The Organisation for Economic Co-operation and Development (OECD) defines sectors differently, depending on the purpose. A sector can be a grouping of institutions, such as government (taxing authority), business (taxable profit-making), philanthropy (untaxed nonprofit), and household (taxable personal income). However, due to increasingly hybridized institutions within the social economy, their categorization may not clearly fit within the social enterprise compass. Designation may depend upon legal and financial structures, as well as the organization's purpose and goals. Policy makers may need to shift legal boundaries to adapt to this dynamic social economy.
