It has long been recognised that individuals and communities choose to associate and meet their needs for goods and services through institutions other than states, markets or households. During the last quarter of the twentieth-century, however, there have been increasingly formalised attempts to organise the study of these institutions through the development of a language and set of theories which delineate a distinctive sector (Hall, 1992). The problem has been that a new scholars enter the field they have brought alternative definitions of the subject area with them. Institutions which are neither statutory, nor profit maximising, have been collectively and variously called the voluntary, third, non-profit, or more recently, civil society, sector. Scant attention has been given to how these various and competing definitions relate to one another (Lohmann, 1992). Which institutions should be ruled in, or out, of these over-lapping, but potentially different sectors?
