INDUSTRY: A group of firms producing goods or services that are close substitutes-in-consumption. The similarity of the products makes it possible to analyze the production in a market framework. An industry can be broadly defined, such as the manufacturing industry, or narrowly specified, such as the root beer industry. For most economic analysis the term industry is used interchangeably with the term market.

AUTONOMOUS EXPENDITURES Expenditures on aggregate production by the four macroeconomic sectors that do not depend on income or production (especially national income or even gross domestic product). That is, changes in income do not generate changes in these expenditures. Each of the four aggregate expenditures--consumption, investment expenditures, government purchases, and net exports--have an autonomous component. Autonomous expenditures are affected by the ceteris paribus aggregate expenditures determinants and are measured by the intercept term of the aggregate expenditures line. The alternative to autonomous expenditures are induced expenditures, expenditures which do depend on income.
