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

Abstract

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.
