Development Economics — Lesson
Development Economics: Understanding Growth Beyond Numbers
Hook: The Tale of Two Villages
Imagine two Indian villages, Village A and Village B. Both have similar incomes per person, but Village A has clean drinking water, good schools, and low infant mortality rates, while Village B struggles with poor health and illiteracy despite similar income levels. Which village is truly more developed? This story shows us that development is more than just income; it includes health, education, and quality of life.
Core Concepts
What is Development Economics?
Development Economics studies how countries improve the economic, social, and institutional conditions of their people. It focuses on policies and strategies to promote economic growth, reduce poverty, and enhance human welfare.
Key Indicators of Development:
| Indicator | Description | Indian Example |
|---|---|---|
| Per Capita Income | Average income per person | India’s per capita income rose to ₹1.97 lakh (FY2023) |
| Human Development Index (HDI) | Composite index of life expectancy, education, and income | India’s HDI is 0.645 (2021), ranked 132nd globally |
| Poverty Rate | Percentage of population below poverty line | India reduced poverty from 45% (1993) to ~22% (2011) |
| Infant Mortality Rate (IMR) | Deaths of infants per 1000 live births | IMR declined to 28 (2021) from 58 (2000) |
Economic Growth vs Economic Development:
- Economic Growth: Increase in real GDP or per capita income.
- Economic Development: Improvement in living standards, education, health, and reduction of poverty and inequality.
Stages of Economic Development (Rostow’s Model):
- Traditional Society
- Preconditions for Take-off
- Take-off
- Drive to Maturity
- Age of High Mass Consumption
Role of Agriculture and Industry in Development:
In India, agriculture employs nearly 42% of the workforce but contributes only about 17-18% to GDP, indicating low productivity. Industrial and service sectors drive growth but development must be inclusive.
Key Formulas & Rules
1. Per Capita Income (PCI):
2. Human Development Index (HDI):
HDI is a geometric mean of three indices:
- Life Expectancy Index (LEI)
- Education Index (EI)
- Income Index (II)
3. Poverty Ratio (Headcount Index):
4. Growth Rate of Real GDP:
Did You Know?
India’s Kerala is often cited as a development success story because it has a low per capita income compared to some states but boasts the highest literacy rate (~96%), lowest infant mortality rate, and highest life expectancy in India. This shows that social development can outpace economic growth!
Exam Tips
