Scarcity, Choice & Resource Allocation
Unit 1 of Economics: Explores why resources are limited, how choices shape economic decisions, and how societies allocate scarce resources efficiently—with real-world examples from Nepal’s economy and daily life.
TAKEAWAYS:
- Scarcity forces trade-offs because unlimited wants clash with limited resources.
- Opportunity cost is the true cost of any choice (e.g., studying vs. working).
- Production Possibility Curve (PPC) visually shows trade-offs and efficiency.
- Allocation methods (market, command, tradition) determine how resources are used.
- Nepal’s remittance economy and loan interest reflect scarcity and choice daily.
- Understanding these concepts helps explain why prices rise or fall in markets.
1. The Problem of Scarcity
Economics begins with a simple but profound truth: resources are limited, but human wants are unlimited. This gap creates scarcity, the core issue economics addresses.
Why Scarcity Exists
- Limited Resources: Land, labor, capital, and entrepreneurship (LLCE) are finite.
- Unlimited Wants: People desire more goods (e.g., smartphones, education) than can be produced with available resources.
- Trade-offs: Choosing one thing means giving up another (e.g., saving for a car vs. traveling).
Example: Nepal’s Remittance Economy
Nepal relies heavily on remittances (money sent home by workers abroad). In 2023, remittances accounted for 28% of Nepal’s GDP (Nepal Rastra Bank). This shows:
- Scarcity of domestic jobs: Many Nepalis work abroad because local opportunities are limited.
- Choice: Families allocate remittance money between education, housing, or consumption.
- Opportunity cost: Spending on a house means less money for children’s education.

2. The Concept of Choice
Scarcity forces individuals, firms, and governments to make choices. Every decision involves:
- What to produce? (e.g., Nepal’s focus on hydropower vs. agriculture).
- How to produce it? (e.g., manual labor vs. machinery).
- For whom to produce? (e.g., who gets loans from banks?).
Opportunity Cost: The True Cost
Opportunity cost is what you give up to get something else. Worked Example: Studying vs. Working
- Scenario: A student in Pokhara can either:
- Work part-time (₹10,000/month) or
- Study full-time (forces them to borrow ₹5,000/month).
- Opportunity cost of studying:
- Lost wages: ₹10,000/month.
- Interest on loan: ₹500/month.
- Total: ₹10,500/month.

"Lost Wages: ₹10,000" : 76.9
"Loan Interest: ₹500" : 3.8
"Time Cost (Sleep/Health)" : 19.3
3. Resource Allocation
Societies allocate scarce resources using different methods:
| Method | How It Works | Example in Nepal |
|---|---|---|
| Market | Prices guide allocation (supply/demand). | Daraz uses algorithms to allocate stock. |
| Command | Government decides allocation. | NEPSE regulates stock market trading. |
| Tradition | Customs dictate allocation. | Caste-based land inheritance. |
| Mixed | Combination of methods. | Nepal’s economy (market + government). |
Market Allocation: Daraz’s Inventory
Daraz uses supply and demand to allocate products:
- High demand (e.g., smartphones) → Higher prices → More suppliers.
- Low demand (e.g., winter coats in summer) → Lower prices → Fewer suppliers.

4. Production Possibility Curve (PPC)
The PPC shows maximum possible output given scarce resources. It illustrates:
- Efficiency: Points on the curve (e.g., A).
- Inefficiency: Points inside the curve (e.g., B).
- Unattainable: Points outside the curve (e.g., C).
Worked Example: Nepal’s Hydropower vs. Agriculture
Assume Nepal can produce:
- 100 units of hydropower or 200 units of rice with current resources.
- PPC Equation:
- (where = hydropower, = rice).
- Scenario: If Nepal produces 50 units of hydropower, how much rice?
- → .

Caption: Nepal’s PPC: Moving from point A (all hydropower) to C (all rice) requires trade-offs.
5. Economic Systems and Allocation
Different economic systems allocate resources differently:
| System | Key Feature | Nepal’s Example |
|---|---|---|
| Capitalist | Private ownership, market-driven. | Daraz, Pathao (ride-hailing apps). |
| Socialist | Government ownership, equality focus. | NEPSE (regulated stock market). |
| Mixed | Combination of both. | Nepal’s economy (private + public). |
Nepal’s Mixed Economy
- Private sector: Daraz, Khalti (digital payments).
- Public sector: NTC (telecom), Nepal Rastra Bank (monetary policy).

6. Real-World Applications
In the Real World
eSewa’s Dynamic Pricing
- Idea: Elasticity of demand (Unit 5).
- How: eSewa adjusts transaction fees based on demand (e.g., higher fees during festivals).
- Why: When more people use eSewa (high demand), fees rise to balance supply.
Ncell’s 4G Rollout
- Idea: Opportunity cost (Section 2).
- How: Ncell chose to invest in 4G instead of expanding rural coverage, giving up slower but broader access.
- Why: Higher profits from urban users justified the trade-off.
NEPSE’s Stock Market Crashes
- Idea: Scarcity of liquidity (Section 1).
- How: During crashes, few buyers/sellers → scarce trading opportunities → volatile prices.
- Why: NEPSE must regulate to ensure fair allocation of stocks.

"2023" : 3500
Caption: Scarcity of liquidity during crashes (e.g., 2022 dip) forces NEPSE to intervene.
Exam Tip
- Scarcity: Always link to real Nepalese examples (remittances, hydropower, NEPSE).
- Opportunity Cost: Use numerical examples (e.g., studying vs. working).
- PPC: Draw a labeled graph with numbers (e.g., hydropower vs. rice).
- Allocation Methods: Compare market vs. command using Nepal’s economy.
- Key Terms: Define scarcity, choice, opportunity cost, PPC clearly.
- Common Mistake: Don’t confuse scarcity (limited resources) with shortage (temporary lack).
Practice Question: "Explain how Nepal’s reliance on remittances reflects the concepts of scarcity and choice. Use a PPC to illustrate the trade-offs faced by a Nepali family receiving remittances."
