LESSON 2: THE NATIONAL INCOME

• Overview of national income and its significance in tracking economic growth.

Key Measures of National Income

• Gross National Income (GNI) and Gross Domestic Product (GDP) are primary measures used to analyze economic performance.

• Both figures help assess the total income or value produced by a country, offering insights into its economic health.

GROSS NATIONAL INCOME (GNI)

• Definition: Total income earned by a country's residents and businesses, worldwide, subtracting outflows to foreign countries.

  • Components Included:

    • Income from citizens regardless of residency (inside/outside).

    • Income earned by foreigners in the country is deducted.

• GNI Formula:

  • GNI = C (Consumption) + I (Investment) + G (Government Spending) + X (Net Exports) + NFIFA (Net Factor Income From Abroad)

EXAMPLE OF GNI

• GDP of Philippines: 400 billion USD

• Income by Filipinos Abroad: 30 billion USD

• Income by Foreigners in Philippines: 15 billion USD

• Resulting GNI: 400 + 30 - 15 = 415 billion USD

GROSS DOMESTIC PRODUCT (GDP)

• Definition: Total value of all goods and services produced within a country, regardless of who produces them.

• Distinction from GNI: GDP focuses on internal production only, including contributions from foreign workers within the country.

• GDP Formula:

  • GDP = C + I + G + (X − M)

  • Where X = Exports, M = Imports

• Net Exports (X-M) measures the difference between exports and imports.

EXAMPLE OF GDP

• Consumption (C): 250 billion USD

• Investment (I): 90 billion USD

• Government Spending (G): 60 billion USD

• Exports (X): 70 billion USD

• Imports (M): 50 billion USD

• Calculation:

  • GDP = 250 + 90 + 60 + (70 - 50)

  • GDP = 420 billion USD

TYPES OF GDP

• Nominal GDP:

  • Value of goods and services at current market prices; affected by inflation.

• Real GDP:

  • Value adjusted for inflation, using prices from a fixed base year to provide a clearer view of economic growth.

GDP Growth Rate

• Measures how quickly a country's economy is growing.

• Formula:

  • GDP Growth Rate = (Final GDP - Initial GDP) / Initial GDP * 100

IMPORTANCE OF GDP AND GNI

• GDP reflects the overall health of an economy, influencing investor confidence and decision-making regarding investments.

• Governments and policymakers utilize GDP and GNI to guide fiscal policies, including spending and taxation strategies.

INFLATION

• Definition: Rise in prices of goods and services, diminishing purchasing power.

• Impacts the real value of GDP and GNI, highlighting the necessity for tracking real (inflation-adjusted) figures.

WHY GDP AND GNI MATTER

• Both GNI and GDP are essential for evaluating a country's economic strength and guiding government and investor decisions about growth, spending, and policy implementation.

• Implications of GDP Growth:

  • Signals productivity and potential for job creation; enhances living standards.

• Consequences of Declining GDP:

  • Can indicate economic distress, high unemployment, or low productivity.
