Definition of “Income”
• Haig-Simon: “The increase in person’s ability to consume over a
given period of time”
Income = Consumption + Net Change in Wealth
Would include…
• Wages
• Value of all Employer and Govt benefits
• Capital Income (rent, dividends)
• Capital Gains/Losses (whether realized or not) in real terms.
(appreciate and depreciation).
• Domestic production
• Value of services from owned durable good. (Rental value of own
home, cars, etc)
• Subtract cost of earnings (inputs, interest, maintenance costs, etc)
Further Discussion of Haig-Simon definition
• Problem with measurement.
– Timing problems. Lotteries and annuities.
Retained corporate earnings.
– Uncertainty Problems. E.g. Intellectual property.
• Why we care
– Taxing only some forms of income lead to
distortions and fairness issues.
Federal Tax Definition of Income
• Tax code “lays out transactions and events
that trigger tax liability”
• Adjusted Gross Income (AGI)
– Wages and Salaries (73%)
– Returns to Capital (dividends, interest, cap gains,
rent, royalties)
– Small Business Income (mixture of the two)
Capital Issues
• MOST Interest and Dividend Income is exempt (pension plans, tax-free
bonds, etc), though some dividend income excluded from AGI may have
taxed by corporate income tax.
• Only Realized Nominal Gains/Losses counted
• Exemptions
– Gains held until death
– Gains on owner-occupied housing up to $500K
• Cap gains are taxed at special rates (15%)
• In general cap gains can be taxed once, twice (because of interaction with
Corporate Tax) or not at all!
– The amount of cap gain included in AGI over 1980 – 2004 is roughly equal to
Haig-Simon definition, but that just reflects rough balance of huge “errors” in
both directions.
• Interpretation: Because of generally lower rates on returns to savings (via
exemptions from 401ks, IRAs, and special cap gains rate), our system is
really a hybrid of an income tax and a consumption tax.
Other Exclusions from Taxable Income
• $1 trillion (2004) excluded from AGI due to
evasion.
• $363B (2004) State and Local Tax Deduction
• $340B (2004) Mortgage/Home Equity Loan
Interest Deduction.
• $166 (2004) Charitable Contributions
• $62 (2004) Medical Dental Deductions
• Standard Deduction
• Personal Exemptions
