Solid Wood—Timber Assessment Market Model (TAMM)

  • Darius M. Adams
Part of the Managing Forest Ecosystems book series (MAFE, volume 14)

TAMM simulates behavior in the markets for solid wood products (lumber and wood-based panels) and sawtimber stumpage. TAMM is a spatial equilibrium model 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 to allow exogenous projection of product recovery factors. Capacity change over time is based on an accelerator approach adjusted for expected future returns. Sawtimber-stumpage supply relations derive from intertemporal profit and utility maximization objectives for industrial and nonindustrial private owners, respectively. Equilibrium solutions are found using a “net revenue maximization” approach constrained to meet conditions for a spatial equilibrium. A concluding literature review compares the TAMM structure with other approaches to modeling the solid wood sector.
