Social Exchange Theory was created by George Homans in 1958. Since its publication as “Social Behavior as Exchange”, many other theorists such as Peter Blau, Richard Emerson, John Thibaut and Harold Kelley contributed to the theory. Before delving into the most important concepts of this theory, it is necessary to discuss two main properties. This theory is about social exchanges, which are essentially reactions and decisions in relationships. The two properties are self-interest and interdependence. They are the two fundamental interactions between two individuals who each have something of value to the other. When an individual seeks their own self-interest, they also seek their own economic and psychological needs which can result in things like greed and competition. However, self-interest is not seen as a bad thing; in fact, it can lead both parties to realize their interests. Interdependence, on the other hand, is more difficult to study but is the combination of the two using the efforts of both to achieve something. Interdependence has higher social implications. Homans, as the founder of the theory, had it said that the theory consists of a social exchange with rewards and costs between at least two people. Rewards are defined as objects that have positive value and are sought after by individuals. Costs are defined as objects that have a negative value and are avoided by individuals. Relationship rewards are things like support, friendship, and acceptance, while costs are things like energy expended, time, and money. Essentially this theory states that each individual tries to maximize their wins or value and ends up with something that is more positive than negative. Worth... half of paper ......omans, G. C.
