Economics Basics: Scarcity, Choice, Systems & Economic Methods

What is Economics?

Economics is the social science that studies how individuals, businesses, and governments allocate limited resources to satisfy unlimited wants. It answers two fundamental questions:

1. What to produce? (e.g., hotels vs. roads)
2. How to produce? (e.g., labor vs. technology)

The Core Problem: Scarcity

Scarcity exists because human wants are unlimited, but resources (land, labor, capital, entrepreneurship) are limited. This forces choices.

Opportunity Cost

The next best alternative forgone when a choice is made.

• Example: If Nepal invests ₹100 billion in tourism, it cannot spend it on healthcare. The opportunity cost is the healthcare benefits lost.

Economic Systems

Economic systems determine how resources are allocated. Three main types:

In the real world:

• Pathao uses a market system (supply-demand for rides) but relies on government regulations (e.g., driver licenses) → a mixed economy.
• NTC (Nepal Telecom) operates under a command-like structure (fixed prices in some areas) but competes with Ncell (market-driven).
• Nepal’s hospitality sector (e.g., Hotel Yak & Yeti) follows market principles (prices set by demand) but must comply with government tourism policies (e.g., foreign tourist quotas).

Methods of Economic Analysis

Economists use two main approaches:

1. Positive Economics

• Fact-based, descriptive ("What is?")
• Example: "Nepal’s GDP grew by 3.2% in 2023."
• Tools: Statistics, graphs, models.

2. Normative Economics

• Value-based, prescriptive ("What ought to be?")
• Example: "The government should reduce tourism taxes to boost revenue."
• Tools: Policy recommendations, ethical judgments.

Economic Models & Assumptions

Economists simplify reality using models (e.g., Circular Flow of Income, PPF). Key assumptions:

• Ceteris Paribus ("All else equal") – Only one variable changes at a time.
• Rationality – People make logical choices (e.g., booking a cheaper hotel room).

Worked Example: Nepal’s Tourism vs. Education Suppose Nepal has 100 units of resources. If it allocates:

• 60 units to tourism → 300,000 tourist arrivals
• 40 units to education → 50,000 new school seats

Opportunity Cost: For every 1 unit shifted to tourism, Nepal loses 1.5 school seats.

Microeconomics vs. Macroeconomics

Exam Tip

1. Define key terms precisely (e.g., "Scarcity is not poverty—it’s about limited resources vs. unlimited wants").
2. Use real-world examples (e.g., "Like Pathao’s surge pricing during Dashain").
3. Distinguish positive vs. normative – Examiners test this often!
4. Draw diagrams (PPF, circular flow) – Even if not asked, include them in answers.
5. Link to Nepal’s economy – Always relate theory to tourism, hospitality, or NEPSE (e.g., "Like Daraz’s market allocation system").

Final Checklist for Full Marks: ✅ Define scarcity, opportunity cost, and economic systems. ✅ Compare micro vs. macro with Nepal examples. ✅ Explain positive vs. normative with real cases (e.g., "The government should reduce VAT on hotel stays" = normative). ✅ Draw PPF and circular flow with labels. ✅ Apply ceteris paribus in a worked example (e.g., "If hotel prices rise, demand falls—assuming no change in tourist income").
