Gift economy
Some  things that make gift exhange different from other forms of exhange. Usually, the idea of property, and property rights are different. Sometimes gifting forms a distinct "sphere of exchange" that is  an "economic system". Giving a gift always establishes a social relationship. The nature of giving a gift in a market economy,is very different from  "prestations" typical of non-market societies.  Gift economies also differ from related phenomena, such as common property regimes and the exchange of non-commodified labour.
