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.     

Redistribution Through Education and Other Mechanisms Under Capital‐Market Imperfections and Uncertainty: A Welfare Effect Analysis

Abstract. This paper considers a two‐period model of endogenous human capital formation under the credits‐market imperfection and uncertainty assumptions. We compare in the first part of the paper ex‐ante and ex‐post general‐equilibrium effects of the education subsidy policy to those of the negative income tax and the unskilled wage subsidy regimes. We show that the education subsidy policy raises an efficiency‐inequality trade‐off issue, and therefore it is optimal unless the degree of inequality aversion is relatively high and financing the subsidy is not too distorsive. Public loans are generally claimed to provide a solution for such issue. We explore the implications of implementing the public loan under several schemes in the second part of the paper. We show that combining between a pure public loan and education subsidies provides higher levels of welfare than these two policies taken separately provided that the inequality aversion degree is high. For low degrees of inequality aversion, the pure public loan is the optimal policy.     

Union Power and (Un)Employment

Is the monopoly face of unions, i.e. their ability to enforce wages above what non-unionised firms would pay, harmful to employment and output? It is shown that a positive answer to this question is far less compelling than commonly held views based on a negatively sloped labour demand curve suggest. First, the labour demand curve may be irrelevant for the employment decision of unionised firms. Second, even if the labour demand curve is relevant, selfish union workers are likely to accept a system of wage discrimination which does away with discrepancies between the marginal product and the reservation wage. And third, the labour demand curve may have a positive slope.     

Efficiency‐wage Unemployment and Economic Welfare in a Model of Endogenous Growth

This paper examines positive and normative implications of efficiency‐wage‐induced unemployment within a model of endogenous growth. Sector‐specific impacts of the wage rate on labour efficiency establish a correlation between the growth rate and the rate of unemployment. The sign of this correlation is determined by the intersectoral wage differential. Despite the existence of unemployment, decisive positive properties of the full‐employment model are preserved. However, welfare implications of the full‐employment model may be reversed. The optimal policy can be to reduce growth, while at the same time raising unemployment.     

Union–Firm Bargaining,Productivity Improvement and Endogenous Growth

This paper presents a growth model with two sectors. In the high‐tech sector, R&D increases productivity and union–firm bargaining determines wages, but in the traditional sector there are neither R&D nor labour unions. The government is able to regulate union bargaining power. The main results are as follows. Because firms try to escape wage increases through the improvement of productivity by R&D, the increase in union bargaining power boosts R&D and growth. It is welfare enhancing to strengthen (weaken) unions when the growth rate is below (above) some critical level. A specific rule is presented for when de‐unionization is socially desirable.     

Firm‐level Evidence on Gender Wage Discrimination in the Belgian Private Economy

In this paper we explore a matched employer–employee data set to investigate the presence of gender wage discrimination in the Belgian private economy labour market. Contrary to many existing papers, we analyse gender wage discrimination using an independent productivity measure. Using firm‐level data, we are able to compare direct estimates of a gender productivity differential with those of a gender wage differential. We take advantage of the panel structure to identify gender‐related differences from within‐firm variation. Moreover, inspired by recent developments in the production function estimation literature, we address the problem of endogeneity of the gender mix using a structural production function estimator alongside instrumental variable‐general method of moments (IV‐GMM) methods where lagged value of labour inputs are used as instruments. Our results suggest that there is no gender wage discrimination inside private firms located in Belgium, on the contrary.     

Permanent Disadvantage or Gradual Integration: Explaining the Immigrant–Native Earnings Gap in Sweden

Theoretical explanations suggest that wage differentials between immigrant and native workers are generated either by differences in the acquisition of human capital or by various forms of exclusion of immigrants from fair labour market rewards. We evaluate the labour quality and labour market discrimination hypotheses by using a large sample of Swedish employees in 1995. Our findings show that labour market integration is relatively unproblematic for immigrants from Western countries, whereas immigrants from other countries, especially from Africa, Asia and Latin America, face substantial obstacles to earnings progress when entering the Swedish labour market. For the latter group of countries, extensive controls for general and country‐specific human capital reduce the earnings differentials. However, the remaining gap is of a non‐trivial magnitude. Thus, the labour quality hypothesis accounts for a part of the observed native–immigrant wage gap, but the remaining differentials can be interpreted in terms of labour market discrimination.     

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.     

Unionization and Labour‐market Discrimination: A Closer Look at Non‐unionized Workers

This paper introduces a model that examines the effects of unions on pay and hiring gaps between non‐unionized men and women in the context of imperfect competition. Although the model does not question the advantages unions obtain for their members, it does show that (1) unions increase wage and occupational discrimination for non‐unionized workers; (2) the non‐unionized sector does not constitute a good comparison group for use in analysing the impact of unions on gender discrimination; and (3) public policies targeting gender differences in occupational sorting can also have a positive impact on gender wage differentials.     

Explaining Labour Turnover: Empirical Evidence from UK Establishments

Abstract. This paper investigates the determinants of labour turnover using establishment‐level survey data for the UK. The main contribution of our paper is that it estimates the impact of wages, unionization, training and other aspects of working conditions on labour turnover. Our main findings are: (i) turnover is inversely related to the relative wage; (ii) unionism reduces turnover: this is due mainly to the ability of unions to improve conditions of work rather than the voice‐exit model of Freeman; (iii) there is a complex relationship between turnover and training; and (iv) turnover is lower in the ‘high‐tech’ sector.     

The Role of Profit Sharing in Dual Labour Markets with Flexible Outsourcing

We combine profit sharing for high‐skilled workers and outsourcing of low‐skilled tasks in a partly imperfect dual domestic labour market, which means that only low‐skilled labour is represented by a labour union. In that framework we analyse how the implementation of profit sharing for high‐skilled workers influences the amount of outsourcing and the labour market outcome for low‐skilled worker. By doing this, we use some specific assumptions, e.g. exponentially increasing outsourcing costs or the wage for low‐skilled workers will be determined by a union whereas the wage for high‐skilled workers is given. Assuming that low‐skilled labour and outsourcing are interchangeable we show that profit sharing has a positive effect on the wage for low‐skilled workers and helps to decrease wage dispersion. However, under these circumstances, profit sharing enhances outsourcing. Concerning the employment effects for high‐ and low‐skilled workers, we show that there is an employment reducing effect due to higher wages for low‐skilled work, which can be offset by higher productivity of highly skilled workers, as the domestic labour inputs complement each other.     

The Early‐career Gender Wage Gap among University Graduates in the Finnish Private Sector

In the Finnish private sector, the gender wage gap increases significantly during the first 10 years after labour market entry, accounting for most of the lifetime increase in the gender wage differentials. This paper investigates the reasons for this gender difference in early‐career wage development. By focusing on university graduates the paper considers several explanations based on the human capital theory, job mobility, and labour market segregation. The results suggest that only about 20–26 per cent of the average early‐career gender wage gap is explained by gender differences in experience, the field of education, employer characteristics, and mobility. A substantial unexplained gap thus remains. Of the investigated factors gender differences in the field of education and work experience matter most.     

Union Power in a Welfare State

Abstract. Most West European countries have suffered from stagflation for many years. Mainstream economics has debated the question in particular in terms of the demand and supply of goods, labour and capital. But in recent contributions a new element has been introduced: the institutional structure of the economy as a source of imbalances. In this article we focus on the institutions of the labour market. For more than a century West European unions have been struggling to transform market economies into a more efficient and just order. Moral persuasion, strikes, and revolutionary threats were their main weapons. After the Second World War governments yielded to the pressure by building up, together with the unions, a welfare state. During the sixties however, the struggle was renewed, although the governments continued to improve the social security system and maintained their responsibility for full employment. A short sketch will be given of the ideological struggle during the first half of the twentieth century, leading to a significant institutional change: the transformation of a system of private wage bargaining into a collective wage bargaining system. Then the neoclassical, the Marxist and the Keynesian view on the effects of union power on the economic performance of a market economy and of a welfare state will be presented. The conclusion is drawn that the methods required to transform a market economy into a welfare state are anomalies as soon as a welfare state is more or less realized. This is particularly so, because the transformation of a welfare state into a centrally planned economy cannot be considered desirable. In present circumstances, it would be appropriate to pay more attention to the design of an extensive system of mediation and arbitrage to reduce the use of the strike weapon.     

Technology Import and Industrial Employment: Evidence from Developing Countries

Abstract. This paper based on panel data across countries examines the possible effect of the imported technology on labour absorption in the industrial sector, after controlling for real wage rate and GDP per capita. Findings tend to suggest a negative relationship between the two. Technical efficiency index derived on the basis of the stochastic frontier function framework is also negatively affected by the import of technology. Without enhancing the knowledge relating to the mechanisms of exploiting the new technology acquired from abroad, a mere increase in import of technology would mean rising unutilized capacity. And this could be due to the poor skill base of the available human capital. Investment in human capital in terms of skill formation, up‐gradation, and training on the one hand and technological advancement to suit the internal labour market conditions are the two important policy conclusions for reviving the role of industry as the engine of pro‐poor growth.     

The benefit of market-based governance devices: Reflections on the issue of growing economic inequality as a corporate concern

Growing economic inequality in advanced economies is explained by a variety of conditions and mechanisms, but a growing literature emphasises how corporate governance decisions serve to transfer wealth from labour to capital owners, including shareholders. The article introduces the term governance devices to examine how a consistent annual real wage growth (calculated to 1.20 percent) over the period 1997–2017 has been negotiated in Sweden, based on a bilateral market-based industrial agreement between the employer organisation and a confederation of trade unions. The article stresses the importance of governance decisions in counteracting secular stagnation of real wage growth, which reduces the purchasing power in an economy and incurs other externalities. Corporate governance is, therefore, a key mechanism in resolving the issue of how to allocate the residual cash being generated in the corporate production activities so that it benefits all constituencies and balances short-term returns to shareholders and medium-to long-term economic growth and stability.     

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.     

Endogenous Contracts in Unionized Oligopoly

We study the endogenous determination of contracts in a unionized oligopoly and the welfare implications thereof. Alternative contracts specify the sequencing in the selection of R&D and wages. They can be classified as ‘fixed’ when the unions set wages before the firms make their R&D decisions or ‘floating’ when the sequencing of these choices is reversed. If the unions are highly employment‐oriented, we find that either all firm–union pairs choose floating‐wage contracts or both contract types may coexist depending on the degree of technological spillovers. However, when the unions have stronger preference over attaining a good wage deal, then it becomes very likely that fixed‐wage contracts will endogenously emerge because they can serve as an insurance device against oppor tunistic wage increases. Our welfare analysis suggests that welfare‐improving contracts may nevertheless not always arise in equilibrium.     

Preliminary Evidence on Wage Setting in Greek Manufacturing

Abstract. The negotiating power of the unions and their role in wage determination depends on the level of centralization of the wage bargaining system as well as on other institutional arrangements. In this study, we estimate a set of wage equations in order to study the employment effects of different unions’ stances in wage determination as well as to investigate other characteristics of employment in Greek manufacturing. We discriminate between workers and employees (blue‐ and white‐collar workers) and between sectors in order to capture differences in the relative supply as well as differences in the negotiating power among the staff of the same industry. Empirical findings reveal that the persistence of unemployment arises as a result of the great bargaining power of the unions in negotiations at a sectoral level. White‐collar workers exhibit a stronger negotiating power compared with blue‐collar workers because of differences in the institutional framework.     

Modelling Labour Demand Dynamics beyond the Frictionless Environment

Abstract. In this study we develop a simple econometric model for labour demand dynamics by explicitly considering deviations from the standard frictionless economic environment. In particular, we explore the potential effect on labour demand of capital market imperfections, labour market institutional rigidities in the form of union power, and the impact of uncertainty. In addition, in the presence of uncertainty, adjustment costs and irreversibility emerge as an important factor that introduces an option value of waiting. According to our results, leverage exerts a direct negative impact on employment dynamics indicating that capital market imperfections are indeed present. Moreover, leverage is found to also affect the adjustment process of employment. Finally, we document asymmetric effects of frictions on labour demand across different size groups that imply a higher vulnerability of small and medium sectors with respect to debt levels. Uncertainty exerts a significantly negative impact on labour demand, which is compatible with presence of partial irreversibility of employment decisions. Finally, unions over and above their effect via higher wages are positively related to employment, a finding that is indicative of their pursue for job security.     

Urban Versus Rural Return to Human Capital in Portugal: A Cookbook Recipe for Applying Assignment Models

Abstract. The Portuguese economy has been characterized by modernization since the post‐war period, and Lisbon is a centre of this process. This paper analyses rates of return on human capital in Lisbon versus the rest of the country in the period 1982–92. An assignment model of heterogeneous workers to heterogeneous jobs is applied. We introduce the concept of the complexity dispersion parameter, which measures job heterogeneity and the ease of substitution between worker types. It is free dimension and can be compared across countries. We also develop a cookbook recipe for the estimation of this parameter. The main implication of the model — a high return to human capital is associated with similar workers being assigned to more complex jobs — is confirmed by the data. The complexity dispersion parameter suggests that paying half of the optimal wage level at least doubles the cost per efficiency unit of labour.
