Economic Growth — Overview
Learning Objectives
By the end of this section, you should be able to:
- Identify the key determinants that drive long-run economic growth in any economy
- Distinguish between economic growth (quantitative) and economic development (qualitative)
- Evaluate multiple measurement tools — GDP, GNP, Per Capita Income, HDI — and explain when each is most useful
- Analyse real-world case studies from India, the US, Singapore, Norway, and South Korea to connect theory with evidence
- Explain how institutional quality, technology, human capital, and trade interact to produce sustained growth
- Assess the limitations of GDP as a sole indicator of societal well-being
Quick Answer
Economic growth is the sustained increase in an economy's output of goods and services over time, usually expressed as the annual percentage change in real GDP. Growth is driven by several interconnected forces: investment in education and health (human capital), technological progress, strong institutions, access to natural resources, and openness to trade and foreign investment. However, growth alone does not guarantee development — a country can expand its GDP while leaving large sections of its population in poverty. That is why economists also use measures like the Human Development Index (HDI) and Sustainable Development Goals (SDGs) to capture the broader picture of societal progress.
