The Average Variable Cost Curve Essay Example
The average variable cost (AVC) in the short run and long run is ‘U’ shaped.

Average variable cost is the total variable cost per unit of output, found by dividing total variable cost by the quantity of output. Thus if a firm produces X2 units of a commodity at a total variable cost of TVx2 the AVC of producing these two units of output is given as

Average variable cost decreases with additional production at relatively small quantities of output and then eventually increases with relatively larger quantities of output. This pattern is illustrated by a U-shaped average variable cost curve. Average variable cost curve is a curve that graphically represents the relation between average variable cost incurred by a firm in the short-run production of a good or service and the quantity produced. This curve is constructed to capture the relation between average variable cost and the level of output, holding other variables, like technology and resource prices, constant. The AVC curve is ‘U’ shaped because the falling portion of the AVC curve reflects an improvement in the use of available resources due to specialization and division of labour however the rising portion of the AVC curve is a result of the law states that as continuous amounts of a variable factor of production is combined with a given amount of another fixed factor of production. Eventually the marginal productivity and the average productivity of the firm will fall. The falling productivity of factors corresponds to arising variable cost. This graph is the average variable cost curve for the short-run production of bracelets. The quantity of bracelets production, measured on the horizontal axis, ranges from 0 to 10 and the average variable cost incurred in the production of bracelets, measured on the vertical axis, ranges from a high of $5 to a low of $2.50, before rising again.

As noted above, the average variable cost curve is U-shaped. For the first 6 bracelets,

    Variable costs are those costs that increase as the output the restaurant increases. As example, assume for the Teen Burger Direct Materials cost $1.50 per burger. A day with one thousand burgers sold would cost of $1500 dollars. In comparison, a day with two thousand burgers sold would cost $3000 dollars. While the cost per Teen Burger remains constant the total cost per day varies with the output each given day. Electricity costs would increase in the same fashion as each time a burger is cooked the usage of electricity for heating would increase. Assuming four cooks can produce 1000 Teen Burgers, five can produce 2000, and six can produce 3000 in a day wages would also increase in the same fashion. If production only moves from 2600 to 2700 burgers the Direct Labour costs will remain fixed, this type behavior, as visible in the chart to the right, is called a step variable (Bragg, 2014). The dotted line is the trend, if we graphed the number of teen burgers to the Cost of Direct materials it would take the same straight line shape. The number of attendees at the register tracks approximate the same number of employees and number of Teen Burger sales, But is a period variable cost. Any cost that goes up as a direct result of an increase in output would…

    Basic Concepts 1. The relationship between the quantity of output (such as wheat, steel, or automobiles) and the quantities of inputs (of labor, land, and capital) is called the production function. Total product is the total output produced. Average product equals total output divided by the total quantity of inputs. We can calculate the marginal product of a factor as the extra output added for each additional unit of input while holding all other inputs constant. 2. According to the law of diminishing returns, the marginal product of each input will generally decline as the amount of that input increases, when all other inputs are held constant. 3. The returns to scale reflect the impact on output of a balanced increase in all inputs. A technology in which doubling all inputs leads to an exact doubling of outputs displays constant returns to scale. When doubling inputs leads to less than double (more than double) the quantity of output, the situation is one of decreasing (increasing) returns to scale. 4. Because decisions take time to implement, and because capital and other factors are often very long lived, the reaction of production may change over different time periods. The short run is a period in which variable factors, such as labor or material inputs, can be easily changed but fixed factors cannot. In the long run, the capital stock (a firm's machinery and factories) can depreciate and be replaced. In the long run, all inputs, fixed and variable, can be adjusted. 5. Technological change refers to a change in the underlying techniques of production, as occurs when a new product or process of production is invented or an old product or process is improved. In such situations, the same output is produced with fewer inputs or more output is produced with the same inputs. Technological change shifts the production function…

    In most organizations short run and long runs are divided into production process which has an effect on variable cost. The short run some inputs are fixed therefore the firm is constrained to what production decisions it can make. In the long run process all inputs are fixed therefore a firm can choose from several other production processes. There is no time period for a short run or a long run but since labor cost is a variable the firm has limited flexibility when changing the level of output. Variable cost has a U-shape in the short run the output will increase by increasing variable input. Other affecting factors are the higher the wage, the lower the quantity of labor demanded. With the fixed input the more variable inputs you add such labor the more likely the input is going to fall.…

    In the short run, both average total cost (ATC) and marginal cost (MC) will increase. Based on the law of diminishing marginal returns, when products expand, the return of per unit product is decreasing. On the on the other hand both MC and ATC are increasing. The examples in this case are The nature of the problems which can arise from this can be seen in the case of the increase in the cost of bananas associated with Cyclone Larry.
