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.

PERSONAL INCOME The total income received by the members of the domestic household sector, which may or may not be earned from productive activities during a given period of time, usually one year. Personal income (PI) is one of three measures of income reported in the National Income and Product Accounts maintained by the Bureau of Economic Analysis. The other two are national income (NI) and disposable income (DI). Two related measures of production are gross domestic product (GDP) and net domestic product (NDP). The primary use of personal income is to measure the income actually paid out to the household sector. After adjusting for income taxes, personal income forms the basis for consumption expenditures on gross domestic product.
