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.

ASSUMPTIONS, KEYNESIAN ECONOMICS The macroeconomic study of Keynesian economics relies on three key assumptions--rigid prices, effective demand, and savings-investment determinants. First, rigid or inflexible prices prevent some markets from achieving equilibrium in the short run. Second, effective demand means that consumption expenditures are based on actual income, not full employment or equilibrium income. Lastly, important savings and investment determinants include income, expectations, and other influences beyond the interest rate. These three assumptions imply that the economy can achieve a short-run equilibrium at less than full-employment production.

"I learned about the strength you can get from a close family life. I learned to keep going, even in bad times. I learned not to despair, even when my world was falling apart. I learned that there are no free lunches. And I learned the value of hard work. " -- Lee Iacocca
