Study Notes
Perfect Competition Characteristics
- Many buyers and sellers participate, ensuring no single entity can dictate market prices.
- Firms sell homogeneous products that are identical across different suppliers.
- Consumers and producers are fully informed about prices and availability, promoting transparency.
- Firms and resources are freely mobile, allowing ease of entry and exit in the market.
Price Determination
- Price is established through the interaction of market supply and demand forces.
Price Taker Concept
- A perfectly competitive firm has no control over product pricing, accepting market prices as given.
Marginal Revenue
- Defined as the change in total revenue (TR) resulting from selling one additional unit of output.
Marginal Cost
- Defined as the change in total cost (TC) that occurs when producing one additional unit of output.
Maximizing Economic Profit
- A firm maximizes economic profit by measuring the distance between total cost and total revenue using average profit (AP) and quantity sold.
- Equating marginal revenue (MR) to marginal cost (MC) is a strategy for profit maximization.
Identifying Profit on Curves
- Profit in a perfectly competitive market is indicated by the vertical distance between total revenue (TR) and total cost (TC).
Identifying Loss on Curves
- A loss is signified when total cost (TC) surpasses total revenue (TR).
Relationship Between Price, Demand, Average Revenue, and Marginal Revenue
- In a perfectly competitive market, price (P), demand (D), average revenue (AR), and marginal revenue (MR) are all equal (P=D=AR=MR).
Demand Curve Characteristics
- The demand curve is perfectly elastic, represented as a horizontal line, indicating that price changes will not affect demand.
Total Revenue Curve Characteristics
- The total revenue (TR) curve slopes upward due to price takers, calculated by multiplying price (P) by quantity (Q).
Average Variable Cost Implications
- When price (P) is greater than average variable cost (AVC), firms can continue operating.
Break-Even Point
- When price equals average total cost (ATC), firms operate at break-even, earning a normal profit.
Economic Profit Situation
- When price exceeds average total cost (ATC), firms generate economic profits, attracting new suppliers into the market.
Long-Run Equilibrium
- In the long run, the presence of more suppliers drives profits back to the normal level as competition increases.
