Which of the following equation is appropriate for determining the Net Domestic Product (NDP)

Answer Details

Net Domestic Product (NDP) measures the total value of goods and services produced within a country's borders after accounting for the wear and tear on capital goods used in production.

The correct formula is:

\[\text{NDP} = \text{GDP} - \text{Depreciation}\]

GDP (Gross Domestic Product) measures total output within a country's borders without deducting for capital consumed in the production process. Depreciation (also called capital consumption allowance) represents the value of capital assets (machinery, equipment, buildings) that wore out or became obsolete during the production period.

Subtracting depreciation from GDP gives a more accurate picture of the economy's net productive capacity, since some of the gross output merely replaces worn-out capital rather than representing a genuine addition to wealth.

The other options are incorrect:

• GNP minus depreciation gives Net National Product (NNP), not NDP. GNP includes net income from abroad, which NDP excludes.
• GDP multiplied by net income from abroad is not a recognized economic formula.
• The option written as "NDP - GDP + Net Income from abroad" rearranges terms incorrectly and does not represent the standard NDP formula.
