Starting your college journey with Economics is an exciting step. For Semester-I students, Introductory Micro-Economics is the most important subject. Many students find graphs and mathematical theories a bit difficult at first. However, it is a very logical subject. If you understand the basics, you can master the entire syllabus easily. This guide by PMG Classes will help you understand every concept deeply.
We have designed this blog to provide a complete deep-dive into the Sem-I syllabus. At PMG Classes, we believe in making complex topics simple. Whether you are preparing for exams or building a career, this guide is for you.

What is Micro-Economics?
Micro-economics is the study of small economic units. It focuses on individuals and private firms. It looks at how people make choices with limited resources. For example, why does a consumer buy a certain product? How does a company decide its price? These are micro-level questions.
In Semester-I, you study the behavior of consumers and producers. Understanding these units is the foundation of all economic studies.
1. The Central Problems of an Economy
Every economy faces a basic problem called Scarcity. Resources like land, labor, and money are limited. However, human wants are unlimited. This leads to three main questions:
What to Produce? Which goods are needed most?
How to Produce? Should we use more labor or more machines?
For Whom to Produce? Who gets the final goods and services?
To explain this, we use the Production Possibility Curve (PPC). The PPC shows the maximum output an economy can produce. It also highlights Opportunity Cost. This is the cost of the next best alternative that you give up.

2. Consumer Behavior and Demand
Demand Analysis is a major part of the Semester-I syllabus. Demand is not just a wish. It is the desire for a product backed by the power to pay.
The Law of Demand
The Law of Demand is simple. When the price goes up, demand goes down. When the price goes down, demand goes up. There is an Inverse Relationship between price and quantity.
Factors Affecting Demand:
Income of the Consumer: More money leads to more demand.
Price of Related Goods: This includes Substitutes (like Tea and Coffee).
Tastes and Preferences: What is trendy today.
Deep Dive into Utility Analysis
In Introductory Micro-Economics, we study how a consumer gets satisfaction. This is called Utility. There are two main ways to study this:
Cardinal Utility: This says we can measure satisfaction in numbers (Utils). This was promoted by Alfred Marshall.
Ordinal Utility: This says we can only rank our preferences (Higher or Lower). This was given by Hicks and Allen.
The Law of Diminishing Marginal Utility (DMU): This is a very famous law in Economics. It states that as you consume more units of a good, the extra satisfaction (Marginal Utility) starts falling. For example, the first glass of water gives you huge relief. But the fourth glass gives very little satisfaction. This law is the foundation of the Law of Demand.
3. Elasticity of Demand
Elasticity measures “how much” demand changes when the price changes. Not all goods react in the same way.
Price Elasticity: Change due to price.
Income Elasticity: Change due to income.
Cross Elasticity: Change due to the price of another good.
Degrees of Elasticity:
Perfectly Elastic: Small price change leads to infinite demand change.
Perfectly Inelastic: Demand does not change (like medicine).
Unitary Elastic: Price and demand change by the same percentage.
Practical Importance of Price Elasticity
Why do students need to study elasticity so deeply? It has real-world uses:
Business Pricing: If a product is ‘Inelastic’ (like salt), the company can increase the price without losing customers.
Government Taxes: The government puts higher taxes on goods that have inelastic demand, like cigarettes or petrol.
International Trade: It helps in deciding the terms of trade between two countries.
At PMG Classes, we don’t just teach the formula. We teach you how to analyze these trends in the real market. This deep understanding helps you score better in your Semester-I exams.
4. Supply and Market Equilibrium
Supply is the behavior of the producer. Unlike demand, supply has a Direct Relationship with price. If the price is high, producers want to sell more to earn more profit.
Market Equilibrium
Equilibrium happens when Demand equals Supply. At this point, there is no shortage in the market. The price fixed here is called the Equilibrium Price.
5. Production, Costs, and Markets
In this section, we study how firms make goods. We look at the Short Run and Long Run.
Law of Variable Proportions
This law says that as you add more labor to fixed land, the extra output will eventually fall. It is a key concept for every producer.
Market Structures
We compare different types of markets:
Perfect Competition: Many sellers, identical products.
Monopoly: Only one seller (like Railways).
Monopolistic: Many sellers with different brands (like Toothpaste).
Oligopoly: A few big sellers (like Automobiles).
