Disequilibrium occurs when supply and demand are out of balance. However, this sometimes never happens to markets or it happens only rarely and momentarily. On the other hand, economists sometimes state that markets are always disequilibrium and that this is just how the market goes, as markets are excess in disequilibrium over extended periods of time.
They would feel more obligated to make decisions based off of the oath they have taken.
