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
