Social capital, referring to connections within and between social networks, is a core concept in business, economics, organisational behaviour, political science, public health, and sociology. Though there are in fact a variety of inter-related definitions of this term, which has been described as “something of a cure-all”^[1] for the problems of modern society, they tend to share the core idea “that social networks have value. Just as a screwdriver (physical capital) or a college education (human capital) can increase productivity (both individual and collective), so too social contacts affect the productivity of individuals and groups” (via Wikipedia)
