Sustainability as Opportunity
探讨可持续性概念与契约主义分配公平原则的关系，提出通过向未来世代提供特定资本、技术、资源和环境禀赋来维持生活机会，并强调资本资源替代需有证据表明惠及当代和未来。
This paper explores the relationship between sustainability concepts and contractarian principles of distributional fairness. A commitment to equality of opportunity between contemporaries entails that life opportunities should be nondiminishing from generation to generation. Defining sustainability as nondeclining utility is analytically suggestive but practically problematic given the uncertainties that surround future preferences and technologies. Life opportunities may be sustained, however, by providing future generations with specific endowments of reproduced capital, technological capacity, natural resources, and environmental quality. In this setting, capital-resource substitutions are defensible only if there is compelling evidence that they would benefit both present and future generations.
