VII. Effect of Distance on the Unit Spatial Cost 



With broiler production density held constant, firms increasing in 

 size must expand their broiler producing areas. Increasing the areas in- 

 creases the average trip distance and the total vinit spatial cost. To illus- 

 trate this relationship, the added or marginal spatial cost was derived 

 for each band at each density level from the cost data in Table 6. These 

 unit costs were paired with the respective one way road mileages from 

 the center to the average broiler production locations in the bands in 

 Table 7 and plotted in Figure 10.
