AGGREGATE EXPENDITURE LINE: A line representing the relation between aggregate expenditures and gross domestic product used in the Keynesian cross. The aggregate expenditure line is obtained by adding investment expenditures, government purchases, and net exports to the consumption line. As such, the slope of the aggregate expenditure line is largely based on the slope of the consumption line (which is the marginal propensity to consume), with adjustments coming from the marginal propensity to invest, the marginal propensity for government purchases, and the marginal propensity to import. The intersection of the aggregate expenditures line and the 45-degree line identifies the equilibrium level of output in the Keynesian cross.

LAW OF DEMAND: The inverse relationship between demand price and the quantity demanded, ceteris paribus. This fundamental economic principle indicates that as the price of a commodity decreases, then the quantity of the commodity that buyers are able and willing to purchase in a given period of time, if other factors are held constant, increases. This law is incredibly important to the study of economics. If you compiled a top ten list of economically important laws, the law of demand would be right there at the top.

BENEFIT PRINCIPLE A taxation principle stating that taxes should be based on the benefits received. The benefit principle works from the proposition that those who receive the greatest benefits should pay the most taxes. The benefit principle is commonly used for near-public goods such as highways, libraries, college, and national parks. This is one of two taxation principles. The other is the ability-to-pay principle, which states taxes should be based on income or the ability to pay taxes.
