摘要

本文应用扩展的Box-Cox模型对九个新欧盟国家的购买力平价(PPP)的功能形式进行了检验。研究发现，除捷克共和国外，八个国家可以拒绝广泛使用的PPP双对数形式，除斯洛文尼亚外，八个国家可以拒绝单一弹性。因此，大多数国家的购买力平价具有非线性函数形式，并表现出非酉弹性。

On the functional form of PPP: the case of nine new EU countries

This article applies the extended Box–Cox model to test functional forms of purchasing power parity (PPP) for nine new EU countries. It finds that the widely used double-log form for PPP can be rejected for eight countries except for the Czech Republic and that the unitary elasticity can be rejected for eight countries except for Slovenia. Hence, most countries have a nonlinear functional form of PPP and exhibit a nonunitary elasticity.
