Econ 208 MarekKapicka Lecture 11 Redistributive Taxation Ricardian Equivalence
Where are we? • Introduction: A model with no Government • The Effects of Government Spending • Government Taxation and Government Debt • Labor Taxation • Taxation and Redistribution • Government Debt
Taxation and Redistribution • Fiscal policy may aim to change income or consumption inequality • Will have an example when • It is optimal to reduce income inequality even if • A (distorting) flat tax is used • There are costs in terms of production
An example: 2 productivity levels • Two types of people: • Low productivity: wages wL • High productivity: wages wH>wL • ½ of population is of low productivity, ½ is of high productivity • Utility:
Taxes • High productivity people are taxed at rate t • Low productivity people get a transfer v
Low productivity people • Subject to • Solution
High productivity people • Subject to • Solution
Government • Budget constraint: • Express utility as a function of t only: • where k=wH/wL>1
Welfare and Production • Assume that the society’s welfare is given by • Big and controversial assumption! • We have
Welfare and Production • Welfare is maximized at • Production is decreasing in t:
Conclusions • There is a trade-off between efficiency and redistribution • What matters: • How the government weights the utility of different individuals • Distribution of skills in the population
Where are we? • Introduction: A model with no Government • The Effects of Government Spending • Government Taxation and Government Debt • Labor Taxation • Taxation and Redistribution • Government debt
Government Debt • 1) The Data • 2) Ricardian Equivalence Theorem • Gov’t Debt does not matter ! • 3) Ramsey Problem • Find the optimal debt level if taxes are distortionary and RET fails • Read 14.1-14.2 for today, 14.3-14.4 for next week
US Government Debt • As of now: • Privately held US gov’t debt is about 70% of GDP • Total US gov’t debt is about 100% of GDP • US Treasury: monthly statement
Consumers • Budget constraints • Utility
Lifetime wealth • Define lifetime wealth as present value of a disposable income • Then lifetime budget constraint says that present value of consumption is equal to lifetime wealth
Government • Current period budget constraint • Future period budget constraint • Present value budget constraint
Competitive Equilibrium • Consumers choose c,c’,s optimally, given r • Government PVBC holds • Interest rate such that the credit market clears:
Ricardian Equivalence • Suppose the government cuts taxes by $600:
Ricardian Equivalence • You should also get a second letter: • There is no change in your wealth!! Dear Taxpayer: We are sorry to inform you that the present value of your future tax liabilities has increased by the amount of $600.
Ricardian Equivalence Theorem The Ricardian Equivalence Theorem: If all government spending is held constant, then a change in current taxes leaves the equilibrium interest rate and the consumption of individuals unchanged
Ricardian Equivalence with a Cut in Current Taxes for a Borrower
Implications of Ricardian Equivalence • Tax cut is not a free lunch! • Timing of gov’t taxes does not matter • Deficits do not matter!
Failure of Ricardian Equivalence • If people are heterogeneous, they might not be affected equally • Some people may receive larger tax cuts than others and their lifetime wealth may change • That is, there is a redistribution of wealth across people
Failure of Ricardian Equivalence • Debt may not be repaid during the lifetimes of the people who received tax cuts • There is a redistribution of wealth across generations • Example: Social Security
Failure of Ricardian Equivalence • Credit markets are not perfect • People may face borrowing limits. In such case, a tax cut will not be saved • People may face higher interest rate than government. In such case, a tax cut will increase present value of their resources and increase consumption
Failure of Ricardian Equivalence • Taxes are not lump sum • If taxes cause distortions, then timing of taxes does matter • A government may want to spread the distortions across all periods
Example of RI: George Bush, 1992 • George Bush, 1992: change in tax withholding • Taxes were deferred until April 1993 • Total size: $25 billion • Hope: consumers will increase spending • Result: consumption didn't change much • Didn't know Ricardian Equivalence...
