The rate of technological progress in the lumber and wood-products industry was estimated by a method Solow introduced in 1957. An aggregate production function was specified using value-added as the measure of output, man-years as the labor input, and the book value of fixed and working capital as the other input. Technological progress was the residual value in output after accounting for the influence of the labor and capital inputs. The predominant source of growth in real output per employee was growth in real factor input, specifically an increase in capital intensity, rather than in total factor productivity. Nevertheless, technology was found to be advancing at an average rate of 1.75 percent per year between 1949 and 1970. Forest Sci. 21:149-154.
