Although the status of trade unions may be very different among states, unions are still a very meaningful compo- nent of labour markets. In this paper, we contribute to the debate about the institutions that may affect the outcome of trade unions in different legal systems. Firstly, we draw on the theoretical underpinnings of trade union activity and density. Then, we conduct an empirical analysis of the relationships between trade union density in a particular country, country’s legal origins and government’s ideology. In this way, the paper enriches an underexploited niche in institutional research devoted to labour market issues. Keywords: institutions, trade unions, legal origin, party ideologies.

Last but not least, trade unions may try to cope (Aidt and Sena 2005).

Indeed, trade premium depends on the way that wages in unionized unions which are representative at the national level sectors spread into those that are non-unionized.
