Price Taker & Demand Curve
Characteristics of Perfect Competition
In a perfectly competitive market, there are many small firms selling identical products. Everyone knows the market price, and no firm can charge more than others. Because entry and exit are easy, competition keeps prices low and efficiency high.
All firms in perfect competition are price takers. The market establishes the price, and each firm produces its product at the same price. The firm's demand curve is perfectly elastic in the sense that it can make any quantity at the market price but cannot set above the price.
Short-Run & Real-World Examples
Profit Maximization
In the short run, firms in perfect competition can earn profits or losses depending on their costs. Over time, new firms enter or leave the market until only normal profit remains. Real-world examples include agriculture, fisheries, and street markets, where prices are set by supply and demand.
Firms in perfect competition maximize profit where marginal cost equals marginal revenue (MC = MR). At this point, producing more would increase cost faster than revenue, and producing less would lose potential profit.
