Meaning and Definitions of Economics: Wealth, Welfare, Scarcity & Growth

1. Introduction: What is Economics in Everyday Life?

Imagine you are a college student in Indore and your parents give you ₹3,000 as monthly pocket money. With this ₹3,000, you want to:

1. Buy textbooks and photocopies (₹1,000)
2. Refill petrol in your scooter (₹1,200)
3. Eat out at Chappan Dukan with friends (₹1,000)
4. Buy a new pair of sneakers (₹1,500)

Your total desires cost ₹4,700, but you only have ₹3,000! So what do you do? You prioritize — you buy the books and petrol first, spend less on snacks, and postpone the sneakers to next month.

Congratulations — you just practiced Economics!

Origin of the Word “Economics”

• The English word “Economics” comes from two ancient Greek words:
  • Oikos = A House / Household
  • Nemein (or Nomos) = To Manage / Management
• Together, Oikonomia literally meant “Household Management” — managing a family’s limited income to meet the family’s needs.
• In ancient India, the Sanskrit equivalent was Varta (livelihood/economy) and Arthashastra (the science of material well-being and statecraft).

2. The Four Major Definitions of Economics

As society evolved over the last 250 years, economists defined Economics in four major ways. In your DAVV exam, you must write all four stages in chronological order:

1. Wealth Definition (Classical View) — Adam Smith (1776)

• Propounded by: Adam Smith (known as the Father of Modern Economics) in his famous book “An Inquiry into the Nature and Causes of the Wealth of Nations” (1776). Supported by J.B. Say and J.S. Mill.
• Definition:

  “Economics is an inquiry into the nature and causes of the wealth of nations.” — Adam Smith “Economics is the science which treats of wealth.” — J.B. Say

• Key Features of Wealth Definition:
  1. Study of Wealth Only: Economics studies how wealth (material goods like gold, factories, crops, machines) is produced, distributed, and consumed.
  2. Concept of “Economic Man”: Assumes humans are driven purely by self-interest to earn and accumulate wealth.
  3. Only Tangible (Material) Goods: Included only physical goods (wheat, cloth, gold) and ignored non-material services (like teachers, doctors, lawyers).
• Criticism (Why it was opposed):
  • Social thinkers like Carlyle and Ruskin criticized it as a “Gospel of Mammon” (worship of money) and a “Dismal Science” because it gave too much importance to wealth and ignored human welfare and happiness.

2. Welfare Definition (Neo-Classical View) — Alfred Marshall (1890)

• Propounded by: Dr. Alfred Marshall in his famous book “Principles of Economics” (1890). Supported by A.C. Pigou and Edwin Cannan.
• Main Shift: Marshall shifted the focus of Economics from “Wealth” to “Human Being (Mankind)” — saying that wealth is only a means (tool) to achieve the end (human welfare).
• Definition:

  “Political Economy or Economics is a study of mankind in the ordinary business of life; it examines that part of individual and social action which is most closely connected with the attainment and with the use of the material requisites of wellbeing.” — Alfred Marshall

• Key Features of Welfare Definition:
  1. Primary Focus on Man, Secondary on Wealth: Economics studies ordinary people earning and spending money to live a better life.
  2. Social Science: Studies people living in society, not isolated individuals living in a forest.
  3. Study of Material Welfare: Focuses on material goods (food, housing, clothing) that promote human well-being.
• Criticism (by Lionel Robbins):
  • Ignores Immaterial Services: Why exclude the services of a doctor, teacher, or singer who also satisfy human wants?
  • “Welfare” is Subjective & Unmeasurable: Welfare is a mental feeling that cannot be measured accurately with a yardstick. Also, goods like cigarettes and alcohol generate wealth/GDP but harm human welfare!

3. Scarcity Definition (Analytical / Modern View) — Lionel Robbins (1932)

• Propounded by: Lord Lionel Robbins in his book “An Essay on the Nature and Significance of Economic Science” (1932).
• Definition:

  “Economics is the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses.” — Lionel Robbins

• Four Fundamental Pillars of Robbins’ Definition:
  1. Unlimited Wants (“Ends”): Human desires are endless. When you buy a bicycle, you want a scooter; when you buy a scooter, you want a car.
  2. Wants Differ in Urgency: Not all wants are equally urgent. Medicine for a sick child is more urgent than watching a movie, so we can rank our wants.
  3. Limited / Scarce Resources (“Means”): The resources (money, time, land, raw materials) available to satisfy wants are limited in supply compared to demand.
  4. Resources Have Alternative Uses: A ₹1,000 note can be used to buy books, pay an electricity bill, or buy clothes. A plot of land can grow wheat, build a factory, or become a playground.
• Criticism:
  • Robbins made Economics too static and dry (“neutral between ends”) and ignored macroeconomic issues like economic growth, unemployment, and national income.

4. Growth-Oriented Definition (Modern Dynamic View) — Paul A. Samuelson (1948)

• Propounded by: Nobel Laureate Prof. Paul A. Samuelson.
• Main Shift: Robbins only talked about allocating existing scarce resources today. Samuelson added the time element (future growth) — how a nation can increase and expand its resources over time through technology, education, and investment!
• Definition:

  “Economics is the study of how men and society choose, with or without the use of money, to employ scarce productive resources which could have alternative uses, to produce various commodities over time and distribute them for consumption now and in the future among various people and groups of society.” — Paul A. Samuelson

• Why Samuelson’s Definition is Considered the Best:
  1. Includes Robbins’ Scarcity and Choice.
  2. Includes Marshall’s Social Welfare and Distribution.
  3. Dynamic in nature — covers Economic Growth, Development, and Future Generations (“over time”).
  4. Applies to both barter economies (“without money”) and modern monetary economies (“with money”).

3. Classroom Activity 2: Write-Up & Comparison Table of Definitions

(As prescribed in the DAVV BBA Syllabus — Unit 1, Activity 2: “Students will prepare and submit a write-up on various definitions of economics.”)

Here is a ready-to-use comparative write-up table that summarizes all four definitions for your assignment and semester exam:

💡 DAVV Exam Tip

Question (10 Marks): “Define Economics. Critically examine the Wealth, Welfare, Scarcity, and Growth definitions of Economics.”

• Start with the Greek root Oikonomia (Oikos + Nemein = Household Management).
• Write the exact quoted definition, book name, and year for all 4 economists (Adam Smith 1776, Alfred Marshall 1890, Lionel Robbins 1932, Paul Samuelson 1948).
• Draw the 6-row Comparison Table at the end to score 9+/10!
