, I estimate a threshold or friction model of wage adjustment that distinguishes between impediments to wage cuts and wage cuts that were small but possibly market clearing. The wage adjustment process exhibited friction which was both statistically and economically significant and which varied with establishment size, capital intensity, and payment method. Worker resistance to wage cuts was a factor contributing to this pattern of wage rigidity.     

The Wage and Employment Dynamics of Minimum Wage Workers

This study uses panel data to examine the wage and employment dynamics of minimum wage workers. Compared with workers earning above the minimum, minimum wage workers are much more likely to be new entrants or to exit the labor market. Changes in industry, occupation, and access to job training are particularly important to improving the wages of minimum wage workers. Many minimum wage workers earn less than their potential wage temporarily because of nonwork circumstances that make higher-paying jobs less attractive.     

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.     

Occupational Segregation and Gender Wage Differentials: Evidence from Malaysia

In Malaysia, the participation of women in the labor market has increased over time. However, occupational segregation and wage differentials continue to be prevalent between men and women in the labor market. The present paper investigates gender‐related occupational segregation and wage differentials based on data collected from 7135 working households in Peninsular Malaysia in 2011. The wage decomposition model introduced by Brown et al. (1980) is used to examine the determinants of gender‐related wage differentials. The results suggest that differences within occupations account for the largest portion of the wage gap between men and women. The results also indicate that wage discrimination within occupations plays an important role in the gender wage gap, while sample selection bias plays an important role in the examination of gender wage gaps.     

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。     

Foreign Takeovers and Wages in Hungary

This study investigates the wage premium that foreign takeover firms pay for a type of worker on top of the wage before takeover. We apply Hungarian employee-employer matched data from 1992 until 2001, and find a nonlinear wage premium profile before and after a foreign takeover. Takeover targets do not pursue a different wage policy before ownership change compared to other indigenous firms. Then, there is a hike in the wage premium during the takeover year. Moreover, there is gradually building up a wage premium over the following years after the takeover. The later stylized fact helps discriminating bargaining theories of the foreign-investor wage premium from technology spillover theories. JEL no. E24, F16, F23     

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.     

STATE-LEVEL BASIC WAGES IN AUSTRALIA DURING THE DEPRESSION, 1929–35: INSTITUTIONS AND POLITICS OVER MARKETS

State wage-fixation tribunals developed quite particular patterns of basic wage fixation during the Depression. They declined to follow the Commonwealth Court's 10 per cent wage cut, thereby confining its effect to about half the workforce and creating distinctly different State and Commonwealth basic wage patterns in each capital city. Further, tribunals' uneven patterns of basic wage adjustment to deflation meant that in some states, the real State basic wage increased. Patterns of state institutional behaviour and state politics therefore help explain the stickiness of real average wage levels during the Depression.     

From Phillips curve to wage curve

Summary In most traditional macroeconomic models for The Netherlands the wage equation is specified by a Phillips curve, in which wage growth is negatively related to the unemployment rate. This paper shows, however, that wage formation can better be described by the so-called wage curve, in which the wage level, instead of wage growth, depends negatively on the unemployment rate.The author thanks S.K. Kuipers and D.A.G. Draper and other colleagues of the Central Planning Bureau for their useful comments.     

Trade,technology, and the labour market: impacts on wage inequality within countries

This paper focuses on the widening wage inequality between skilled and unskilled workers within countries and discusses whether trade and technology have contributed to this trend. The paper develops an analytical framework for wage inequality that traces the determinants and their relative roles in wage inequality in different stages of the development of trade theory, especially those considering new evidence after 2011. We find that technology plays a key role in the rise of wage inequality in most countries, while trade plays an increasingly crucial and more complex role in recent years. Skill supply institutions, such as education systems supplying skilled labour or unions participating in wage‐setting processes, suppress the rise of wage inequality in some countries. The paper further outlines the mechanisms through which trade affects wage inequality, including offshoring, firm heterogeneity, labour market frictions and global value chains. We find that trade has indirect effects on technology, which further enlarges the wage inequality among skills. The paper also discusses the policy implications of the impacts of trade and technology on wage inequality.     

Real Wages in Australia and Canada, 1870–1913: Globalization versus Productivity

Australia's and Canada's real wage experiences between 1870 and 1913 were distinctive. Faster productivity growth underpinned Canada's overtaking of Australia's wage levels. The globalization forces of migration and trade also shaped their comparative wages, principally by reducing wage growth in Canada. Immigration increased slightly Australia's real wages, but reduced wage levels in Canada, and tempered there the beneficial effects of rising productivity and improving terms of trade. In contrast, wage earners' share of national income rose after 1890 in Australia, with the productivity slowdown hitting chiefly rents and profits. Distributional shifts favouring wage earners in Australia, and the depressing effects of mass immigration on wages in Canada, limited Canada's wage lead before 1914, despite her faster productivity growth.
