Since Cassel (1922) proposed the theory of Purchasing Power Parity, only after 60 years until the 20th century, the rigorous empirical evidence appeared to prove that PPP holds over a long period of time (Friedman and Schwartz, 1963, Gaillot, 1970). Balassa (1964) and Samuelson (1964) proposed theory of productivity bias hypothesis provides support to the PPP too, and it had a tremendous impact. During the next 30 years, PPP was one of the most discussed topics in economics but the results of these discussions varied greatly. This result not only led to the renewal and progress of the quantitative methods used to test the purchasing power parity condition, but also promoted the growing purchasing power parity theory. Before the 1970s, the empirical studies of PPP used the simple OLS regression only. In the 1980s, the mainstream empirical research methods included the two-phase EG method, the ADF test, variance ratio, Fractional Integration approach, etc. After a detailed study on the bilateral floating exchange rate data using the data from industrialized countries after 1973, economists such as Dardy (1983), Frankel (1986), Meese and Rogoff (1988) arrived at a basic conclusion: the exchange rate is a random walk process, and the purchasing power parity does not hold.

因为卡塞尔(1922)提出的购买力平价理论,仅过了60年,直到第二十世纪,严谨的实证证据似乎证明PPP持有超过一段很长的时间(弗里德曼和施瓦兹,1963,Gaillot,1970)。巴拉萨(1964)和萨缪尔森(1964)提出的理论的生产力偏差假说对PPP还提供了支持,并产生了巨大的影响。在接下来的30年中,PPP是一个热点经济学但这些讨论的结果差别很大。这一结果不仅导致和用于测试的购买力平价条件的定量方法研究进展的更新,也促进了增长的购买力平价理论。在20世纪70年代以前,购买力平价的实证研究,用简单的OLS回归只。在上世纪80年代,主流的实证研究方法包括两相EG方法,ADF检验,方差比,分数次积分的方法,使用数据等发达国家经过1973双边浮动汇率数据进行了详细的研究,如dardy经济学家弗兰克尔(1983),(1986),她和罗戈夫(1988)到达一个基本结论:汇率是一个随机游走过程,和购买力平价不成立。
