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.

A Tycoon Of The MUTUAL FUNDS

Winston Smythe Kennsington III -- our second-estate financial maestro -- has given me a hot, and I mean REALLY HOT, investment tip. Waldo Industries, the parent company of Waldo's TexMex Taco World, is making plans to expand its franchises. Marketing studies show that people are ripe and ready for Waldo's Super Deluxe TexMex Gargantuan Tacos beyond the confines of Shady Valley. For a minimal investment, I can grab a share of this money-making opportunity. A minimal investment to our Ivy-League friend Winnie is $500,000. Unfortunately my bank account, including recent deposits of loose change found on our pedestrian trek, is a few zeros short. Is this another sure-fire financial opportunity that will pass me by?

This isn't me! What am I?
