In contrast to processes involving commodification, commercialisation, bureaucratisation and corporatisation, the SSE reasserts the place of ethics, social well-being and democratic decision-making in economic activities and governance. Identifying and analysing a myriad of issues and topics associated with the SSE, the Encyclopedia broadens the knowledge base of diverse actors of the SSE, including practitioners, activists and policymakers.
