Study Notes
Profit Maximization
- Firms aim to maximize profit, defined as total revenue minus total cost.
- Revenue is the price per unit multiplied by the quantity sold.
- Profit is a function of quantity (Q).
- Profit maximization occurs when marginal revenue (MR) equals marginal cost (MC).
Marginal Revenue (MR) and Marginal Cost (MC)
- Marginal cost (MC) is the cost of producing one more unit.
- Marginal revenue (MR) is the revenue generated by producing one more unit.
- Profit maximization occurs when MR = MC.
Profit Maximization in Perfect Competition
- In perfect competition, firms are "price takers," meaning they cannot influence the market price.
- Marginal revenue (MR) is equal to the market price (p).
- Profit is maximized when market price (p) equals marginal cost (MC).
Short-Run Supply Curve
- The firm's short-run supply curve is the portion of the marginal cost curve that lies above the average variable cost (AVC) curve.
- If market price falls below average variable cost (AVC), the firm will shut down in the short-run and produce zero output.
Long-Run Decision
- In the long run, firms can adjust all inputs, including fixed costs (e.g., capital).
- Exit the market if Average Revenue (AR) or Price (P) is less than Average Cost (AC).
- Enter the market if price (P) is greater than Average Cost (AC).
Connecting Cost Minimization and Profit Maximization
- To maximize profit, a firm first minimizes its cost of producing a given output level.
- The cost-minimizing input combination (capital and labor) is determined by equating the ratio of marginal product to input price for each input.
