Mitigating Climate Change by Planting Trees: The Transaction Costs Trap
研究加拿大通过植树固碳缓解气候变化的成本问题，发现说服农民将农地转为林地的交易成本很高，可能使造林成本超出传统经济分析的预期。
<i>Land-use change and forestry projects are considered a low-cost option for addressing climate change mitigation. In Canada, afforestation is targeted to sequester enough carbon to meet one-fifth of its international obligations, and at lower cost than emissions reduction. We examine economic aspects of the institutions and incentives needed to encourage landowners in Canada to adopt tree planting on a large scale. Based on data from a survey of landowners, the transaction costs of getting landowners to convert their land from agriculture to plantation forests appear to be a significant obstacle, possibly increasing the costs of afforestation projects beyond what conventional economic analysis suggests.</i>
