TiMBA - Timber market model for policy-based analysis: Documentation of model structure, data, and parameters

This working paper details the underlying structure of the Timber market Model for policy-Based Analysis - TiMBA - as well as the data and parameters used for modeling. TiMBA is a partial economic equilibrium model for the global forest sector. The market equilibrium is subject to market clearance and constraints, balancing raw materials, product manufacturing, and consumption while limiting international trade (Paul A. Samuelson 1952). The model structure distinguishes three types of roundwood (fuelwood, coniferous and non-coniferous industrial roundwood), two additional raw products for paper production (other fiber pulp and waste paper), two intermediate products (mechanical and chemical wood pulp) and eight finished products (coniferous and non-coniferous sawnwood, veneer sheets and plywood, particle board, fibreboard, newsprint, printing and writing paper, and other paper and paperboard). Except for sawnwood, intermediate and end products are produced from a mix of coniferous and non-coniferous industrial roundwood.(...)
