If we deduct depreciation from GNP, the measure of aggregate income that we obtain is called:
NNPmp
Understanding Aggregate Income Measures: GNP and Depreciation
When we study the economy, we look at different measures of how much income is being generated or how much production is happening. Two important measures are Gross National Product (GNP) and Net National Product (NNP). These measures help us understand the total economic activity within a country.
What is GNP?
Gross National Product (GNP) is the total value of all finished goods and services produced by a country's residents, regardless of where they are located. It includes income earned by citizens and businesses abroad but excludes income earned by foreigners within the country.
What is Depreciation?
Depreciation, also known as Consumption of Fixed Capital, represents the wearing out of capital goods like machinery, buildings, and equipment over time due to normal use. It's the cost associated with replacing these assets as they become old or obsolete.
Relating Gross and Net Measures
Economic measures are often presented as either "Gross" or "Net". The difference between a Gross measure and its corresponding Net measure is typically depreciation.
- Gross measures include the value of capital used up in production (depreciation).
- Net measures subtract the value of capital used up in production (depreciation).
The relationship can be expressed with a simple formula:
\( \text{Net Measure} = \text{Gross Measure} - \text{Depreciation} \)
Calculating NNP from GNP
Applying this concept to GNP and NNP:
Net National Product (NNP) is obtained by subtracting depreciation from Gross National Product (GNP).
Mathematically, this is represented as:
\( \text{NNP} = \text{GNP} - \text{Depreciation} \)
The question asks for the measure of aggregate income obtained when depreciation is deducted from GNP. Following the formula, this results in NNP.
Considering Market Price
Economic aggregates can be measured at market price (mp) or factor cost (fc). Market price includes indirect taxes minus subsidies, while factor cost represents the cost of factors of production. If GNP is given at market price (GNPmp), subtracting depreciation will give NNP also at market price (NNPmp), assuming no other adjustments like net indirect taxes are made at this step.
So, \( \text{GNP}_{\text{mp}} - \text{Depreciation} = \text{NNP}_{\text{mp}} \)
Analyzing the Options
Let's look at the given options in light of our understanding:
- \( \text{GDP}_{\text{mp}} \): Gross Domestic Product at market price. GDP measures production within the geographical boundaries of a country, regardless of who produces it. Subtracting depreciation from GNP doesn't give GDP.
- \( \text{NNP}_{\text{mp}} \): Net National Product at market price. This is derived by subtracting depreciation from GNP at market price, which aligns with our calculation.
- \( \text{NDP}_{\text{mp}} \): Net Domestic Product at market price. This is derived by subtracting depreciation from GDP at market price. Subtracting depreciation from GNP gives NNP, not NDP.
- \( \text{NDP}_{\text{fc}} \): Net Domestic Product at factor cost. This is derived by subtracting depreciation from GDP at factor cost, or from NDPmp by subtracting net indirect taxes. Subtracting depreciation from GNP gives NNP, not NDP.
Therefore, deducting depreciation from GNP results in NNP.
| Measure | Relationship |
|---|---|
| GNP (Gross National Product) | Total production by nationals (residents), before accounting for capital depreciation. |
| NNP (Net National Product) | GNP minus Depreciation. Represents production by nationals after accounting for capital used up. |
| GDP (Gross Domestic Product) | Total production within geographical boundaries, before accounting for capital depreciation. |
| NDP (Net Domestic Product) | GDP minus Depreciation. Represents production within geographical boundaries after accounting for capital used up. |
Conclusion
The process of deducting depreciation from a gross measure like GNP converts it into a net measure. Specifically, GNP less depreciation equals NNP. The market price (mp) designation remains consistent in this subtraction unless otherwise specified.
Revision Table: GNP, NNP, and Depreciation
| Concept | Formula | Explanation |
|---|---|---|
| Gross to Net | \( \text{Net} = \text{Gross} - \text{Depreciation} \) | Depreciation is the difference between Gross and Net measures for the same aggregate (National or Domestic). |
| GNP to NNP | \( \text{NNP} = \text{GNP} - \text{Depreciation} \) | Subtracting depreciation from Gross National Product gives Net National Product. |
| GNPmp to NNPmp | \( \text{NNP}_{\text{mp}} = \text{GNP}_{\text{mp}} - \text{Depreciation} \) | If GNP is at market price, NNP obtained after deducting depreciation is also at market price. |
Additional Information: National Income Accounting Concepts
Understanding aggregate income involves several key concepts:
- Market Price vs. Factor Cost:
- Market Price (mp): The price consumers pay, including net indirect taxes (Indirect Taxes - Subsidies).
- Factor Cost (fc): The cost of the factors of production (land, labor, capital, entrepreneurship), excluding net indirect taxes.
- Relation: \( \text{Aggregate}_{\text{mp}} = \text{Aggregate}_{\text{fc}} + \text{Net Indirect Taxes} \)
- Or: \( \text{Aggregate}_{\text{fc}} = \text{Aggregate}_{\text{mp}} - \text{Net Indirect Taxes} \)
- Domestic vs. National:
- Domestic: Refers to economic activity within the geographical boundaries of a country (e.g., GDP, NDP).
- National: Refers to economic activity by the residents (nationals) of a country, regardless of location (e.g., GNP, NNP).
- The difference is Net Factor Income from Abroad (NFIA). NFIA is income earned by residents from abroad minus income earned by foreigners within the country.
- Relation: \( \text{National Aggregate} = \text{Domestic Aggregate} + \text{NFIA} \)
- Or: \( \text{Domestic Aggregate} = \text{National Aggregate} - \text{NFIA} \)
These distinctions (Gross/Net, Market Price/Factor Cost, Domestic/National) help in calculating various important macroeconomic indicators like GDP, GNP, NNP, NDP, and National Income.
