Chapter 8: Building Blocks in Economics —
The Problem of Choice

1️⃣ Needs vs Wants

• Needs = essentials like food, water, shelter.
• Wants = gadgets, vacations, luxury items — unlimited & keep changing (e.g. bicycle → motorbike → car).

Fig 8.1 — Needs vs Wants:

2️⃣ Choices & Limited Resources

• Resources = factors used to produce goods/services — natural (water, coal) or human-made (capital, technology).
• Resources are limited/scarce but have alternative uses — households AND economies must choose how to use them best.

3️⃣ Opportunity Cost

Example: A farmer has limited land, water & labour — must choose between growing barley & wheat.

Growing more barley means giving up some wheat — that sacrificed wheat is the opportunity cost of growing more barley.

4️⃣ Production Possibility Curve (PPC)

• Plotting the barley/wheat table gives a downward sloping curve — moving along it shows the trade-off.
• Every point on the PPC = maximum output possible through efficient, waste-free use of resources.
• Helps enterprises & governments in better planning & decision-making.

5️⃣ What does Economics Deal With?

• Economics comes from Greek oikonomia = oikos (household) + nemein (management) → "household management."
• Deals with how choices are made by optimising the use of limited resources to satisfy needs & wants.
• Explains how economic entities — consumers, producers, governments, financial institutions — interact: wages, wealth distribution, prices, investment, government policy effects.
• Good decisions rely on data & analysis (economic surveys, company financial statements) — not guesswork.

6️⃣ Scope of Work of Economists

7️⃣ Economic Survey of India

• Prepared by the Ministry of Finance; presented in Parliament before the Union Budget.
• Reviews the past year's economic performance — agriculture, industry, services, employment, inflation, education, health, infrastructure.
• Acts as a blueprint for the upcoming Union Budget & helps citizens understand economic data.

8️⃣ Key Questions in Economics

Mismatch between unlimited wants & limited resources → Scarcity → Choices → 3 key questions:

9️⃣ What & For Whom to Produce

What to Produce: Which goods/services, and how much, to meet economy's needs. E.g. sugarcane/paddy (water-intensive, high profit) vs millets/pulses (water-saving, sustainable) — reflects trade-off between short-term gains & long-term sustainability.

For Whom to Produce: Depends on income levels, tastes & needs of different consumer groups.

Producers study consumer preferences, income & demand before deciding what to make — ensures resources aren't wasted.

🔟 How to Produce?

• Producers choose the right mix of land, labour, capital & technology.
• Labour-intensive — more workers, less machinery (e.g. agriculture, handicrafts).
• Capital-intensive — more machines/technology, fewer workers (e.g. steel, automobiles).
• Choice depends on: cost of capital, technology level, nature of product (customised → skilled labour; mass-produced → machines), cost/availability of labour, and govt. laws/regulations.

1️⃣1️⃣ Factors of Production

1️⃣2️⃣ Economic Systems

Three kinds: Planned, Market & Mixed economies — each answers the 3 key questions differently.

1️⃣3️⃣ Planned Economy

• A central planning authority (govt.) makes all major decisions — what, how much, how & at what price.
• Govt. owns most resources — land, factories, banks, transport.
• Enterprises follow the authority's targets, heavily regulated via permits/licenses.
• Limits competition → little motivation to innovate or improve quality.
• Examples: former Soviet Union, North Korea, Cuba.

1️⃣4️⃣ Market Economy

• What/how/how much to produce decided by demand & supply — little govt. intervention.
• Govt. acts like a referee — ensures safety & law/order, doesn't control prices/production.
• Ownership of factories, shops & land rests mainly with individuals & private companies.
• Competition among producers → better quality, lower prices, innovation.
• Examples: USA, Japan, Hong Kong.

1️⃣5️⃣ Mixed Economy

• Combines features of both market & planned economies.
• Private individuals, enterprises AND government all play a role — plus large public sector companies.
• Government: fair competition rules, consumer protection, transparency, public goods, welfare programmes.
• Market: profit-making businesses, innovation, competition.
• Examples: India (post-1991), China (post-1978), Germany, Sweden. Even the USA & Singapore have significant govt. involvement.

1️⃣6️⃣ India's Economic Journey

• Post-Independence: India followed a state-led, planned-economy-like approach — govt. controlled industries via licenses/permits; banking, transport & heavy industries dominated by the public sector.
• By 1991: serious economic difficulties → major economic reforms — reduced regulations, encouraged private enterprise, opened economy to global trade & investment, increased competition.
• Result: India gradually shifted towards a more market-oriented, mixed economy while retaining an important government role.
