Solutions
The correct answer is NNP at market price = GNP at cost price - Cost of depreciation of stock of capital.
Key Points
The true statement is:
NNP at market price = GNP at cost price - Cost of depreciation of stock of capital
Here's a breakdown of the terms and why this relationship holds:
NNP (Net National Product) at market price:
- It measures the total value of all final goods and services produced by a nation's residents in a given period, adjusted for the cost of depreciation.
- It reflects the actual market value of the output, including taxes and subsidies.
GNP (Gross National Product) at cost price:
- It measures the total value of all final goods and services produced by a nation's residents in a given period, but it does not account for depreciation.
- It reflects the factor cost of production, excluding taxes and subsidies.
Cost of depreciation of stock of capital:
- It accounts for the wear and tear of capital goods (machines, buildings, etc.) used in production.
- It's a necessary deduction to arrive at a more accurate measure of net output, as capital goods lose value over time.
Additional Information
Relationship between NNP and GNP:
NNP is always lower than GNP because it subtracts depreciation from GNP.
This subtraction is essential because it recognizes that a portion of GNP is used to replace worn-out capital rather than generating new output.
Explanation of the formula:
NNP at market price starts with GNP at cost price, which captures the total value of production.
To arrive at the net value of production, the cost of depreciation is subtracted, reflecting the portion of output used to maintain existing capital.
The other options are incorrect because:
Adding depreciation to GNP would overestimate NNP.
