很简单,用CIA Worldbook 2007的数据,用GDP based on PPP 除以 Nominal GDP based on exchange rate. 所有数据以美元计价,所以美国的基数是1. 数字越大,表示该国货币越undervalued, 购买力越强。基本规律是,北欧,西欧发达国家排名靠前,亚洲非洲国家偏后,中国是3.83,也就是说用同样的钱在美国可以买到一个单位,而在中国可以买到3.83个单位的货物或服务,即一美元在美国的购买力大约相当于在中国的两个人民币。这个序列和 nominal per capta GDP 几乎是perfectly posotively correlated. 和BigMac Index也基本一致。
当然,篮子里的货物和权重不同,得出的结果也会有一些区别,比如说有人喜欢吃牛排,有人喜欢吃煎饼果子,有人喜欢开宝马,有人喜欢坐地铁,有人喜欢自己割草打扫卫生,有人喜欢雇三个保姆。但这些数字应该是对普通人,对国计民生来说最公正,最精确的估计了。
