Study Notes
Perfect Competition and Production
- A firm's profit can be increased by decreasing the price, but only if it leads to an increase in sales that outweighs the decrease in price.
- A perfectly competitive firm will earn a profit and continue producing in the short run if the price is greater than average variable cost, but less than average total cost.
Characteristics of Perfect Competition
- In a perfectly competitive industry, each firm is a price-taker and produces a standardized product.
- Individual firms cannot alter the market price, even if they double their output.
- The market sets the price, and each firm can take it or leave it.
Revenue and Cost
- Total revenue is the firm's total output times the price at which it sells that output.
- The difference between total revenue and total cost is economic profit or loss.
- Marginal revenue is the change in total revenue resulting from the sale of one more unit of output.
Production and Cost
- The total product curve shows the relation between output and the quantity of a variable input for varying levels of the fixed input.
- If a firm increases production from 10 units to 11 units and the market price is $20 per unit, total revenue for 10 units is $200.
- Average fixed cost is total fixed cost divided by the number of units produced.
Labour and Production
- The total product of labour is the total output produced by a certain number of workers.
- The marginal product of labour is the change in total product resulting from the addition of one more worker.
- Fixed inputs in a production function are those that do not change with the level of production, such as the dining room in a deli.
