opportunity cost
The value of resources and time given up relative to the best alternative. Includes the estimation of time in process. If a economy is competitive, the opportunity cost is a good indicator of the price because any change in prices is a change in the opportunity cost, which means a change in the allocation of resources.
Example:
The opportunity cost of 9/11 was huge! Lives were lost, capital was destroyed, people got sick......so when 9/11 happened there was a change in the market prices which changed the allocation of resources.
