Abstract

Lotto players often choose numbers non-randomly, a behavior known as conscious selection. In many Western countries, the number 7 is considered lucky, causing it to be disproportionately selected in lotto games. This study quantifies the financial cost of this tendency using data from lotto games in Belgium (2011–2025) and France (2002–2008, 2019–2025), as well as Euromillions data (2016–2025). Due to the parimutuel payout system, tickets containing the number 7 earn significantly lower prizes than those without it. We find that this cost persists across different game formats and time periods.

昂贵的7号

乐透玩家经常非随机选择数字，这种行为被称为有意识选择。在许多西方国家，数字7被认为是幸运的，因此它在乐透游戏中被不成比例地选中。本研究使用比利时（2011-2025年）和法国（2002-2008年，2019-2025年）的乐透游戏数据以及Euromillions数据（2016-2025年）量化了这一趋势的财务成本。由于中奖奖金制度，含有数字7的彩票的奖金明显低于没有数字7的彩票。我们发现这种成本存在于不同的游戏形式和时间段中。

期刊介绍： Many economists today are concerned by the proliferation of journals and the concomitant labyrinth of research to be conquered in order to reach the specific information they require. To combat this tendency, Economics Letters has been conceived and designed outside the realm of the traditional economics journal. As a Letters Journal, it consists of concise communications (letters) that provide a means of rapid and efficient dissemination of new results, models and methods in all fields of economic research.
