Study Notes
Perfect Competition
- Defined by a large number of buyers and sellers in the market.
- All producers sell identical products, leading to price uniformity.
- Producers act as price takers, with no power to influence market prices.
- There is freedom of entry and exit from the market, fostering competition.
- Minimal government intervention allows the market to operate freely.
- Market participants possess perfect information, enabling informed decisions.
- Firms aim to maximize profits, driving production and pricing strategies.
Profit Maximization Conditions
- Equilibrium occurs when profit (Ⲡ) is maximized, calculated using Ⲡ = TR - TC.
- TR stands for total revenue, while TC represents total cost.
- Profit maximization occurs at output level where Marginal Revenue (MR) equals Marginal Cost (MC).
- MR reflects the change in total revenue from selling one more unit of output.
- MC indicates the additional cost incurred from producing one additional unit.
- If MR exceeds MC, firms should increase production; if MR is less than MC, profits decline and production should be curbed.
Total Revenue-Total Cost Approach
- In the short run, firms may experience negative profits or abnormal profits.
- Long-run equilibrium leads to zero economic profits, as all inputs become variable.
- Competitive firms encounter a horizontal demand curve, influenced by market price (P).
- Demand curve for individual firms aligns with Average Revenue (AR) and Marginal Revenue (MR) curves: AR = MR = P.
- When Average Total Cost (ATC) falls below P, firms earn excess profits.
- If ATC exceeds P, firms incur losses but might continue production if price is above Average Variable Cost (AVC), known as the shutdown point.
- The short-run supply curve correlates with the MC curve above the P = AVC point.
Long-run Profit Maximization
- The Long-run Average Cost (LAC) curve illustrates economies and diseconomies of scale.
- Long-run Marginal Cost (LMC) curve intersects the LAC from below at its lowest point.
- Firms maximize profit by producing at a level where price (P) equals LMC, LAC, AR, and MR.
- Higher market prices correlate with increased profits.
- Firms have no incentive to enter or exit the market when all achieve zero economic profit.
