中国工会存在工资溢价吗* ——基于控制样本选择性偏差的Blinder Oaxaca回归分解

本文采用2008年中国社会综合调查数据,运用工具变量的方法,研究了中国工会的工资溢价问题。研究结果表明,工会会员与非工会会员之间的小时工资差异主要是由禀赋效应造成的,系数效应和交叉效应并不明显。换句话说,工会工人的资源禀赋和工作特征禀赋等是造成工资差异的主要原因,工会对工资没有明显的直接影响。工会会员在入会倾向方面具有明显的群体特征。最后本文提出了加强工会有效性的两点建议。     

Unions and wage inequality: The roles of gender,skill and public sector employment

We examine the changing relationship between unionization and wage inequality in Canada and the United States. Our study is motivated by profound recent changes in the composition of the unionized workforce. Historically, union jobs were concentrated among low-skilled men in private sector industries. With the steady decline in private sector unionization and rising influence in the public sector, half of unionized workers are now in the public sector. Accompanying these changes was a remarkable rise in the share of women among unionized workers. Currently, approximately half of unionized employees in North America are women. While early studies of unions and inequality focused on males, recent studies find that unions reduce wage inequality among men but not among women. In both countries, we find striking differences between the private and public sectors in the effects of unionization on wage inequality. At present, unions reduce economy-wide wage inequality by less than 10%. However, union impacts on wage inequality are much larger in the public sector. Once we disaggregate by sector, the effects of unions on male and female wage inequality no longer differ. The key differences in union impacts are between the public and private sectors—not between males and females.     

Balance of payments,the Harrod foreign trade multiplier and economic growth: the European and North American experience, 1970–85

This paper examines the assoication between Canadian unions and their member' attitudes. Data on job satisfaction indicate that unionized workers in Canada are less happy with the quality of their jobs than non-union workers. The former, however, are more satisfied with their financial compensation and job security than non-members.     

Trade union membership and earnings in Kenyan manufacturing firms

This study analyses the effect of trade unions on male earnings in the Kenyan manufacturing sector using a regression method, which takes into account endogeneity of the union status of workers. In contrast to earlier studies of the Kenyan labour market that report a negative effect of unions on wages, a positive effect is found. The study further shows that elite workers tend to abstain from union membership.     

Turkish trade unionists and Turkey’s membership of the European Union

In all the discussions regarding Turkey’s accession to the EU, little attention has been paid to the views of workers. This paper provides a statistical analysis of the views of over 6000 Turkish trade union members on Turkey’s EU membership. Parameters are estimated using multilevel probit models where the nested structures of workers into trade unions and federations were taken into account since they shared some joint characteristics because of belonging to these organisations. It confirms the extensive disillusion with the EU found elsewhere in Turkish society but more interestingly it disconfirms an idea that those inside the EU may too easily assume to be the case: that it is those with what might be considered modernist characteristics among the Turkish population who are most likely to be in favour of EU entry. The idea seems to chime well with assumptions that the EU is a progressive, modern force. But whatever the validity of such a view, EU entry is not in fact found to be the favoured goal of the young and the best educated: it is older workers who are the most likely to support entry and those who are educated to the highest level the most likely to oppose it. Amongst the main three trade union federations there is also a greater propensity of members of trade unions affiliated to Hak Is (the Islamic federation) to support entry than those in Turk Is (centre right) or DISK (historically the most militant).     

EMPLOYEE PARTICIPATION: AN EVALUATION OF LABOR POLICY ALTERNATIVES

This paper reviews the theoretical and empirical literature on employee participation (EP) and the legal status of EP programs. The effect of EP on firm performance theoretically is indeterminate. However, properly implemented, EP can increase productivity and advance employee interests. Read literally, the National Labor Relations Act's (NLRA) prohibition of company-dominated unions prohibits EP in nonunion workplaces. This paper critiques four proposals to amend the NLRA based on the EP literature. EP is most likely to increase productivity if employees receive decision-making power. Two policies would accomplish this: (i) government mandated employee participation committees or (ii) increased legal protection of unions. The latter policy promotes power-sharing in a voluntary system. A third approach, abolishing the prohibition of company-dominated unions without otherwise changing labor laws, would encourage all forms of EP and union decline .     

The “greening” of trade unions and the demand for eco-taxes

By embedding labour market bargaining considerations in an influence-seeking framework, we show how a union's stance on environmental policy depends on the exposure of their members to the risk of job loss. With a risk of unemployment, unions lobby with employers to resist stricter environmental policies. When employment is secure, unions may support policies that reduce employment opportunities for nonunion workers. “Environmentalism” can therefore arise without explicit environmental concerns among workers. Consequently, pollution taxes may yield a negative welfare dividend in the form of inefficiently high unemployment.     

THE CONTEMPORARY DECLINE OF UNION STRENGTH

This paper reviews six explanations for the contemporary decline in United States union strength. The authors, after reviewing the conceptual basis and available evidence for each of these explanations, conclude that–for the present–each explanation has some merit. In other words, the contemporary decline in union strength results from the combined impact of various forces. However, employer suppression activities (e.g., illegal discharges for union activities) apparently represent the single most powerful explanation for union decline. Attempts by unions or policymakers to reverse this decline are more likely to be effective if the multiple causes of union decline are better understood.     

The impact of labour unions on external auditor selection and audit scope: evidence from the Korean market

We examine whether labour unions influence external auditor selection and audit scope. As a major user group of financial information, labour unions likely demand financial information of high quality and thus high-quality audits. As a union’s request for wage increases is likely strong when a firm is performing well, management facing wage negotiations with the labour union has incentives to manipulate earnings downward and may therefore prefer auditors who allow more discretion. Using union data unique to Korea during 2005–2008, we find that firms with a stronger labour union tend to choose higher-quality auditors (i.e. Big N or industry specialist auditors). We also find that unionization is negatively (positively) associated with positive (negative) abnormal audit fees and audit hours, and the effects are more pronounced when the union is stronger and more active. Given that departures from normal audit fees and audit hours in either direction arguably impair audit quality, this finding is consistent with our prediction of unions’ demand for high-quality audits. Overall, our findings suggest that labour unions play an important role in determining audit quality.     

Labour market segmentation and union wage gaps

Abstract

There has been a great deal of research regard the effects of unions on union – non-union wage gap. Most of the studies regarding the impact of unions on wages have assumed that apart from the division between union and non-union workers, the labour market is relatively homogeneous. A number of economists, however, have argued that the labour market is segmented, implying that there are distinct labour markets and that some workers employment opportunities are concentrated in “bad jobs” while other workers employment opportunities are concentrated in “good jobs” which are rationed.

This paper will explore whether the relative wage differential between union and non-union workers differs between the independent primary, subordinate primary and secondary labour markets. Labour market segments are defined using “job zones”. “Job zones” are distinct groups defined by the level of specific vocational preparation necessary for a particular occupation, allowing for the comparison of skill levels and training for each occupation. The data on “job zones” comes from the Occupational Information Network database (O?Net). We estimate separate equations for union and non-union workers in each segment using data from the Current Population Survey and calculate union non-union differentials for each labour market segment. The findings of this paper suggest that the greatest differentials are in secondary labour markets followed by differentials in the subordinate primary labour market and that the smallest wage differentials are in the independent primary labour market.     

Trade and unions: Does size matter?

Our empirical analysis builds upon the hypothesis that unions are detrimental to a firm's efficiency. Using a rich survey of German manufacturers, we investigate firm-level determinants on the probability of collective wage bargaining with particular focus on the impact of a firm's engagement in foreign markets. An interesting and very robust finding is that exporters are less likely to engage in union wage bargaining. This finding is in line with a pessimistic perception of unions. The negative effect of collective bargaining can be offset by efficiency gains for larger exporters, who can benefit from operation cost saving effects. Size does matter as larger firms export and may find bargaining with a single entity representing the workforce more convenient than bargaining with each worker individually. We are using firm level information on IT investment as instrument for the export dummy and successfully test for the validity of this instrument.     

The effect of ethnic diversity on the participation in social groups: Evidence from trade unions

This paper advances the hypothesis that individuals in more ethnically fragmented societies, participate less in social groups. More precisely, the empirical analysis places the spotlight on trade unions and investigates whether ethnic diversity affects the decision of workers to participate in them. The analysis takes place along two layers: (a) country-level and (b) individual-level. First, building on a set of innovative instruments derived from the parasite-stress theory of values and sociality, our country-level analysis seeks to exploit exogenous sources of variation in ethnic diversity and establish a convincing causal relationship between ethnic diversity and trade union density across countries. In turn, we employ individual-level data from the European Social Survey (ESS) and investigate whether immigrants who cοme from more ethnically fragmented societies participate less in trade unions in their European countries of residence. Consistent with the prediction of the theory, both layers of the empirical analysis provide robust evidence of a negative, sizeable and highly significant effect of ethnic diversity on the participation in trade unions.     

The determinants of training participation in Singapore

This article uses the Singapore Labour Force survey data to examine the determinants of workers’ participation in training programmes in Singapore. The results show that different socio-demographic and employment related characteristics affect the training participation of workers. Well-educated and better paid workers are much more likely to participate in training programmes than others. Age has a positive impact on training participation for younger workers (under 37 years), but a negative effect on older workers’ participation. The results also indicate that occupational affiliations have a significant impact on training participation. We also find that married workers seem to be less likely to participate in training programmes, but the difference between married and single is only significant at the 10% level. Finally, gender does not have any significant effect at any conventional level although the coefficient on the female dummy is positive, suggesting females might be slightly more likely to participate in training programmes.     

Bargaining over effort

Employment contracts generally specify both the reward for labour and the conditions of employment. Although it is clear how unions affect the payment received by workers, the effect of unions upon working conditions, particularly the contracted effort level that must be supplied, is not so well-understood. This note analyses the generalised Nash bargain between a union and a firm over employment level and effort level. Under standard assumptions, it is shown that an increase in union power always leads to a reduction in the agreed effort level. The effect upon employment is dependent upon whether the firm has the ‘right-to-manage’.     

What does the experience of German monetary union tell us about the theory of monetary union?

This paper summarizes the modern theory of monetary unions to identify in what circumstances such unions are supposed to impose low costs on, and give substantial benefits to, their members and then considers the case of the effect on Eastern Germany of German monetary and economic union. This union satisfied most of the conditions for low cost and high benefit, yet the initial impact of union was a severe fall in economic activity in Eastern Germany. The paper concludes that the conventional theory is deficient in ignoring the effects on the poorer member countries of a union of the expectations engendered by the creation of the union, and argues that an explicit regional policy is required in a union of members of widely different income levels.     

Labour unions and leverage: evidence from firm-level union data

ABSTRACT

Using firm-level labour union data from Japan, this paper investigates the effect of labour unions on firm leverage. We find that as union coverage increases, both the level of and extent of change in leverage decreases. These relations remain robust when a firm falls into deficit. We also find that firms with higher union coverage have a higher interest coverage ratio. In addition, we find that firms with higher union coverage are less likely to choose issuing debt compared to issuing equity when they face financial distress. Our results imply that significant employee influence enhanced by labour unions increases fixed costs, crowds out the firm’s debt capacity and consequently reduces the firm’s leverage.     

Do credit unions have distinct objectives? Evidence from executive compensation structures

Credit unions compete directly with commercial banks in markets for consumer financial services yet receive an exemption from federal corporate income tax. Commercial banks claim that credit unions are no different than banks and that the credit union tax exemption represents an unfair competitive advantage. Credit unions counter that while they offer similar products and services, they differ from commercial banks in terms of structure and mission, given their not-for-profit, cooperative status. In this paper, we test for substantive differences in the objective functions of commercial banks and nonprofit credit unions by comparing CEO compensation structures. Drawing on the relevant principal–agent literature, we provide several arguments to support the hypotheses that credit union boards of directors establish lower-powered incentive contracts with their CEOs relative to similarly sized commercial banks, and offer lower total compensation. We find that credit union CEOs receive approximately 250% less performance-based compensation relative to CEOs of similarly sized community banks. Bank CEOs also earn approximately 15% to 20% more total compensation on average. The results are generally robust to controlling for CEO- and board-level characteristics, local economic conditions, and institution-level indicators of size, growth, complexity, liquidity and risk. The findings suggest important differences in incentive structures and objectives between banks and credit unions.     

Trade union power and jobs: theory and policy

This paper looks at the relationship between trade union power and jobs in a capitalist economy. It is argued that trade unions, as they threaten profitability, may hinder the functioning of capitalist economies. But, any adverse effects of trade unions on jobs arise because of the constraints imposed on trade union activity by the state and capitalists. In alternative forms of economic organization, trade unions are not likely to reduce the number of jobs. The implications of this argument for policy towards trade unions are also discussed.     

工会主席身份是否影响员工留职意愿—基于2016年广东南海"雇主-雇员"匹配数据的实证研究

文章利用2016年广东南海"雇主-雇员"匹配数据,着重考察工会主席身份对员工留职意愿影响的作用机制与效应.研究结果表明:工会主席身份对员工留职意愿有显著影响.工会主席越是来自基层管理者的企业,其员工留职意愿越强,且该结论不受员工特征、工会主席特征和企业(主)特征的影响.来自基层的工会主席主要通过谈判、协商等方式,促使企业增加薪资、改善福利、按标准发放加班工资,促使企业签订劳动合同、延长劳动合同期限以及提升员工安全感,以此来影响员工的留职意愿.这一研究发现可为新时期企业如何有效留住员工提供新的思路和政策洞见.     

THE DECREASING INFLUENCE OF DOMESTIC MARKET STRUCTURE ON RACIAL EARNINGS DIFFERENTIALS: 1984 TO 1996

This study investigates the market concentration/racial earnings discrimination relationship in two periods: 1984–90 and 1991–96. In each period, the racial wage gap and the residual wage gap are compared for union and nonunion workers in monopolistic and competitive industries. The authors find no evidence of market structure–driven discrimination for union workers in either period. However, from the first to the second period they find evidence of increased racial earnings differentials for nonunion workers, yet market structure–driven discrimination decreases. The authors suggest that concentration has become a less effective measure of market power and firms' latitude to discriminate. (JEL J31, J71 )
