1. Introduction: What is a “Method of Economic Study”?
The word “Method” comes from the Greek word Methodos, which means “a path or way of investigation.”
In Economics, Methods of Economic Study (or Economic Methodology) refer to the scientific procedures and logical steps that economists use to:
- Discover cause-and-effect relationships between economic events (e.g., between price and demand, or between money supply and inflation).
- Formulate general Economic Laws and Theories.
- Test whether those theories work in the real business world.
2. The Two Fundamental Approaches to Economic Study
There are two main scientific approaches (methods) used to formulate economic laws:
- The Deductive Method (Moving from General Truth → Particular Case)
- The Inductive Method (Moving from Particular Observations → General Law)
3. Understanding Both Methods Through Everyday Analogies
Before diving into textbook definitions, let’s understand the difference in 30 seconds using a simple analogy:
Example 1: The Gravity / Apple Analogy
- Inductive Approach (Bottom-Up): You watch an apple fall from a tree to the ground. Then you drop a stone, a ball, and a pen — and record that all of them fall downward. From these 100 specific observations, you conclude the general law: “All objects with mass are pulled toward the Earth.”
- Deductive Approach (Top-Down): You start with the already-known general law: “All objects with mass are pulled toward the Earth.” Then you hold a mobile phone in your hand and logically conclude (deduce) without even dropping it: “Since this phone has mass, if I let go of it, it will fall to the ground!”
4. Classroom Activity 2: Real-Life Business Examples of Inductive & Deductive Methods
(As prescribed in the DAVV BBA Syllabus — Unit 3, Activity 2: “Students in groups will discuss real-life examples of the inductive and deductive methods based on observation. For the inductive method, they might explore how a shopkeeper notices higher ice cream sales on hot days. For the deductive method, they could consider how a company increases prices based on the theory that higher prices can lead to higher profit.”)
Here are two detailed real-life business case studies that you can present in class and write in your DAVV exam:
Case A: Real-Life Example of the Inductive Method (Particular Facts → General Rule)
Scenario: An Ice-Cream Parlour Owner in Indore
- Why is this Inductive? Because the shopkeeper did not start with a textbook theory! He started with particular real-world observations and daily sales bills, noticed a consistent statistical pattern, and moved upward to form a general business rule.
- Another Classic Economic Law Built by Induction:
- Engel’s Law of Family Expenditure: German statistician Ernst Engel collected actual household budget data from hundreds of working-class families and discovered the general law: “As a family’s income increases, the percentage of income spent on food decreases, while the percentage spent on education, recreation, and luxury increases.”
Case B: Real-Life Example of the Deductive Method (General Theory → Particular Decision)
Scenario: A Luxury Smartphone Brand (or Pharmaceutical Company) Setting Prices
- Why is this Deductive? Because the manager started from a general, established economic theory (Inelastic Demand / Profit Maximization) and applied logical reasoning to predict what will happen in their specific company’s case.
- Classic Economic Laws Built by Deduction:
- Law of Diminishing Marginal Utility (DMU)
- Law of Demand
- Law of Equi-Marginal Utility
- Ricardian Theory of Rent
💡 DAVV Exam Tip
Question (5 Marks): “What are the approaches to economic study? Illustrate Inductive and Deductive approaches with real-life examples.”
- Always state the direction arrows clearly:
- Deductive = General → Particular (Theory to Fact)
- Inductive = Particular → General (Fact to Theory)
- Include the Ice-Cream Shopkeeper example for Induction and the Company Pricing example for Deduction!
