ARBITRAGE: Buying something in one market then immediately (or as soon as possible) selling it in another market for (hopefully) a higher price. Arbitrage is a common practice in financial markets. For example, an aspiring financial tycoon might buy a million dollars worth of Japanese yen in the Tokyo foreign exchange market then resell it immediately in the New York foreign exchange market for more than a million dollars. Arbitrage of this sort does two things. First, it often makes arbitragers wealthy. Second, it reduces or eliminates price differences that exist between two markets for the same good.

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.
