The difference between gross national product and net national product equals to:

Question

Accepted Answer

The correct option is 2: Depreciation

The difference between any 'Gross' measure of national income, such as Gross National Product (GNP), and its corresponding 'Net' measure, such as Net National Product (NNP), is always the value of **Depreciation**. In national income accounting, depreciation is formally known as 'Consumption of Fixed Capital.' This amount represents the estimated value of the wear and tear, and obsolescence of the economy's fixed assets—machinery, equipment, and buildings—that occurs during the production of goods and services. The 'Gross' figure includes this capital consumption, reflecting total output before accounting for the need to replace used capital. By subtracting the Depreciation (or replacement cost) from the Gross National Product, we arrive at the Net National Product, which is a more accurate figure for the income available to the nation for consumption or net investment without eroding its production base.

The incorrect option is 1: Indirect taxes
Indirect taxes are used to adjust national income from a market price valuation to a factor cost valuation, not to convert a 'Gross' measure to a 'Net' measure. Specifically, the calculation involves **Net Indirect Taxes**, which are the total Indirect Taxes collected by the government minus any Subsidies provided. This figure is subtracted from the Market Price measure to get the Factor Cost measure (e.g., GNP at Market Price minus Net Indirect Taxes equals GNP at Factor Cost). This is a purely price-level adjustment.

The incorrect option is 3: Consumer expenditure
Consumer expenditure is a significant **component** of the national product when using the expenditure method of calculation. It is the total spending by households on final goods and services. In the equation for GNP, consumption is one of the four main aggregates that are added together (Consumption + Investment + Government Spending + Net Exports). Therefore, it is a part of the whole, rather than the residual difference used for converting a Gross figure to a Net figure.

The incorrect option is 4: Net exports
Net exports, calculated as total exports minus total imports, are another key **component** used in the expenditure method for calculating GNP. This component ensures that the value of the final goods and services produced domestically but sold abroad (exports) is included, while the value of foreign-produced goods and services consumed domestically (imports) is excluded. It represents the economy's trade balance with the rest of the world. Like consumer expenditure, net exports are an aggregate used to calculate the national product, not the adjustment factor between its Gross and Net forms.
