When a market is in equilibrium, both buyers and sellers do not perceive a benefit from changing their behavior. Why?

What will be an ideal response?

ANSWER

In most economic situations, an economic agent is not optimizing individually. His decision is influenced by the decisions taken by other economic agents. In equilibrium, each and every economic agent is doing the best that they can do, given the information they have and given the actions of other economic agents. Therefore, nobody perceives a benefit from changing his or her behavior.
