Regression Results of the Union Impact on Pay Levels in New Zealand Public Service

<p>International studies almost uniformly conclude that union members receive higher wages than their non-union counterparts. This study investigates differences between collective and individual salaries using the New Zealand State Services Commission's Human Resources Capability Survey 2005. It explores the impact of collective bargaining on pay by controlling for a large number of employee and employer characteristics. As very little research has been carried out on the subject in New Zealand, I focused on the international literature in order to identify the major factors that explain the magnitude of union/non-union wage differential. Major industrial changes, which have shaped the NZ public service bargaining structure and its outcomes are identified. A range of statistical tests are used to examine the pay differences between collective and individual agreements in New Zealand public service. I, first, carry out basic comparisons of the average collective and individual wages across gender, employment type, occupations, ethnicity, age, employer size and tenure, followed by numerous multivariate regressions to work out the true contributing factors to the union/non-union wage differential. Finally, I analyze the results in the unique NZ context to allow new ideas and theory to emerge and compare it to international trends. Looking at the basic comparisons, I found that, in the New Zealand public service, employees on individual agreements earn significantly higher wages then those who are covered by collective agreements. However, multivariate analyses have revealed a different picture. The study found that occupational composition is the largest contributor to the variability in collective/individual pay in NZPS. With the exception of the senior, high skilled and specialised employees, no pay differential was found between collective or individual agreements in the New Zealand public service.</p>

Social Class, Union Strategies, and Preference in Wage Outcomes in Norway

This article explores a potential socialization effect of unions on member preferences in wage outcomes and bargaining structures. This challenges notions of union wage policies simply reflecting the material self-interest of their constituency. In their formative role, unions can either propagate more redistribution in society, that is, increasing equality, or increasing societal inequalities, arguing instead for equity. However, equity could be measured either individually or collectively, where the latter would mean increasing societal wage inequalities while favouring intra-union equality. By putting perspectives on worker preferences and political economic theories in dialogue with the literature on the role of unions in constructing notions of equality/equity, we discuss on union strategy as it relates to their socialization effects and members’ attitudes towards income inequality and bargaining structures. Analysing survey data, we find that socioeconomic status has greater influence on preferred wage outcomes, while union membership has more influence over bargaining structure.

Corporate social responsibility in unionised network industries

In a duopoly network industry with decentralised union wage setting, this paper studies the impact of the firms’ engagement in consumer-friendly corporate social responsibility (CSR) on profitability and welfare. It is shown that, regardless of whether the wage setting occurs prior to or after the choice of the CSR levels, being a CSR-type firm rather than a simple profit-maximiser can lead to larger profits and thus higher welfare for their owners/stakeholders. However, the welfare analysis reveals that there is always conflict of interest between the firms’ owners on the one side and consumers, unions, and society on the other side, with respect for the timing of the decision about CSR relative to that of the wage setting.

Do local union strategies explain the (unexpected) union pay premium in China?

PurposeThe authors investigate the extent to which differences in provincial union legislation have impacts on the union earnings premium.Design/methodology/approachContent analysis of provincial union regulations of 25 provinces is conducted to create two indices: one reflecting the degree of stringency of the local requirement that unions be established in a timely fashion and the other reflecting requirements for employers to negotiate wages with the union. The authors use individual level data from the China Family Panel Studies (CFPS) of 2010 to estimate the union earnings premium.FindingsThe authors find that unionised workers in China receive an earnings premium ranging from 6.4 to 9.6%, which is in range of other studies (but not all) for China that tend to find a (perhaps surprising) union wage premium in spite of the fact that unions tend to be “company unions” designed to foster stability and growth and to serve as a transmission belt for the wishes of the Party rather than bargaining for the benefit of their members. The authors also find that provincial requirements to establish unions in a timely fashion enhance the impact of unions on the earnings of their members, but provincial requirements to negotiate wages dampen the effect of unions on the earnings of their members. Reasons for these results are discussed.Originality/valueDespite this lack of independence of the Chinese unions, research continuously finds that Chinese unions have effects that are surprisingly similar to those of unions in Western countries. This paper drills deeper into the underlying mechanisms to see if local union strategies, exemplified by provincial union legislation, can explain the unexpected union effects on compensation. To the authors’ knowledge, this is the first paper to do so. Moreover, the authors use individual-level data in contrast to most studies on China that use firm or provincial level aggregate data.

Revisiting Union Wage and Job Loss Effects Using the Displaced Worker Surveys

Estimates of union wage effects have been challenged by concerns regarding unobserved worker heterogeneity and endogenous job changes. Many economists believe that union wage premiums lead to business failures and other forms of worker displacement. In this article, the authors examine displacement rates and union wage gaps using the 1994–2018 biennial Displaced Worker Survey (DWS) supplements to the monthly Current Population Surveys. For more than two decades, displacement rates among union and non-union workers have been remarkably similar. The authors observe changes in earnings resulting from transitions between union and non-union jobs following exogenous job changes. Consistent with prior evidence from the 1994 and 1996 DWS, findings show longitudinal estimates of average union wage effects close to 15%, which are similar to standard cross-section estimates and suggestive of minimal ability bias. Wage losses moving from union to non-union jobs exceed gains from non-union to union transitions.
