INDUCED EXPENDITURE: An aggregate expenditure (consumption, investment, government purchases, and net exports) that depends on national income or gross domestic product. These four aggregate expenditures are conveniently separated into two types, induced, which is our current topic of expenditures unrelated to national income or GDP, and autonomous expenditures, expenditures which are unrelated to national income or GDP. Induced expenditures are graphically depicted as the slope of the aggregate expenditures line, and depend in large part on the marginal propensity to consume. The induced relation between income and expenditures form the foundation of the multiplier effect triggered by changes in autonomous expenditures.
