Study Notes
Pure Competition Characteristics
- Large number of sellers leads to independence and perfect information among competitors.
- Products are standardized, making consumers indifferent; they seek the lowest price with no brand loyalty.
- Freedom of entry and exit allows firms to enter or leave the market freely based on their desires.
- Price takers exist due to the vast number of sellers; individual firms cannot influence pricing, as the market dictates it.
Demand Curve and Revenue
- The demand curve within pure competition is perfectly elastic, indicating that firms can sell as much as they desire at the market price.
- In a pure competition structure, price equals demand (P = D) and marginal revenue (MR), reflecting a balance in market dynamics.
Profit Maximization
- Profit maximization occurs where the difference between total revenue and total cost is maximized, identified by the condition MC = MR.
- Short-run profit maximization exists when average costs (AC) are below the demand curve, indicating potential profits.
Short-Run Outcomes
- Profits are maximized at the intersection of marginal cost and marginal revenue. The quantity where AC intersects demand defines potential profits.
- Short-run losses arise when average costs exceed the demand curve, leading to a situation where costs are higher than prices.
Shutdown Conditions
- Firms may choose to remain open even during losses if average variable costs (AVC) are below the demand curve (P > AVC).
- A firm should close if its AVC is above the demand curve (P < AVC).
Monopoly Characteristics
- Monopolists act as price makers, controlling both the quantity of goods sold and the price, making the market equivalent to the firm.
- In pure monopoly, the demand curve is inelastic and downward sloping, with marginal revenue falling below demand allowing for potential excess pricing.
Regulation of Monopolies
- Regulation aims to improve monopolistic efficiency and find a compromise where prices are reduced but still above average costs.
Graphical Representation in Pure Competition
- Graphically, profits are maximized at the greatest distance between total revenue and total cost curves.
- In pure competition, marginal revenue equals product price, ensuring a direct correlation between the two.
Long-Run Equilibrium
- A purely competitive firm achieves long-run equilibrium when marginal revenue equals marginal cost, price equals marginal cost, and total revenue aligns with total cost.
- The condition of minimum average total cost equaling price indicates an efficient allocation of resources.
Firm Objectives
- Firms aim to maximize total profit, seeking the highest total revenue in relation to total costs.
- In the short run, a competitive firm will produce at a level that maximizes the difference between total revenue and total costs.
