80-523: Officially called the Société Européenne de Travaux et de Développement (ETD), the team was based in Paris. Founded to develop a shared range of light trucks, its main success was a shared cab design. Cabs can be one of the most expensive parts of a truck to design and build; the alliance allowed one cab design to be shared among four different truck manufacturers, allowing economies of scale . In 1978, Saviem

160-651: A Ferreyra in Argentina, and also assembled in Venezuela . The maximum gross weight ranged from 6 to 18 tons. Both of 4x2 and 4x4 (GVW 10 and 14 tons) were available. The Iveco Tector engines were used in many variants, including: R4, 3920 cc, 129–170 hp (96–127 kW; 131–172 PS); R6, 5880 cc, 182–275 hp (136–205 kW; 185–279 PS). There were 4 types of cabs available: Standard Time (MLC), extended bed (MLL, with one or two bunk beds), augmented bed and Extended Crew (MLD, for 7.5t to 15t models) for

240-460: 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

320-591: 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

400-555: A displacement of 5900 cc have powers from 217 to 299 hp (162 to 223 kW; 220 to 303 PS). All engines are Euro 5 compliant with SCR. The truck finished second in the competition for the title of International Truck of the Year 2009 . A new version of the Eurocargo was presented on 15 September 2015. The vehicle is produced at the Brescia plant. The shape of the new air intakes and

480-421: 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

560-427: 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

640-407: 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

720-496: 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,

800-560: A push to establish this brand in the British commercial vehicles' market. RVI trucks branded as Berliet carried the Club of Four cab as well in 1978–1979. The Club of Four cab was later adapted to Renault Midliner, Maxter, and Manager trucks. Renault C-series (including CLM, CBB and CBH, and also GBC 180 ) construction and military vehicles with conventional cabins adapted Club of Four cab as well. Renault Sherpa Medium family derived from CB-series

880-547: 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,

960-461: 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

1040-672: A similar number of ratios (5, 6, 9). The 6-speed versions of the ZF gearbox are also available with Eurotronic automatic or manual (sequential) gearboxes. To advertise the update special All Blacks versions were made. They are characterized by black paint and other details in this color. The engines are part of the Tector family of Fiat Powertrain Technologies . 4-cylinder engines with a displacement of 3900 cc have powers from 140 to 182 hp (104 to 136 kW; 142 to 185 PS). 6-cylinder engines with

1120-733: 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

1200-440: A variety of organizational and business situations and at various levels, such as a production, plant or an entire enterprise. 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

1280-445: 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

1360-627: 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

1440-477: 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

1520-411: 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

1600-424: Is expanded, including the aspects concerning the development of knowledge and the organization of transactions, it is possible to conclude that economies of scale do not always lead to monopoly. 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

1680-442: 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. Economies of scale exist whenever the total cost of producing two quantities of

1760-505: 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: internal and external. An industry that exhibits an internal economy of scale

1840-608: 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

1920-634: Is still in production (2019). Magirus intended to use the Club of Four cab on light trucks; this was inherited by Iveco as they took over the Magirus company before the cab entered production in Germany. The Iveco-built version was originally sold as the Magirus-Deutz MK range in Germany and certain other markets, this became the Magirus-Iveco in the early 1980s. Iveco, having owned Magirus since 1975, sold

2000-433: 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 0.6 power of the capacity ratio (the point six to the power rule ). 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

2080-415: The short-run average total cost (SRATC) curve down and to the right. Economies of scale is a concept that may explain patterns in international trade or in the number of firms in a given market. 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

2160-417: The "physical" point of view of the returns to scale. Furthermore, supply contracts entail fixed costs which lead to decreasing average costs if the scale of production increases. This is of important utility in the study of corporate finance . Economies of productive capacity balancing derives from the possibility that a larger scale of production involves a more efficient use of the production capacities of

2240-410: The 6-tonne Magirus 90M6FK. The creation of a completely new cab design was tasked to Renault Centre de Style to submit proposals.The cabin not only had to be modern in design, but also had to be able to be tilted. Initially there was also the idea of building the models of the four participating brands in one factory, but this was abandoned at an early stage. Mock up scale models were utilized during

2320-627: The Club of Four cab in 1975 on the DAF F700 and F900; it was later used on the F500, F1100, F1300, and F1500. DAF merged with Leyland in 1987, and replaced its Club of Four cabs with Leyland cabs. American Mack also used the Club of Four cabin, thanks to their linkup with Renault (who purchased 10 percent of Mack in 1979). These competed in the Class 6 and Class 7 medium-duty weight categories. Built by RVI in France, it

2400-637: The EEC were, at that time, subject to heavy import duties). At first, H/HB-series trucks (up to 26 tonnes) and J-series light trucks (9–13 tonnes) were fitted with the Club of Four cab. Later, the cab was also used on the heavier G series, as well as the lighter JK65/75/85 trucks and the Renault C and S series. This series was briefly sold as "Saviem" trucks in Britain, but changed to Renault badging in September 1979 as part of

2480-727: The HI-SCR system, a "flap" on the exhaust that retains hot gases to quickly bring the system up to temperature, and EcoSwitch and EcoRoll systems. The vehicle is also available in the Natural Power LNG version. The engines are the 4.5-litre four-cylinder Tector 5 diesel and the 6.7-litre six-cylinder Tector 7 diesel, available in seven power levels from 160 to 320 horsepower (119 to 239 kW; 162 to 324 PS), with maximum torque up to 1,100 N⋅m (811 lb⋅ft; 112 kg⋅m).

2560-1279: The Italian manufacturer Iveco since 1991. The EuroCargo occupies a place between the light Daily and the heavy Stralis in Iveco's lineup. The EuroCargo replaced the Zeta model produced in the 1970s. The first generation was designed by IVECO Design Centre (Neu Ulm) led by Leonhard Schmude with help from Giorgetto Giugiaro of Italdesign . The maximum gross weight was 6-15 tons, and for models produced in Langley (in Great Britain) up to 17 tons. Both 4x2 and 4x4 (10 and 14 tons) were available. There were three Iveco engines available, in different power ranges: In addition, 4 types of cabs were available: standard (length 1,535 mm (60.4 in)), extended bed (2,115 mm (83.3 in)), extended bed (1,535 mm (60.4 in)) and double cab. The 6-10 ton versions were equipped with disc brakes on all wheels, hydraulically assisted. The heavier models had rear drum brakes. They used four types of suspension: parabolic leaf springs, semi-elliptical leaf springs, parabolic springs in

2640-511: 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

2720-564: The assumption of free competition to address the study of firms that have their own particular market. 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

2800-431: The auction. They found that auction volume did not correlate with competition, nor with the number of bidders, suggesting that auction volume does not promote additional competition. 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

2880-431: 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

2960-434: 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

3040-508: 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

3120-452: 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

3200-425: 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

3280-447: 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

3360-398: The development of the cab. Two models where chosen which featured the same basic cabin, but one for lighter payload and a second for a higher payload. Changes made to the final production version included the addition of an extra window behind the doors, beams on the front and side and the repositioning of the direction indicators to the corners of the cab. The shape of the front mudguards

3440-473: The driver and six passengers. All 6-10 ton GVW versions are equipped with disc brakes on all wheels, hydraulically assisted. The heavier models have rear drum brakes. The suspensions are the same as those available on the first series. In 2004 and in 2006 there were updates, especially to the Tector 4 and 6 engine range with the adaptation to the requirements of the Euro 4 and Euro 5 emission standards (with SCR ). With

3520-462: 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

3600-434: 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

3680-422: 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

3760-410: 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

3840-518: 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

3920-454: 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

4000-432: 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". Iveco Eurocargo The Iveco EuroCargo is a range of medium-duty trucks produced by

4080-435: 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

4160-604: 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

4240-612: The front and rear airbags (in the lighter models), air suspension (for urban distribution). In October 1997 there were updates, focusing on the cab and the braking system. At the same time, production in Langley ended, closing the plant. Production was now concentrated in Brescia. The second generation of the series, introduced in 2002, was designed by Bertone . It was produced in Brescia in Italy, Sete Lagoas in Brazil (from January 2005 onwards) and in

4320-438: 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

4400-479: 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

4480-419: 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

4560-792: The less powerful engine was introduced in the mid-1980s, called the MS250. For the North American market a bonneted version was also developed. This was called the CS (for "Conventional Styling") and appeared in 1985. As with the cab-over model, a tractor version (CS300T) was made available a little later.

4640-424: 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

4720-661: The narrower F86 front axle and the N10 rear axle. It was introduced in 1977. In 1980 the next iteration appeared, now using the F7 cab atop the F10/F12's chassis. It continued in production until 1986, when it was replaced by the FS10. Volvo's membership of the Club of Four was a major influence on its decision to shift truck manufacturing to Gent , in Belgium (because imports from Volvo's Gothenburg factory to

4800-409: The new grille have what has been described as a "smile" shape. The main innovations of this model concern the internal and external design: there is a dashboard equipped with new controls that can be used while driving, an airbag integrated in the steering wheel, standard electronic devices for driving assistance such as LDWS, EVSC, AEBS, ACC, LED Daytime Running Lights (DRL) lights. The 2015 model adopts

4880-411: 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

4960-475: 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

5040-405: 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

5120-450: 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

5200-569: 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

5280-400: 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

5360-441: 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

5440-426: 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

5520-427: 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

5600-446: 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

5680-449: 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

5760-399: 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

5840-430: The truck as a Magirus or Iveco-Magirus (with slightly changed designations) until they retired the Magirus badge entirely. From then on, Iveco marketed the Club of Four truck - still as the "MK" - directly under their own name. Production came to an end in 1992 as it was replaced by the new Iveco Eurocargo , although limited production of crew cabs for special applications continued a little while longer. DAF started using

5920-502: The update their maximum power was increased by about 10–20 horsepower (7–15 kW; 10–20 PS). Euromidi bus chassis based on the Eurocargo were produced at the Barcelona plant. In mid-2008, the Eurocargo was facelifted. The main changes are visible in the design and styling of the cabin. Iveco replaced all its own transmission models with new versions from the German manufacturer ZF with

6000-417: 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

6080-556: 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

6160-547: Was also changed from angular to round. At first, Volvo used the cab most; adopting it across the F4 (F406/F407/F408) and F6 (F609/F610/F611/F612/F613/F614) ranges of trucks. The first to be sold in the UK was the F7 range of trucks, which replaced Volvo's old F86. These Club of Four cabs continued until 1985-1986 by which time the Volvo FL was being produced with new Volvo cabs, although the new FL6

6240-459: Was merged with Berliet to create Renault Véhicules Industriels (RVI), but the new company continued as a member of the Club. Magirus-Deutz became part of Iveco . The cab was used on a wide range of different trucks. It was even used on Mack trucks in the USA. It remained in production for almost a quarter of a century. Although initially intended for medium trucks it was also used on light trucks, even

6320-551: Was sold as the Mack Mid-Liner or Manager. Originally it was available in MS200 or MS300 models, fitted with 5.5 or 8.8 litre turbocharged diesel inline-six engines respectively. These were built by Renault and offered 175 hp (130 kW) or 210 hp (157 kW). The MS300 was also available as a tractor unit. The Mack Mid-liner range was replaced in 2001 by the new Mack Freedom , also built by Renault. A heavier duty version with

6400-514: Was superficially similar to the Club of Four. Volvo's Club of Four cabs had to be reinforced to meet strict Swedish safety standards, which made their weight less competitive. The Club of Four cab was also used on the CH230, a series of specially built narrow-bodied, larger engined truck to fit Switzerland's restrictive rules on size and weight. The first CH230 used the Club of Four cab atop the F89 chassis, with
