The Allegheny County Library Association (ACLA) is an organization based in Western Pennsylvania. Formed in 1991, as an effort to encourage county libraries to collaborate and share resources, ACLA became recognized as a non-profit in 1994. ACLA is based in Pittsburgh's West End neighborhood.
103-534: ACLA has 46 member libraries. ACLA's story began in 1991 when the County Controller's office issued “A Quiet Crisis: Libraries in Allegheny County.” The report detailed the dismal state of County libraries, each working independently of one another without any centralized coordination or communication structure. The report challenged the collective community to increase funding to improve services. In response
206-460: A company gains an added benefit by expanding its size. These economies are due to the presence of some resource or competence that is not fully utilized, or to the existence of specific market positions that create a differential advantage in expanding the size of the firms. That growth economies disappear once the scale size expansion process is completed. For example, a company that owns a supermarket chain benefits from an economy of growth if, opening
309-465: A complex interaction of factors. Some of the most important immediate factors include technological change , organizational change, industry restructuring and resource reallocation, as well as economies of scale and scope. A nation's average productivity level can also be affected by the movement of resources from low-productivity to high-productivity industries and activities. Over time, other factors such as research and development and innovative effort,
412-591: A differentiated demand with respect to the quality of the product, and assistance before and after the sale. Very different organizational forms can therefore co-exist in the same sector of activity, even in the presence of economies of scale, such as, for example, flexible production on a large scale, small-scale flexible production, mass production, industrial production based on rigid technologies associated with flexible organizational systems and traditional artisan production. The considerations regarding economies of scale are therefore important, but not sufficient to explain
515-693: A driver of productivity itself. There is also considerable evidence to support improved productivity through operant conditioning reinforcement, successful gamification engagement, and research-based recommendations on principles and implementation guidelines for using monetary rewards effectively. Workplace bullying results in a loss of productivity, as measured by self-rated job performance . Over time, targets of bullying will spend more time protecting themselves against harassment by bullies and less time fulfilling their duties. Workplace incivility has also been associated with diminished productivity in terms of quality and quantity of work. A toxic workplace
618-421: A firm's costs, returns to scale describe the relationship between inputs and outputs in a long-run (all inputs variable) production function. A production function has constant returns to scale if increasing all inputs by some proportion results in output increasing by that same proportion. Returns are decreasing if, say, doubling inputs results in less than double the output, and increasing if more than double
721-437: A knowledge worker to seemingly produce more in a day than was previously possible in a year. Environmental factors such as sleep and leisure play a significant role in work productivity and received wage. Drivers of productivity growth for creative and knowledge workers include improved or intensified exchange with peers or co-workers, as more productive peers have a stimulating effect on one's own productivity. Productivity
824-404: A measure of the economic growth of nations and industries. GDP is the income available for paying capital costs, labor compensation, taxes and profits. Some economists instead use gross value added (GVA); there is normally a strong correlation between GDP and GVA. The measure of input use reflects the time, effort and skills of the workforce. The denominator of the ratio of labour productivity,
927-427: A more efficient division of labour. The economies of division of labour derive from the increase in production speed, from the possibility of using specialized personnel and adopting more efficient techniques. An increase in the division of labour inevitably leads to changes in the quality of inputs and outputs. Many administrative and organizational activities are mostly cognitive and, therefore, largely independent of
1030-407: A new supermarket, it gets an increase in the price of the land it owns around the new supermarket. The sale of these lands to economic operators, who wish to open shops near the supermarket, allows the company in question to make a profit, making a profit on the revaluation of the value of building land. Overall costs of capital projects are known to be subject to economies of scale. A crude estimate
1133-496: A product X is lower when a single firm instead of two separate firms produce it. See Economies of scope#Economics . Some of the economies of scale recognized in engineering have a physical basis, such as the square–cube law , by which the surface of a vessel increases by the square of the dimensions while the volume increases by the cube. This law has a direct effect on the capital cost of such things as buildings, factories, pipelines, ships and airplanes. In structural engineering,

#17328631872201236-566: A production unit or a company, yet, the object of modelling is substantially wider and the information more aggregate. The calculations of productivity of a nation or an industry are based on the time series of the SNA, System of National Accounts . National accounting is a system based on the recommendations of the UN (SNA 93) to measure the total production and total income of a nation and how they are used. International or national productivity growth stems from
1339-419: A ratio of an aggregate output to a single input or an aggregate input used in a production process, i.e. output per unit of input, typically over a specific period of time. The most common example is the (aggregate) labour productivity measure, one example of which is GDP per worker. There are many different definitions of productivity (including those that are not defined as ratios of output to input) and
1442-547: A relationship somewhat similar to the square–cube law. In some productions, an increase in the size of the plant reduces the average variable cost, thanks to the energy savings resulting from the lower dispersion of heat. Economies of increased dimension are often misinterpreted because of the confusion between indivisibility and three-dimensionality of space. This confusion arises from the fact that three-dimensional production elements, such as pipes and ovens, once installed and operating, are always technically indivisible. However,
1545-461: A result, numerous studies have indicated that the procurement volume must be sufficiently high to provide sufficient profits to attract enough suppliers, and provide buyers with enough savings to cover their additional costs. However, Shalev and Asbjornse found, in their research based on 139 reverse auctions conducted in the public sector by public sector buyers, that the higher auction volume, or economies of scale, did not lead to better success of
1648-540: A serious detrimental impact on productivity in an organisation. In companies where the traditional hierarchy has been removed in favor of an egalitarian, team-based setup, the employees are often happier, and individual productivity is improved (as they themselves are better placed to increase the efficiency of the workfloor). Companies that have these hierarchies removed and have their employees work more in teams are called liberated companies or "Freedom Inc.'s". The Kaizen system of bottom-up, continuous improvement
1751-528: A stable source of operating support and establish a broad based organization to take advantage of potential economies of scale . A Commission on the Future of Libraries in Allegheny County (CFLAC) was charged with addressing the recommendations in the report. Out of the commission's work, came the formation of the Allegheny County Library Association (ACLA). Twenty-five years later, ACLA, with
1854-733: A unit of capacity of many types of equipment, such as electric motors, centrifugal pumps, diesel and gasoline engines, decreases as size increases. Also, the efficiency increases with size. Operating crew size for ships, airplanes, trains, etc., does not increase in direct proportion to capacity. (Operating crew consists of pilots, co-pilots, navigators, etc. and does not include passenger service personnel.) Many aircraft models were significantly lengthened or "stretched" to increase payload. Many manufacturing facilities, especially those making bulk materials like chemicals, refined petroleum products, cement and paper, have labor requirements that are not greatly influenced by changes in plant capacity. This

When average costs start falling as output increases, then economies of scale occur. Some economies of scale, such as capital cost of manufacturing facilities and friction loss of transportation and industrial equipment, have a physical or engineering basis . The economic concept dates back to Adam Smith and
2060-445: Is a correlating relationship between a firm's total sales and underlying efficiency. Firms with higher productivity will always outperform a firm with lower productivity which will lead to lower sales. Through trade liberalization, organizations are able to drop their trade costs due to export growth. However, trade liberalization does not account for any tariff reduction or shipping logistics improvement. However, total economies of scale
2163-627: Is a historically contingent fact, and not essential to the nature of such enterprises. In the case of agriculture, for example, Marx calls attention to the sophistical nature of the arguments used to justify the system of concentrated ownership of land: Instead of concentrated private ownership of land, Marx recommends that economies of scale should instead be realized by associations : Alfred Marshall notes that Antoine Augustin Cournot and others have considered "the internal economies [...] apparently without noticing that their premises lead inevitably to

GDP is, for this purpose, only a very rough measure. Maximizing GDP, in principle, also allows maximizing capital usage. For this reason, GDP is systematically biased in favour of capital intensive production at the expense of knowledge and labour-intensive production. The use of capital in

While employees are distracted by this, they cannot devote time and attention to the achievement of business goals. When toxic employees leave the workplace, it can improve the culture overall because the remaining staff become more engaged and productive. The presence of a workplace psychopath may have

At a firm or industry level, the benefits of productivity growth can be distributed in a number of different ways: Productivity growth is important to the firm because it means that it can meet its (perhaps growing) obligations to workers, shareholders, and governments (taxes and regulation), and still remain competitive or even improve its competitiveness in
2575-477: Is based on the exporters individual frequency and size. So large-scale companies are more likely to have a lower cost per unit as opposed to small-scale companies. Likewise, high trade frequency companies are able to reduce their overall cost attributed per unit when compared to those of low-trade frequency companies. 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
2678-411: 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. Karl Marx noted that large scale manufacturing allowed economical use of products that would otherwise be waste. Marx cited

In fact, the competitive advantages deriving from the development of the firm's capabilities and from the management of transactions with suppliers and customers can counterbalance those provided by the scale, thus counteracting

An effective or knowledgeable supervisor (for example a supervisor who uses the Management by objectives method) has an easier time motivating their employees to produce more in quantity and quality. An employee who has an effective supervisor, motivating them to be more productive is likely to experience a new level of job satisfaction thereby becoming

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. Economies of scale exist whenever the total cost of producing two quantities of

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: internal and external. An industry that exhibits an internal economy of scale
3502-608: Is saturating the regional market, thus having to ship products uneconomic distances. Other limits include using energy less efficiently or having a higher defect rate. Large producers are usually efficient at long runs of a product grade (a commodity) and find it costly to switch grades frequently. They will, therefore, avoid specialty grades even though they have higher margins. Often smaller (usually older) manufacturing facilities remain viable by changing from commodity-grade production to specialty products. Economies of scale must be distinguished from economies stemming from an increase in

In estimating capital cost, it typically requires an insignificant amount of labor, and possibly not much more in materials, to install a larger capacity electrical wire or pipe having significantly greater capacity. The cost of

Mass production dramatically reduced the labor in producing parts for and assembling the automobile, but after its widespread adoption productivity gains in automobile production were much lower. A similar pattern was observed with electrification , which saw
3914-446: Is the measure of labour productivity (and all that this measure takes into account) which helps explain the principal economic foundations that are necessary for both economic growth and social development. In general labour productivity is equal to the ratio between a measure of output volume (gross domestic product or gross value added) and a measure of input use (the total number of hours worked or total employment). The output measure
4017-438: Is typically net output, more specifically the value added by the process under consideration, i.e. the value of outputs minus the value of intermediate inputs. This is done in order to avoid double-counting when an output of one firm is used as an input by another in the same measurement. In macroeconomics the most well-known and used measure of value-added is the gross domestic product or GDP. Increases in it are widely used as

Economies of scale is a concept that may explain patterns in international trade or in the number of firms in a given market.

Constant changes in technology, pressure on the Allegheny Regional Asset District to fund a wider range of assets, the growing demands of residents for current information and new formats, and the continued need to diversify library funding are just a few issues that remain. However, the main foundation of county-wide cooperation has been established, allowing ACLA and its members to reach their goals.

With the “Information Age” emerging, libraries were struggling to keep up in providing residents with quick access to research materials and critical resources. Allegheny County also

It was one of the charter contractual assets to receive funding through the Allegheny Regional Asset District (ARAD). Allegheny County has 130 independent municipalities, making large-scale cooperation rare and extremely difficult. Yet ACLA has succeeded in becoming a model for delivering service across municipal boundaries. 2016 marked

When multiple inputs are considered, the measure is called multi-factor productivity or MFP. Multi-factor productivity is typically estimated using growth accounting . If the inputs specifically are labor and capital, and the outputs are value added intermediate outputs,
4738-671: The GDP-measure is considered to be as valuable as the production's ability to pay taxes, profits and labor compensation. The bias of the GDP is actually the difference between the GDP and the producer income. Another labour productivity measure, output per worker, is often seen as a proper measure of labour productivity, as here: "Productivity isn't everything, but in the long run it is almost everything. A country's ability to improve its standard of living over time depends almost entirely on its ability to raise its output per worker." This measure (output per worker) is, however, more problematic than

Over long periods of time, small differences in rates of productivity growth compound, like interest in a bank account, and can make an enormous difference to a society's prosperity. Nothing contributes more to reduction of poverty, to increases in leisure, and to the country's ability to finance education, public health, environment and
4944-511: The advantages of external economies linked to an increase in the production of an entire sector of activity. However, "those economies which are external from the point of view of the individual firm, but internal as regards the industry in its aggregate, constitute precisely the class which is most seldom to be met with." "In any case - Sraffa notes – in so far as external economies of the kind in question exist, they are not linked to be called forth by small increases in production," as required by

This stimulated a whole series of studies on the cases of imperfect competition in Cambridge. However, in the succeeding years Sraffa followed a different path of research that brought him to write and publish his main work Production of commodities by means of commodities ( Sraffa 1966 ). In this book, Sraffa determines relative prices assuming no changes in output, so that no question arises as to

They noted, however, that their data included a wide range of products, and the degree of competition in each market varied significantly, and offer that further research on this issue should be conducted to determine whether these findings remain
5253-431: The average cost for all firms as opposed to internal economies of scale which only allows benefits to the individual firm. Advantages that arise from external economies of scale include; Firms are able to lower their average costs by buying their inputs required for the production process in bulk or from special wholesalers. Firms might be able to lower their average costs by improving their management structure within

#17328631872205356-434: The base of dynamic economies of scale, associated with the process of growth of the scale dimension and not to the dimension of scale per se. Learning by doing implies improvements in the ability to perform and promotes the introduction of incremental innovations with a progressive lowering of average costs. Learning economies are directly proportional to the cumulative production ( experience curve ). Growth economies emerge if
5459-627: The biggest gains are normally from adopting new technologies, which may require capital expenditures for new equipment, computers or software. Modern productivity science owes much to formal investigations that are associated with scientific management . Although from an individual management perspective, employees may be doing their jobs well and with high levels of individual productivity, from an organizational perspective their productivity may in fact be zero or effectively negative if they are dedicated to redundant or value destroying activities. In office buildings and service-centred companies, productivity
5562-508: The capitalist system is therefore characterized by two tendencies, connected to economies of scale: towards a growing concentration and towards economic crises due to overproduction. In his 1844 Economic and Philosophic Manuscripts , Karl Marx observes that economies of scale have historically been associated with an increasing concentration of private wealth and have been used to justify such concentration. Marx points out that concentrated private ownership of large-scale economic enterprises
5665-452: The chemical industry as an example, which today along with petrochemicals, remains highly dependent on turning various residual reactant streams into salable products. 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. Large and more productive firms typically generate enough net revenues abroad to cover
5768-1039: The choice among them depends on the purpose of the productivity measurement and data availability. The key source of difference between various productivity measures is also usually related (directly or indirectly) to how the outputs and the inputs are aggregated to obtain such a ratio-type measure of productivity. Productivity is a crucial factor in the production performance of firms and nations. Increasing national productivity can raise living standards because increase in income per capita improves people's ability to purchase goods and services, enjoy leisure, improve housing, and education and contribute to social and environmental programs. Productivity growth can also help businesses to be more profitable. Productivity measures that use one class of inputs or factors , but not multiple factors, are called partial productivities. In practice, measurement in production means measures of partial productivity. Interpreted correctly, these components are indicative of productivity development, and approximate
5871-425: The conclusion that, whatever firm first gets a good start will obtain a monopoly of the whole business of its trade … ". Marshall believes that there are factors that limit this trend toward monopoly, and in particular: Piero Sraffa observes that Marshall, in order to justify the operation of the law of increasing returns without it coming into conflict with the hypothesis of free competition, tended to highlight

Allegheny County's libraries have many more resources at their disposal and are better positioned to meet the increased demand from residents for services in education and community enhancement. While it is important to celebrate the success over
6077-447: The cost advantages that enterprises obtain due to their scale of operation, and are typically measured by the amount of output produced per unit of time . A decrease in cost per unit of output enables an increase in scale that is, increased production with lowered cost. At the basis of economies of scale, there may be technical, statistical, organizational or related factors to the degree of market control. Economies of scale arise in
6180-610: The development of human capital through education, and incentives from stronger competition promote the search for productivity improvements and the ability to achieve them. Ultimately, many policy, institutional and cultural factors determine a nation's success in improving productivity. At the national level, productivity growth raises living standards because more real income improves people's ability to purchase goods and services (whether they are necessities or luxuries), enjoy leisure, improve housing and education and contribute to social and environmental programs. Some have suggested that
6283-462: The economies of scale due to the increase in size do not depend on indivisibility but exclusively on the three-dimensionality of space. Indeed, indivisibility only entails the existence of economies of scale produced by the balancing of productive capacities, considered above; or of increasing returns in the utilisation of a single plant, due to its more efficient use as the quantity produced increases. However, this latter phenomenon has nothing to do with
SECTION 60
#17328631872206386-434: The economies of scale which, by definition, are linked to the use of a larger plant. At the base of economies of scale there are also returns to scale linked to statistical factors. In fact, the greater of the number of resources involved, the smaller, in proportion, is the quantity of reserves necessary to cope with unforeseen contingencies (for instance, machine spare parts, inventories, circulating capital, etc.). One of
6489-504: The economy-wide level of aggregation, that this function has neoclassical smoothness and curvature properties, that inputs are paid the value of their marginal product, that the function exhibits constant returns to scale, and that technical change has the Hicks’n neutral form. In practice, TFP is "a measure of our ignorance", as Abramovitz (1956) put it, precisely because it is a residual. This ignorance covers many components, some wanted (like
6592-493: The effects of technical and organizational innovation), others unwanted (measurement error, omitted variables, aggregation bias, model misspecification) Hence the relationship between TFP and productivity remains unclear. When all outputs and inputs are included in the productivity measure it is called total productivity. A valid measurement of total productivity necessitates considering all production inputs. If we omit an input in productivity (or income accounting) this means that
6695-521: The efficiency with which inputs are used in an economy to produce goods and services. However, productivity is only measured partially – or approximately. In a way, the measurements are defective because they do not measure everything, but it is possible to interpret correctly the results of partial productivity and to benefit from them in practical situations. At the company level, typical partial productivity measures are such things as worker hours, materials or energy used per unit of production. Before
6798-422: The factors underlying the ever-increasing concentration of capital. Marx observes that in the capitalist system the technical conditions of the work process are continuously revolutionized in order to increase the surplus by improving the productive force of work. According to Marx, with the cooperation of many workers brings about an economy in the use of the means of production and an increase in productivity due to
6901-410: The firm increase, the notions of increasing returns to scale and economies of scale can be considered equivalent. However, if input prices vary in relation to their quantities purchased by the company, it is necessary to distinguish between returns to scale and economies of scale. The concept of economies of scale is more general than that of returns to scale since it includes the possibility of changes in
7004-518: The firm is a perfect competitor in all input markets, and thus the per-unit prices of all its inputs are unaffected by how much of the inputs the firm purchases, then it can be shown that at a particular level of output, the firm has economies of scale if and only if it has increasing returns to scale, has diseconomies of scale if and only if it has decreasing returns to scale, and has neither economies nor diseconomies of scale if it has constant returns to scale. In this case, with perfect competition in
7107-454: The firm is so big in one or more input markets that increasing its purchases of an input drives up the input's per-unit cost, then the firm could have diseconomies of scale in that range of output levels. 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. In essence, returns to scale refer to
7210-515: The firm. This can range from hiring better skilled or more experienced managers from the industry. Technological advancements change production processes and subsequently reduce the overall cost per unit. Tim Hindle argues that the rollout of the internet "has completely reshaped the assumptions underlying economies of scale". Productivity Productivity is the efficiency of production of goods or services expressed by some measure. Measurements of productivity are often expressed as
7313-435: The fixed costs associated with exporting. However, in the event of trade liberalization, resources will have to be reallocated toward the more productive firm, which raises the average productivity within the industry. Firms differ in their labor productivity and the quality of their products, so more efficient firms are more likely to generate more net income abroad and thus become exporters of their goods or services. There
7416-604: The founder of political economy as an autonomous discipline. John Stuart Mill , in Chapter IX of the First Book of his Principles, referring to the work of Charles Babbage (On the economics of machines and manufactories), widely analyses the relationships between increasing returns and scale of production all inside the production unit. In Das Kapital (1867), Karl Marx , referring to Charles Babbage , extensively analyzed economies of scale and concludes that they are one of
7519-994: The highest productivity gains in the early decades after introduction. Many other industries show similar patterns. The pattern was again followed by the computer, information and communications industries in the late 1990s when much of the national productivity gains occurred in these industries. There is a general understanding of the main determinants or drivers of productivity growth. Certain factors are critical for determining productivity growth. The Office for National Statistics (UK) identifies five drivers that interact to underlie long-term productivity performance: investment, innovation, skills, enterprise and competition . Research and development (R&D) tends to increase productivity growth, with public R&D showing larger spillovers and smaller firms experiencing larger productivity gains from public R&D. Technology has enabled massive personal productivity gains—computers, spreadsheets, email, and other advances have made it possible for
7622-438: The idea of obtaining larger production returns through the use of division of labor. Diseconomies of scale are the opposite. Economies of scale often have limits, such as passing the optimum design point where costs per additional unit begin to increase. Common limits include exceeding the nearby raw material supply, such as wood in the lumber, pulp and paper industry . A common limit for a low cost per unit weight commodities
7725-479: The increase in the division of labour. Furthermore, the increase in the size of the machinery allows significant savings in construction, installation and operation costs. The tendency to exploit economies of scale entails a continuous increase in the volume of production which, in turn, requires a constant expansion of the size of the market. However, if the market does not expand at the same rate as production increases, overproduction crises can occur. According to Marx
7828-419: The individual phases of the production process. If the inputs are indivisible and complementary, a small scale may be subject to idle times or to the underutilization of the productive capacity of some sub-processes. A higher production scale can make the different production capacities compatible. The reduction in machinery idle times is crucial in the case of a high cost of machinery. A larger scale allows for
7931-401: The input measure is the most important factor that influences the measure of labour productivity. Labour input is measured either by the total number of hours worked of all persons employed or total employment (head count). There are both advantages and disadvantages associated with the different input measures that are used in the calculation of labour productivity. It is generally accepted that
8034-424: The marginalist theory of price. Sraffa points out that, in the equilibrium theory of the individual industries, the presence of external economies cannot play an important role because this theory is based on marginal changes in the quantities produced. Sraffa concludes that, if the hypothesis of perfect competition is maintained, economies of scale should be excluded. He then suggests the possibility of abandoning
8137-470: The market place. Adding more inputs will not increase the income earned per unit of input (unless there are increasing returns to scale). In fact, it is likely to mean lower average wages and lower rates of profit. But, when there is productivity growth, even the existing commitment of resources generates more output and income. Income generated per unit of input increases. Additional resources are also attracted into production and can be profitably employed. In
8240-510: The measure is called total factor productivity (TFP]. TFP measures the residual growth that cannot be explained by the rate of change in the services of labour and capital. MFP replaced the term TFP used in the earlier literature, and both terms continue in use (usually interchangeably). TFP is often interpreted as a rough average measure of productivity, more specifically the contribution to economic growth made by factors such as technical and organisational innovation. The most famous description
8343-419: The measurement of productivity shall be developed so that it "will indicate increases or decreases in the productivity of the company and also the distribution of the ’fruits of production’ among all parties at interest". According to Davis, the price system is a mechanism through which productivity gains are distributed, and besides the business enterprise, receiving parties may consist of its customers, staff and
8446-584: The most immediate sense, productivity is determined by the available technology or know-how for converting resources into outputs, and the way in which resources are organized to produce goods and services. Historically, productivity has improved through evolution as processes with poor productivity performance are abandoned and newer forms are exploited. Process improvements may include organizational structures (e.g. core functions and supplier relationships), management systems, work arrangements, manufacturing techniques, and changing market structure. A famous example
8549-454: The omitted input can be used unlimitedly in production without any impact on accounting results. Because total productivity includes all production inputs, it is used as an integrated variable when we want to explain income formation of the production process. Davis has considered the phenomenon of productivity, measurement of productivity, distribution of productivity gains, and how to measure such gains. He refers to an article suggesting that
8652-411: The output market the long-run equilibrium will involve all firms operating at the minimum point of their long-run average cost curves (i.e., at the borderline between economies and diseconomies of scale). If, however, the firm is not a perfect competitor in the input markets, then the above conclusions are modified. For example, if there are increasing returns to scale in some range of output levels, but
8755-475: The output. If a mathematical function is used to represent the production function, and if that production function is homogeneous , returns to scale are represented by the degree of homogeneity of the function. Homogeneous production functions with constant returns to scale are first degree homogeneous, increasing returns to scale are represented by degrees of homogeneity greater than one, and decreasing returns to scale by degrees of homogeneity less than one. If
8858-405: The presence of significant economies of scale. This contradiction, between the empirical evidence and the logical incompatibility between economies of scale and competition, has been called the 'Cournot dilemma'. As Mario Morroni observes, Cournot's dilemma appears to be unsolvable if we only consider the effects of economies of scale on the dimension of scale. If, on the other hand, the analysis
8961-450: The price of inputs when the quantity purchased of inputs varies with changes in the scale of production. The literature assumed that due to the competitive nature of reverse auctions , and in order to compensate for lower prices and lower margins, suppliers seek higher volumes to maintain or increase the total revenue. Buyers, in turn, benefit from the lower transaction costs and economies of scale that result from larger volumes. In part as
9064-569: The production of a given plant. When a plant is used below its optimal production capacity , increases in its degree of utilization bring about decreases in the total average cost of production. Nicholas Georgescu-Roegen (1966) and Nicholas Kaldor (1972) both argue that these economies should not be treated as economies of scale. The simple meaning of economies of scale is doing things more efficiently with increasing size. Common sources of economies of scale are purchasing (bulk buying of materials through long-term contracts), managerial (increasing
9167-400: The reasons firms appear is to reduce transaction costs . A larger scale generally determines greater bargaining power over input prices and therefore benefits from pecuniary economies in terms of purchasing raw materials and intermediate goods compared to companies that make orders for smaller amounts. In this case, we speak of pecuniary economies, to highlight the fact that nothing changes from
9270-441: The same when purchasing the same product for both small and high volumes. Keeping competitive factors constant, increasing auction volume may further increase competition. The first systematic analysis of the advantages of the division of labour capable of generating economies of scale, both in a static and dynamic sense, was that contained in the famous First Book of Wealth of Nations (1776) by Adam Smith , generally considered
9373-426: The scale of production. When the size of the company and the division of labour increase, there are a number of advantages due to the possibility of making organizational management more effective and perfecting accounting and control techniques. Furthermore, the procedures and routines that turned out to be the best can be reproduced by managers at different times and places. Learning and growth economies are at
9476-427: The size of the company and the market structure. It is also necessary to take into account the factors linked to the development of capabilities and the management of transaction costs. External economies of scale tend to be more prevalent than internal economies of scale. Through the external economies of scale, the entry of new firms benefits all existing competitors as it creates greater competition and also reduces
9579-412: The slowdown have been proposed there is no consensus. The matter is subject to a continuing debate that has grown beyond questioning whether just computers can significantly increase productivity to whether the potential to increase productivity is becoming exhausted. In order to measure the productivity of a nation or an industry, it is necessary to operationalize the same concept of productivity as in
9682-446: The specialization of managers), financial (obtaining lower- interest charges when borrowing from banks and having access to a greater range of financial instruments), marketing (spreading the cost of advertising over a greater range of output in media markets ), and technological (taking advantage of returns to scale in the production function). Each of these factors reduces the long run average costs (LRAC) of production by shifting
9785-449: The strength of beams increases with the cube of the thickness. 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 loss from industrial processes vary per unit of volume for pipes, tanks and other vessels in
9888-483: The suppliers of production inputs. In the main article is presented the role of total productivity as a variable when explaining how income formation of production is always a balance between income generation and income distribution. The income change created by production function is always distributed to the stakeholders as economic values within the review period. Productivity growth is a crucial source of growth in living standards. Productivity growth means more value
9991-399: The tendency towards a monopoly inherent in economies of scale. In other words, the heterogeneity of the organizational forms and of the size of the companies operating in a sector of activity can be determined by factors regarding the quality of the products, the production flexibility, the contractual methods, the learning opportunities, the heterogeneity of preferences of customers who express
10094-593: The total number of hours worked is the most appropriate measure of labour input because a simple headcount of employed persons can hide changes in average hours worked and has difficulties accounting for variations in work such as a part-time contract , paid leave , overtime , or shifts in normal hours. However, the quality of hours-worked estimates is not always clear. In particular, statistical establishment and household surveys are difficult to use because of their varying quality of hours-worked estimates and their varying degree of international comparability. GDP per capita
10197-417: The variation in the relationship between inputs and output . This relationship is therefore expressed in "physical" terms. But when talking about economies of scale, the relation taken into consideration is that between the average production cost and the dimension of scale. Economies of scale therefore are affected by variations in input prices. If input prices remain the same as their quantities purchased by
10300-556: The variation or constancy of returns. In 1947, DuPont engineer Roger Williams, Jr. (1930-2005) published a rule of thumb that costs of chemical process are roughly proportional to the tonnage in power ~0.6 . In the following decades it became widely adopted other engineering industries and terrestrial mining, sometimes (e. g., in electrical power generation) with modified exponential scaling factors. It has been noted that in many industrial sectors there are numerous companies with different sizes and organizational structures, despite
10403-452: The widespread use of computer networks, partial productivity was tracked in tabular form and with hand-drawn graphs. Tabulating machines for data processing began being widely used in the 1920s and 1930s and remained in use until mainframe computers became widespread in the late 1960s through the 1970s. By the late 1970s inexpensive computers allowed industrial operations to perform process control and track productivity. Today data collection
10506-575: Was first practiced by Japanese manufacturers after World War II, most notably as part of The Toyota Way . Productivity is one of the main concerns of business management and engineering. Many companies have formal programs for continuously improving productivity, such as a production assurance program. Whether they have a formal program or not, companies are constantly looking for ways to improve quality, reduce downtime and inputs of labor, materials, energy and purchased services. Often simple changes to operating methods or processes increase productivity, but
10609-459: Was ranked at the bottom for per capita dollars spent on libraries throughout the nation. The report included recommendations in the form of 10 steps (outlined below) for better citizen access and to address several key challenges – insufficient funding, deteriorating facilities, a shift in population from the urban core, and increasing use of the independent suburban libraries. The report concluded that Allegheny County's libraries needed to identify
