Reliability of purchasing power parities from the World Bank

该项目旨在提供一个计量经济学框架，以估计购买力平价，并提供一种方法，计算与世界银行国际比较方案购买力平价有关的标准误差。比较方案定期汇编和公布货币购买力平价和真实的收入估计数。这些结果用于研究全球不平等和贫困;宏观经济分析;人类发展指数;和跨国生产力比较。但是，没有关于比较方案购买力平价可靠性的估计数。这一项目的结果可能会提高广泛使用的数据集的质量，包括宾夕法尼亚大学世界表和昆士兰州大学与银行业有关的国际比较数据库。

This project aims to provide an econometric framework to estimate purchasing power parities (PPPs) and a method to compute standard errors associated with the World Bank’s International Comparison Programme (ICP)’s PPPs. The ICP regularly compiles and publishes estimates of PPPs of currencies and real incomes. These results are used for study of global inequality and poverty; macroeconomic analysis; the Human Development Index; and cross-country productivity comparisons. However, no estimates of ICP PPPs’ reliability are available. Results from this project are likely to improve the quality of widely used data sets including the Penn World Tables and the University of Queensland International Comparison Database relevant to banking.
