Economies of scale are traditionally characterised as "a drop in the long run average cots of yield as yield rises”. At the yield level O a firm would know-how the most effective scale of production (MES) and therefore would produce at the smallest cost grade of production. In characterising finances of scale we have to suppose "ceteris paribus", also that technology continues unchanging, as do factor costs and that there is greatest efficiency at every grade of output. (Barney, 2008)
In my opinion There are some causes why finances of scale exist. They can live due to increasing or declining (for diseconomies of scale) comes back to scale. These are known as mechanical economies. These happen from what occurs in the output process. Taking an demonstration of a appliance that produces fabric, which a small firm may use on mean 5 times a week. However a bigger firm may use the appliance 10 times a week. The total cost of the machine will be the same independent of if it is used 5 or 10 times per week, but the mean cost per unit of fabric made will be smaller the more times it is used. This is an demonstration of indivisibility. "The larger the level of yield, the less expected that indivisibilities will occur"(Sloman and Sutcliffe). This supposess that unit costs are constant.
I think smaller firms often have managers or workers who will do various jobs within the company. For demonstration the proprietor may be supervisor and the accountant, and even the salesman. However in bigger companies the employers will be more specialised and therefore will be more effective and therefore charges will be lower. These economies are called managerial economies. For demonstration if companies move into bigger manufacturers then there can be a partition of work which makes the process much more effective and decreases the indivisibilities. Also bigger companies will be adept to drive their goods through numerous phases in one factory, while smaller manufacturers would have to drive their goods to other manufacturers to be entired. For demonstration a large apparel business will be adept to produce the method="color: Red;">method="color: Red;">piece of method="color: Red;">method="color: Red;">piece of cloth, method="color: Red;">method it and print patterns all in the identical factory.

Another source of economies of scale are buying and marketing economies. Larger companies who purchase in bulk will be able to get lower charges for their raw materials. This is the identical for trading crusades, which larger firms will experience smaller average costs. Their crusades will be bigger and then will often be more thriving, and therefore obtain more 'value for cash' on these campaigns. For demonstration the cost of a TV financial will be the identical for a company with profits of £5 million per annum will be the identical as a business with profits of £40 million per annum.
Financial finances are another source. Smaller companies will often be ascribed at higher rates of interest on cash lent from the bank, ...
