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.

The ease with which an asset can be converted to money with little or no loss of value. Money, currency and checkable deposits, is the benchmark for liquidity. Money is what other assets are converted to. Different assets have differing degrees of liquidity. Financial assets have differing degrees of liquidity but tend to be more liquid that physical assets. Liquidity is important to components of the three monetary aggregates tracked and reported by the Federal Reserve System--M1, M2, and M3.
