墨尔本代写assignment：国际货币经济学
测试PPP假设很重要，因为在当前的国际货币经济学中，它至少作为一种长期关系被隐式或明确地使用。例如，早期的汇率货币模型假设持续的购买力平价，而Dornbusch（1976）最初开发的那种粘性价格汇率模型允许汇率在短期内偏离购买力平价，尽管它被保留为长期均衡条件。尽管如此，购买力平价的长期均衡的存在仍然是一个难题。因此，本研究的目的是为长期PPP假设提供一些进一步的测试。
预计在研究中将实现若干目标：
一世。要全面了解购买力平价的重要性。
II。提供不同的模型来测试长期PPP假设。
III。收集与研究相关的数据。
IV。找出长期PPP假设是否存在的经验证据。
v。比较每个模型以提供更正确的实证结果。

Testing the PPP hypothesis is important since it is used, implicitly or explicitly, at least as a long-run relationship, in much of current international monetary economics. For example, early monetary models of the exchange rate assume continuous purchasing power parity, whilst sticky-price exchange rate models of the kind originally developed by Dornbusch (1976) allow the exchange rate to deviate from purchasing power parity in the short-run, although it is retained as a long-run equilibrium condition. Despite all that, the existence of the long-run equilibrium of purchasing power parity is still a puzzle. So the purpose of this research is to provide some further tests for long run PPP hypothesis.
Several objectives are expected to be achieved in the research:
i. To have a comprehensive understanding the importance about purchasing power parity.
ii. To provide different models to testing the long run PPP hypothesis.
iii. To collect data that is relevant to the research.
iv. To find empirical evidences of whether the long run PPP hypothesis exists.
v. Compared each model to provide a more correct empirical result.
