Does academic economic research produce material of general scientific value, or do academic economists write only for peers? Is economics scholarship uniquely insular? We address these questions by quantifying interactions between economics and other disciplines. Changes in the influence of economic scholarship are measured here by the frequency with which other disciplines cite papers in economics journals. We document a clear rise in the extramural influence of economic research, while also showing that economics is increasingly likely to reference other social sciences. A breakdown of extramural citations by economics fields shows broad field influence. Differentiating between theoretical and empirical papers classified using machine learning, we see that much of the rise in economics' extramural influence reflects growth in citations to empirical work. This growth parallels an increase in the share of empirical cites within economics. At the same time, some disciplines that primarily cite economic theory have also recently increased citations of economics scholarship.

内部工作还是影响深远？校外引文与经济奖学金的影响

学术经济学研究会产生具有一般科学价值的材料，还是学术经济学家仅为同行撰写论文？经济学奖学金独特地孤立吗？我们通过量化经济学与其他学科之间的相互作用来解决这些问题。在这里，经济学术影响力的变化是通过其他学科在经济学期刊上引用论文的频率来衡量的。我们记录了经济研究的壁外影响力的明显上升，同时也表明经济学越来越有可能参考其他社会科学。经济学领域对壁外引用的细分显示了广泛的领域影响。区分使用机器学习分类的理论论文和经验论文，我们看到经济学的大部分增长 壁外影响反映了对实证工作的引用增加。这种增长与经济学中经验引用的份额增加平行。同时，一些主要引用经济理论的学科最近也增加了对经济学学术的引用。
