B. Measuring GDP: The Expenditure Aproach
- Four components of aggregate expenditure [Table 1]
a. Consumption (C)
- Spending on consumption goods and services
- Examples: Mineral water, "Full Monty"
b. Investment (I)
- Spending on capital goods
- Examples: Computers, 18-wheelers, houses
c. Government spending (G)
- Spending by the govt. on goods and services
- Examples: Toilet seats, submarines
- Note: G Does not include transfer payments (WHY?)
d. Net exports (X-IM)
- Net demand by foreigners for our goods and services
- Exports (X): Wheat, "Baywatch"
- Imports (IM): Cars, VCRs
- GDP = Aggregate expenditure
C. Measuring GDP: The Factor Incomes Approach
- Begin with National income [Table 2]
- Compensation of employees
- Net interest
- Rental income
- Corporate profits
- Proprietors' income
- Obtain Net National Product [Table 3]
- NNP = NI + Indirect taxes - Subsidies
- Obtain Gross National Product
- Obtain Gross Domestic Product
- GDP = GNP - Net factor income from abroad
D. Incomes
- National Income
- NI = Wages + Interest + Profits + Rent + Proprietors' income
- Personal income
- Personal income is the income received by, or on behalf of, all persons from all sources: from participation as laborers in production, from owning a home or business, from the ownership of financial assets, and from government and business in the form of transfers. It includes income from domestic sources as well as the rest of world. It does not include realized or unrealized capital gains or losses.
- PI = NI - (Corporate profits taxes + Payroll taxes etc.) + Transfer payments
- Disposable personal income
- Disposable personal income is the income available to persons for spending or saving. It is equal to personal income less personal current taxes.
- DI = Personal income - Personal taxes
Personal consumption expenditures (PCE) is the value of the goods and services purchased by, or on the behalf of, “persons” who reside in the United States.
Personal outlays is the sum of PCE, personal interest payments, and personal current transfer payments.
Personal saving is personal income less personal outlays and personal current taxes.
The personal saving rate is personal saving as a percentage of disposable personal income.
E. Saving
- Household saving
- Government saving
- T - G
- Budget surplus/deficit
- National saving
- Borrowing from abroad
- IM - X
- Trade deficit/surplus
F. The Saving-Investment Relationship
- S = I + (G - T) + (X - IM)
