    Study Notes

    Chapter 5: National Income and Standard of Living

    • Macroeconomics is the study of the economy as a whole, focusing on the general price level, national output, and national employment
    • Microeconomics focuses on individual market interactions and price mechanisms for resource allocation
    • Economic agents (households, firms, and governments) react to economic changes via robust analyses of their constraints, benefits, and consequences
    • Macroeconomic objectives include improving living standards, economic stability, and sustainable and inclusive growth
    • Macroeconomic policies (demand-side and supply-side) are used to achieve these objectives
    • National income is a measure of the overall level of economic activity in a country
    • GDP (Gross Domestic Product) measures the total monetary value of all final goods and services produced within a country's borders
    • GNI (Gross National Income) adds factor incomes earned by residents from overseas sources and subtracts factor incomes earned by non-residents from the domestic economy
    • Nominal income is measured at current prices, while real income accounts for inflation using a base year for comparison

    Measuring the Rate of Economic Growth

    • Economic growth is best measured by the percentage change in real GDP
    • Nominal GDP is unsuitable for growth measurement as it does not account for inflation.
    • Real GDP, measured in constant dollars, eliminates the effect of price changes

    Measuring the Material Standard of Living

    • Standard of living (SOL) encompasses material and non-material aspects, with the material aspect tied closely to the amount of goods and services available for consumption
    • National income is used as an indicator of the material aspect of SOL, with higher income implying higher purchasing power
    • Indicators beyond national income such as inflation rate, unemployment, and balance of trade reflect the material SOL

    Limitations of Using National Income

    • National income figures are commonly used but imperfect to measure standard of living
    • Inter-temporal comparisons (comparing over time) are limited by changes in prices, population size, and income distribution
    • International comparisons (comparing across countries) are limited by currency conversion rates, differences in goods and services, and income distribution

    Alternative Measures of Living Standards

    • HDI (Human Development Index) is a composite measure by the UN, considering material and non-material aspects like GNI, education, and health
    • MEW (Measure of Economic Welfare) adjusts GDP to include non-market activities, environment, and income distribution
    • SPI (Social Progress Index) is a framework for measuring social progress, including basic human needs, foundations of well-being, and opportunity

    Decision-Making Example (Bhutan)

    • Bhutan uses a Gross National Happiness index instead of GDP as a barometer of economic success
    • Indicators include social and environmental factors as well as income distribution.

    Appendix (Singapore context)

    • Singapore is using a combination of GDP and GNI to analyze economic performance
    • National income figures are commonly used to measure the overall level of economic activity in a country
