The Optimal Denomination of Currency
讨论货币面额的最优设计，指出三倍递增原则虽被提出但未被采用，认为现有体系是历史和社会因素演化的结果。
L. G. Telser (1995) and Scott Sumner (1993) argue that the optimal system of denominations of currency would consist of a sequence of denominations that differed from each other by a factor of three. The fact is that today no currency follows the powers-of-three principle. The author argues that existing currency systems are the result of an evolution over time that is subject to historical influences and social factors, especially the counting systems that societies use.
