positive reciprocity occurs when an action committed by one individual that has a positive effect on someone else is returned with an action that has an approximately equal positive effect. for example, if someone takes care of another person's dog, the person who received this favor should then return this action with another favor such as with a small gift. however, the reciprocated action should be approximately equal to the first action in terms of positive value, otherwise this can result in an uncomfortable social situation. if someone takes care of another person's dog and that person returns the favor by buying that individual a car, the reciprocated gift is inappropriate because it does not equal the initial gesture. individuals expect actions to be reciprocated by actions that are approximately equal in value.
