Any plausibly just market exchange must balance two conflicting moral considerations: non-worseness (Wertheimer, 1999) and euvoluntariness (true voluntariness; Munger, 2011). We propose an analytical theory of just market exchange that partly resolves this conflict. Non-worseness implies that all voluntary and mutually beneficial exchanges are morally permissible. The reason is that it cannot be immoral for two negotiators to benefit one another by exchanging, if each has the right to not exchange, and is therefore not obligated to provide a benefit to the other negotiator. Euvoluntariness, on the other hand, elaborates the idea of voluntariness to remedy deficiencies in the standard conception. Voluntariness requires that neither party to a negotiation is coerced into exchange by threat of direct harm, such as physical aggression or the disclosure of embarrassing secrets.1 Euvoluntariness further

公平市场交换理论

任何看似公正的市场交易都必须平衡两个相互冲突的道德考虑：非恶化（Wertheimer，1999）和自然自愿（真正的自愿；芒格，2011）。我们提出了一种公正市场交换的分析理论，可以部分解决这一冲突。非更坏意味着所有自愿和互利的交流在道德上都是允许的。原因是，如果每个谈判者都有权不交换，因此没有义务向另一个谈判者提供利益，那么两个谈判者通过交换相互受益是不道德的。另一方面，Euvoluntariness 阐述了自愿性的想法，以弥补标准概念中的缺陷。自愿性要求谈判的任何一方都不会因直接伤害的威胁而被迫进行交换，
