A framework for ex-ante analysis of public investment in forest-based development: An application to the Brazilian Amazon

This paper develops a framework for evaluating the ex-ante economic impacts of public investments in forest-based development. Computable General Equilibrium (CGE) models provide a powerful approach for evaluating public investments in sectors with strong inter-sectoral linkages and for capturing dynamic economy-wide effects. Results of CGE analysis may be analyzed in a social cost-benefit framework typically used by the public sector and multilateral development banks to assess investment viability and trade-offs between alternatives. In this paper, a dynamic CGE is developed to evaluate the impact of a development loan to promote natural forests, forest plantations and agroforestry development in the Amazonian state of Acre, Brazil. Results of the analysis demonstrate the positive impact the expansion forest-based development activities generates and the potential the approach has for comprehensive analysis of the direct, indirect and induced benefits of public forest sector investment.
