Industrywide collective bargaining, wages gains and black labour market in Spain.

Abstract

This paper provides an empirical evaluation of the effects of the Spanish industrywide collective bargaining on wages. For this purpose, agreed wages have been computed for individuáis from a subsample of a spanish labour forcé survey and have been compared with their reported wages. A relevant conclusión emerges from this work: sectoral agreements constitute a small intervall of minimum wages binding for semi-skilled and unskilled workers. Meyer and Wise approach is used for estimating unión wage gains due to industrywide bargainings and for testing the presence of "the sword of justice effect" in Spain
