PERFECT PRICE DISCRIMINATION: A form of price discrimination in which a seller charges the highest price that buyers are willing and able to pay for each quantity of output sold. This is also termed first-degree price discrimination because the seller is able to extract ALL consumer surplus from the buyers. This is one of three price discrimination degrees. The others are second-degree price discrimination and third-degree price discrimination.

DERIVATION, AGGREGATE EXPENDITURES LINE

An aggregate expenditures line, a graphical depiction of the relation between aggregate expenditures and the level of aggregate income or production, can be derived by sequentially adding expenditures by the four macroeconomic sectors (household, business, government, and foreign). This derivation process begins with the consumption line, then adds investment, government purchases, and finally net exports. The process actually generates three alternative aggregate expenditures lines based on the number of sectors included (two sector, three sector, and four sector).
