Elasticity: The real stretch play. We have all heard the phrase‚ “Stretch your dollar”‚ but have you ever stopped to consider what all goes on behind the scenes in order to make this stretch occur? What rules of economics and finance play into making your hard-earned dollar stretch to its maximum value? While the topic of stretching your money spans across all areas of business‚ finance‚ and economics‚ I will focus on the fundamental principle of economic stretch; elasticity. Elasticity in economics

Demand Estimation After studying this chapter‚ you should be able to: 1. Discuss how the firm’s managers use the information about demand for its product to determine correctly its profit-maximizing rate of output and price‚ or whether to produce a particular product at all. 2. Discuss demand respond to consumer income increase or decrease as a result of an economic expansion or contraction. 3. Specify the components of a regression model that can be used to estimate a demand equation. 4. Interpret

If EG‚S < 0‚ then S and G are inversely related. If EG‚S = 0‚ then S
