Sawlog Pricing 



In considering the usefulness of j)rice projections, the relation of 

 one price schedule to another price schedule (sawlogs prices vs. pulp- 

 wood prices and harvest cut prices vs. thinning cut prices) is more im- 

 portant tlian the absolute values of any and all price schedule*. To date 

 sawlog prices have lieen higher than pulpwood prices for equal volumes 

 (5) and harvest prices have been higher than thinning prices for equal 

 volumes. These relations hold in the current year and are expected to 

 hold in future years, therefore such price relations are an as iimption 

 of this analysis. Costs are related to returns in a somewhat similar man-
