Do Professionals Get It Right? Limited Attention and Risk‐taking Behaviour
利用1992-2014年世界杯高山滑雪数据,发现专业运动员在处理成绩时间差异时存在左数字偏差,即过度关注最左边数字,导致风险承担行为增加,且高压力或经验无法消除此偏差。
Does information processing affect individual risk‐taking behaviour? This article provides evidence that professional athletes suffer from a left‐digit bias when dealing with signals about differences in performance. Using data from the highly competitive field of World Cup alpine skiing for the period of 1992–2014, we show that athletes misinterpret actual differences in race times by focusing on the leftmost digit, which results in increased risk‐taking behaviour. For the estimation of causal effects, we exploit the fact that tiny time differences can be attributed to random shocks. We find no evidence that high‐stakes situations or individual experience reduce the left‐digit bias.
