tailieunhanh - Lecture note Public finance (10th Edition) - Chapter 16: Efficient and equitable taxation

In this chapter, the following content will be discussed: Optimal tax theory uses the tools of welfare economics to provide another view of the efficiency and equity considerations of tax design. In general, taxes: Should have horizontal and vertical equity, should be neutral concerning economic incentives, should be administratively easy, should have low compliance costs. | EFFICIENT AND EQUITABLE TAXATION Chapter 16 Optimal Commodity Taxation w(T – l) = PXX + PYY wT = PXX + PYY + wl wT = (1 + t)PXX + (1 + t)PYY + (1 + t)wl 1 wT = PXX + PYY + wl 1 + t 16- The Ramsey Rule X per year PX DX P0 X0 c P0 + uX b X1 ∆X a Excess Burden P0 + (uX + 1) f X2 i ∆x e j h g Marginal Excess Burden marginal excess burden = area fbae = 1/2∆x[uX + (uX + 1)] = ∆X 16- The Ramsey Rule Continued change in tax revenues = area gfih – area ibae = X2 – (X1 – X2)uX marginal tax revenue = X1 ∆X marginal tax revenue per additional dollar of tax revenue = ∆X/(X1 - ∆X) marginal tax revenue per additional dollar of tax revenue for good Y = ∆Y/(Y1 - ∆Y) To minimize overall excess burden = ∆X/(X1 - ∆X) = ∆Y/(Y1 - ∆Y) therefore 16- A Reinterpretation of the Ramsey Rule inverse elasticity rule 16- The Corlett-Hague Rule In the case of two commodities, efficient taxation requires taxing commodity complementary to leisure at a relatively high rate | EFFICIENT AND EQUITABLE TAXATION Chapter 16 Optimal Commodity Taxation w(T – l) = PXX + PYY wT = PXX + PYY + wl wT = (1 + t)PXX + (1 + t)PYY + (1 + t)wl 1 wT = PXX + PYY + wl 1 + t 16- The Ramsey Rule X per year PX DX P0 X0 c P0 + uX b X1 ∆X a Excess Burden P0 + (uX + 1) f X2 i ∆x e j h g Marginal Excess Burden marginal excess burden = area fbae = 1/2∆x[uX + (uX + 1)] = ∆X 16- The Ramsey Rule Continued change in tax revenues = area gfih – area ibae = X2 – (X1 – X2)uX marginal tax revenue = X1 ∆X marginal tax revenue per additional dollar of tax revenue = ∆X/(X1 - ∆X) marginal tax revenue per additional dollar of tax revenue for good Y = ∆Y/(Y1 - ∆Y) To minimize overall excess burden = ∆X/(X1 - ∆X) = ∆Y/(Y1 - ∆Y) therefore 16- A Reinterpretation of the Ramsey Rule inverse elasticity rule 16- The Corlett-Hague Rule In the case of two commodities, efficient taxation requires taxing commodity complementary to leisure at a relatively high rate 16- Equity Considerations Equity implications of inverse elasticity rule Vertical equity Optimal departure from Ramsey Rule 16- Application: Taxation of the Family Under federal income tax law, fundamental unit of income taxation is family Is excess burden minimized by taxing each spouse’s income at same rate?
