Neo-Institutionalist Economics is a school of developmental thinking that purports to explain the history, existence, and functions of a wide range of institutions (whether government, the law, markets, the family, and so on) according to the assumptions of the neo-liberal economic theory. In that sense, neo-institutionalism represent a variant of the neo-liberal orthodoxy that is ascendant within governments, international development agencies, policy think tanks, and increasingly large section of the social science community.[1]
