Social capital is a form of capital that contributes to productivity, business, and society. It refers to the norms, trust, and networks that form the basis of relationships in business and society. Robert Putnam defined social capital as features of social organization, such as trust, norms, and networks that can improve the efficiency of society by facilitating coordinated actions. Social norms and/or social networks are key elements of social capital, and trust is also a part of it. Social capital is widely seen as a resource that facilitates cooperation within or between groups of people. It can arise in relationships in many areas of life.
