Study Notes

Perfect Competition

Characterized by multiple vendors supplying a commodity or service.
Easy entry and exit for vendors in the market.
No single vendor can influence the market price due to the presence of many competitors.

Monopoly

Defined as the complete opposite of perfect competition.
Exists when a unique product or service is available from a single vendor.
The monopolist can prevent other vendors from entering the market, controlling supply and pricing.

Oligopoly

Involves a market structure with very few suppliers.
The actions of one supplier significantly impact the responses of others in the market.
Typically results in interdependence among firms, leading to coordinated pricing and output decisions.

The Law of Diminishing Returns

States that increasing one factor of production, while others are fixed, will eventually lead to decreased additional output.
As variable factors are increased, a point is reached where output increases at a slower rate.
Important for understanding production efficiency and resource allocation in economics.
