This effect began to fall with the Berlin Wal

6、l.除了考虑到运动员在前后两届奥运会中能够持续发挥良好，这些神情懊丧的科学家们煞费苦心地找到了其他两种 具有显著性差异的结果。首先，有这样一种前苏联效应，而 且曾经以方案经济体制为指导的社会主义阵营国家正是凭 借着这样的一种效应才在奥运赛场上表现得特别精彩。有人 猜度揣测，这些社会主义国家强迫那些富有才华的年轻运动 员们专攻竞技角逐，并给他们大量服用类固醇药物。但是这 样的效应随着柏林墙的倒塌也开头日渐步入下风。3 / 6本文格式为 Word 版，下载可编辑Second, the host nation tends to win more medals than it does at any

12、。而那些可以不需要考虑显著性差异的猜测模型只有当加 入第三个变量时才能够成立。但换句话说，这样的变量也起 不了太大的作用。其次，东道主国家好像比以往任何时候都能够赢得更多 的奖牌。不过其中的缘由并不清晰，这就好比经济学家们并 不知道 主场效应详细能发挥多大的作用一样。因此，对他 们来说，猜测出英国今年能够包揽奖牌的数量就相当于赢得 了这项百米冲刺的冠军一样。来自达特茅斯塔克商学院的艾 米莉威廉姆斯，在北京奥运会召开时，带领她的团队以 95%5 / 6本文格式为 Word 版，下载可编辑的精确 率赢得了这块奖牌数量猜测大赛的金牌。她指 出，这次英国以四年前的 47 块为基础，总共将赢得 62 枚

14、ldis Kevin Daly, an economist at Goldman Sachs, who calculates that on average the hostnation of an Olympics wins 54% more medals than usual.

We shall soon find outwhich, if any, of these dismalscientists is on the right track.与之相反的是，普华永道的经济学家们认为英
