Abstract

The literature on lottery gambling shows that players do not select numbers randomly, a phenomenon which is called conscious selection. Mainly, players prefer "small" numbers (less than thirty), either because of the existence of small lucky numbers or because they are victims of the so-called birthday-number effect. Because lotto games are parimutuel, such preferences result in poor ticket choices in terms of achieving below average returns. Using data from Belgium, where approximately 10% of the population plays lotto games every week, this paper extends prior literature by documenting the existence of a gender gap in the birthday-number effect, with women displaying a stronger birthday-number effect than men, as well as the non-persistence of the birthday-number effect (and consecutively of the gender gap) when participants are asked to fill in a second lotto ticket immediately after their first one. The disappearance of the birthday-number effect in sequential choices appears to be driven by response speed, with participants being twice as fast to fill in the second ticket compared to the first one. Moreover, we find that participants who bet on their birthday numbers take significantly more time to complete their ticket. Contrary to prior research, we find that the strength of the birthday-number effect is positively related to deliberative number choices, not intuitive and automatic number choices. Our results are robust to controlling for potential confounding effects including those related to participants' age, education, self-esteem, and superstitious beliefs.

生日数字效应是否存在性别差异?乐透玩家的案例和顺序选择的作用》。
有关彩票赌博的文献表明,彩民并不是随机选择号码的,这种现象被称为有意识选择。彩民主要偏好 "小 "号码(小于 30),这可能是因为存在小的幸运号码,也可能是因为他们是所谓的生日号码效应的受害者。由于乐透游戏是对赌游戏,这种偏好会导致彩票选择不佳,无法获得低于平均水平的收益。比利时每周约有 10%的人口玩乐透游戏,本文利用比利时的数据,通过记录生日数字效应中存在的性别差距(女性比男性表现出更强的生日数字效应),以及当参与者在第一张乐透票之后立即填写第二张乐透票时,生日数字效应(以及连续的性别差距)的不存在,对之前的文献进行了扩展。生日号码效应在顺序选择中的消失似乎是由反应速度驱动的,参与者填写第二张彩票的速度是填写第一张彩票的两倍。此外,我们还发现,投注生日数字的参与者填写彩票的时间明显更长。与之前的研究相反,我们发现生日号码效应的强度与深思熟虑的号码选择呈正相关,而与直觉和自动号码选择无关。我们的结果在控制潜在的混杂效应(包括与参与者的年龄、教育程度、自尊和迷信信仰相关的效应)后是稳健的。
