Biofuels may make a substantial contribution to meeting the world’s energy needs. That contribution may come sooner and be greater if there is a strong climate policy to reduce greenhouse gases and biofuels can be produced in a way that minimizes greenhouse gas emissions. We investigate the land use implications of biofuels under different policy conditions using a computable general equilibrium model of the world economy that has been adapted to explicitly consider land use change. We find that to meet a substantial portion of the worlds liquid fuel needs a global area approximately equal to that of today’s cropland would be needed. As much as two-thirds of the land could come from intensification of existing land, especially pastureland. Conversion of... |

Este trabalho procura determinar os impactos de diferentes opções de política comercial, sob pressuposições alternativas de retornos à escala e natureza da competição, nos segmentos industriais, com ênfase especial nas indústrias ligadas ao agronegócio. O modelo de equilíbrio geral aplicado, GTAPinGAMS, é usado para implementar as simulações. Os resultados sugerem que os ganhos de bem-estar tenham sido superiores no modelo que considera as imperfeições de mercado. As variações setoriais na produção, importações e exportações foram levemente diferentes em magnitudes e sinais, sob pressuposições alternativas de estruturas de mercados, e dependentes da política comercial implementada. As diferentes medidas de política comercial permitem o aproveitamento de... |

The objective of this paper is to evaluate the impact of government spending with the Interest Rates Equalization (IRE) policy on the economic growth of Brazilian regions. Additionally, it aims to measure the opportunity cost of the subsidy in relation to an alternative application in the transportation sector. The model, database, and software from the General Equilibrium Analysis Project of the Brazilian Economy (PAEG) are applied to the simulations. The result shows that the IRE policy provides economic growth in the Midwestern, Northeastern and Southern regions above the cost of the policy. Besides, in the Northern and Southeastern regions, there is a decrease in the GDP. For Brazil, the policy is cost-effective and offers a 34% rate of return.... |
