National Income

Learning Objective: Define and calculate national income using different methods

How do we measure whether Nepal's economy is growing or shrinking? The answer lies in national income -- the total value of all goods and services produced in the country. Nepal's GDP was approximately Rs. 5,100 billion (around USD 36 billion) in recent years. Understanding how this number is calculated helps us evaluate the nation's economic health.

Key Concepts

Gross Domestic Product (GDP)

GDP is the total market value of all final goods and services produced within a country's borders in a given year, regardless of who produces them.

• A Chinese-owned cement factory operating in Nepal contributes to Nepal's GDP.
• It includes both Nepali and foreign-owned production within Nepal.

Gross National Product (GNP)

GNP is the total market value of all final goods and services produced by the citizens/residents of a country, whether they are working domestically or abroad.

• Remittances sent by Nepali workers in Qatar, Malaysia, and the Gulf countries contribute to Nepal's GNP but not its GDP.
• GNP = GDP + Net Factor Income from Abroad

This distinction is particularly important for Nepal, where remittances account for about 25% of GDP, making GNP significantly higher than GDP.

Net National Product (NNP)

NNP = GNP - Depreciation

Depreciation (also called consumption of fixed capital) accounts for the wear and tear of machinery, buildings, and other capital goods.

Methods of Calculating National Income

1. Production (Output) Method

Add the value added by each sector of the economy:

• Agriculture: Rs. 1,700 billion (about 25% of Nepal's GDP)
• Industry: Rs. 700 billion
• Services: Rs. 2,700 billion (largest sector, including tourism, banking, telecom)

2. Income Method

Add all incomes earned by factors of production:

• Wages and salaries
• Rent from land
• Interest from capital
• Profits from businesses

3. Expenditure Method

Add all spending in the economy: GDP = C + I + G + (X - M)

• C = Consumer spending (household purchases of goods and services)
• I = Investment spending (business spending on capital goods)
• G = Government spending (public services, infrastructure)
• X - M = Net exports (exports minus imports)

Nepal typically has a trade deficit (imports exceed exports), making (X - M) negative.

Limitations of National Income Measures

• Does not account for unpaid work (household chores, subsistence farming common in rural Nepal)
• Ignores the informal economy (street vendors, unregistered businesses)
• Does not measure income inequality -- GDP may grow while most benefits go to a few
• Ignores environmental costs (pollution, deforestation)
• Does not reflect quality of life (health, education, happiness)

Key Term: GDP per capita is GDP divided by the total population. Nepal's GDP per capita is approximately Rs. 1,70,000 (about USD 1,300), classifying it as a low-income country.

Summary

• GDP measures production within a country's borders; GNP includes citizens' production abroad.
• Nepal's GNP is significantly larger than its GDP due to massive remittance inflows.
• National income can be calculated using the production, income, or expenditure method.
• GDP has limitations -- it misses informal work, inequality, and quality of life.
