Social Capital,Human Capital and the Community Mechanism: Toward a Conceptual Framework for Economists

For facilitating the development of a consensus on the concept of social capital among economists, this paper proposes its operational definition in a way consistent with the definitions of physical and human capital and discusses the relevance on the use of the metaphor of capital for social capital. Further, the unique characteristics in the production and accumulation of social capital in comparison with physical and human capital are identified in relation with the community which is considered the central mechanism to produce social capital. The merits and drawbacks of the community relative to the market and the state are examined with the aim of identifying the conditions under which social capital can be supplied efficiently in the direction of promoting economic progress.
