| Voluntary opt-in programs to reduce emissions in unregulated sectors or countries have spurred considerable discussion. Since any regulator will make errors in predicting baselines and participants will self-select into the program, adverse selection will reduce efficiency and possibly environmental integrity. In contrast, pure subsidies lead to full participation but require large financial transfers. We present a simple model to analyze this trade-off between adverse selection and infra-marginal transfers. We find that increasing the scale of voluntary programs both improves efficiency and reduces transfers. We show that discounting (paying less than full value for offsets) is inefficient and cannot be used to reduce the fraction of offsets that are... |

| Reducing Emissions from Deforestation and Forest Degradation (REDD+) is an important topic in the debate on policies to mitigate climate change. This is the first study to test and compare the environmental impact of different REDD+ payment schemes in the field, and provide some insights on the effectiveness of different policies with respect to the permanence of forest-based emission reductions. This study implements a stated preference experiment of time allocation in the unique setting of the Kasigau Corridor REDD+ Project in Kenya, where charcoaling is a major source of forest degradation. The impact on time allocation is analyzed under the presumption that a hypothetical agricultural policy or an eco-charcoaling policy was introduced. We find that a... |

| O objetivo deste trabalho foi ajustar modelos para estimar características dendrométricas da Caatinga brasileira a partir de dados do sensor TM do Landsat 5. Medidas de diâmetro e altura das árvores foram obtidas de 60 parcelas de inventário (400 m2), em dois municípios do Estado de Sergipe. A área basal e o volume de madeira foram estimados com uso de equação alométrica e de fator de forma (f = 0,9). As variáveis explicativas foram obtidas do sensor TM, após correção radiométrica e geométrica, tendo-se considerado, na análise, seis bandas espectrais, com resolução espacial de 30 m, além dos índices de razão simples (SR), de vegetação por diferença normalizada (NDVI) e de vegetação ajustado ao solo (Savi). Na escolha das melhores variáveis explicativas,... |

| Contemporary conservation interventions must balance potential trade-offs between multiple ecosystem services. In tropical forests, much attention has focused on the extent to which carbon-based conservation provided by REDD+ policies can also mitigate biodiversity conservation. In the nearly one-third of tropical forests that are community owned or managed, conservation strategies must also balance the multiple uses of forest products that support local livelihoods. Although much discussion has focused on policy options, little empirical evidence exists to evaluate the potential for trade-offs among different tropical forest value components. We assessed multiple components of forest value, including tree diversity, carbon stocks, and both timber and... |
