Editing Social exchange theory (section)

===Homans===
Even though Homans took an [[individualistic]] approach, a major goal of his work was to explicate the micro-foundations of social structures and social exchange. By studying such forms of behavior he hoped to illuminate the informal sub-institutional bases of more complex social behavior, typically more formal and often institutionalized.<ref name=Cook/> According to Homans, [[social structures]] emerge from elementary forms of behavior. His vision of the underpinnings of social structure and institutional forms is linked to the actions of individuals, for example to their responses to rewarding and punishment circumstances.<ref>{{cite journal |last1=Cook |first1=K.

Homans developed five key propositions that assist in structuring individuals' behaviors based on rewards and costs. This set of theoretical ideas represents the core of Homans's version of social exchange theory.<ref name=Cook/>
*The first proposition: the success proposition states that behavior that creates positive outcomes is likely to be repeated.
* The second proposition: the stimulus proposition believes that if an individual's behavior is rewarded in the past, the individual will continue the previous behavior.
*The third proposition: the value proposition believes that if the result of a behavioral action is considered valuable to the individual, it is more likely for that behavior to occur.
*The fourth proposition: the deprivation-satiation proposition believes that if an individual has received the same reward several times, the value of that reward will diminish.
*The fifth proposition discusses when emotions occur due to different reward situations. Those who receive more than they expect or do not receive anticipated punishment will be happy and will behave approvingly.<ref name=Cook/>
