Tempus Fugit: Time Pressure in Risky Decisions
通过两个实验研究时间压力对风险决策的影响，发现时间压力不影响对收益的风险态度，但增加对损失的风险厌恶，并在混合前景中同时增强损失厌恶和收益寻求，取决于前景的框架。
We study the effects of time pressure on risky decisions for pure gain prospects, pure loss prospects, and mixed prospects involving both gains and losses. In two experiments we find that time pressure has no effect on risk attitudes for gains, but increases risk aversion for losses. For mixed prospects, subjects become simultaneously more loss averse and more gain seeking under time pressure, depending on the framing of the prospects. The results suggest the importance of aspiration levels, and thus the overall probability to break even, under time pressure. We discuss the implications of our findings for decision-making situations that involve time pressure. This paper was accepted by Uri Gneezy, behavioral economics.
