市场歧视对城镇地区性别工资差距的影响

本文使用基于分位数回归的反事实分析方法研究了中国城镇地区的性别工资差距问题,发现了以下三个结论:第一,性别工资差距在工资分布不同位置上存在不对称现象。从横截面数据来看,在工资分布顶端性别工资差距较小,在工资分布末端性别工资差距较大。从时序数据来看,在工资分布顶端性别工资差距越来越小,在工资分布末端性别工资差距越来越大。第二,性别工资差距在横截面数据上表现出不对称现象的原因是,女性在工资分布顶端受到的歧视程度低,在末端受到的歧视程度高。第三,性别工资差距在工资分布末端越来越大的原因是,女性受到的歧视程度越来越高;在工资分布顶端越来越小的原因是,男性和女性个人特征方面(如受教育水平)的差别越来越小。     

劳动工资理论的误区及其矫正

劳动要素所得过低是导致我国收入分配差距过大的重要因素.所谓劳动力成本低廉的竞争优势,在很大程度上是挤压了劳动者合理的生存工资、生活条件和最基本的社会保障而形成的.这是新古典经济学市场竞争决定收入分配从而决定雇佣环境带来的后果,走出这一误区就需要在认识这些理论缺陷的同时补上遗漏的工资理论信息,为改变劳动报酬偏低的收入分配格局提供理论支撑和政策导向.     

中国城市劳动力市场上的性别工资差异

本文描述了中国城市劳动力市场上男女在行业获得和工资上的差异,并且用计量方法对工资差异进行了分解。分解结果表明,男女工资差异主要由同类行业内工资差异引起,而由于两者行业分布不同而带来的工资差异不大;歧视是造成性别之间的工资差异的主要原因,人力资本所起的作用很小。由此,缩小行业内的工资差异,消除对女性的歧视,是缩小工资性别差异的重要途径。     

Wages and Wage-Bargaining Institutions in the EMU – A Survey of the Issues

The paper distinguishes between the impact of the EMU on nominal wage flexibility and on equilibrium real wage and unemployment levels. A perceived need to increase nominal wage flexibility as a substitute for domestic monetary policy and a tendency to less real wage moderation in the EMU are likely to promote informal bargaining coordination and social pacts in the medium run. But such coordination is not likely to be sustainable in the long run, as it conflicts with other forces working in the direction of decentralization and deunionization. This could lead to more government intervention in wage setting during a transitional period. Although monetary unification will strengthen the incentives for higher-level transnational coordination of wage bargaining, such a development is improbable in view of the coordination costs involved. If transnational coordination develops, it is most likely to occur within multinational firms.     

Wage Indexation, Employment and Inflation

Price versus productivity-indexing is considered in a model of monetary policy with incomplete information and wage bargaining. In a perfectly price-indexed economy, the inflationary bias due to lack of credibility is eliminated. However, productivity-indexing is more appropriate to dampen macroeconomic fluctuations that are caused by real disturbances. We show that productivity-indexing alone guarantees both price and employment stability, provided the government's reputation is good enough and the union's bargaining power is not too strong. This reduces the degree of price indexation as the union becomes weaker and the government's reputation improves. Productivity-indexing is desirable with volatile productivity processes and weak unions.

Parasitic-Industries Analysis and Arguments for a Living Wage for Women in the Early Twentieth-Century United States

This paper examines arguments by activists and economists surrounding attempts to establish minimum wages for women in the United States in the Progressive Era. In particular, the paper focuses on analyses based on Beatrice and SidneyWebbs' argument that industries paying less than a living wage were "parasitic" on the society, a net drain on macro-efficiency. This analysis, widely accepted among economists of the time, viewed women as particularly vulnerable workers facing labor markets that were institutionally constructed and predatory. Unequal gender roles, employer power, and the absence of collective bargaining could all result in wages that were socially unacceptable as well as economically nonoptimal. These debates offer insights for modern feminist wage theories, and for current living wage campaigns.     

Progressive Taxation and Wage Setting: Some Evidence for Denmark

The proposition that a progressive tax system contributes to wage moderation is studied using Danish earnings data disaggregated by occupation, gender and earnings level. Our main conclusions are that income-tax progression affects wage setting, but whether it moderates or exaggerates wage pressure is income dependent. An increase in progressivity reduces the pre-tax earnings of middle-income workers (manual male workers and moderate income earners among both male and female non-manual workers). The reverse is found for high-income earners (non-manual male workers), in that an increase in progressivity tends to raise pre-tax earnings. Finally, there is no significant effect of tax progressivity on the wages of low-income earners.

Changes in the Finnish Wage Structure: Will Demand and Supply Do?

This study addresses changes in the wage structure in Finland between 1977 and 1995, and provides a simple explanation based on the demand for and supply of skills. The single index model of Card and Lemieux (1996) is augmented by incorporating changes in the supply of skills. The augmented model adequately accounts for the changes in relative wages between groups of different education and experience, but does not capture the changes in the within-group distribution.

薪酬改革效果的定量评估

薪酬制度不但是公司的价值分配系统,而且是管理劳动力的有效手段。随着公司的发展,不可避免地要对薪酬体系进行变革。目前,大多数企业对薪酬改革的评估仍然停留在主观层面。至于薪酬改革对企业的贡献是多少,新的薪酬制度相对旧的制度好在哪里、差在哪里以及程度如何却不甚了了。本文以H公司的薪酬改革为例,探讨了如何使用定量方法评估薪酬改革的效果。     

Wage discrimination and population composition in the long run

We derive the conditions that sign the effects of changing population composition on wage levels and ratios, when labor supply and discrimination preferences vary. The overall effect depends on an aggregate market, a relative market, and a preference distribution effect.     

Conflict, Effort and Capital Stock in UK Wage Determination

The paper is concerned with the determination of wages, unemployment and labour productivity in the UK. The theoretical model suggests that in addition to economic factors, historical and ideological elements play an important role in the determination of wages, unemployment and productivity. Particular emphasis is put on the capital shortage hypothesis. It is argued that capital scrapping in response to the two oil price shocks, combined with subsequent sluggish growth in capital, may be responsible for the rise of the NAIRU and the persistence of unemployment. The empirical analysis is concerned with testing the theoretical model, using quarterly data for the UK from 1966 until 1994. We use cointegration analysis for the determination of wages, unemployment and labour productivity. This revised version was published online in July 2006 with corrections to the Cover Date.     

中国劳动力市场名义工资粘性程度的估算

本文完成了对中国劳动力市场名义工资粘性程度的首次估算,发现中国的名义工资粘性处于世界较低水平。这具有重要的宏观政策含义:一方面表明中国的劳动力市场具有很强的"自我调节"经济波动的特性,另一方面说明中央银行扩张性的货币政策将更多地带来物价水平上涨,而不是产出增加。在此基础上,本文还区分了劳动者的收入、工龄、户口、企业类型、行业等特征,对不同人群的工资粘性进行了细致测算。进一步,本文创新地区分并估算了名义工资的向上粘性与向下粘性,发现自2002年以来,中国劳动力市场的向下粘性不断增大,而向上粘性的变化趋势并不明显。     

Wage Flexibility and Unemployment: The Keynesian Perspective Revisited

Keynes' main concern in the General Theory is about the capacity of an economy to return to full employment equilibrium when subject to a (negative) demand shock. He maintains that money wages cuts may not help reabsorb unemployment, as they do not necessarily imply a fall in real wages. On the contrary, wage rigidity may be necessary for avoiding that a cumulative process propels the economy far away the full employment equilibrium. Co‐ordination failures in the investment‐saving market are behind this conclusion. However, the analysis is carried out within a static equilibrium framework. This paper is an attempt to focus on the problems of intertemporal co‐ordination arising within the context of a sequential economy. Our analysis of the out‐of‐equilibrium process of adjustment stirred by a shock allows to generalize the original Keynesian intuition. Unemployment emerges as the result of a lack of co‐ordination due to irreversibly constrained choices, and not only nominal but also real wage flexibility does not necessarily help to restore equilibrium. As a matter of fact, it may even be harmful, by triggering processes that make the economy diverge from equilibrium. Our analysis has important analytical implications as regards the role of market imperfections and the interpretation of the effects of monetary policy.     

技能型技术进步、南北贸易与工资不平衡

本文试图将技能型技术进步与产业内贸易置于一个框架中对工资不平衡现象进行理论解释。自由贸易通过促使发达国家产品质量阶梯提升型的技术进步而加剧了该国的工资不平衡程度;同时,自由贸易通过促使发展中国家产品种类数增加型的技术进步而加剧了该国的工资不平衡程度。南北贸易在拉大相对工资差距的同时促进了技能型技术进步。     

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。     

Product market deregulation and the US employment miracle

We consider the dynamic relationship between product market entry regulation and equilibrium unemployment. The main theoretical contribution is combining a job matching model with monopolistic competition in the goods market and individual bargaining. We calibrate the model to US data and perform a policy experiment to assess whether the decrease in trend unemployment during the 1980s and 1990s could be directly attributed to product market deregulation. Under our baseline calibration, our results suggest that a decrease of less than two-tenths of a percentage point of unemployment rates can be attributed to product market deregulation, a surprisingly small amount.     

技能溢价与工资不平等理论研究进展

尽管技能偏向性技术进步假说为理解技能溢价和工资不平等提供了一个较好的分析框架,但依然存在不一致的研究结果.争议主要集中在资本与技能之间的互补关系、劳动力市场制度变迁以及技术和贸易哪一个是造成收入差距拉大的主要原因等几个方面.未来的研究将会建立一个统一的理论框架,分析各因素在解释工资不均衡程度增加时的相互作用.     

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。     

垄断行业工资改革的可行性研究——基于国际垄断行业视角

在垄断行业中,员工的工资一般高于其他行业,表现出收入分配的不平等.引起垄断行业工资问题的原因很多,垄断行业工资问题也对社会经济各方面产生着重要影响,导致公共福利受损,减少了劳动者的流动及其对人力资本的投入,加剧了社会收入的不公平.对于垄断行业工资所引发的种种问题已经受到社会各界的重视,各国政府已开始采取措施解决这些问题,把竞争机制等改革引入垄断行业.
