3/4 Marker Questions

1. State any three characteristics of a perfectly competitive market.

Ans: The key characteristics of a perfectly competitive market are:

1. Large Number of Buyers and Sellers – The market consists of many buyers and sellers, and no individual firm can influence the market price.
2. Homogeneous Product – All firms produce identical goods, so buyers do not differentiate between products.
3. Freedom of Entry and Exit – Firms can freely enter or leave the market depending on profitability, ensuring no long-term abnormal profits or losses.

2. Why is a firm under perfect competition a price-taker? Explain.

Ans: A firm under perfect competition is a price-taker due to the following reasons:

1. Large Number of Firms – Since many firms are producing the same good, no single firm can influence the price.
2. Homogeneous Products – All firms sell identical products, so buyers have no preference for one firm over another.
3. Perfect Knowledge – Buyers and sellers have complete knowledge about prices, preventing firms from charging different prices.
   Thus, the price is determined by the forces of demand and supply in the market, and firms must accept it.

3. Explain the implications of ‘freedom of entry and exit of firms’ under perfect competition.

Ans: The freedom of entry and exit of firms leads to the following implications:

1. No Abnormal Profits in the Long Run – If firms earn supernormal profits, new firms will enter, increasing supply and reducing prices.
2. No Long-Term Losses – If firms incur losses, some firms will exit the market, reducing supply and raising prices.
3. Optimal Allocation of Resources – Resources are used efficiently as firms enter or exit based on profitability.
4. Market Equilibrium Maintained – This ensures that prices remain stable in the long run, benefiting both producers and consumers.

4. Explain the implication of homogeneous product features of perfect competition.

Ans: The homogeneous product feature of perfect competition leads to the following effects:

1. No Price Differentiation – Since all firms produce identical goods, consumers have no reason to prefer one firm over another.
2. Perfect Substitutes – Buyers can switch between sellers without any difference in product quality.
3. Firms Cannot Influence Price – Since products are identical, firms cannot charge a higher price than the market price.
4. No Need for Advertising – Firms do not need to spend on advertising because consumers already know that all products are identical.

5. State 3 features of a monopoly market. Describe anyone.

Ans: The key features of a monopoly market are:

1. Single Seller – There is only one seller of the product, with no close substitutes.
2. No Close Substitutes – Consumers cannot switch to alternative products, giving the monopolist full control over pricing.
3. Barriers to Entry – New firms cannot enter the market easily due to legal, technical, or financial restrictions.

Description of “Single Seller”:
A monopoly market consists of a single firm that controls the entire supply of a good or service. As there is no competition, the monopolist has significant power to determine price and output levels.

6. State three features of monopolistic competition.

Ans: The main features of monopolistic competition are:

1. Large Number of Buyers and Sellers – Many firms compete in the market, but each has a small share of the total market.
2. Product Differentiation – Firms sell slightly different products based on brand, quality, or other unique factors.
3. Freedom of Entry and Exit – New firms can enter the market easily while existing firms can leave without major restrictions.

7. State any two features of monopoly and monopolistic competition.

Ans:
Features of Monopoly:

1. Single Seller – The entire industry is controlled by one firm, with no direct competition.
2. Price Maker – The monopolist decides the price, as there are no competitors.

Features of Monopolistic Competition:

1. Product Differentiation – Each firm sells a product that is slightly different from others, creating brand loyalty.
2. Many Sellers – Several firms operate in the market, but each has some degree of market power due to product uniqueness.

8. Explain the implication of the product differentiation feature of monopolistic competition.

Ans: The product differentiation feature of monopolistic competition has the following implications:

1. Consumer Choice – Buyers get a variety of similar but slightly different products, allowing them to choose based on preference.
2. Brand Loyalty – Firms develop loyal customers by highlighting the unique features of their products through advertising.
3. Limited Price Control – Since products are differentiated, firms can charge slightly different prices without losing all customers.
4. Increased Advertising and Marketing – Firms spend on branding, packaging, and advertisements to promote their products.

9. What is meant by a product being perfectly homogeneous? What is its implication for the price charged by producers in the market?

Ans:
A perfectly homogeneous product means that all firms in the market produce identical goods with no variation in quality, design, or features. Consumers cannot differentiate between products from different sellers.

Implication for Price:

• Since all products are identical, no firm can charge a higher price than others.
• Consumers will always buy from the seller offering the lowest price.
• As a result, all firms in a perfectly competitive market must accept the market price, making them price-takers.

10. Explain the implication of ‘perfect knowledge about the market’ under perfect competition.

Ans:
Perfect knowledge means that buyers and sellers have complete information about prices, product quality, and market conditions.

Implications:

1. No Firm Can Charge a Higher Price – Buyers know the prevailing market price, so firms cannot overcharge.
2. Uniform Pricing – Since all firms sell homogeneous products and buyers have perfect knowledge, the price remains the same across all sellers.
3. No Advantage to Any Firm – Since all firms have access to the same technology and information, no firm can produce at a significantly lower cost.

11. State three features of Oligopoly.

Ans:

1. Few Large Firms – The market is dominated by a small number of large firms, each holding a significant market share.
2. Interdependence of Firms – Since there are few competitors, the actions of one firm (such as changing price or output) directly affect the others.
3. Barriers to Entry – High setup costs, brand loyalty, and legal restrictions prevent new firms from entering easily.

12. Why is the demand curve under monopolistic competition more elastic as compared to the demand curve under monopoly?

Ans:
The demand curve under monopolistic competition is more elastic because:

1. Availability of Close Substitutes – Consumers can easily switch to similar products if the price of one increases.
2. Large Number of Sellers – Many firms compete in the market, making it easier for consumers to find alternatives.
3. Less Market Power – Each firm has some control over price due to product differentiation, but they still face competition, unlike a monopoly where a single seller controls the market.

In contrast, a monopoly faces a less elastic demand curve because there are no close substitutes, giving the firm more power to set prices.

Conclusion

In the Economics exam, the weightage of this chapter is only 4-5 marks. Therefore, the possibility of a long question of 6 marks from this chapter in the Economics exam is very low. Hence, I haven’t included long answer questions.
