Pricing under Various Forms of Market
(Notes for Competitive Exams – JKSSB, UPSC, SSC | Home Academy)
1. Introduction
In economics, price is the amount of money paid for a good or service. The determination of price depends largely on the structure of the market in which a firm operates.
Market structure refers to the number of firms in the market, nature of competition, type of product, and degree of control over price.
The concept of market structure and price determination was discussed by economists such as Alfred Marshall and Joan Robinson.
Different market structures determine how firms set prices and compete with each other.
2. Meaning of Market
A market is a place or system where buyers and sellers interact to exchange goods and services and determine the price.
A market does not necessarily mean a physical place; it can also be online platforms, stock exchanges, or digital markets.
Example: agricultural markets, stock markets, and online shopping platforms.
3. Forms of Market
Economists generally classify markets into four major forms based on competition.
Perfect Competition
Monopoly
Monopolistic Competition
Oligopoly
4. Perfect Competition
Perfect competition is a market structure where many buyers and sellers trade identical products and no single firm can influence the market price.
In this market, price is determined by demand and supply.
