Unformatted text preview: Chapter 8 Application: The Costs of Taxation WHAT’S NEW IN THE THIRD EDITION: There have been no substantial changes to this chapter. LEARNING OBJECTIVES: By the end of this chapter, students should understand: how taxes reduce consumer and producer surplus. the meaning and causes of the deadweight loss from a tax. why some taxes have larger deadweight losses than others. how tax revenue and deadweight loss vary with the size of a tax. CONTEXT AND PURPOSE: Chapter 8 is the second chapter in a three-chapter sequence dealing with welfare economics. In the previous section on supply and demand, Chapter 6 introduced taxes and demonstrated how a tax affects the price and quantity sold in a market. Chapter 6 also described the factors that determine how the burden of the tax is divided between the buyers and sellers in a market.

A tax on a good reduces the welfare of buyers and sellers of the good, and the reduction in consumer and producer surplus usually exceeds the revenue raised by the government. The fall in total surplus —the sum of consumer surplus, producer surplus, and tax revenue—is called the deadweight loss of the tax. 2. Taxes have deadweight losses because they cause buyers to consume less and sellers to produce less, and this change in behavior shrinks the size of the market below the level that maximizes total surplus. Because the elasticities of supply and demand measure how much market participants respond to market conditions, larger elasticities imply larger deadweight losses....
