Answer :
Answer:
The Rationality Assumption.
Explanation:
The assumption of rationality is the belief that people will choose something which will increase efficiency from a series of decisions; this advantage is prone to interpretation and it can be based on actual economic profit, benefit to society, and a multitude of other things.
Economists often presume reason when interacting with theory and devising mathematical and statistical models to explain behaviour. It is safe to assume in many cases, such as a straightforward supply / demand model, that people will behave on basic moral standards such as a cap on desire to pay.
