In this paper I will discuss the basic findings of ‘Workers’ Self-Management and Participation in Decision Making as a Factor of Socioeconomic Changes and Economic Development in Developing Countries,’ an international research project which focused on issues of participation and self-management in several developing countries.2 First, I will show the evolution of workers’ participation and selfmanagement in these countries. This will be followed by the analysis of the practice of participation and self-management, both in the domain of the real workers’ participation in the decision-making and regarding the economic efficiency of enterprises under workers’ participation and self-management.
