Answer: (B) capital-augmenting technological progress
This question tests a basic concept from economic growth theory.
Think of it practically: when a farmer replaces a wooden plough with a steel plough, what changes?
The TOOL (capital) becomes better and more productive, while the worker (labour) remains the same person doing the same job.
The steel plough can dig deeper, last longer, and work faster than the wooden one — meaning the same capital good is now more productive.
This is capital-augmenting technological progress.
(a) Labour-augmenting technological progress — this would mean making the WORKER more productive while using the same tools.
Examples:
- teaching a farmer new techniques
- improving their skills through training
- providing better education.
The focus is on improving human capability, not the tool itself.
(b) Capital-augmenting technological progress — CORRECT.
This means making the CAPITAL (tools, machines, equipment) more productive.
Replacing a wooden plough with a steel plough is upgrading the tool itself, increasing its productivity.
Other examples:
- replacing a handloom with a power loom
- a bullock cart with a tractor.
(c) Capital-reducing technological progress — this would mean achieving the same output with LESS capital.
For example, if a new software allowed a company to close a factory while maintaining the same production.
Replacing wood with steel is not reducing capital — it is improving it.
Answer: Capital-augmenting technological progress.
Simple way to remember:
Better tools/machines = capital-augmenting.
Better trained workers = labour-augmenting.
Capital-augmenting technological progress means making tools and machines more productive, while labour-augmenting means making workers more skilled or capable.
The steel plough example tests whether students can distinguish between improving the tool itself versus improving the worker's ability to use the tool.
Types of Technological Progress
Indian Economy labour-augmenting technological progress capital-augmenting technological progress capital-reducing technological progress
Types of Technological Progress: Capital vs Labour Augmenting
Capital-augmenting: Better tools/machines increase productivity of capital
Labour-augmenting: Better skills/training increase productivity of workers
Steel plough replacing wooden plough = capital-augmenting progress
Capital-reducing: Same output with less capital investment
Core Concept
Technological progress in economics refers to improvements that increase productivity. The key is identifying what becomes more productive — the worker, the tool, or the overall efficiency of capital use.
Classification by Impact
Type | What Improves | Focus | Example |
|---|---|---|---|
Labour-Augmenting | Worker productivity | Human skills/capability | Training farmers in new techniques |
Capital-Augmenting | Tool/machine productivity | Equipment upgrade | Steel plough replacing wooden plough |
Capital-Reducing | Overall efficiency | Less capital needed | Software reducing factory requirements |
Agricultural Examples
Tractors replacing bullocks — capital-augmenting (better machine)
HYV seeds replacing traditional varieties — capital-augmenting (better input)
Training on crop rotation techniques — labour-augmenting (better knowledge)
Drip irrigation reducing water usage — capital-reducing (same output, less input)
Question Context
The steel plough vs wooden plough example tests whether students can identify that upgrading the tool itself (not the farmer's skills) makes this capital-augmenting technological progress.
Trap: Confusing labour-augmenting with capital-augmenting — remember the tool gets better, not the worker
Trap: Thinking any technological change is labour-augmenting — focus on what specifically improves
Memory aid: Better tools = capital-augmenting, Better training = labour-augmenting
Agricultural Mechanization in India
Indian Economy steel wooden ploughs agricultural production
Agricultural Mechanization: From Traditional to Modern Implements
India's farm mechanization increased from 40% in 2001 to 60%+ by 2020
Small farmers still rely heavily on traditional wooden implements
Tractorization grew fastest — from 1.8 million to 7+ million tractors
Steel ploughs can increase productivity by 15-25% over wooden ones
Mechanization Trends
India's agricultural mechanization involves replacing traditional implements with modern machinery. This transition varies significantly across regions, with Punjab, Haryana leading and eastern states lagging behind.
Traditional vs Modern Implements
Function | Traditional Tool | Modern Alternative | Productivity Gain |
|---|---|---|---|
Ploughing | Wooden plough | Steel plough/Tractor | 15-25% faster |
Sowing | Manual broadcasting | Seed drill | 10-15% less seed waste |
Harvesting | Sickle/Scythe | Combine harvester | 80% time reduction |
Threshing | Cattle trampling | Threshing machine | 50% labour reduction |
Mechanization Drivers
# Agricultural Mechanization
## Government Support
- Subsidies on machinery
- Custom Hiring Centers
- RKVY scheme
## Economic Factors
- Rising labour costs
- Labour shortage
- Economies of scale
## Challenges
- Small farm size
- High machinery cost
- Lack of creditRegional Patterns
Punjab leads with 95%+ mechanization — Green Revolution legacy
Uttar Pradesh has highest absolute number of tractors but low per-hectare density
Eastern states like Bihar, West Bengal still rely heavily on traditional tools
Custom Hiring Centers help small farmers access modern machinery without ownership
