ABSTRACT

Interdisciplinarity in behavioral economics (BE) has often been described as limited or decreasing since the 1980s. In this article, we investigate the interdisciplinary influences of behavioral economists using quantitative techniques. We find that following an intense period of interdisciplinary exchange among a handful of individuals, interdisciplinarity between economics and psychology has decreased in BE since the 1980s. However, this decreasing interdisciplinarity in BE has been compensated for by the rise of BE in the wider field of economics. While individual BE articles have become less intensely related to psychology, the growing number of BE articles in economics as a whole has intensified the overall interdisciplinarity between economics and psychology. Moreover, the decreasing interdisciplinarity between economics and psychology in BE has not resulted in a return to a self-sufficient economic approach. Instead, we observe a rise in the importance of management studies, as well as a variety of other disciplines in the social and natural sciences, as behavioral economists have diversified their interdisciplinary relationships since the 2000s. Finally, the level of interdisciplinarity between economics and psychology in behavioral economics remains higher than the average economics' article, making the specialty distinctively interdisciplinary.

摘要

自 1980 年代以来，行为经济学 (BE) 的跨学科性经常被描述为有限或减少。在本文中，我们使用定量技术调查行为经济学家的跨学科影响。我们发现，在少数人之间进行了一段激烈的跨学科交流之后，自 1980 年代以来，经济学和心理学之间的跨学科性在 BE 中有所减少。然而，BE 在更广泛的经济学领域的兴起弥补了 BE 跨学科性的下降。虽然个别 BE 文章与心理学的相关性已变得不那么密切，但整个经济学中越来越多的 BE 文章加强了经济学和心理学之间的整体跨学科性。而且，BE 中经济学和心理学之间的交叉学科日益减少并没有导致回归自给自足的经济方法。相反，我们观察到管理研究以及社会和自然科学中的各种其他学科的重要性在上升，因为行为经济学家自 2000 年代以来已经多样化了他们的跨学科关系。最后，行为经济学中经济学和心理学的交叉学科水平仍然高于经济学的平均水平，使该专业具有鲜明的交叉学科特色。自 2000 年代以来，行为经济学家已经多样化了他们的跨学科关系。最后，行为经济学中经济学和心理学的交叉学科水平仍然高于经济学的平均水平，使该专业具有鲜明的交叉学科特色。自 2000 年代以来，行为经济学家已经多样化了他们的跨学科关系。最后，行为经济学中经济学和心理学的交叉学科水平仍然高于经济学的平均水平，使该专业具有鲜明的交叉学科特色。
