This paper discusses the issues of the reasonableness of the exchange rate of RMB and the standards that can be used to judge whether RMB should be revalued,and adopt four kinds of newly developed panel unit root tests to examine the purchasing power parity(PPP) of RMB during the period of 1978/1-2004/9.
本文讨论了人民币汇率是否合理、人民币是否应该升值的两个判断标准,采用四种新发展起来的平行数据单位根检验法,对1978年1月—2004年9月的人民币购买力平价进行了检验。
By combining non-parameter Z test method for unit root test of time-series with IPS test method for panel data unit root test, we propose a new non-parameter unit root test method for panel data.
结合时间序列单位根的非参数Z检验方法与平行数据单位根的IPS检验方法,针对横截面内误差项存在L阶自相关关系的平行数据模型提出了非参数单位根检验方法;并利用Monte-Carlo模拟方法比较了这个方法与LL的单位根检验方法。
