## Econ 110 Chapters 13

When the marginal costs curve is below an average curve the average curve is falling. When a monopolist charges a single price, some consumers get positive consumer surplus, therefore the switch to perfect price discrimination reduces consumer surplus. Both average total cost and average fixed cost include fixed costs in their calculations. In the long run the firm can examine the average total cost curves associated with varying levels of capital. Contrary to Viner the envelope is not created by the minimum point of each short-run average cost curve. But, in the long-run, the firm can produce on a completely different cost curves to the left i.

## Cost Curves: With Diagram

The long run marginal cost curve intersects the long run average cost curve at the minimum point of the latter. In a free market economy, productively efficient firms use these curves to find the optimal point of production, where they make the most profits. Marginal Cost: Refer to the addition to the total cost for producing an additional unit of the product. However, as other barbers are added, the advantage of each additional barber is less since the specialization of labor can only go so far. The shape of the average variable cost curve is directly determined by increasing and then diminishing marginal returns to the variable input conventionally labour.

## Cost Curves: With Diagram

In economics, it expresses the idea that an economy behaves differently depending on the length of time it has to react to certain stimuli. The slope of the total cost curves equals marginal cost. The fourth column shows the variable costs at each level of output. The cost curves, whether short-run or long-run, are U-shaped because the cost of production first starts falling as output is increased owing to the various economies of scale. Conversely, if the firm is able to get bulk discounts of an input, then it could have economies of scale in some range of output levels even if it has decreasing returns in production in that output range. Diminishing marginal product refers to the fact that as the inputs to production increase, the marginal product declines, causing the production function to get flatter as output increases.

## Section 6: The Long

Fixed costs are expenditures that do not change based on the level of production, at least not in the short term. As a result, the total costs of production will begin to rise more rapidly as output increases. Answer: Regulate the firm's pricing behavior. When long-run average total cost declines as output increases, there are said to be economies of scale, as average total cost falls with rising output. The marginal cost curve is usually U-shaped. Answer: takes its price as given by market conditions Explanation: Because a perfectly competitive firm is small compared to the world market for the good it produces, it takes the price as given by market conditions. Variable costs, on the other hand, are incurred in the act of producingâ€”the more you produce, the greater the variable cost.

## Section 6: The Long

This means that the largest firm tends to have a cost advantage, and the industry tends naturally to become a monopoly, and hence is called a natural monopoly. On is to plot long-run average cost, which is, long-run total cost divided by the quantity of output produced. In this case, total cost divided by the number of units produced is equal to roughly. For example, Suppose a company observes a sudden surge in the demand for its goods and in order to meet the increased demand in the short-run, it can increase its level of output only by varying the variable factors. Marginal cost is important for deciding whether any additional output can be produced or not. But after touching the lowest point at the optimum output level, it starts rising, and goes on rising if production is continued beyond the optimum level.

## Section 6: The Long

By the long period, we mean the period during which the size and organisation of the firm can be altered to meet the changed conditions. An economist measures a firm's economic profit as the firm's total revenue minus all the opportunity costs explicit and implicit of producing the goods and services sold. These bottom portions of the different short-run cost curves make up the long-run average cost curve. Therefore, in the long-run equilibrium, price is equal to average total cost. In a perfectly competitive market the price that firms are faced with would be the price at which the marginal cost curve cuts the average cost curve. Answer:Average total cost would decrease. Next, we'll use the graph below to examine the relationship between the quantity of output being produced and the cost of producing that output.

## Short run Cost Curves

Such as, the company can employ more labor or purchase the raw material in bulk, but however, the plant size or the machinery cannot be altered to enhance the production capacity of the firm. But, as we have said already, the U-shape of the long-run cost curves is less pronounced. Explanation: If the firm produced a quantity for which demand was inelastic, then if the firm raised its price, quantity would fall by a smaller percentage than the rise in price, so revenue would increase. According to them, the shape of the long-run cost curve will be something as is given in Fig. The level of fixed costs varies according to the specific line of business. This is because fixed cost can never be zero. The slope of the variable cost function is marginal costs.

## Definition of long

In this case, producing one additional unit raises costs by. For each short-run fixed plant size, we take the lowest or near-lowest costs for that size plant. All costs are variable, so we do not distinguish between total variable cost and total cost in the long run: total cost is total variable cost. The long-run marginal cost curve intersects the long-run average cost curve at the minimum point of the latter. There are various types of cost curves, all related to each other.

. In each case, the firm in question will be producing the desired output at the lowest cost. An increase in fixed costs does not alter the marginal revenue or the marginal cost, therefore it does not affect the optimal level of output or the optimal price. This shape of the marginal cost curve is directly attributable to increasing, then decreasing marginal returns and the law of. The concept of long-run cost is also used in determining whether the firm will remain in the industry or shut down production there. Explanation: The monopolist's profit-maximizing quantity of output is determined by the intersection of the marginal-revenue curve and the marginal-cost curve. When a firm increases its output and observes increasing average total costs in the upward portion of the long-run average cost curve , it experiences diseconomies of scale.
