Definition§
A duopoly is a market structure where two companies have significant market power and control over the supply of a product or service. This setup can lead to similar outcomes as a monopoly, particularly if the two firms collude to set prices or output levels, leaving consumers with fewer choices and potentially higher prices.
Duopoly vs Monopoly Comparison§
| Feature | Duopoly | Monopoly |
|---|---|---|
| Number of Firms | Two | One |
| Market Control | Joint power; possible collusion | Complete power without competition |
| Consumer Choice | Limited but present | Non-existent |
| Pricing Influence | Can influence prices if colluding | Full control over price setting |
| Market Entry | Difficult due to established players | Almost impossible for new entrants |
