Monopsonistic discrimination, worker turnover, and the gender wage gap

Motivated by models of worker flows, we argue in this paper that monopsonistic discrimination may be a substantial factor behind the overall gender wage gap. Using matched employer–employee data from Norway, we estimate establishment-specific wage premiums separately for men and women, conditioning on fixed individual effects. Regressions of worker turnover on the wage premium identify less wage elastic labour supply facing each establishment of women than that of men. Workforce gender composition is strongly related to employers' wage policies. The results suggest that 70–90% of the gender wage gap for low-educated workers may be attributed to differences in labour market frictions between men and women, while the similar figures for high-educated workers ranges from 20 to 70%.     

Job mobility and the gender wage gap in Italy

This paper investigates the contribution of gender differences in job mobility to the emergence of a gender wage gap in the Italian labour market. We show that over the first 10 years of labour market experience job mobility accounts for up to 30% of total log wage growth for men and only 8.3% for women, and that this difference is mainly due to differences in returns to mobility. The gender mobility gap is robust to the inclusion of individual, job and firm characteristics, to different ways of accounting for individual unobserved heterogeneity, and is mainly found for voluntary job moves. Looking at the characteristics of the jobs and the firms' workers move to, we find that moves to larger firms represent by far the main source of gender differences in returns to mobility. We offer two possible explanations for this finding; one which involves differences in bargaining behaviour and one which relates to the theory of compensating differentials.     

Gender differences in early-career wage growth

In Finnish manufacturing, the gender wage gap more than doubles during the first ten years in the labour market. This paper studies the factors contributing to the gender gap in early-career wage growth. The analysis shows that the size of the gender gap in average wage growth varies with mobility status, the gap being higher with employer changes compared to wage growth within firms. Several explanations for the gender gap in wage growth based on human capital theory and theory of compensating wage differentials are considered. However, much of the gap in wage growth remains unexplained. The distributional analysis of the wage growth shows that the female wage penalty increases significantly as we move along the conditional wage growth distribution, the increase being stronger with employer changes compared to within-firm wage growth.     

The Gender Wage Gap in Europe: Job Preferences,Gender Convergence and Distributional Effects

The gender wage gap has declined over time. However, most of the remaining gap is unexplained, partly because of gender convergence in wage‐determining characteristics. In this paper, we show the degree of convergence differs substantially across Europe. In some countries, predominantly in Eastern Europe, the gender wage gap is entirely unexplained. However, in other countries, differences between the characteristics of men and women explain a relatively large proportion of the wage gap. Gender differences in job preferences contribute 10% to the wage gap, which is more than job tenure, previous employment status or field of study. The role of job preferences is particularly strong at the top of the wage distribution.     

Men's wage inequality in Serbia's transition

Wage inequality is considered to have been quite compressed in socialist economies. In this paper I analyse how men's wage inequality has changed during the period of transition to a market economy in Serbia, a country which has experienced a particularly dramatic transition. Changes in the distribution of earnings are examined using the Lemieux (2002) decomposition methodology and five annual Labour Force Surveys (2001–2005). I find that the change in wage inequality is mostly driven by changes in wage premiums, while the effect of changes in the composition of the labour force is very small. Isolating the effect of the emerging private sector reveals that changes in the private sector size and wage premium account for an average 25 per cent of the changes in inequality during this period. Moreover, the minimum wage is found to exert a dampening effect on wage inequality.     

Setting the minimum wage

The process leading to the setting of the minimum wage so far has been overlooked by economists. There are two common ways of setting national minimum wages: they are either government legislated or the byproduct of collective bargaining agreements, which are extended erga omnes to all workers. We develop a simple model relating the level of the minimum wage to the setting regime. Next, we exploit a new data set on minimum wages in 68 countries having a statutory national minimum level of pay in the period 1981–2005. We find that a Government legislated minimum wage is lower than a wage floor set within collective agreements. This effect survives to several robustness checks and can be interpreted as a causal effect of the setting regime on the level of the minimum wage.     

The de-collectivisation of pay setting in Britain 1990–98: incidence,determinants and impact

What were the causes and consequences of declining collective bargaining coverage in Britain? The demise of collective bargaining did not lead to a greater use of individualised payment mechanisms, ‘high-involvement’ practices or productivity gains. Wage inequality rose as a result of the decline. However, workplaces that abandoned bargaining created more jobs. Overall, these results raise questions about Britain’s labour market performance during the 1990s because they suggest that falling unemployment as a result of weaker trade unions came at the price of slower productivity growth and widening male wage inequality.     

Wage incentives and wage rigidity: A representative view from within

A recent literature has used surveys of those who set wages to learn about the nature of wage incentives and the sources of wage rigidity. Methodologically, we overcome many of the objections that have been raised against this work. Substantively, we find that: (i) the reasons for real wage rigidity differ significantly between large and small firms, and between the high- and low-end of the labor market; (ii) efficiency wage mechanisms reinforce rigidities due to worker bargaining power; (iii) money illusion is a widespread phenomenon across all segments of the labor market; (iv) unions reinforce nominal wage rigidities due to external pay comparisons; (v) there appears to be gender differences in pay bargaining and work morale.     

Gender wage gap: A semi-parametric approach with sample selection correction

Sizeable gender differences in employment rates are observed in many countries. Sample selection into the workforce might therefore be a relevant issue when estimating gender wage gaps. We propose a semi-parametric estimator of densities in the presence of covariates which incorporates sample selection. We describe a simulation algorithm to implement counterfactual comparisons of densities. The proposed methodology is used to investigate the gender wage gap in Italy. We find that, when sample selection is taken into account, the gender wage gap widens, especially at the bottom of the wage distribution.     

The impact of cognitive skills on the distribution of the black-white wage gap

In this paper we use a semi-parametric estimation procedure to examine differences in the distribution of wages for black and white male workers in the US. In keeping with recent studies we find that differences in cognitive skills are an important determinant of the black-white wage gap and can explain almost the entire male racial wage gap among high wage workers. However, we find that equalising the distribution of cognitive skills will be less successful in reducing this gap at the lower end of the distribution.     

Can consumers continue to lean against the real wage squeeze?

This has been no ‘normal’ consumer recovery. The emphasis on rising employment levels, rather than wage growth, to drive the improvement in real incomes means that while the collective spending power of UK households has strengthened, many individual households continue to feel squeezed. A tightening labour market and emerging skills shortages will improve workers' wage bargaining power, but progress will be gradual and, for many workers, limited by the impact of further strong growth in the labour supply. Therefore, with little scope for households to further reduce the share of income saved, consumer spending growth is likely to remain relatively subdued, lagging well behind the growth rates achieved over the decade prior to the financial crisis.     

Convergent and divergent country trends in coordinated wage setting and collective bargaining in the public hospitals sector

Drawing on the findings of research in the public hospitals sector in five European countries 1 —France, Germany, the Netherlands, Norway and the UK—this article assesses the character of change in wage setting and collective bargaining. It demonstrates the diversity of national arrangements by comparing key characteristics: (i) the bodies of collective representation (unions, professional associations and employer bodies); (ii) the degree of integration with the wider public sector framework; (iii) coordination (or competition) with the private hospitals sector; and (iv) the practice of à la carte provisions within individual hospitals. Despite national varieties of wage setting and collective bargaining, each country sector faces similar tensions—most notably the opposition between public (labour market) rules and health (product market) rules, and pressures to segment or integrate employment conditions by labour force group. By examining the nature of change in institutions for wage setting and collective bargaining in each country, the article contributes to our understanding of the extent of coordination and change of public sector wage setting and describes three scenarios: fragmentation (Germany); continuity (France and the Netherlands); and reconstruction (the UK and Norway).     

Firm heterogeneity and wages in unionised labour markets: Theory and evidence

In many countries wages are set in two stages, where industry-level collective bargaining is followed by firm-specific arrangements determining actual paid wages as a mark-up on the industry wage floor. What explains the wage set in each of these stages? In this paper we show that both the industry wage floor and the average wage cushion are systematically associated with the degree of firm heterogeneity in the industry: The former (latter) is negatively (positively) associated with the productivity spread. Furthermore, since the response of the wage floor dominates that of the wage cushion, workers in more heterogeneous industries tend to get lower actual paid wages. These conclusions are reached in a model of Cournot oligopoly with firm productivity heterogeneity and a two-tiered wage setting system. They are then confirmed by administrative data covering virtually all workers, firms and collective bargaining agreements of the Portuguese private sector for the period 1991–2000.     

Czech female managers and their wages

This paper examines gender gaps in employment and wages among top- and lower-level managerial employees in the Czech Republic at the time of its accession to the EU. Using both least-squares and matching-based decomposition techniques, we find the wage gap among comparable men and women to be sizeable, but quite similar across firm hierarchy levels. The key reason why the average relative wage position of female top managers is worse compared to lower-ranking female employees is that women tend not to be at the helm of the highest-paying companies. Overall, the representation of women at the top of Czech firms as well as the structure of the gender wage gap there appears quite similar to those in the US.     

The transformation of the wage and performance appraisal system in a Japanese firm

This paper analyses how performance appraisal has affected the wages of employees in a unionized Japanese firm over time, using firm-level wage and performance appraisal data. Data show that the wage and performance-appraisal systems have been shifting to a performance basis, and away from the heavy reliance on age and seniority characteristic of the old systems. In the process, wage differentials among employees are becoming wider, particularly among those 37 to 41 years old and those 49 to 55 years old. Management introduced the new wage system through a process of concessionary bargaining. Surprisingly, employees, rather than the enterprise union, were able to convince management to modify their initial plans during bargaining over the new wage system.     

Transnational labour markets and national wage setting systems in the EU

The article analyses the impact of European regulations of posting on different national wage systems. The article shows that the impact varied across the countries and has been filtered by the national institutions regulating the labour market. In the voluntarist wage setting systems of Germany and even Sweden, they have been a major factor bringing wages back into competition. The ability of national actors to act has been considerably curtailed by the European Court of Justice (EUJ), which has placed free competition above the basic rights of autonomous collective bargaining. Because of the divergent interests of Member States, this weakening of national actors cannot be compensated for by transnational agreements. This ‘negative integration’ brings with it a serious risk that the inclusiveness of European wage systems will be eroded by a series of cumulative effects.     

Workers or Employers: Who is Shaping Wage Inequality?

An extensive micro data set matching firms, establishments and their employees, is used to study the determinants of earnings inequality in Portugal and its evolution from 1983 to 1992, with the Theil index, its decomposition, and the decomposition of its change as tools of analysis. The relevance of both worker and employer attributes in shaping earnings inequality and its trend is quantified. The impact of the firm on wage inequality in a European country is compared to the situation in the USA, and the results suggest that a more regulated and centralized European bargaining system might reduce the scope for firm action. A profile of an economy undergoing modernization, where rising labour market inequality signalled the lack of an adequate labour force, can be drawn, with the minimum wage having nonetheless a certain narrowing effect on the earnings distribution.     

The wage policy of firms: comparative evidence for the US and Germany from personnel data

The wage policy of a German firm and a US firm is subjected to a comparative analysis, focusing on the relation between wages and hierarchies. While previous studies have examined only one particular firm, this paper investigates two plants belonging to the same owners with similar production processes but in different institutional environments. Convex wage profiles over the hierarchy levels of both plants are found. The US plant shows considerably higher intensity of intra-firm competition in terms of higher intra-level wage inequality and annual promotion rate. In contrast, wages are more distinctly attached to hierarchy levels in the German firm, as shown by wage regressions. The results are discussed in relation to previous studies.     

The making of the German minimum wage: a case study of institutional change

In the more recent dualistic theories, Germany is cited as an example of a less solidaristic equilibrium, in which ‘producer coalitions’ between core workforces supposedly unaffected by deregulation and their employers prevented the introduction of a minimum wage. The present article shows that such an equilibrium never existed. Core workforces are being threatened by the outsourcing of jobs to the low‐wage sector. This threat created the breeding ground for a joint campaign by manufacturing and service unions for a minimum wage, which made it possible to amalgamate the unions' considerable resources at company level, their strength being derived from the German system of codetermination. Under pressure from the manufacturing unions in particular, the arrangements for the minimum wage follow, as far as possible, the traditions of free collective bargaining. As a result, the social partners in Germany have a considerably stronger influence on the minimum wage than those in the UK.     

Holdup in oligopsonistic labour markets - a new role for the minimum wage

We consider a labour market model of oligopsonistic wage competition and show that there is a holdup problem although workers do not have any bargaining power. When a firm invests more, it pays a higher wage in order to attract workers from competitors. Because workers participate in the returns on investment while only firms bear the costs, investment is inefficiently low. A binding minimum wage can achieve the first-best level of investment, both in the short run for a given number of firms and in the long run when the number of firms is endogenous.
