In general terms, reciprocity is the process of exchanging things with others with the objective of gaining mutual benefit. Reciprocity is a social norm where one feels obligated to return the favour to someone that has done something to them. This is a socialization process that is essential in the development of the requirement to give in return. Children are more often involved in reciprocal actions than adults. This is essential for their development and continued associations.
Well, balanced reciprocity is a process where the value of the exchange is calculated and the favour returned in equal measure and within a particular period of time. Therefore, people exchange things or items that are considered of the same value.
