Answer:
benefits; costs
Step-by-step explanation:
The theory of social exchange proposes that all relationships are formed, maintained, or broken due to a cost-benefit analysis. It leads us to make comparisons of alternatives raised and, finally, to opt for those relationships that offer us a greater benefit at a lower cost.
This theory has been highly valued among behaviorist paradigms in that it can be quantified and measured for its simplicity. Over time, and with the emergence of cognitive and constructivist paradigms, it became obsolete.
