祖尼诺等。在金融文献中使用创新的统计工具: 复杂性-熵因果关系平面。这种笛卡尔式表示建立了不同市场的效率排名,并区分了不同的债券市场动态。此外,从复杂熵因果关系平面导出的分类结果与主权证券评级公司对主权证券的评级结果一致。由 Bariviera 等人开发的一个类似的研究。以美国石油和能源公司债券为样本,运用复杂熵因果关系平面,探讨了信用评级与信息效率的关系。他们发现,这一分类与穆迪给予的信用评级相一致。

The concept of economic complexity index, introduced by the MIT physicist Cesar A. Hidalgo and the Harvard economist Ricardo Hausmann and made available at MIT's Observatory of Economic Complexity, has been devised as a predictive tool for economic growth. According to the estimates of Hausmann and Hidalgo, the ECI is far more accurate in predicting GDP growth than the traditional governance measures of the World Bank.

经济复杂性指数的概念,由麻省理工学院的物理学家 Cesar a. Hidalgo 和哈佛大学的经济学家 Ricardo Hausmann 提出,并在麻省理工学院的经济复杂性观察站提供,已经被设计成经济增长的预测工具。根据 Hausmann 和 Hidalgo 的估计,与世界银行的传统治理措施相比,出口信贷保险在预测 GDP 增长方面要准确得多。

在金融理论和扩散理论之间也有相似之处。例如,期权定价的布莱克-斯科尔斯方程是一个扩散-对流方程(见对布莱克-斯科尔斯方法论的批判)。布莱克-斯科尔斯理论可以扩展为经济活动中主要因素的分析理论。其他经济学家,包括毛罗 · 加勒盖蒂,史蒂夫 · 基恩,保罗 · 奥默罗德和艾伦 · 基尔曼对此表现出了更多的兴趣,但也批评了经济物理学的一些趋势。最近,实验经济学创始人之一、诺贝尔经济学奖得主弗农 · l · 史密斯使用了这些技术,并声称它们显示了很大的希望。在各种经济数据中也发现了一些标度律。
