帕尼尼足球贴纸的经济

     

世界杯的开始仍然是一个星期后，但对于全世界的儿童，帕尼尼2014年巴西贴纸早就开始了。帕尼尼，一家意大利公司，成立于20世纪中叶，于1970年生产世界杯贴纸，今年的版本有640贴纸收集。贴纸的市场不仅仅是孩子们感兴趣,微经济学家也感兴趣。  

当你拥有一个贴纸簿,你就会想要第一个贴纸。 随着贴纸簿的空间逐渐填满,打开包,发现你仍想增加贴纸的数量。 根据Sylvain Sardy和Yvan Velenik,两个日内瓦大学的数学家分析，你将不得不买的贴纸包的数量平均填补这张贴纸簿是899。 假定没有供给冲击市场，这在巴西4月发行的30万张贴纸仍然不能满足需求。
　　 帕尼尼说,每个贴纸打印在相同的面积和随机分布的位置。 在2010年的一篇论文中，Sardy和Velenik扮演了“调节器”的角色，通过检查贴纸在当年瑞士销售的分布。 6000贴纸的样品,他们得出了平均每个贴纸9.09倍。 他们测试了是否这个数字周围的实际波动符合预期的贴纸分布。 这样的统计测试越来越多地应用于在现实市场的现货价格和反竞争行为。

        The beginning of the World Cup is after one week. But for the children all around the world, the Brazil sticker of 2014 has begun earlier. Panini, a Italy corporation, founded in the midst of 20 century, produced the stickers of the world cup in 1970， the edition of this year has collected 640 stickers. The market of the stickers means not only children interested in these stickers，but also microeconomists interested in these stickers.
        When you have a sticker book， you will want the first sticker. With the space of the sticker book is full gradually， you will find you still want to increase the number of stickers. According to the analysis of two mathematicians Sylvain Sardy and Yvan Velenik， you will supplement the number of stickers you have to buy. Suppose you will not provide these stickers to the market， the 300000 stickers still cannot meet the need issued in Brazil in April.
         Panini said, every sticker will print the same area and the area which will be distributed randomly. They get every sticker in the sample of 6000 stickers. They tested the distribution of stickers which is in accordance with the actual fluctuation of this number. The statistical test will be more and more applied to the spot price and anti-competition performance in the actual market.
