DEMAND ELASTICITY AND TOTAL EXPENDITURE: The notion that price-induced changes in total expenditure for a good (price times quantity) depends on the relative price elasticity of demand. In particular, for relatively elastic demand (1 < E < ∞) changes in price cause total expenditure to change in the opposite direction. An increase in price causes total expenditure to fall and a decrease in price causes total expenditure to rise. For relatively inelastic demand (0 < E < 1) changes in price cause total expenditure to change in the same direction. An increase in price causes total expenditure to rise and a decrease in price causes total expenditure to fall. For unit elastic demand (E =1) price changes do not cause any change in total expenditure. Total expenditure is the same whether price increases or decreases.

Lesson 4: Production Possibilities | Unit 3: The Curve
|
Page: 9 of 24
|
We can transform the schedule of production possibility numbers into a graph.- Each bundle can be represented by a point in two dimensional production possibilities space.
- The two dimensions of the space are clock calibrators on the horizontal axis and jogging shoes on the vertical axis.
- The horizontal axis is measured between 0 and 11 calibrators.
- The vertical axis is measured between 0 and 500 jogging shoes.
- The two axis are joined at the origin.
- The plotted bundles form a semi-circle pattern.
- If these were stars in the night sky we might name it the arc of production. But it's not, so we won't.

AVERAGE REVENUE CURVE, MONOPOLISTIC COMPETITION A curve that graphically represents the relation between average revenue received by a monopolistically competitive firm for selling its output and the quantity of output sold. Because average revenue is essentially the price of a good, the average revenue curve is also the demand curve for a monopolistically competitive firm's output.

[What's This?]
Today, you are likely to spend a great deal of time strolling around a discount warehouse buying club trying to buy either decorative celebrity figurines or a flower arrangement with anything but tulips for your grandfather. Be on the lookout for defective microphones.
