Social capital is "the networks of relationships among people who live and work in a particular society, enabling that society to function effectively". It involves the effective functioning of social groups through interpersonal relationships, a shared sense of identity, a shared understanding, shared norms, shared values, trust, cooperation, and reciprocity. Social capital is a measure of the value of resources, both tangible (e.g., public spaces, private property) and intangible (e.g., actors, human capital, people), and the impact that ideal creators have on the resources involved in each relationship, and on larger groups. Some have described it as a form of capital that produces public goods for a common purpose, although this does not align with how it has been measured. Social capital has been used to explain the improved performance of diverse groups, the growth of entrepreneurial firms, superior managerial performance, enhanced supply chain relations, the value derived from strategic alliances, and the evolution of communities. History While it has been suggested that the term social capital was in intermittent use from about 1890, before becoming widely used in the late 1990s, the earliest credited use is by Lyda Hanifan in 1916 (see 20th century below). The debate of community versus modernization of society and individualism has been the most discussed topic among the founders of sociology: such theorists as Tönnies (1887), Durkheim (1893), Simmel (1905), Weber (1946) were convinced that industrialisation and urbanization were transforming social relationships in an irreversible way. They observed a breakdown of traditional bonds and the progressive development of anomie and alienation in society. 18th–19th century The power of community governance has been stressed by many philosophers from antiquity to the 18th century, from Aristotle to Thomas Aquinas, and Edmund Burke. This vision was strongly criticised at the end of the 18th century, with the development of the idea of Homo Economicus and subsequently with rational choice theory. Such a set of theories became dominant in the last centuries, but many thinkers questioned the complicated relationship between modern society and the importance of old institutions, in particular family and traditional communities. The concept that underlies social capital has a much longer history; thinkers exploring the relation between associational life and democracy were using similar concepts regularly by the 19th century, drawing on the work of earlier writers such as James Madison (The Federalist Papers) and Alexis de Tocqueville (Democracy in America) to integrate concepts of
