ENTRY BARRIERS: Institutional, government, technological, or economic restrictions 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.

ALLOCATION EFFECT

A change in the allocation of resources caused by placing taxes on economic activity. By creating disincentives to produce, consume, or exchange, taxes generally alter resource allocations. The allocation effect is typically used when governments seek to discourage the production, consumption, or exchange of particular goods or activities that are deemed undesirable (such as tobacco use or pollution). This is one of two effects of taxation. The other (primary) is the revenue effect, which is the generation of revenue used to finance government operations.

"We tend to forget that happiness doesn't come as a result of getting something we don't have, but rather of recognizing and appreciating what we do have."
