The Willamette River Case: Costs 233 



wise accrue. But not every other region would participate in 

 financing to the same extent under the two models. Under invest- 

 ment Model B, for example, the Middle Atlantic states would con- 

 tribute about 10 per cent more than they would under the assinnp- 

 tions governing the consumption model, whereas the East North 

 Central states would experience opposite effects. However, since no 

 region other than the one in which the project is centered con- 

 tributes as much as 10 per cent toward meeting the costs, even 

 variations of 10 per cent between the two models for any region 

 do not affect its participation in the total costs by as much as 1 

 per cent. 



Since comments relative to the regional incidence of costs assum- 

 ing nonfederal public or private development, based on the invest- 

 ment tax model, are symmetrical with those made in discussion 

 of the consumption tax model, they will not be repeated here.
