What is the difference between the short run and the long run as economists define the two?
What will be an ideal response?
The short run is a period of time within which at least one resource is fixed. It could be a commitment for a rental lease, for example. The short run is also a period too short for new firms to enter the industry or for firms currently in the industry to exit. For the long-run period, all resources may vary; hence, all costs are variable costs. New firms may enter the industry and old firms may exit.
