Perfect Competition vs Monopoly: Market Extremes
The two ends of the market spectrum. One has zero power, the other has absolute power.
head-to-Head Comparison
| Basis | Perfect Competition | Monopoly |
|---|---|---|
| Number of Sellers | Large number (Infinite) | Single Seller (One) |
| Product Nature | Homogeneous (Identical) | Unique (No close substitutes) |
| Price Control | Price Taker (Market sets price) | Price Maker (Firm sets price) |
| Entry Barriers | Free Entry & Exit | Strong Barriers to Entry |
| Demand Curve | Perfectly Elastic (Horizontal) | Downward Sloping (Inelastic) |
The 'Price Discrimination' Trap
Only a Monopoly (or imperfect market) can practice Price Discrimination. A Perfect Competitor cannot charge different prices because buyers have perfect knowledge and products are identical.
Common Ground (Similarities)
- Both aim to maximize profit (MR = MC).
- Both shut down if Price < AVC in short run.
