Study Notes
Characteristics of Perfect Competition
- Features a large number of buyers and sellers, ensuring no single entity can influence market prices.
- Products offered by all firms are homogeneous, meaning they are identical in nature, leading to consumer preference based on price.
- Free entry and exit allow firms to enter or leave the market without restrictions, fostering competition and efficiency.
- Perfect information is available to all parties, ensuring consumers and producers have complete awareness of prices and product quality.
- Firms prioritize profit maximization as their primary objective, driving them to optimize production and pricing strategies.
- The demand curve in perfect competition is horizontal, indicating that firms can sell any quantity of goods at the market price without affecting it.
Revenue Functions
- Total revenue (TR) represents the complete monetary income from sales, calculated as ( TR = P \times Q ), where ( P ) is price and ( Q ) is quantity sold.
- Average revenue (AR) indicates the revenue generated per unit sold, expressed as ( AR = \frac{TR}{Q} ).
- Marginal revenue (MR) measures the change in total revenue from selling one additional unit, given by ( MR = \frac{DTR}{DQ} ).
Revenue Equality in Perfect Competition
- In a perfectly competitive market, average revenue (AR), marginal revenue (MR), price (P), and demand (D) are all equal, reflecting the market's equilibrium conditions.
Definition of Monopoly
- Derived from Greek "Monos" (single) and "polus" (a seller).
- Represents a market structure dominated by one supplier.
Characteristics of Pure Monopoly
- Single Seller: Only one seller serves numerous buyers, creating a significant market presence.
- Price Maker: The monopolist controls the market price, setting it above marginal costs.
- Price Taker Consumers: Buyers must accept the price set by the monopolist as there are no alternatives.
- Lack of Substitutes: No close substitutes for the monopolist’s product, creating a unique market position.
- Demand Curve: Exhibits a downward sloping demand curve, indicating that as price decreases, quantity demanded increases.
- Price Discrimination: The ability to charge different prices to different consumers based on willingness to pay.
- Barriers to Entry: New competitors face significant obstacles, preventing them from entering the market freely.
Legal Restrictions
- Monopolies may be influenced by legal restrictions such as patent rights, which protect the monopolist's unique products from competition.
