Union Wage Setting,Employment and Investment: a Survey of Theory and Empirical Evidence

Abstract. This paper provides a survey of recent theoretical and empirical research on union wage setting, employment and investment. The basic models of union wage setting and employment are presented in a unified framework. The distinction between insiders and outsiders is introduced as an extension of the basic models. Empirical evidence on union preferences and on the performance of the various models is accessibly ordered. Finally, attention is paid to the effects of strategic behaviour between union and firm on wages, employment and investment.     

Children and Gender — Wage Differentials

ABSTRACT: In this paper we present a test of wage discrimination between women and men in Italy, controlling for individual productive characteristics. We emphasise the importance, in empirical tests of wage discrimination, of explicitly modelling the reproductive role of women within the family. We show that ignoring the impact on women wages of the presence of children can seriously bias the results in favour of the hypothesis of wage discrimination. Our results illustrate that a considerable wages gap exists, but that only part of the observed differential can be attributed to pure discrimination; the remainder is explained either by heterogeneous productivity of men and women or by the effect of having children on female human capital formation.     

Wage Differentials between Ethnic Groups in Switzerland

This paper analyses the average wage differentials between various groups of immigrants and the Swiss workers. Classical Oaxaca‐Blinder decompositions are applied to a sample of 7,494 males (whose 1,070 immigrants) interviewed for the 1995 Swiss Labour Force Survey. Education and experience before and after migration are separately considered in two different ways. We control for sample selection in the wage and salary sector. We also investigate earnings differentials between natives and immigrants who arrived in the country before the age of 6. Our main results are that the part of differentials due to difference in coefficient varies strongly with different ethnic groups considered, that education is a strong determinant of the difference in observed characteristics and that second generation immigrants are fairly well assimilated in the Swiss labour market.     

Trade Unions,Wage Bargaining Coordination,and Foreign Direct Investment

Conventional wisdom is that a high trade union bargaining strength and a system of coordinated wage bargaining reduce the attractiveness of an economy as a location for foreign direct investment, although there is limited evidence for this. The paper takes panel data for 19 OECD economies to examine the relationship between trade union bargaining strength, bargaining coordi nation, and a range of incentives for inward foreign direct investment. It finds a strong negative effect of trade union density on inward foreign direct investment, which is dependent on the degree of wage bargaining coordination. A high degree of coordination weakens the deterrent effect of high union density, which is consistent with the notion that under certain circumstances a coordinated increase in wages can increase profits of the multinationals by hurting domestic firms.     

Temporary Contracts,Employment Protection,and Collective Bargaining

This paper examines the effect of employment protection in a matching model with endogenous job destruction, collective bargaining, and two types of employment contracts. Using this framework, we show that (i) the impact on job creation and job destruction caused by reducing the firing costs associated with temporary jobs depends on the labour unions' bargaining strength and the gap in firing costs between contracts; (ii) reducing the firing costs associated with permanent jobs unambiguously decreases equilibrium unemployment if labour unions have strong bargaining power; and (iii) the impact caused by the firing costs differs between collective and individual bargaining.     

Subsidies on Labour and Capital under Wage Bargaining

ABSTRACT: Micro-policy instruments are often grouped into labour subsidies and capital subsidies. The purpose of this paper is to investigate the effect on employment of labour and capital subsidies when the wage rate is endogeneous. The problem is studied within a sequential three-stage model, integrating the investment decision, wage-bargaining and the employment decision. The paper demonstrates that labour subsidies may fail, depending on technology and the risk aversion of the workers.     

Wage Bargaining and Profitability: A Disaggregative Analysis

Abstract. Previous analyses of the wage/profit relationship at a disaggregative level in Britain have given positive results for pre-war years but negative results for early post-war years. However, this is probably due to the increasingly unreliable nature of the enterprise- based profits series published in the National Accounts until 1982. We have constructed, instead, what are essentially establishment-based Census data on profits for fourteen manufacturing industries, up to 1986. We have also been able to extend the disaggregative unemployment data, the publication of which also ceased in 1982. The wage equations that we have estimated include profits and unemployment (and other variables) in an explicit Nash bargaining model, in line with widely held views as to the way that wage negotiations are actually conducted. The results obtained show a highly significant role for profits, as well as having other implications, notably the positive (hysteresis) effect of industry unemployment, by contrast with the normal negative effect of aggregate unemployment, and the important effects of relative wages - which play a large role in various disaggregative studies of the propagation of inflation.     

Trade Union Priorities and Wage Rigidity

ABSTRACT: The starting point of the paper is that trade unions engage in substitution once certain targets have been met. This implies that a priority-based or hierarchical model might be a better approximation to union behaviour. This model requires a two-part union utility function which changes when a satisfactory (or target) level of the priority variable (e.g. the wage rate) is met. After demonstrating the workings of such a model in a monopoly union framework, it is shown that there is real wage rigidity when the wage is below the target level. Employment increases only when the target wage has been achieved.     

Wage Drift: Phillips Curve vs Bargaining Models

ABSTRACT: The purpose of this paper is to shed light on the debate on market- versus bargaining-determined total earnings by examining whether models of wage drift based on wage-bargaining considerations empirically outperform models based on simple ad hoc formulations relating wage drift to excess demand for labour. The task is carried out by investigating the empirical performance of two bargaining models and two Phillips curve models in the context of data on the Finnish metal industry. The results suggest that the former perform better than the latter, thus providing support for the hypothesis that total earnings are bargaining-determined. Furthermore, the results are in line with the view that the superiority of wage-bargaining models is not only theoretical but also empirical.     

Employer Wage Differentials in Germany: A Comparative Note

The paper contributes to the growing empirical literature on employer wage differentials, presenting first estimates for West Germany and comparing them with recent findings from other studies for the USA, France and Denmark. The empirical results show that the variation of global employer wage differentials is comparatively low in West Germany and has remained stable during the first half of the 1990s. This low dispersion results from wage setting for blue‐collar workers, while cross‐country differences are negligible for white‐collar workers. Employer wage differentials have, however, become more important for the remuneration of West German blue‐collar workers during the period investigated.     

Welfare Effects of Local versus Central Wage Bargaining

The paper analyses the welfare effects of union bargaining (de)centralization in a dual labour market with a unionized and a competitive sector. We show that social welfare depends on both the structure of the union's objective function and the elasticities of labour demand in both sectors. The welfare‐maximizing employment allocation can be obtained under a high degree of centralization if the union maximizes the total wage‐bill. Otherwise, if the union is rent maximizing, welfare is higher under local bargaining. However, in that case neither central nor local wage setting yields the social optimum.     

Union Membership and the Union Wage Gap in the UK

We consider the choice of union membership in the UK and its effect on the union/non‐union wage differential allowing for the endogeneity of the union choice. We include identifying variables not previously used and find that correcting for selectivity is important and has a large impact on the estimated differential. Moreover, union choice is itself affected by the wage gap.     

Wage Structure,Incomes Policy and Decentralised Bargaining: the Case of Greece

Abstract. Developments in Greek industrial relations suggest that decentralised bargaining is not a panacea. The manufacturing wage structure in Greece has an exceptional course associated with the rise of informal decentralised bargaining. Interindustry wage differentials increased in a period of incomes policies aiming to narrow the wage structure. The influence exerted by inflation and unemployment is, compared to past evidence from the US. and the U.K., quite unconventional. Under informal bargaining, high-wage powerful industrial branches “benefit” from higher inflation and lower unemployment.     

Efficiency Wage,Fixed Employment Costs,and Dual Labour Markets

The standard efficiency wage‐based explanation of labour market dualism hinges on the existence of differences in monitoring across sectors. The paper proposes fixed employment costs as an alternative source of wage differentials for homogeneous workers. It shows that firms with larger fixed costs pay higher wages in order to elicit more effort from their workers, and tend to have higher capital/labour ratio and labour productivity. The model generates both involuntary unemployment and involuntary confinement in the secondary sector: high effort–high wage jobs are preferred to low effort–low wage jobs and either are preferred to unemployment. The proposed framework can also account for the various types of treatment of marginal jobs in primary sector firms envisaged by Doeringer and Piore (Internal Labour Markets and Manpower Analysis, 1971). In particular, an increase in fixed costs beyond a certain level may induce primary sector firms to restructure, segment production, and enter the secondary sector, thus converting their jobs into secondary jobs. From a welfare point of view, we cannot state in general the desirability of subsidizing fixed employment costs; however, we show that an employment subsidy financed by a wage tax is able to increase employment with no loss in terms of production.     

Unemployment Insurance Policy and Union Wage Formation

Abstract. The paper considers the wage and employment effects of alternative social security policies. Such a policy can take the form of a fixed benefit level or linking the level of unemployment benefits to private sector wages. The latter is an important social security policy instrument to guarantee an equitable distribution of income. A fixed benefit level policy yields lower wages and larger employment than an automatic link between the level of benefits and the wage rate. Further, if the government decides to make the link conditional on the stabilization of the tax rate, wages are lower and employment is higher than in both former alternatives. By endogenizing its social security policy, the government is able to reduce the loss in employment that the link policy brings about.     

Public-Private Wage Differentials in French-Speaking Africa: A Comparative Analysis

Abstract. In the framework of structural adjustment programs implemented in Africa, the idea that wages in the public sector are too high compared to those of the private sector is partly based on wage policies with regard to the public sector. But the existence of public-wage differentials, inducing a labour market segmentation within the modern sector, has rarely been the object of attentive examination. With the help of earnings functions, based on homogeneous cross-section and logitudinal data of seven capitals of French-speaking Africa, the author plans to verify this hypothesis. The main conclusion of this research is that distortions on the modern labour market of many African countries are less important than one may think. In most of the countries considered, public-private wage gaps are essentially attributable to characteristics of individuals. This suggests that policies aiming to reduce wages of the public sector are no longer justifiable, economically and socially.     

Male–Female Labour Market Participation and Wage Differentials in Greece

This paper is an empirical study of the development of labour market participation and wage differentials between males and females in Greece between 1988 and 1994. There is little known about the position of women in the Greek labour market. This paper uses survey data generated by the Greek National Statistical Service. The decision to engage in paid employment and the resulting remuneration are studied using selectivity–corrected earnings estimations. Oaxaca and Ransom decompositions and counterfactual analysis show that the adverse treatment of female labour market participation is the largest identifiable reason why the wage gap is there and why it increased between 1988 and 1994.     

Comparisons in Gender Wage Differentials and Discrimination between Germany and the United Kingdom

Due to the lack of consistent data, direct and robust comparisons of cross‐country labour markets have been virtually impossible. This study uses a new panel data series that controls for inconsistencies, thus overcoming this problem. This study estimates gender wage differentials and gender discrimination in the German and UK labour markets. Panel estimates are used to identify general wage differences between the two countries, with cross‐sectional comparisons undertaken to identify changes that have occurred between 1991 and 1993, that are consistent with known labour market policies. It is found that gender wage differentials are greater in the UK than Germany with employer discrimination against females attributed with the majority of the difference in both countries.     

Bargaining Power and Wage Determination: The Role of Outside Options

ABSTRACT: The paper analyses the wage bargaining process between an entrepreneur and his workforce when delays in agreement intrinsically reduce the amount of returns to be shared It is shown that the outside options of the workforce and the entrepreneur can be a systematic determinant of their bargaining power in contrast to what the Rubinstein (1982) model predicts The basic model is extended to analyse: (i) bargaining under multiple unionism; (ii) the- possible relationship between bargaining and efficiency wages; and (iii) under investment in workforce training.     

Wage and Productivity Differentials in Japan: The Role of Labor Market Mechanisms

This paper aims at explaining two stylized facts of the Lost Decade in Japan: rising wage inequalities and increasing firm‐level productivity differentials. We build a model where firms can choose between efficiency wages with endogenous effort and competitive wages, and show that it can replicate those facts. Using Japanese microeconomic data, we find support for the existence of efficiency wages in one group of firms and competitive wages in the other group. Based on those results, a simulation shows that the share of firms using efficiency wages has declined, within sectors, during the Lost Decade, as predicted by the model.
