Economics in a Family Way

This paper argues that the economics of the family can be much enriched by incorporating recent developments in evolutionary biology, animal behavior studies, cultural evolution, anthropology, and game theory. Evolutionary foundations of sympathy between relatives are explored. Applications of the theory of cultural evolution to the demographic transition and to wealth transfers between generations are investigated. The economics of marital institutions such as polygyny, polyandry, and matriarchy are discussed, as well as recent work by economists on non-monogamous mating arrangements in our own society. Applications of recent developments in non-cooperative bargaining theory and matching theory to the theory of marriage are presented.
