Title: Classical Location Theory


1
Classical Location Theory
  • Based on Alfred Weber, Über den Standort der
    Industrien 1909

Weberian Location Theory
  • A deductive and normative theory to explain
    industrial location
  • Normative theory to explain where industrial
    activity should be located
  • The question of the best location is far more
    dignified than determination of the actual one
    (August Losch, The Economics of Location 1954)

4
Weberian Industrial Location Theory
  • The best location of production is determined by
    minimizing transportation costs, assuming fixed
    locations for
  • Markets
  • Raw materials
  • Labour

5
Raw Materials and Webers Material Index
  • Ubiquitous raw materials
  • Localized raw materials
  • Pure
  • Gross
  • If MI gt 1, raw material orientation
  • If MI lt 1, market orientation

6
Webers Assumptions
  • Perfect competition each producer supplies a
    market of unlimited size with no possibility of
    monopolistic advantages arising from the chosen
    location
  • Fixed locations for raw materials, labour and
    markets
  • Isotropic surface

7
  • One localized pure raw material
  • Located at RM site
  • RM procurement cost increases away from raw
    material site

8
  • But FP distribution cost decreases away from raw
    material site and reaches a minimum at the market
    itself.

9
  • With a pure raw material and a constant freight
    rate, total transportation costs are constant.
  • Thus we should be indifferent about industrial
    location, costs are same everywhere.

10
  • One localized pure raw material plus ubiquities
  • Ubiquities add to the weight of the FP
  • But they are as available at the market as
    everywhere else.
  • Market oriented industrial location

  • One localized gross raw material
  • Location at RM site eliminates cost of
    transporting waste materials
  • Processing of gross raw materials tends to be
    oriented to raw material locations

In the real world
  • Freight rates for finished products are higher
    than for raw materials.
  • Terminal costs act as a fixed cost discouraging
    industrial location at intermediate locations.
  • But intermodal transfers may require a
    break-in-bulk which may favour an intermediate
    location feasible.
  • Freights are stepped by zones rather than a
    smooth function of distance

17
  • So this kind of Weberian analysis is only the
    beginning of a much more complex situation.
  • And it assumes only one raw material is required!
  • What if there is more than one input to an
    industrial process?

18
Webers Varignon frame
  • A mechanical solution
  • Imagine a board with holes located at their
    relative locations. Tie strings together and
    thread through the holes. From each string we
    suspend weights proportional to the quantity of
    localized raw materials required for the product.
  • Mathematical solutions are also possible!

21
The Variable Cost Model
  • To expand on Webers model and avoid his
    preoccupation with transportation costs, we
    develop a new model focusing on total costs.
  • Based on David Smiths Industrial Location 2nd
    ed. New York John Wiley 1981

22
Imaginary data
Based on David Smiths Industrial Location 2nd
ed. New York John Wiley 1981
23
Understanding the data
  • Basic cost is for the required quantity to
    produce one unit of output at its cheapest
    source.
  • It will cost an additional 3.33 cents per mile to
    move each of the raw material, power and labour
    inputs away from their minimum cost locations.
  • Land marketing are treated as ubiquities or
    spatial constants.
  • This may be shown graphically

24
Imaginary surface
  • A locational triangle
  • A, B, C represent cheapest source for inputs,
    material, labour and power, respectively-.
  • Lets add isocost lines to point B

25
One supply funnel centred on B
  • Basic cost at point B is 30.
  • Beyond B, the locational cost includes
    transportation, increasing at a fixed rate away
    from B creating a supply funnel

26
Three supply funnels
  • Add isocost lines to points A and C
  • Note that locational pull is the same for all
    three inputs
  • These isocost lines are known as isotims, they
    rise away from points A,B,and C (note that the
    direction of slope is indicated by the
    orientation of isotim labels)

27
Towards a total cost surface
  • We may plot the total cost (basic cost
    locational cost) for any point.
  • If we do this for every point in space, we create
    a total cost surface.
  • We could then show the shape of this three
    dimensional surface with a family of isocost
    lines which are known as.

28
Isodapanes I
  • A line joining equal total cost locations drawn
    around the minimum total cost location
  • Note that as a specific form of generic isolines,
    these isodapane labels are upside down!

29
Isodapanes II
  • To give a two dimensional impression of this
    three dimensional cost surface,
  • we may draw a profile along line PQ
  • We may then project a line downwards from each
    point of intersection between an isodapane and
    line PQ.

30
We may now plot a space cost curve as a profile
of the total cost surface
31
Price is spatially fixed, hence revenues are
represented as a straight line. Ma and Mb
indicate the spatial margins to profitability

35
Adding Complexity to the Model
  • Allow basic costs to vary
  • Allow locational costs to vary
  • A new family of isodapanes is created which
    yields,
  • a new space-cost curve!

36
Classical Location Theory
  • Data needs are huge
  • Cost, revenue and profit surface for each
    industry is complex and different
  • Some industries have a flat profit topography,
    others are more rugged, and still more face
    mountain and canyon-like features.
  • But classical theory pays little heed to
    strategic behaviour by multilocational firms.
