Class 11th Economics: Introduction to Microeconomics and Statistics

Overview of Class 11th Economics Curriculum and $

• Economics: Deals with the study of Human Behaviour.

• Economic Observations in Daily Life: Everyday items such as Amul Gold Milk, Snickers Brownie bars, Rice, and even currency (Reserve Bank of India $100$ Rupee notes) represent economic transactions and the fulfillment of hunger and needs.

Definition of an Economy and Its Vital Processes

• What is an Economy?: "An economy is a system which provides people, the means to work and earn a living."

• Key Characteristics of the Economic System:

  • It consists of all institutions and organisations collectively.

  • These units enable people to earn an income.

  • Simultaneously, they help produce goods and services that people require for use.

  • Examples of Economic Units: Agriculture, Railways, and Transportation.

• Vital Processes of an Economy: To fulfill the objective of providing a living, every economy must undertake three essential economic activities:

  1. Production

  2. Consumption

  3. Investment (or Capital Formation)

The Fundamental Reason to Study Economics: Scarcity

• The Concept of Scarcity: Scarcity is the root of all economic problems. It refers to the limitation of supply in relation to demand for a commodity.

  • Example: Coal is scarce; while there is demand for its use in cars, machines, and airplanes, the supply is finite.

• Economizing of Resources: This refers to making the optimum use of available resources.

• Alternative Uses: Scarcity is not the only problem. Resources also have alternate (different) uses.

  • Example of Petrol: If an economy only has $100$ litres of petrol left, it must choose where to allocate it: Cars, Public Transport, or Airplanes.

  • Example of Machines: A specific machine cannot be used in a hotel and a factory simultaneously; a choice must be made.

• The Problem of Choice: Whenever a commodity is chosen for one use, other valuable uses must be rejected. This necessity of choosing is what creates an "Economic Problem."

The Economic Problem

• Definition: An economic problem is basically a problem of choice. Formally, it is defined as: "Economic Problem is a problem of choice involving satisfaction of unlimited wants out of limited resources having alternative uses."

• Reasons for the Existence of Economic Problems:

  1. Unlimited Human Wants: Human wants are never-ending and can never be fully satisfied. As soon as one want is met, a new one emerges. Furthermore, human wants differ in their level of priority.

  2. Scarcity of Resources: Resources like land, labour, and capital are limited in relation to their demand. Scarcity is universal, applying to all individuals, organisations, and countries. If resources were not scarce, no economic problem would exist.

  3. Alternate Uses: Resources are not only scarce but can be put to various uses. This makes the choice between alternative uses of given resources more important to ensure maximum satisfaction.

Economics as a Social Science

• Comprehensive Definition: "Economics is a social science which studies the way a society chooses to use its limited resources, which have alternate uses, to produce goods and services and to distribute them among different groups of people."

• Classification as a Science:

  • The term 'Science' implies any systematic and organised body of knowledge. Economics is a science because it is a systematic study of the economic behaviour of humans.

  • Why 'Social' Science?: Unlike Physics or Chemistry, Economics is not an "exact" science because it deals specifically with unpredictable human behaviour. Thus, it is classified as a social science.

Positive vs. Normative Economics

• Positive Economics (or Science): Deals with facts and things as they are.

  • Focus: Studies what the economic problems are and how they are actually solved.

  • Examples: "India is an overpopulated country (over $140$ crore+)" or "Prices are constantly rising."

  • Verification: Positive statements can be verified as true or false by comparing them with actual data.

  • Scenario (Chinki and Billu): Chinki says India is larger than China in land area. Billu says China is larger than India. Both are positive statements. Billu is factually right and Chinki is factually wrong, but both statements are "positive" because they can be tested against data.

  • Neutrality: Positive economics is neutral between ends. It might state that cigarettes are injurious to health (fact) without providing a judgment on whether they should be banned.

• Normative Economics (or Science): Tells us "what ought to be" or "what should be."

  • Focus: Deals with how economic problems should be solved.

  • Examples: "India should not be an overpopulated country" or "Prices should not rise."

  • Value Judgements: It is based on individual opinions and is suggestive in nature.

• Comparative Table of Positive and Normative Economics:

Practical Exercises: Classifying Statements

• Statement 1: "Increasing the minimum wage leads to higher unemployment among young workers." → Positive (Can be tested/verified).

• Statement 2: "The government should increase spending on healthcare to improve public well-being." → Normative (Involves a "should"/opinion).

• Statement 3: "A rise in interest rates reduces consumer spending." → Positive.

• Statement 4: "We ought to reduce income inequality to create a fairer society." → Normative ("Ought to").

• Statement 5: "Higher taxes on cigarettes reduce smoking rates." → Positive.

• Statement 6: "Taxes on the rich should be increased to fund social programs." → Normative.
