OLIGOPOLY, CONCENTRATION: Oligopoly is a market structure that contains a small number of relatively large firms, meaning oligopoly markets tend to be concentrated. A small number of large firms account for a majority of total output. Concentration unto itself is not necessarily bad, but it often leads to inefficient behavior, such as collusion and nonprice competition. Concentration is measured in three ways--market share, concentration ratio, Herfindahl index.

DERIVATION, SAVING LINE: A saving line, a graphical depiction of the relation between household sector saving and income, can be derived from the consumption line. The saving line can also be derived by plotting the saving-income information from a saving schedule or using the slope and intercept values of the saving function. However, derivation from the consumption line emphasis the connection between consumption and income--that the household sector uses a portion of income for consumption and a portion for saving.

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.
