上次我们关于跨国价格水平讨论的问题,本质上原来就是一个汇率的问题,前人早有研究,叫做Balassa-Samuelson effect,wikipedia对此词条的解释是:

The Balassa-Samuelson effect is either of two related things:

  1. The observation that consumer price levels in wealthier countries are systematically higher than in poorer ones (the " Penn effect").
  2. An economic model predicting the above, based on the assumption that productivity or productivity growth-rates vary more by country in the traded goods' sectors than in other sectors (the Balassa-Samuelson hypothesis).
