FAQs on Worksheet: The Theory of the Firm under Perfect Competition- 1 - Economics Class 11 - Commerce

1. What is the theory of the firm under perfect competition?
Ans. The theory of the firm under perfect competition is an economic concept that describes the behavior and decision-making process of a firm operating in a perfectly competitive market. In this theory, firms are assumed to be price takers, meaning they have no control over the market price and must accept it as given. They aim to maximize their profits by optimizing their production and cost decisions.
2. What are the characteristics of a perfectly competitive market?
Ans. A perfectly competitive market is characterized by several key features. Firstly, there are many buyers and sellers in the market, none of whom have significant market power to influence the price. Secondly, all firms in the market produce identical products, leading to perfect substitutability. Thirdly, there is free entry and exit of firms in the market, ensuring long-run equilibrium. Lastly, there is perfect information available to all market participants.
3. How does a firm determine its profit-maximizing level of output in perfect competition?
Ans. In perfect competition, a firm determines its profit-maximizing level of output by equating its marginal cost (MC) with the market price (P). As a price taker, the firm cannot influence the market price and must accept it as given. By producing at the level where MC equals P, the firm ensures that it minimizes costs and maximizes profits. Any level of output where MC is greater than P would lead to losses, while any level where MC is less than P would not be optimal.
4. What is the relationship between a firm's short-run and long-run profits in perfect competition?
Ans. In perfect competition, a firm can generate positive economic profits in the short run if the market price exceeds its average total cost (ATC). However, in the long run, due to the absence of barriers to entry, new firms can enter the market, increasing competition. This leads to an increase in supply, which eventually drives the market price down. As a result, firms in the long run earn zero economic profits, as the market price equals their average total cost.
5. How does perfect competition benefit consumers?
Ans. Perfect competition benefits consumers in multiple ways. Firstly, it ensures that consumers have access to a wide range of products at competitive prices. The presence of many sellers and perfect information allows consumers to make informed choices and select the best product for their needs. Additionally, the absence of market power among firms prevents them from charging excessive prices. This competition-driven market structure promotes efficiency, innovation, and consumer welfare.
