  • 1. Space and Economics Chapter 3: Classical Location Theory of the Firm Author Wim Heijman (Wageningen, the Netherlands) July 21, 2009
  • 2. 3. Classical location theory of the firm 3.1 Minimization of transportation costs: one final product 3.2 Minimization of transportation costs: one resource, one final product 3.3 Trans shipment costs 3.4 Other location factors 3.5 Alfred Weber’s theory on location of the firm 3.6 The Theory of the market areas 3.7 Spatial elasticity of demand 3.8 Market forms: spatial duopoly 3.9 Application
  • 3. 3.1 Minimization of transportation costs: one final product Location of one ice cream vendor on the beach Customers equally distributed over the beach Customers have equal preferences for ice cream The lower the average distance between ice cream vendor and customers the more ice cream will be sold

  • 9. 3.2 Minimization of transportation costs: one resource, one final product K = ata f a + btb f b t b = 100 − t a , a :1000; b :100; f a = fb = 0.10 K = 0.10 ⋅1000t a + 100 ⋅ (100 − t a ) ⋅ 0.10 = 1000 + 90t a .

  • 11. 3.3 Trans shipment costs * Trans shipment costs are costs that are made when the transportation mode changes. * For example, in a sea port, the cargo may be transported further to the hinterland by truck, rail or inland waterways. * Trans shipment costs are normally expressed in money units per weight unit (e.g. euro’s per ton)
  • 12. 3.3 Trans shipment costs S O G M tg tm T Figure 3.6: Location S of a business with transshipment location O
  • 13. 3.3 Trans shipment costs K = gt g f g + mt m f m + mom + gog , tm = T − t g , K = ( gf g − mf m )t g + mf mT + mog + gom .
  • 14. 3.3 Trans shipment costs In the case of trans shipment costs the optimum location is found with: K g = mf mT + mom , K m = gf gT + gog , K o = ( gf g − mf m )t g + mf mT .
  • 15. 3.3 Trans shipment costs If K g = Km = Ko. Then the firm is footloose
  • 16. 3.4 Other location factors Apart from transportation costs there are two other important location factors: labour costs; agglomeration benefits or external economies of scale.
  • 17. 3.4 Other location factors Agglomeration: a spatial clustering of interacting firms that is mutually beneficial because it generates a decrease in production costs Deglomeration: spatial deconcentration of firms because of external diseconomies of scale

  • 40. 3.8 Market forms: spatial duopoly Hotelling’s Law: spatial competition leads to clustering of competitors in the centre Hotelling’s Law is based on a zero spatial demand elasticity: In terms of game theory Hotelling’s Law describes a Nash Equilibrium α = 0. Hotelling’s Law is also used by political scientists to explain the positioning of candidates running for a political position: http://www.rawstory.com/exclusives/steinberg/ice_cream_08 2005.htm
