This is an alternative method of summarizing the degree to which an industry is oligopolistic and the relative concentration of market power held by the largest firms in the industry. The Herfindahl index gives a better indication of the relative market control of the largest firms than can be found with the four-firm and eight-firm concentration ratios.

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.
