本文介紹了 Barberis and Thaler (2003) 提出的行為金融學知識框架。它對於我們學習該領域非常有幫助。此外,在很多 empirical asset pricing 的文章中,學者們都會從風險和行為的角度來解釋提出的異象。從這個角度來說,掌握心理學和有限套利這兩大支柱對於理解很多學術文獻也十分有益。
最後,我的好友徐楊曾在《諾獎得主塞勒教授的行為金融學研究框架 - 有這篇論文就夠了》一文中對 Barberis and Thaler (2003) 進行了解讀。他詼諧的文風比本文更加生動活潑,此外也加入了不同的思考和數據,感興趣的小夥伴不妨一讀。
2013 年,諾貝爾經濟學獎同時頒發給了對市場有效性持完全對立立場的 Eugene Fama 和 Robert Shiller(另外一位是提出 GMM 的 Lars Peter Hansen)。Fama 和 Shiller 的同時獲獎頗具「諷刺意味」。在頒發諾貝爾獎時,瑞典皇家科學院指出,這三位學者的發現表明「市場價格的波動受到理性和人性行為共同影響」。這是人們在探究市場真相道路上堅實的一步,也是行為金融學發展歷程中的重要裡程碑。
