What is Economics?
Definitions: • Economics tells us how a man utilizes his limited
resources to satisfy his unlimited demands• Economics is the study of scarce resources and of
determination of income and employment• Economics is the science which studies human

Needs of Man
• Food Clothing and Shelter
• To get his basic needs he needs MONEY
• To Earn Money he needs to work or put efforts
Banshri Raichana 4
• Life Cycle

Economic Problems
Banshri Raichana 5
• Unlimited Wants Unending chain of Human wants
Efforts can never satisfy all wants1 need is satisfied there awaits 1 more
• Scarcity of meansMeans: Money, Energy, Time, Physical and Intellectual capacityScarcity: Availability is less than Need
• Alternative uses of meansMoney or time, One can satisfy either this want or that want but not bothEg: Family Time inc.. Rate of Income reduces.. And vice versa..

DEMAND and SUPPLY
“Demand for anything means the quantity of that commodity which is bought, at a given price, per unit of time”
“Supply is the amount of good that would be offered for sale at all prices at any one instant of time”
Banshri Raichana 8

Law of Demand
• Law of demand states that “ With other factors remaining constant
Demand EXTENDS at Lower Price &
Contracts at Higher Price”
• Demand inversely proportional to Price

Elasticity of Demand• Elasticity of Demand:
The change in demand for a commodity in response to a change in its price is called elasticity of demand.
• Types of Elasticity of Demand:
Price Elasticity (Inelastic, Unitary elasticity, Perfectly Elastic)
Income Elasticity (Income of consumers)
Cross Elasticity (one commodity to another)
Banshri Raichana 12

Factors determining Elasticity
• Durability and Nature of Commodity • Urgency of commodity• Advertising Effect• Proportion of Expenditure (news paper) • Consumer capability• Price and Change in price• Other substitute availability • Complementary goods
Banshri Raichana 13

Law of Supply
• It states that “ With other things being constant supply varies directly with its price”.
• When the price of a commodity rises its supply expands and when the price falls its supply reduces .
• A rise in price induces the producers to supply more because he can make more profits and vice versa

Market and Market Structure
• Perfect competition• Monopoly• Oligopoly• Monopolistic competition
Banshri Raichana 16
![Page 17: Industrial Economics and Telecommunication Regulations IETR Banshri Raichana1.](https://reader035.fdocuments.in/reader035/viewer/2022062717/56649e5d5503460f94b56467/html5/thumbnails/17.jpg)
Features of Perfect Competition
• Perfect knowledge• Free entry and exit• No government interference• No non-price competition• Large number buyers and sellers
Banshri Raichana 17
![Page 18: Industrial Economics and Telecommunication Regulations IETR Banshri Raichana1.](https://reader035.fdocuments.in/reader035/viewer/2022062717/56649e5d5503460f94b56467/html5/thumbnails/18.jpg)
Monopoly and its Merits
Monopoly:Control of single manufacturer over the entire market for a particular product.
Merits of Monopoly:• Price maker• Large number of consumers• Single manufacturer in Market• Entry to the market Restricted
Banshri Raichana 18
![Page 19: Industrial Economics and Telecommunication Regulations IETR Banshri Raichana1.](https://reader035.fdocuments.in/reader035/viewer/2022062717/56649e5d5503460f94b56467/html5/thumbnails/19.jpg)
Oligopoly and Monopolistic competition
• Oligopoly: Oligo means few and poly means sellers• The market form in which there are only a few sellers
is called oligopoly (homogeneous(physically similar products
Eg Pen) )• Monopolistic competition
In this system the number of dealers is quite large but not as large under perfect competition. (not homogeneous products)The same price does not rule in the market throughout.
Banshri Raichana 19
![Page 20: Industrial Economics and Telecommunication Regulations IETR Banshri Raichana1.](https://reader035.fdocuments.in/reader035/viewer/2022062717/56649e5d5503460f94b56467/html5/thumbnails/20.jpg)
Features of Monopoly• Only one seller or producer• Monopolists enjoy supernormal profits• No free entry to the seller in the market• Monopolists decides pricing and service conditions• No close substitute for the product or services
provided by the monopolist• Method of marketing: The monopolist’s needs to
Brand and Advertise his product depending on the threat of competition rather than actual competition

Price determination
• Under Perfect Competition
The above graph shows that the price under competitive conditions is the result of total demand for commodity and the total supply of the industry
Banshri Raichana 22

Definitions
• Marginal revenueIt is the extra revenue that an additional unit of product will bring It is the additional income from selling one more unit of a good; sometimes equal to price
• Marginal CostIt is the change in total cost that arises when the quantity produced changes by one unit

Definitions
• Average CostIs equal to the total cost divided by the total no of goods produced
• Average revenueThe revenue for selling a good per unit of output sold, found by dividing total revenue by the quantity of output

Forms of Price Discrimination• Personal Discrimination• Local Discrimination• Trade Discrimination• Quality Discrimination• Special Service Discrimination• Time Discrimination (Trunk Calls Day and Night charges)
