3Weberian 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)
4Weberian Industrial Location Theory
- The best location of production is determined by
minimizing transportation costs, assuming fixed
locations for - Markets
- Raw materials
- Labour
5Raw 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
6Webers 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

12- 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

16In 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?
18Webers 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!

21The Variable Cost Model
- To expand on Webers model and avoid his
preoccupation with transportation costs, we
develop a new model focusing on total costs. -

23Understanding 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
24Imaginary surface
- A locational triangle
- A, B, C represent cheapest source for inputs,
material, labour and power, respectively-. - Lets add isocost lines to point B
25One 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
26Three 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)
27Towards 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.
28Isodapanes 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!
29Isodapanes 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.
30We may now plot a space cost curve as a profile
of the total cost surface
31Price is spatially fixed, hence revenues are
represented as a straight line. Ma and Mb
indicate the spatial margins to profitability

34Point O indicates the minimum cost location!
35Adding 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!
36Classical 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.
