• Depreciation
– Economic depreciation: The extent to which an asset decreases in value during a period of time
– Accelerated depreciation: Taking depreciation allowances faster than true economic depreciation
• Expensing: deducting the asset’s full cost at time of acquisition
• Tax life: the # of years an asset can be depreciated
– 3, 5, 7, 10, 15, 20, 27.5, and 39 years
– Most 5 years
– Intangibles
• Treatment of Dividends versus Retained Earnings
– Double taxation
19-7

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

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

• Types of Assets
– Tax system encourages purchase of assets that receive relatively generous depreciation allowances
• Total Physical Investment
– Accelerator Model
– Neoclassical Model
– Cash Flow Model
19-14

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)

19-22

• Misallocation of resources between corporate and non-corporate sectors eliminated
• Tax-induced distortions in savings decisions reduced

• The U.S. Corporate Income Tax of 35%, accounting for about 10% of all federal revenues, is controversial due to double taxation arising from the dividend income tax component of the personal income tax
• Economic analysis centers on the effect of the tax on amount of physical investment, dividend income payments, debt financing, state taxes, and tax avoidance, particularly concerning multinational corporations
• Tax reforms include full integration of corporate and personal income taxes, and dividend relief
