Chapter 7: Measuring Domestic Output and National Income

Vocabulary practice flashcards defining key national accounting metrics, income formulas, GDP adjustments, and visual tables from Chapter 7 study notes.

National Income Accounting

The system compiled by the Bureau of Economic Analysis (BEA) through the National Income and Product Accounts (NIPA) to assess economic health, track long-run growth, and guide economic policy.

Gross Domestic Product (GDP)

The dollar value of all final goods and services produced within a country's borders in a given period of time.

Intermediate Goods

Goods purchased for resale or for use as inputs in producing another product; they are excluded from GDP calculations to prevent double-counting.

Value Added

The market value of a firm's output minus the value of the input materials purchased from other firms at each stage of production.

Gross Output (GO)

An economic measure that sums total sales value at every stage of production, including all intermediate business-to-business transactions.

Multiple Counting

The distortion caused by erroneously including intermediate sales in GDP, which overstates total domestic output.

Public Transfer Payments

Direct government funds given to households (such as Social Security, welfare, or veterans' benefits) that generate no current output and are excluded from GDP.

Personal Consumption Expenditures (C)

Total household spending on durable goods, nondurable goods, and services, comprising approximately $68$ percent of U.S. GDP.

Gross Private Domestic Investment ($I_g$)

Total economic spending on capital stock, including business equipment and structures, residential construction, research and development, software/art creation, and changes in inventories.

Net Private Domestic Investment ($I_n$)

Gross investment minus depreciation (consumption of fixed capital), measuring the net change in a nation's total capital stock.

Net Exports ($X_n$)

Total exports minus total imports ($X_n = X - M$), representing net foreign demand for domestic output.

Expenditures Approach

The method of determining total GDP by adding all final spending across four sectors: $GDP = C + I_g + G + X_n$.

Income Approach

The method of determining GDP by summing all factor incomes earned in production: employee compensation, rents, interest, proprietors' income, corporate profits, and taxes on production/imports.

Net Domestic Product (NDP)

The total economic output available after allocating funds to replace consumed capital, calculated as $NDP = GDP - \text{consumption of fixed capital}$.

Accounting Step-down Table (GDP to DI)

A tabular display showing the step-by-step mathematical transition from total Gross Domestic Product ($29,185$ billion) down to Net Domestic Product, National Income, Personal Income, and Disposable Income ($21,626$ billion).

National Income (NI)

Total income earned by American-owned resources, calculated as $NI = NDP - \text{statistical discrepancy} + \text{net foreign factor income}$.

Personal Income (PI)

Total income received by households, computed by subtracting non-received earnings (corporate taxes, retained earnings, Social Security contributions) from National Income and adding transfer payments.

Disposable Income (DI)

Income remaining to households after personal taxes ($DI = PI - \text{personal taxes}$), which can be divided between personal spending ($C$) and saving ($S$).

Nominal GDP

Gross Domestic Product measured in current-year dollar prices, unadjusted for inflation or deflation.

Real GDP

Gross Domestic Product adjusted for price level changes using a price index to reflect constant base-year dollars.

GDP Price Index

A gauge of overall price changes calculated as $\text{Price Index} = \frac{\text{price of market basket in given year}}{\text{price of same basket in base year}} \times 100$.

Nominal and Real GDP Comparison Table

A dataset comparing physical unit output and price levels across multiple years to calculate price indices, unadjusted nominal GDP, and base-year adjusted real GDP.

Hedonic Adjustment

A statistical method employed by the BEA that treats goods as bundles of features to adjust prices for quality enhancements when computing real GDP.

Underground Economy

Unreported legal cash activity and illegal transactions that bypass official records, understating official GDP metrics.
