ENTRY BARRIER: An institutional, government, technological, or economic restriction on the entry of firms into a market or industry. The four primary barriers to entry are: resource ownership, patents and copyrights, government restrictions, and start-up costs. Barriers to entry are a key reason for market control and the inefficiency that this generates. In particular, monopoly, oligopoly, monopsony, and oligopsony often owe their market control to assorted barriers to entry. By way of contrast, perfect competition, monopolistic competition, and monopsonistic competition have few if any barriers to entry and thus little or no market control.

ECONOMIES OF SCALE

Declining long-run average cost that occurs as a firm increases all inputs and expands its scale of production. Economies of scale result from increasing returns to scale and are graphically illustrated by a negatively-sloped long-run average cost curve. Economies of scale usually occur for relatively small levels of production and are then overwhelmed by diseconomies of scale for relatively large production levels. Together, economies of scale and diseconomies of scale create a U-shaped long-run average cost curve.

Your Complete Scope

This isn't me! What am I?

Junk bonds are so called because they have a better than 50% chance of default, carrying a Standard & Poor's rating of CC or lower.
"Anything's possible. You can be told you have a 90% chance or a 50% chance or a 1% chance, but you have to believe, and you have to fight. "
