2. 19-2 I’ll probably kick myself for having said this, but when are we going to have the courage to point out that in our tax structure, the corporation tax is very hard to justify? President Ronald W. Reagan

3. 19-3 Corporations  Corporation – A state-chartered form of business organization, usually with limited liability for shareholders (owners) and an independent legal status  Limited liability  Corporations are “artificial legal persons”

4. 19-4 Why Tax Corporations?  Only real people can pay a tax  Justifications Corporations are distinct entities Corporations receive special privileges from society Protects integrity of personal income tax

5. 19-5 Structure Revenue - Expenses incurred earning revenuesExpenses incurred earning revenues Taxable Income * Tax rate (15% - 35%) Tax - Credits Total Tax Alternative Minimum Tax Treatment of Losses

10. 19-10 Effects on Behavior-Type of Asset  Tax system encourages purchase of assets that receive relatively generous depreciation allowances

11. 19-11 Effects on Behavior-Corporate Finance  Why do firms pay dividends? Dividends as a signal of firm’s financial strength Clientele effect  Effect of taxes on dividend policy Empirical evidence – Chetty and Saez [2004]  Effect on savings  Debt versus Equity Finance  Did the tax system cause the corporate accounting scandals?

22. 19-22 General Analysis of Depreciation Tax Savings T = tax life D(n) = proportion of asset that can be written off against taxable income in nth year θ = corporate tax rate Present value of tax savings: ψ = θ * D(1) + θ * D(2) + … + θ * D(T) 1 + r (1 + r) 2 (1 + r) T

23. 19-23 More on Depreciation  Accelerated depreciation  Expensing  Intangible Assets

24. 19-24 Investment Tax Credit k = investment tax credit q = acquisition price of asset (1 – k)q = effective price of asset

25. 19-25 Stiglitz Model G = before-tax value of output produced by machine r = interest rate Firm buys machine if: G – r > 0 Assume corporate tax (1) net income taxed at rate θ (2) net income = G – r (1 – θ)(G – r) > 0

26. 19-26 Neoclassical Model User cost of capital = (r + δ) After tax rate of return = (1 – θ) * (1 – t) (1 – θ) * (1 – t) * C = (r + δ) C = (r + δ) (1 – θ) * (1 – t) C = (r + δ) * (1 – ψ –k) (1 – θ) * (1 – t)

27. 19-27 Effect of User Cost on Investment  Econometric problems Role of expectations Elasticity of supply curve of capital goods Open economy problems

28. 19-28 Cash Flow Model  What is cash flow?  Irrelevancy of cash flow in neoclassical model  Cost of internal versus external funds  Empirical results

29. 19-29 Maximization of World Income r f = r US (1 – t f )r f = (1 – t US )r US Full credit versus limited credit

30. 19-30 Maximization of National Income (1 – t f )r f = r US r f = r US /(1 – t f ) if t f < 1, then r US < r US /(1 – t f ) Deduction of foreign tax payments from domestic income: r f (1 – t f )(1 – t US ) = r US (1 – t US ) Note: this equation equivalent to … this one

31. 19-31 Effects on Efficiency of Full Integration  Misallocation of resources between corporate and noncorporate sectors eliminated  Tax-induced distortions in savings decisions reduced  Remove incentive for “excessive” retained earnings  Reduce bias toward debt financing
