第四篇 Perfect Competition
Perfect competition exists in an industry that contains many relatively samll firms producing identical products.The most importhant characteristic(特征) of a perfectly competitive industry if that no single firm has any control over prices.This important characteristic follows from two assumptions(假设).First, a competitive industry is composed of many firms, each being very samll relative to the size of the industry .S***nd ,every firm in a perfectly competitive industry producse exactly the same product.
Firms in perfectly competitive industries do not differentiate(区分) their products, nor do they make decisions about price.Rather,each firm takes prices as given-that is ,as determined in the market by the laws of supply and demand -and decides olny how much to produce and how to produce it.Given the availability(可得性) of perfect substitutes, any product priced over the market price will not be sold .
In perfectcompetition we also assume that firms can freely enter and exit the industry.The assumption of free entry implies that if firms in an industry are earning excessively high profits,new firms that seek to do the same thing are likely to spring up.Fast food restaurants are quick to spring up when a new shopping center opens.Where profit opportunities present themselves, we assume that firms sill enter and compete for them.
Free exit is possible when firms can simply stop producing their products and leave a market .Generally speaking,a firm closes dowm because it is suffering losses or because profits are insufficient .New England textile and furniture products found themselves facing increasing foreign competition, as well as lower production costs in the South .While some firms packed up and moved ,others simply got out of the business altogether.
