توضیح
An economic good is a good or service that has a benefit (utility) to society. Also, economic goods have a degree of scarcity and therefore an opportunity cost. This is in contrast to a free good (like air, sea, water) where there is no opportunity cost.
Air is a free good and not an economic good
