The concept *capital* began with the consideration of the factors of production (Land (L) Labor or work (W) Capital (C)). Time goes by, many authors present social and human capital.
Lindon J. Robison et al, tell that social capital is abiding, flexible, fungible. It´s a ressource that people obtain from others. Human capital is a personal resource like skills, experience. Reading some papers i ever see they include motivation in human capital. I call for suggestions
