我们对 150,000 多条 WallStreetBets 评论进行的分析揭示了当社区成员经历集体兴奋和团结(Collective Effervescence)时的主要短语。利用新颖的词汇赫芬达尔指数(VocaHIn),我们发现 CE 之后股票回报的波动性会增加,反之亦然。
Vocabulary Herfindahl Index (VocaHIn): Linguistic dominance and collective effervescence in WallStreetBets
Our analysis of over 150,000 WallStreetBets comments reveals dominant phrases when members of the community experience collective excitement and solidarity (Collective Effervescence). Using the novel Vocabulary Herfindahl Index (VocaHIn), we find that stock returns volatility increases after CE, and vice versa.
期刊介绍:
Many economists today are concerned by the proliferation of journals and the concomitant labyrinth of research to be conquered in order to reach the specific information they require. To combat this tendency, Economics Letters has been conceived and designed outside the realm of the traditional economics journal. As a Letters Journal, it consists of concise communications (letters) that provide a means of rapid and efficient dissemination of new results, models and methods in all fields of economic research.
