摘要

理性行为模型与其系统偏差(通常被称为“非理性行为”)之间的争论吸引了大量的研究。在这里,我们通过提出对非理性行为的进化解释来调和争论。在一个简单的二元选择模型的背景下,我们证明了非理性行为是随机环境中进化的必要条件。此外,根据环境随机性的程度,种群中存在一个最优的非理性程度。在这个过程中,突变为理性和非理性行为之间提供了重要的联系,从而形成了进化的多样性。我们的研究结果对金融市场、企业行为和金融以外的学科产生了广泛的影响。

Variety Is the Spice of Life: Irrational Behavior as Adaptation to Stochastic Environments
The debate between rational models of behavior and their systematic deviations, often referred to as “irrational behavior”, has attracted an enormous amount of research. Here, we reconcile the debate by proposing an evolutionary explanation for irrational behavior. In the context of a simple binary choice model, we show that irrational behaviors are necessary for evolution in stochastic environments. Furthermore, there is an optimal degree of irrationality in the population depending on the degree of environmental randomness. In this process, mutation provides the important link between rational and irrational behaviors, and hence the variety in evolution. Our results yield widespread implications for financial markets, corporate behavior, and disciplines beyond finance.
