“Socioeconomics” is sometimes used as an umbrella term for various areas of inquiry. The term “social economics” may refer broadly to the "use of economics in the study of society".[1] More narrowly, contemporary practice considers behavioral interactions of individuals and groups through social capital and social "markets" (not excluding, for example, sorting by marriage) and the formation of social norms.[2] In the latter, it studies the relation of economics to social values.[3]
