Understanding Perfect Competition

Brad Cartwright explains productive and allocative efficiency in perfect competition. In the long run, firms make normal profits, and the market achieves maximum resource allocation. Firms are price takers, and the industry curve shows demand, supply, and price relationships. Productive efficiency occurs where MC equals AC, and allocative efficiency is where MC equals AR. Profit maximization happens where MC equals MR. Perfect competition is ideal for understanding firm behavior with no barriers to entry or exit, and firms sell homogeneous products.
