MPSC 2023 Prelims Paper-I · Question 34 of 100

Correct — option (4). Alfred Weber's account of industrial location, published in 1909, is a least-cost theory: it holds that a manufacturer will settle at the point where the total cost of production and distribution is lowest, and the whole model is constructed by taking transport cost as the primary determinant and treating everything else as a modification of it. The argument proceeds in two stages, and the order of the stages is what makes transport cost the pivot. Weber first locates the point of minimum transport cost, using the locational triangle whose corners are the sources of the raw materials and the point of consumption. The pull exerted by each corner is proportional to the weight that has to be moved from or to it and to the distance over which it must travel, so the optimum position within the triangle is decided by weights and distances alone. It is at this stage that the material index does its work: where the raw materials are weight-losing, the pull of the source is strong and the plant is drawn to it, since hauling material that will be discarded in manufacture is a waste of freight; where they are pure, the pull is balanced and the plant is comparatively free. Only after this least-transport-cost point has been fixed does Weber admit the other two influences he recognises — the cost of labour and the economies of agglomeration — and he admits them as deviations. A cheaper labour supply elsewhere may justify moving the plant, but only if the wage saving exceeds the extra freight incurred, and Weber supplies the apparatus for testing exactly that: isodapanes, lines joining points of equal additional transport cost, and the critical isodapane, the one along which the added freight precisely cancels the labour saving. A factor that supplies the baseline and the currency in which every other factor must be justified is the pivotal one, and in Weber's scheme that factor is transport cost. Option (4) states it.

• (1)Labour cost plays a pivotal role in the selection of industrial location — Labour cost has a genuine and prominent place in Weber's model, which is why this option is more than a random alternative — but its place is second, not first. Weber treats a cheap labour location as a possible deviation from the least-transport-cost point, and he provides a specific test for whether the deviation is worth making: draw the isodapane on which the additional transport cost equals the labour saving, and move only if the cheap labour site lies inside that critical isodapane. The very structure of that test presupposes that a transport-determined location already exists to deviate from, so labour cost cannot be the pivot of the model; it is measured against transport cost rather than the other way about. A candidate choosing this option has usually remembered that Weber discusses labour and has not registered where in the argument the discussion comes.
• (2)Cost of raw material plays a pivotal role in the selection of industrial location — This option confuses the price of raw material with its weight, and it is the weight that matters in Weber's analysis. The classical model takes raw material prices as given and uniform and asks instead how much material has to be carried and how much of it survives into the finished product — the ratio expressed as the material index. Raw materials therefore influence location in Weber's scheme, but they do so through transport cost rather than alongside it: a gross or weight-losing material generates a heavy freight bill for the portion that will be thrown away, and that bill is what pulls the plant to the source. Reading the option carefully shows why it fails as a statement of the theory. Weber's pivotal variable has to be one that applies to every input and to the output as well, and cost of raw material by itself says nothing about the journey the finished product must make to the market.
• (3)Market accessibility plays a pivotal role in the selection of industrial location — In Weber's model the market is not a variable to be optimised but a fixed point of consumption, one corner of the locational triangle, and its influence enters as the freight cost of carrying the finished product to it. Making market accessibility the pivot describes a different family of theories altogether — the market-area or demand-based tradition associated above all with August Losch, who asked where a firm could capture the largest sales area and so make the greatest profit, and with Walter Christaller's central place theory, which explains the spacing of settlements by the range and threshold of the services they offer. The distinction between the least-cost and the market-area traditions is a standard examination point, and it is worth holding by the question each asks: Weber asks where costs are lowest, Losch asks where revenue is highest.

Industrial location is decided in practice by a long list of considerations — raw materials, power, transport, labour, market, capital, water, land, government policy and the advantages of clustering with other firms — and the value of a location theory is that it imposes an order on that list instead of leaving it as a list. Weber's ordering is the classical one. He assumes a uniform plain with transport costs proportional to weight and distance, fixed points of consumption, labour available in unlimited quantity at fixed wages at fixed places, and raw materials divided into ubiquities that are available everywhere and localised materials that are not. Localised materials are further divided into pure, which pass their whole weight into the product, and gross, which lose weight in manufacture, and the ratio of localised material weight to product weight is the material index. From these assumptions the least-transport-cost point follows geometrically, and Weber represents the cost surface with isotims, lines of equal transport cost for a single commodity, and isodapanes, lines of equal total transport cost. The two secondary factors then enter. Labour may pull a plant away from the transport optimum if the saving exceeds the extra freight, the critical isodapane marking the break-even. Agglomeration may do the same, since firms clustered together share infrastructure, services and a pool of skilled labour, and deglomeration works in the opposite direction when congestion and land prices rise. The model is deliberately simplified, but its central discipline — that any move away from the cheapest transport point must pay for itself — survives the simplifications.

Location theory is a fixed component of the economic geography section, and MPSC asks it as attribution and definition rather than as analysis: who propounded which theory, what a named theory treats as decisive, what a named term means. Weber, Losch, Christaller and von Thunen are the four names that recur, and the efficient way to hold them is by the single question each asks. Weber asks where total cost is least, for a factory. Losch asks where profit is greatest, given the market area a firm can command. Christaller asks why settlements of different sizes are spaced as they are, and answers with the range and threshold of central services. Von Thunen asks how land use arranges itself around a market, and answers with concentric rings ordered by transport cost and perishability. Held that way, an attribution question is answered by matching the question in the stem to the question the theorist asked. This item also repeats a construction used elsewhere in the paper: four options written as complete sentences that are identical except for the factor named, so that the entire question reduces to a single word and no partial credit is available for recognising the theorist's name.

• Alfred Weber's theory of industrial location, published in 1909, is a least-cost theory in which the optimum site is the one with the lowest total cost, and transport cost is the primary determinant from which the analysis begins.
• The least-transport-cost point is found within a locational triangle whose corners are the sources of the localised raw materials and the point of consumption, each corner pulling in proportion to the weight to be moved and the distance involved.
• The material index, the weight of localised raw materials divided by the weight of the finished product, decides whether transport cost draws the plant towards the raw material or leaves it free to approach the market.
• Labour cost and agglomeration economies are secondary in Weber's scheme and may deflect a plant from the transport optimum only if the saving exceeds the added freight; the isodapane and the critical isodapane are the devices used to test this.
• Theories that make the market rather than transport cost the pivot belong to a different tradition, principally August Losch's market-area theory and Walter Christaller's central place theory, while von Thunen's rings explain agricultural land use around a market.

• Naming labour cost as Weber's pivotal factor because the theory discusses it prominently, when it is admitted only as a deviation to be tested against transport cost
• Confusing the price of a raw material with its weight; Weber's raw material influence works through freight, by way of the material index
• Attributing a market-centred explanation to Weber, when the market in his model is a fixed corner of the locational triangle and the market-area tradition belongs to Losch and Christaller
• Answering from the theorist's name alone when all four options are identical sentences differing in a single term, so that only the term is being tested

MPSC asks location theory in a narrow and predictable range of forms: which theorist propounded a named theory, which factor a named theory treats as decisive, what a named technical term means, and which model applies to a described situation. The commission rarely requires the geometry to be worked out, but it does expect the vocabulary — material index, pure and gross raw materials, isotim, isodapane, critical isodapane, range and threshold — to be held precisely, since a single term is often the whole difference between two options. Expect the four classical names of Weber, Losch, Christaller and von Thunen to be shuffled between stems and options, and expect at least one option that states a real feature of the named theory but places it at the wrong level of importance, which is exactly what the labour cost option does here.

• practice — not a real PYQ

  In Alfred Weber's theory of industrial location, a line joining all the points at which the total additional transport cost incurred by moving away from the least-cost location is the same is called which of the following ?

  • (a)An isotim
  • (b)An isodapane
  • (c)An isopleth
  • (d)An isobar

  Answer(b) An isodapane — isodapanes map the total extra freight involved in shifting away from the point of minimum transport cost, and the critical isodapane is the one on which that extra freight exactly equals the saving offered by a cheap labour site. An isotim is the narrower term for a line of equal transport cost for a single commodity, an isopleth is any line of equal value on a map, and an isobar joins places of equal atmospheric pressure.

• practice — not a real PYQ

  The central place theory, which explains the size and spacing of settlements by the range and threshold of the services they provide, was propounded by which of the following ?

  • (a)Alfred Weber
  • (b)Walter Christaller
  • (c)Johann Heinrich von Thunen
  • (d)Ernst Haeckel

  Answer(b) Walter Christaller — his central place theory explains why settlements of different sizes are spaced as they are, using the range of a service and the threshold population it needs to survive. Weber's subject was the least-cost location of a factory, von Thunen's the arrangement of agricultural land use in rings around a market, and Haeckel belongs to biology, having coined the word ecology.
