The correct answer is Gift economy.
Gift Economy is a type of economy in which goods or services are not sold or bought but data. Relationships, in Gift Economy, are always reciprocal, which guarantees an unceasing circularity of exchanges, called “gift and contradom”. Therefore, another translation for the term is “Economy of the Gift”. It is worth remembering that in Gift Economy the exchange is never monetary and is based on intangible values such as sense of contribution and community.
