Exchange perspective

Explanation: When a relationship is based on the analysis of cost or sacrifice incurred and the benefit one enjoys. The exchange perspective could occur in so many social relationships including friendship and even marriage such as in Jeremiah's case as discussed above. His decision to propose to Yolander is based on analysis of the benefit he stands to gain such a s intelligence, being financially independent, easy going, attractive and so on. and the sacrifice he has to make in the relationship. Since the sacrifice doesn't outweigh the benefit, hence Jeremiah's decision to propose. This kind of relationship evaluation is from an exchange perspective.
