The CCFs also finance culture, tourism and commercial activities and own supermarkets, theatres, hotels and other facilities. Yet there is little evaluation of the cost-effectiveness of the services the CCFs provide (Aim and Lopez-Castano, 2005). A 2% contribution finances traineeship programmes, in particular for young workers and displaced persons, through the Semcio Nacional de Aprendizaje (SENA). The SENA also finances assistance to firms for technological development and information systems.
