主要結論:

只要資訊頻率降低, 即可讓投資風險資產意願提高.

主要實驗設計:

在於資訊迴饋頻率 frequent/infrequent, 其 treatment 有三種:

H: 投資期間1期, 資訊迴饋頻率每1期
M: 投資期間3期, 資訊迴饋頻率每1期
L: 投資期間3期, 資訊迴饋頻率每3期

Bellemare et al. (2005) 實驗結果是: 投資額度 L~M>H

Results

  • We confirm the works by Gneezy and Potters (1997) and others building on it, and furthermore find that experimentally induced myopia in combination with loss aversion remained to affect investment behavior systematically even when flexibility in adjusting investment was no longer varied. MLA is driven by information feedback.

Abstract

We experimentally disentangle the effect of information feedback from the effect of investment flexibility on the investment behavior of a myopically loss averse investor. Our findings show that varying the information condition alone suffices to induce behavior that is in line with the hypothesis of Myopic Loss Aversion.
