1. Gross vs Net
Gross:
- Refers to the total value without deducting depreciation (wear and tear of capital goods).
- Includes the full value of goods and services produced in an economy.
- Key term: Depreciation (also called capital consumption).
Net:
- Refers to the value obtained after deducting depreciation from the gross value.
- Net value gives a more accurate picture of an economy’s productive capacity.
Formula:
Example:
If Gross Domestic Product (GDP) is ₹100 lakh and depreciation is ₹10 lakh:
2. Domestic vs National
Domestic:
- Refers to the value of goods and services produced within the geographical boundaries of a country, irrespective of who owns the resources (domestic or foreign entities).
- Example: A factory in India owned by a foreign company contributes to Domestic Product.
National:
- Refers to the value of goods and services produced by residents of a country, irrespective of their geographical location.
- Includes income earned abroad by Indian residents and excludes income earned in India by foreigners.
Formula:
Example:
If Domestic Income is ₹500 lakh and NFIA is ₹20 lakh:
3. Nominal vs Real
Nominal:
- Refers to the value of goods and services calculated at current market prices.
- Does not adjust for inflation, making it less reliable for comparisons over time.
Real:
- Refers to the value of goods and services calculated at constant prices (base year prices).
- Adjusts for inflation, giving a clearer picture of actual economic growth.
Formula:
Example:
If Nominal GDP is ₹1000 crore and CPI is 125:
4. Factor Cost vs Market Price
Factor Cost:
- Refers to the cost of production from the perspective of producers, excluding taxes but including subsidies.
- Represents the income earned by factors of production (land, labor, capital, and entrepreneurship).
Market Price:
- Refers to the price at which goods and services are sold in the market, including taxes and excluding subsidies.
Formula:
Example:
If Factor Cost is ₹500 crore, indirect taxes are ₹50 crore, and subsidies are ₹10 crore:
Key Takeaways:
- Gross vs Net: Gross includes depreciation, Net excludes it.
- Domestic vs National: Domestic focuses on geography, National focuses on ownership.
- Nominal vs Real: Nominal uses current prices, Real adjusts for inflation.
- Factor Cost vs Market Price: Market price accounts for taxes and subsidies; factor cost does not.
