Difference Between Long Run And Long-Run Production Planning

A company’s profit is affected by the amount of revenue it generates and the costs associated with production. When a company is deciding how much to produce, there are both short-run and long-run production periods. A short run is the current time span during which at least one fixed input must be paid whether or not any output is produced. A long run is a time period far enough into the future that all fixed inputs can be variable. Planning for the future involves looking at all possible situations which will maximize profit and minimize cost.
A production function shows the relationship between output and input, assuming the same technology. The goal is to achieve technical efficiency by producing the maximum possible output for a given …show more content…

An isoquant is a downward sloping curve which shows all possible combinations of inputs physically capable of producing a given level of output. If the two inputs are continuously divisible, there are endless combinations. The concept of an isoquant is that it’s possible to substitute some amount of one input for some of the other while maintaining the same level of output. The slope in the isoquant is referred to as the marginal rate of technical substitution. An isocost curve is a line that shows all combinations of inputs that may be purchased for a given level of expenditure at assumed input prices. If the constant level of total cost associated with a particular isocost curve changes, the isocost curve shifts parallel. If costs increase, assuming input prices remain constant, the curve shifts upward in parallel fashion. If costs decrease, assuming input prices remain constant, the curve shifts downward in parallel fashion. An isocost curve exists for each level of total cost. In order to maximize output for a given level of input cost, a manager must choose the amounts of labor and capital that result in the marginal rate of technical substitution and the input price ratio being …show more content…

There are numerous forces that can affect long-run costs, some controllable and some not. When long-run average cost falls as output increases, economies of scale occurs. Diseconomies of scale occurs when long-run average cost rises as output increases. Changes in technology and changes in input prices cannot be reasons for rising or falling unit costs. Larger companies can divide production into specialized tasks to allow workers to become more productive to achieve economies of scale. Unit costs can also decrease from quasi-fixed inputs that don’t change much as output increases. Technological factors, the costs of capital equipment and the qualitative change in production process can also contribute to economies of scale. When output increases, long-run average costs can rise if the firm has inefficient management and disorganization. The larger the scale of the production facility, the more critical it becomes to have top management who are able to delegate responsibility and authority to mid-level managers. To avoid diseconomies of scale, firms will divide production operations into separate divisions to control the cost of monitoring and control
