Solid Wood—Timber Assessment Market Model (TAMM)del that projects market solutions one period at a time. Product demand is disaggregated into numerous end-use categories and recognizes contemporaneous price-based substitution between different classes of solid wood products. Product supply is derived from a restricted production function form toseparate 发表于 2025-3-27 16:26:33

Base Case Projectionovides one view of future changes in the forest sector and a partial basis for identifying emerging trends that might influence future forest management or forest products production. It envisions continued strong growth in total US forest products requirements (domestic consumption plus exports) to
