returns to scale describes the relationship between media

The so-called 'production function' describes the relationship between input The explanation for increasing returns to scale in the media industry lies in the. Economies of scale concerns with mainly two variables: Cost & Output. Increasing economies of scale describes the phenomenon of a firm facing lower average. In the long run all costs are variable and the scale of production can change (i.e. no fixed inputs); Economies of scale are the cost advantages from expanding.

The output is apples.

Law of Returns to Scale

Where Q is the maximum quantity of output and X1, X2,… Xn are the quantities of the various inputs. From the above equation, we can understand that the production function tells us the relationship between various inputs and outputs.

However, it does not say anything about the combination of inputs. The optimal combination of inputs can be derived from the technique of isoquant and isocost line. The concept of production function stems from the following two things: It must be considered with reference to a particular period. It is determined by the state of technology. Any change in technology may alter output, even when the quantities of inputs remain fixed. Law of Returns to Scale In the long- run the dichotomy between fixed factor and variable factor ceases.

In other words, in the long-run all factors are variable.

The law of returns to scale examines the relationship between output and the scale of inputs in the long-run when all the inputs are increased in the same proportion. Assumptions This law is based on the following assumptions: All the factors of production such as land, labor and capital but organization are variable The law assumes constant technological state.

Returns to scale

It means that there is no change in technology during the time considered. The exploitation of economies of scale helps explain why companies grow large in some industries.

It is also a justification for free trade policies, since some economies of scale may require a larger market than is possible within a particular country—for example, it would not be efficient for Liechtenstein to have its own carmaker if they only sold to their local market.

A lone carmaker may be profitable, but even more so if they exported cars to global markets in addition to selling to the local market.

Economies of scale also play a role in a " natural monopoly ". There is a distinction between two types of economies of scale: An industry that exhibits an internal economy of scale is one where the costs of production fall when the number of firms in the industry drops, but the remaining firms increase their production to match previous levels.

Conversely, an industry exhibits an external economy of scale when costs drop due to the introduction of more firms, thus allowing for more efficient use of specialized services and machinery. The management thinker and translator of the Toyota Production System for service, Professor John Seddonargues that attempting to create economies by increasing scale is powered by myth in the service sector.

In trying to manage and reduce unit costs, firms often raise total costs by creating failure demand. Seddon claims that arguments for an economy of scale are a mix of a the plausibly obvious and b a little hard data, brought together to produce two broad assertions, for which there is little hard factual evidence.

This law has a direct effect on the capital cost of such things as buildings, factories, pipelines, ships and airplanes.

Drag loss of vehicles like aircraft or ships generally increases less than proportional with increasing cargo volume, although the physical details can be quite complicated. Therefore, making them larger usually results in less fuel consumption per ton of cargo at a given speed.

Heat losses from industrial processes vary per unit of volume for pipes, tanks and other vessels in a relationship somewhat similar to the square-cube law.

A crude estimate is that if the capital cost for a given sized piece of equipment is known, changing the size will change the capital cost by the 0.

Also, the efficiency increases with size. Many aircraft models were significantly lengthened or "stretched" to increase payload.

  • Economies of scale

This is because labor requirements of automated processes tend to be based on the complexity of the operation rather than production rate, and many manufacturing facilities have nearly the same basic number of processing steps and pieces of equipment, regardless of production capacity. Economical use of byproducts[ edit ] Karl Marx noted that large scale manufacturing allowed economical use of products that would otherwise be waste.

In the pulp and paper industry it is economical to burn bark and fine wood particles to produce process steam and to recover the spent pulping chemicals for conversion back to a usable form. Economies of scale and returns to scale[ edit ] Economies of scale is related to and can easily be confused with the theoretical economic notion of returns to scale. Where economies of scale refer to a firm's costs, returns to scale describe the relationship between inputs and outputs in a long-run all inputs variable production function.
