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.

SERVICE

Activities that provide direct satisfaction of wants and needs without the production of tangible products or goods. Like the related term good, a service is produced using society's resources and represents a fundamental aspect of the economy. Limited resources are used to produce the services that satisfy unlimited wants and needs in an ongoing effort to address the problem of scarcity.

[What's This?]

Today, you are likely to spend a great deal of time looking for a downtown retail store looking to buy either a T-shirt commemorating last Friday (you know why) or a rotisserie oven that can also toast bread. Be on the lookout for deranged pelicans.

This isn't me! What am I?

In his older years, Andrew Carnegie seldom carried money because he was offended by its sight and touch.
"Unless you are willing to drench yourself in your work beyond the capacity of the average man, you are just not cut out for positions at the top."
