In a recent study, Mejía-Reyes, Díaz-Carreño, and Aroca analyzed the synchronization of the business cycles of the states of Mexico. Using an extended gravitational model, they propose and test a set of variables to explain the co-movement of those cycles. Following on from their work, this paper proposes that one variable in particular, economic complexity, not only explains the synchronization of the business cycles of Mexican states but, in fact, also does a better job at explaining it on its own than the entire set of seven variables proposed by Mejía-Reyes et al. (2019). The paper provides a more parsimonious specification to explain the co-movement of the states’ business cycles by using a single variable that contains information on their relative productive structures.

墨西哥各州商业周期的同步及其与经济复杂性的关系，2000-2014

在最近的一项研究中，Mejía-Reyes、Díaz-Carreño 和 Aroca 分析了墨西哥各州商业周期的同步性。使用扩展的引力模型，他们提出并测试了一组变量来解释这些循环的协同运动。继他们的工作之后，本文提出一个变量，特别是经济复杂性，不仅可以解释墨西哥各州商业周期的同步性，而且事实上，在解释它方面，它本身比整个集合更好Mejía-Reyes 等人提出的七个变量。(2019)。这篇论文提供了一个更简洁的规范，通过使用包含其相对生产结构信息的单一变量来解释各州商业周期的协同运动。
