When new firms enter a perfectly competitive market, several key entities are affected. The equilibrium price decreases, leading to a reduction in profits for existing firms. Entry of new firms increases the supply of goods, resulting in a decrease in the price. Furthermore, consumers benefit from lower prices and increased competition.
New Firm Entry in a Perfectly Competitive Market
When new firms enter a perfectly competitive market, the market structure undergoes significant changes that affect both existing firms and consumers. Here’s an in-depth explanation of the best structure for new firm entry:
Short-Run Impact
-
Increase in Supply: New firms add to the overall supply of goods or services, leading to a shift in the market supply curve to the right.
-
Lower Equilibrium Price: With increased supply, the equilibrium price decreases to a point where the quantity supplied equals the quantity demanded.
-
Elasticity of Demand: The elasticity of demand for the product determines the extent to which consumers respond to price changes. A high elasticity of demand means consumers are sensitive to price changes, and thus, a smaller price decrease is required to absorb the increased supply.
Long-Run Impact
-
Zero Economic Profit: In the long run, new firms will continue to enter the market until economic profits are zero. Economic profit is the difference between total revenue and total cost. In perfect competition, firms are price takers, meaning they have no control over the market price. Therefore, firms will only enter the market if they expect to earn at least normal profit, which is the minimum return required to keep them in operation.
-
Constant Returns to Scale: Perfectly competitive markets are characterized by constant returns to scale, which means that firms do not experience any cost advantages or disadvantages as they increase or decrease their production. This prevents any single firm from dominating the market.
-
Homogeneous Products: Products in perfectly competitive markets are identical or highly similar, so consumers have no preference for one firm’s product over another. This further promotes competition and prevents any firm from gaining a significant market share.
Table: Comparison of Market Structure Before and After New Firm Entry
| Characteristic | Before Entry | After Entry |
|---|---|---|
| Number of Firms | Fewer | More |
| Market Supply | Lower | Higher |
| Equilibrium Price | Higher | Lower |
| Economic Profit | Positive (for existing firms) | Zero |
| Constant Returns to Scale | No | Yes |
| Homogeneity of Products | No | Yes |
Conclusion:
New firm entry in a perfectly competitive market leads to increased competition, lower prices, and the elimination of economic profits in the long run. The structure of the market ensures that no firm has a dominant position and that consumers benefit from increased choice and lower prices.
Question 1:
What happens when new firms enter a perfectly competitive market?
Answer:
When new firms enter a perfectly competitive market, it leads to an increase in the overall supply of goods or services. This results in a shift in the market supply curve to the right. Consequently, the equilibrium price decreases, and the equilibrium quantity increases. The entry of new firms reduces the market share of existing firms, leading to a decrease in their profits. In the long run, firms may exit the market if they are unable to cover their costs.
Question 2:
How does the entry of new firms affect the efficiency of a perfectly competitive market?
Answer:
In a perfectly competitive market, the entry of new firms increases competition, which drives down prices and improves allocative efficiency. The increased competition incentivizes firms to produce at a lower cost and offer better-quality goods or services. Consumers benefit from lower prices and a wider variety of choices.
Question 3:
What are the factors that determine the number of firms that will enter a perfectly competitive market?
Answer:
The number of firms that will enter a perfectly competitive market is determined by the level of barriers to entry, the potential profits, and the expectations of future market conditions. Barriers to entry, such as high capital costs, government regulations, and patents, can limit the number of new firms that can enter a market. Potential profits attract firms to enter a market, while negative expectations about future market conditions can deter entry.
