A circular economy (CE) would reduce both extraction and disposal by encouraging green design and circular business models, as well as repair, reuse, remanufacturing, and recycling. The CE started among architects and engineers, with little interest among economists. This article introduces CE concepts to economists, introduces key insights about the CE from other disciplines, and describes how economists can use these insights for a more complete economic analysis of policies that can better improve human welfare. An economic model of CE behavior can benefit from understanding the environmental gains from green designs based on engineering,transaction-cost savings from information based on blockchain technology, life cycle assessments based on industrial ecology, and behavioral science concepts of cultural barriers and social decision making that affect how producers and consumers respond to incentives. With various disciplines brought to bear on the subject, the combined analysis can exceed the sum of its parts.

向经济学家介绍循环经济

循环经济（CE）将通过鼓励绿色设计和循环商业模式以及修复、再利用、再制造和回收来减少提取和处置。 CE 最初是在建筑师和工程师中兴起的，但经济学家对此兴趣不大。本文向经济学家介绍了 CE 概念，介绍了其他学科关于 CE 的重要见解，并描述了经济学家如何利用这些见解对能够更好地改善人类福利的政策进行更完整的经济分析。 CE行为的经济模型可以受益于理解基于工程的绿色设计的环境收益、基于区块链技术的信息节省的交易成本、基于工业生态学的生命周期评估以及文化障碍和社会决策的行为科学概念影响生产者和消费者对激励措施的反应。通过对这个主题进行不同学科的研究，综合分析可以超过各个部分的总和。
