Chapter 5 Elasticity

The concept of elasticity is thoroughly covered in this chapter, from the definition, to the calculation, and finally to the application. Price elasticity of demand is covered first, followed by income and price elasticities. The price elasticity of supply is covered, and the chapter concludes with an analysis of tax burdens based on differences in the price elasticities of demand and supply.

Chapter 6 Overview Consumer Choice and Demand

The analysis of consumer choice in this chapter begins with the consideration of the
budget line. Total and marginal utility are then introduced and discussed, and an
incremental process is detailed through which a hypothetical consumer (and the
students) can see the utility-maximizing combination of two goods. The derivation
of the demand curve is then presented and the chapter concludes with a discussion
of consumer surplus. For instructors who wish to use indifference curves in the
analysis of consumer optimization, a detailed appendix is provided.
