The Social Economic Lab (SEL) critically analyzes social problems such as social risks and income polarization exposed in the course of rapid economic growth and development of capitalism. The SEL also seeks the possibility of a 'social economy' as a mechanism for realizing harmony between economic and social values. Specifically, the SEL explores various theories and historical backgrounds related to 'social economy' in order to identify social economic models that fit into the context of each country. On top of its research works, the SEL proposes policy alternatives for realizing a social economy for Korean society.
