发展经济学如何看待很多发展计划必然导致被迫迁移这一事实的得失 ?本文作者认为 ,“帕累托改进”的核心标准是赋予个人提高当前生活水平的无限权利 ,但其深层含义是防止对富人财产的再分配 ,并将使大多数发展计划永远无法实施 ;而经济学家尽力将这两者加以平衡。通过在评估发展计划中使用分配性加权 ,他们得到的是一种理论上的折中。不过 ,在实践中 ,很少有人在进行计划评估和成本—效益分析时系统使用这样的加权。除了提倡这种做法———它符合经济学界的理论共识———之外 ,本文认为具体的补偿机制和普遍化的安全网将减少保护弱势人群和支持能够产生净收益 (包括弱势人群的收益 )的计划这两者之间的冲突 How does development economics view the pros and cons of the fact that many development plans inevitably lead to forced relocation? According to the author of this article, the core standard of “Pareto Improvement” is to give individuals unlimited rights to improve their current standard of living. However, The redistribution of wealthy assets will make most development plans impossible forever; and economists try their best to balance the two. By using distributive weighting in evaluating development plans, they get a theoretical compromise. However, in practice, few people use this weighting system in planning assessments and cost-benefit analyzes. In addition to advocating this approach - which is in line with the theoretical consensus of economists - this paper argues that specific compensation mechanisms and universal safety nets will reduce the need to protect vulnerable populations and support those that generate net benefits (including those of underprivileged persons ) The conflict between the two plans
