there was an excess of males. The theory that has stimulated the most empirical investigation links the existence of polygyny to the productive value of the woman. According to this theory, the occurrence of polygyny is positively related to the extent to which women contribute to the subsistence bases of their respective societies (Pasternak 1976). However, further research suggests that the relationship between womens economic contribution and marriage form is more complex and that there exists a curvilinear relationship between womens productive value and the existence of polygyny (Rosaldo 1974). Polygyny has been found to be a feature of economic systems where potential female contribution to subsistence is high (such as in gathering and agricultural economies). In many African communities, the chief derives his wealth from the plurality of his wives, who by means of the produce of their agricultural labor enable him to exercise the lavish hospitality upon which so much of his power rests. The practice has also been found in economic systems, however, where potential female contribution is low (such as hunting and fishing economies). It has been suggested that multiple wives are valued in the first instance, for economic reasons, while in the latter instance, they are valued for reproductive reasons in that the taking of multiple wives maximizes the potential to produce sons, who in turn make an economic contribution (Malinowski 1962). A multitude of wives, however, may increase not only a mans wealth but also his social importance, reputation and authority, apart from the influence of the number of his children. Hence, we find in many Bantu communities of Africa that the desire to have many wives is one of the leading motives in the life of every man; while the fact that in many Melanesian and Polynesian communities, polygyny is a prerogative and therefore the chief testifies to the social prestige attaching to it (Priso).
