摘要
This dissertation centers around the use of a computable general equilibrium (CGE) model adapted to capture regional economic structures and the environmental processes specific to tropical areas. The primary objective is to determine the order of magnitude of the effect on deforestation in the Brazilian Amazon of changes in policy regime and technology, and to identify strategies to lower deforestation rates.
Economic agents enter the model via production decisions, trade, migration, and investment. Relative product prices, factor availability, transportation costs, and available technology are all assumed to influence land use; biophysical processes are assumed to change land cover in concert with changes directly ensuing from decisions made by economic agents.
Agricultural production and other activities are disaggregated by region (Amazon, Center-West, Northeast, Rest of Brazil), by sector, and, by size of operations (smallholder, large farm enterprise). A deforestation sector produces an investment good called "arable land", and is complementary to agricultural production activities.
This study identifies the impact on deforestation and economic development of: (i) changes in the real exchange rate, (ii) a reduction in transportation costs arising from investment in infrastructure in the Amazon, (iii) technological change in Amazon agriculture, (iv) technological change in agriculture outside the Amazon.
First, it is found that after a real exchange rate devaluation, deforestation rates depend substantially on government action. Second, a reduction in transportation costs always leads to an increase in deforestation rates. Third, for technological change in agriculture, the type of factor intensification and relative factor intensities are important determinants of deforestation for agricultural purposes. Furthermore, a striking difference in results between the short run and the long run indicates that inter-regional flows of labor and capital play a crucial role in the expansion of the agricultural frontier. Finally, technological change outside the Amazon can unambiguously reduce deforestation if it occurs in a balanced manner across all agricultural sectors; if the innovation affects a specific factor, the only statement that can be made is that resources will be moved between regions with the "losing" factor ending up on the agricultural frontier.
