The Regional Dimension of Collective Wage Bargaining: The Case of Belgium

The potential failure of national industry agreements to take into account productivity levels of least productive regions has been considered as one of the causes of regional unemployment in European countries. Two solutions are generally proposed: the first, encouraged by the European commission and the OECD, consists in decentralising wage bargaining to the firm. The second solution, the regionalisation of wage bargaining, is frequently mentioned in Belgium or in Italy where regional unemployment differentials are high. The objective of this paper is to verify if the Belgian wage setting system, where industry bargaining has a national scope, indeed prevents regional productivity levels to be taken into account in wage formation. Using a very rich linked employer-employee dataset which provides detailed information on wages, productivity, and worker's and firm's characteristics, we find that regional wage differentials and regional productivity differentials within joint committees are positively correlated. Moreover, this relation is stronger (i) for joint committees where firm-level bargaining is relatively frequent and (ii) for joint committees already sub-divided along a local line. We conclude that the current Belgian wage setting system (which combines interprofessional, industry and firm level bargaining) already includes mechanisms that allow regional productivity to be taken into account.wages, collective bargaining, federalism, regions, Belgium

Industry wage differentials, unobserved ability, and rent-sharing : Evidence from matched worker-firm data, 1995-2002

This paper investigates inter-industry wage differentials in Belgium, taking advantage of access to a unique matched employer-employee data set covering the period 1995-2002. Findings show the existence of large and persistent wage differentials among workers with the same observed characteristics and working conditions, employed in different sectors. The hypothesis that workers with better unmeasured abilities are over-represented in high-wage sectors may not be rejected on the basis of Martins’ (2004) methodology. However, the contribution of this explanation to the observed industry wage differentials appears to be limited. Further results show that ceteris paribus, workers earn significantly higher wages when employed in more profitable firms. Our instrumented wage-profit elasticity stands at 0.063 and Lester’s range of pay is about 41 per cent of the mean wage. This rent-sharing phenomenon accounts for a large fraction of the industry wage differentials. We find indeed that the magnitude, dispersion and significance of industry wage differentials decreases sharply when controlling for profits.Industry wage differentials; Unobserved heterogeneity; Rent-sharing; Matched employer-employee data; Quantile regressions

Inter-Industry Wage Differentials and the Gender Wage Gap: Evidence from European Countries

This study analyses the interaction between inter-industry wage differentials and the gender wage gap in six European countries using a unique harmonised matched employeremployee data set, the 1995 European Structure of Earnings Survey. Findings show the existence of significant inter-industry wage differentials in all countries for both sexes. While their structure is quite similar for men and women and across countries, their dispersion is significantly larger in countries with decentralised bargaining. Further results indicate that industry effects on the gender wage gap fluctuate sharply across European countries. In particular, our results show that combined industry effects explain 29 per cent of the gender wage gap in Ireland.

Wages and the Bargaining Regime under Multi-level Bargaining: Belgium, Denmark and Spain

We use a harmonized matched employer—employee dataset to study the impact of the collective bargaining regime on wages in the manufacturing sector in three countries with a multi-level system of bargaining: Belgium, Denmark and Spain. Single-employer bargaining has a positive effect both on wage levels and on wage dispersion in Belgium and in Denmark. In Spain, it also increases wage levels but reduces wage dispersion. Our interpretation is that in Belgium and Denmark, single-employer bargaining is used to adapt pay to the specific needs of the firm while, in Spain it is mainly used by trade unions in order to compress the wage distribution
