Measurement of ownership effects on forest productivity in North Carolina from 1974 to 1984.

A method is presented for analyzing an aggregate forest production function using the North Carolina forestry sector as a case study. A nonlinear Cobb-Douglas function that incorporates biological ownership, and forest-type variables is used to model production. Results show greater stability in the function over time for the inventory measure as opposed to the growth measure. Inferences regarding productivity effects from ownership and forest type changes are also developed. For the inventory measure, forest type more significantly influences the measure than does ownership. For the growth measure, however, both ownership and forest type significantly influence productivity. -Authors
