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.     

Does Rent‐sharing Profit Female and Male Workers? Evidence from Israeli Matched Employer–Employee Data

This paper analyses the impact of workplace characteristics on individual wages based on a unique cross‐section matched employer–employee data set for the Israeli private manufacturing sector in 1995. Specifically, we examine the effects of the interaction between profit‐sharing and wages on the gender wage gap. The empirical findings show that individual compensation is significantly and positively correlated with firms’ profits‐per‐employee, even when controlling for all of the following: group effects in the residuals, individual and firms’ characteristics, industry wage differentials and endogeneity of profits. Wage–profit elasticity is found to be 11 per cent and it does not significantly differ between genders. With respect to the overall gender wage gap (on average women earn 28 per cent less than men), the results show that within firms there is no gender discrimination and that 12 per cent of this gap can be explained by the wage–profits profile and by the fact that women are more likely to be employed in less profitable firms than men.     

Do We Need Computer Skills to Use a Computer? Evidence from Britain

Abstract. Using cross‐section data from the 1997 Skills Survey of the Employed British Workforce, we examine the labour‐market returns to self‐assessed computer skills in Britain. Many researchers, using information on computer technology use, have concluded that wage differentials between computer users and non‐users might, among others, be due to differences in the embodiment of computer skills. Using unique information on the importance, level of sophistication, and effectiveness of computer technology use, we show that computer skills do not yield significant labour‐market returns for most types of use. Examining the returns to computer skills at different levels of sophistication of use yields estimates suggesting returns to computer skills at the highest level of sophistication of use only.     

Labour Market Institutions and the Gender Wage Gap in Britain and Australia, 1973–90

The importance of wage structure is frequently interpreted as indirect evidence of the role played by labour market institutions. The current paper follows in this tradition, examining the role of wage structure in explaining the trend in the gender wage gap over the period 1973–91 for both Australia and the UK. The focus is upon whether changes in wage structure (and associated gender wage gap) both across country and over time are compatible with institutional explanations. Combining comparisons both cross‐country and over time yields a more stringent, albeit indirect, test of the role of institutions.     

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.     

Discriminatory Barriers and the Gender Wage Gap in France

Abstract. In this paper, we propose a method of decomposition that identifies the wage effect of the gender discriminatory barriers in the allocation of grades and full‐time jobs. Standard decomposition techniques tend to interpret the explained portion as a non‐discriminatory component, though discriminatory barriers in the labour market also affect the characteristics of individuals. Using survey data generated by INSEE in France in 2000, we find some evidence that the gender discriminatory barriers within the French labour market explain much of the difference between men and women's attainment and full‐time employment. Our method substantially changes the traditional empirical conclusions since the discriminatory barriers in the allocation of grades and full‐time jobs account for one quarter of the gender monthly wage gap. When adding to the pure wage discrimination portion, we thus show that half of the gender monthly wage gap is not explained.     

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.     

Wage Discrimination and Female Occupational Intensity

The analysis presented in this paper attempts to shed some light, in the context of the Italian labour market, on wage based gender discrimination effects and on the potential impact of gender occupational distribution on wage determination. The results obtained provide some useful insights for Equal Pay legislation and on the efficacy of Comparable Worth (CW) type policies. The wage equation estimates are broadly in line with results obtained elsewhere in the literature. A discrimination effect of nearly 17|X% results when an exclusively male occupational structure is considered. The gender wage gap showed to decrease as female intensity increases. In terms of the framework used, two competing interpretations have been proposed and their implications discussed. The implication of different policy measures which, in recent years, generated much discussion among scholars and in political arenas have been considered, namely: CW and Affirmative Action (AA) policies. Future research should consider a structural model of discrimination so as to discriminate between competing models and policy options.     

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.     

Trade and Labour Markets: Vertical and Regional Differentiation in Italy

The labour market misfortunes of the less skilled and rapid growth of international trade in manufactured goods with less advanced countries are linked by the paradoxical observation that trade theorists are in the forefront of those denying the importance of trade in income distribution. This paper analyses this conclusion by stressing the importance of vertical differentiation of trade flows and regional differentiation of skills in order to identify labour market effects of trade integration. Vertical and regional differentiation in trade and labour markets are analysed for a country, Italy, where these two elements seem to play a crucial role. The results show a likely displacement effect on unskilled labour due to trade flows with less advanced countries. Given the characteristics of Italian trade and labour markets, a stronger trade‐induced displacement effect on demand for unskilled labour takes place in the North of the country. Thus the vertical differentiation in Italian intra‐industry trade is a warning against understating the effect of trade on labour markets if product heterogeneity is not adequately considered. The regional differentiation of skill intensity is another warning against understating the effect of trade on labour markets whenever cross‐sectoral effects and the change in relative specialization are not adequately considered.     

Labour Institutions and Economic Growth: a Survey and a “Regulationist” Approach

Abstract. The paper argues that it is detrimental to assume perfect competition and total flexibility of labour markets in order to understand the intensity and stability of growth. Whereas development theories emphasize the impact of imperfect labour markets, this is not so for modern endogenous growth theories. By contrast, the régulation approaches (in the French meaning) both theoretically and empirically suggest that the transformations in labour institutions might have played a crucial role in the post World War II boom: an unprecedented division of labour associated with long-run labour relations contracts have enhanced the genuine Fordist growth model. Furthermore, international comparisons among OECD countries suggest that job regulations and active minimum wage policies may have created some short-run disequilibria but have stimulated dynamic efficiency, via more technological and organizational innovations. Consequently, this area requires more active researches by labour economists.     

Short-Run Wage Flexibility and Labour Market Adaptation in Western Europe

ABSTRACT: This paper starts by reviewing some of the evidence relating to movements in relative wages, asking what have been their causes and whether they serve to allocate labour across labour markets. Much of the research has tended to focus on the statistical sources available, and therefore to focus on movements of pay between industries rather than firms, between occupations, and between workers with different levels of qualification. This has greatly constrained the possibility of linking these different dimensions to look at the ideal question, namely to what extent do relative wages respond to labour supply and demand pressures, and to what extent do they help to reconcile these two pressures. In addition, evidence from studies based on data obtained from individual firms also broadly supports the view that wage differentials are not very responsive to supply and demand pressures, and also that they are mostly not very effective in promoting the adaptation of labour supply and demand across labour markets. The paper ends by considering briefly some recent policy ideas for increasing the responsiveness of relative wages to demand changes.     

Is There a Double‐Negative Effect? Gender and Ethnic Wage Differentials in Italy

This paper investigates the gender and ethnic wage differentials for female migrants in Italy by applying the Oaxaca–Blinder decomposition, with and without Heckman correction, to account for self‐selection into the labour market. The gender wage gap is nearly 15 per cent, more than 60 per cent of which is unexplained by observable differences. The ethnic wage gap is much larger (39 per cent), but endowments explain 53 per cent of the gap. We also estimate the double‐negative effect of being both female and a migrant. A female migrant earns 42 per cent less than an Italian male; the unexplained component is estimated to be 53–65 per cent. Results are robust to different specifications.     

The Male–Female Wage Gap and the Firm Effect: The Case of Young Italian Workers

Abstract. The idea that wages are determined by firm and individual characteristics suggests that there is a firm effect that influences wage differentials. This paper presents the results of an empirical analysis of gender wage differentials — based on INPS data for people between the ages of 20 and 25 employed in the private sector in 1996 — which takes into account the characteristics of workers and firms using a two‐level random‐effects model. Firm variables proved to be significant, and the proportion of females in the firm showed a negative effect on the wages of both men and women.     

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 Gender Wage Gap in the Turkish Labor Market

Abstract. This paper examines the sources of the gender wage gap in the Turkish labor market by using matched employer–employee data and the standard wage regression estimations as well as the Oaxaca decomposition method. The extensive number of variables in the data set enables a thorough quantitative analysis of the role of various individual‐ as well as firm‐related factors leading to wage differentials between men and women, namely human capital endowments including job tenure, occupational and industrial segregation, private/public sector location, coverage of the workplace under collective labor bargaining, and firm size. It also examines the extent of gender‐based industry and occupational segregation within the confines of data set and computes the Duncan & Duncan segregation index. We find that a large portion of the gender wage gap is attributable to women's considerably lower levels of work experience and job tenure. Other important variables that lead to pay differentials are women's lower concentration in jobs covered by collective labor bargaining and a substantial degree of occupational and industrial segregation. The differential rates of return to many of the wage determinant variables are also found to be significant in the formation of the gender wage gap.     

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.     

Labour Policy and Determinants of Employment and Wages in a Developing Economy with Labour Shortage

Using data from a sample of 1,099 workers, this paper investigates the determinants of employment and wages for workers in the United Arab Emirates. The paper further examines the wage distribution and the decomposition of the wage gap between the public and the private sectors. Results of the study are consistent with the dual labour market theory and indicate that the labour market in the United Arab Emirates is segmented based on sectors (public versus private) and types of workers (nationals versus non‐nationals). The study concludes with a discussion of the implication of these findings for the effectiveness of labour and economic policy.     

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.
