Abstract

In this paper, we propose a model which simulates odds distributions of pari-mutuel betting system under two hypotheses on the behavior of bettors: 1. The amount of bets increases very rapidly as the deadline for betting comes near. 2. Each bettor bets on a horse which gives the largest expectation value of the benefit. The results can be interpreted as such efficient behaviors do not serve to extinguish the FL bias but even produce stronger FL bias.

Pari-mutuel投注系统中的有效微观行为和FL偏差
在本文中,我们提出了一个模型,该模型在下注者行为的两个假设下模拟了对赌系统的赔率分布:随着投注截止日期的临近,投注金额迅速增加。2. 每个投注者都押注于一匹收益期望值最大的马。结果可以解释为,这种有效的行为不仅不能消除FL偏置,反而会产生更强的FL偏置。
