GOVERNMENT PURCHASES LINE: A graphical depiction of the relation between government purchases and national income (or gross domestic product) that plays a role in Keynesian economics and the Keynesian cross. The slope of this line is positive, greater than zero, less than one, and goes by the name marginal propensity for government purchases. The vertical intercept of this line is autonomous government purchases. The aggregate expenditures line used in the Keynesian cross is obtained by adding this government purchases line, as well as, investment expenditures and net exports, to the consumption line. The government purchases line is also combined with investment expenditures for the Keynesian saving-investment model.

UNIT ELASTIC An elasticity alternative in which changes in one variable (usually price) cause equal proportional changes in another variable (usually quantity). In other words, any change in price, whether big or small, triggers exactly the same percentage change in quantity. Quantity changes match price changes. This characterization of elasticity is most important for the price elasticity of demand and the price elasticity of supply. Unit elastic is one of five elasticity alternatives. The other four are perfectly elastic, perfectly inelastic, relatively elastic, and relatively inelastic.

Getting Your Share Of FARM SUBSIDIESOur pedestrian excursion through the economy has helped me work up a ferocious appetite. I vote for a quick stop at the Mr. Market Super Food Discount Store where we can purchase a loaf of bread, assorted meats, and some cheese -- all for a luncheon tribute to the Earl of Sandwich. While a self-made tribute to the Earl is less expensive than any purchased from Manny Mustard's House of Sandwich, the ingredients from Mr. Market Super Food Discount Store still carry a hefty price tag. If you're hungry and have limited cash on hand, you might wonder whether food prices are higher than they need to be.

[What's This?]
Today, you are likely to spend a great deal of time at a going out of business sale seeking to buy either a small palm tree that will fit on your coffee table or several magazines on fashion design. Be on the lookout for fairy dust that tastes like salt.
