Discussion Questions 1.Refer to Figure 13.5 in your textbook. Suppose that the demand curve for barley can be characterized by the equation Xd = 26 P/2. Suppose further that price was $10.00 and a $4.00 tax is imposed on the market. a)What is the amount of tax revenue generated by the tax? b)How much excess burden is generated by the tax? 2.Refer to Figure 13.7 in your textbook. If the supply curve for labor can be written as L = w/2 3/2 and the initial wage was $10, how much excess burden is created if there is a tax on wages of $2? 3.Suppose the inverse demand curve for good A is given by the equation PA = 10 QA/10, and the supply curve is perfectly elastic (horizontal) at $1. Good A is presently taxed at $2 per unit. Good B (which is independent of good A) has an inverse demand curve, PB = 5 QB/20, and is also perfectly elastic at $1. Good B is untaxed. a)How much tax revenue is collected and what is the excess burden of the $2 tax on A? b)How much revenue is collected if the tax on good A is reduced to $1 per unit and good B is taxed at $1 per unit? c)What is the total excess burden of taxing both goods at $1 per unit? d)Which tax system is preferable from the point of view of economic efficiency? 4.Suppose that demand is perfectly inelastic. Supply is normal and upward sloping. What is the economic incidence of a unit tax placed on suppliers? 5.Refer to Figure 13.8 in your textbook. If VMPmkt can be characterized by the equation VMPmkt = 50 2Hmkt, where H is the number of hours worked, and VMPhome can be characterized by the equation VMPhome = 45 3Hhome, where H is the number of hours worked, what is H* if there are a total of 40 hours to be worked between work and home? True/False/Uncertain Questions 1.When a single tax is imposed, the excess burden is proportional to the compensated elasticity of demand and to the square of the tax rate. 2.A lump sum tax can create an excess burden. 3.The logic of the double-dividend hypothesis may not hold because the Pigouvian tax exacerbates pre-existing distortions in the labor market. 4.Taxing in labor markets creates more excess burden than taxing in commodity markets. 5.The differential taxation of inputs does not create an excess burden. 6.Lump sum taxes do not distort behavior. 7.Taxes that create an excess burden are bad. 8.Excess burden calculations typically assume no other distortions. 9.Unit taxes vary along with the price of the taxed commodity. 10.Taxes impose an excess burden. Test Bank to accompany Rosens Public Finance, Seventh EditionChapter 13 83 Essay Questions 1.Suppose you had to design an economic system for a country that had never existed before, like one of the former Soviet Union countries. What criteria would you consider to minimize the excess burden of the system of taxation? 2.Equivalent variation is a method employed to measure excess burden. Comment on why a method such as compensating variation would not be appropriate for this analysis. 3.Is it possible to design a tax that does all of the following: i) leaves behavior unchanged so that the quantity demanded of goods and services does not change, ii) creates no excess burden, iii) is not regressive, and iv) is welfare enhancing? Answers to CHAPTER 13 - Taxation and Efficiency Answers to Multiple-Choice Questions 1.a 2.a 3.d 4.e 5.d 6.a 7.a 8.d 9.d 10.c 11.b 12.d 13.b 14.a 15.c Answers to Discussion Questions 1.a)Tax revenue generated is (4)(19) = 76. b)Excess burden is (1/2)(4)(2) = 4. 2.Excess burden is the area of the triangle idh, which is (1/2)(2)(1) = 1. 3.a)Tax revenue = (2)(70) =140. Excess burden = (1/2)(2)(20) = 20. b)Total tax revenue = (1)(80) + (1)(60) = 140. c)Total excess burden = (1/2)(20)(1) + (1/2)(10)(1) = 15. d)Both systems raise the same amount of tax revenue, 140, but the second system does it with less excess burden, 15 20. Therefore, the second system would be more efficient. 4.The economic incidence of the tax falls entirely on the consumers. 5.Setting the two equations equal to each other gives 50 2Hmkt = 45 3Hhome and, keeping in mind the total time constraint, that Hmkt + Hhome = 40 yields that Hhome * = 25 and Hmkt* = 15.
