Economics 101: Perfect Competition
Josel Pineda・3 minutes read
Perfect competition is a market structure with many firms offering identical products, where market price is influenced by supply and demand, and firms can earn normal or supernormal profits in the short and long run, respectively. It comes with benefits like no barriers to entry and perfect knowledge, but drawbacks like limited innovation incentives and research and development investment.
Insights
- Perfect competition involves numerous firms selling identical products, with easy entry and exit, preventing any single entity from controlling prices, which are dictated by market forces of supply and demand.
- While short-term normal profits are feasible in perfect competition, long-term outcomes may lead to either supernormal profits or losses, prompting adjustments in supply curves and prices, highlighting the trade-offs of no barriers to entry and perfect information against limited incentives for innovation and research investment.
