SHORT RUN AND LONG RUN

Accounting:

Short and long runis based upon annual chronology.

Economics:

Short runhas fixed plant capacity size.

Long runhas variable plant capacity size.

LONG-RUN PRODUCTION COSTS

For every plant capacity size...

there is a short-run ATC curve.

All such plant capacities

can be plotted.
