| Em substituição às florestas nativas, pela abertura de fronteira agrícola, práticas agropecuárias alternativas foram introduzidas nas propriedades rurais com pinheiro-do-paraná (Araucaria angustifolia (Bert.) O. Kunt). Porém, nos últimos anos, a silvicultura tem promovido o desenvolvimento de atividades ligadas às madeiras de pínus, eucalipto, grevílea e bracatinga frente à exaustão de madeira oriunda de espécies florestais nativas, na geração de recursos no meio rural. Ao mesmo tempo, os instrumentos legais estabelecidos inviabilizam o plantio do pinheiro por buscarem a simples preservação com medidas fiscais exacerbadas. Representando 85 % da estrutura fundiária paranaense, as pequenas propriedades buscam erradicar a espécie pelos prejuízos decorrentes.... |

| Recent efforts to forge a consensus on the role developing countries should play in reducing global greenhouse gas emissions have focused attention on climate friendly technologies (CFTs), most notably those that enhance energy efficiency. In the medium term, the effectiveness of technology-based climate strategies will depend critically on the rates at which CFTs diffuse in developing countries. This paper reviews some of the key findings of the economics research on technology diffusion and assesses the implications for climate policy. The most obvious lessons from this research are that widespread diffusion of CFTs may take decades, and that diffusion rates in developing and industrialized countries are likely to be quite different. In addition, the... |

| Significant environmental benefits are often associated with the rapid diffusion of new energy-saving technologies. Over the past decade, the federal government, as well as electric and gas utilities, have begun to provide free technical information to potential buyers to stimulate private investment in certain technologies, particularly for retrofitting existing buildings. Yet it has not been demonstrated that this provision of technical information can truly accelerate the rate of technology diffusion. This study develops a model of firm behavior that incorporates multiple factors in the decision to retrofit high efficiency lighting technologies. Technology retrofit and the acceptance of technical information are modeled as jointly determined dichotomous... |
