Expanded Measures of Price and Quantity Structures Over Space and Time

该项目的主要重点是提供更新、修订和扩展的宾夕法尼亚世界表(PWT)经济总量数据集，该数据集在二战后整个时期内为150多个国家提供了跨时间和空间的一致数据集，称为宾夕法尼亚世界表。这项持续的努力建立在通过联合国在区域基础上组织的详细基准购买力平价研究的框架之上。为了编制这一大型表格，有必要将最近一个基准年，即1993年的区域基准结合起来，对预计将参加的100多个国家进行世界比较。然后，将把以前的世界比较结果与1993年的基准结合起来，以便为非基准国家的估计值提供基础，并为所有国家的估计值在时间上前后移动提供基础。该项目还包括在PWT本身中增加一些变量，以及包括从基准比较中获得的辅助价格和支出，以便研究人员更容易获得。将向软件提供基准数据，以帮助研究人员在任何一对可能感兴趣的基准国家之间进行比较。还计划制定消费的空间计量，并将其添加到PWT数据集。这一空间消费衡量标准也将在试验性基础上设计，以便在几个地理位置不同的大型国家内提供区域间比较。这些数据的广泛使用，各国对基准研究的广泛参与，以及会议和期刊对国际收入比较的持续关注，表明了PWT对研究界的重要性。

The main focus of this project is to provide an updated, revised and expanded Penn World Table (PWT) data set of economic aggregates that is consistent across time and space for over 150 countries for the whole post World War II period, known as Penn World Table. This continuing effort is built upon the framework of the detailed benchmark purchasing power parity studies organized on a regional basis through the United Nations. To prepare this large Table , it is necessary to combine the regional benchmarks for the latest benchmark year, 1993, into a world comparison for the 100 odd countries that are expected to participate. The results of previous world comparisons will then be integrated with the 1993 benchmark to provide the base for estimating values for non-benchmark countries, and the base for moving estimates of all countries backward and forward in time. This project also includes the addition of some variables in PWT proper, as well as the inclusion of subsidiary price and expenditure from the benchmark comparisons that researchers will be more readily accessible by. Software will be provided with the benchmark data that will help researchers make comparisons between any pair of benchmark countries that may be of interest. It is also planned to develop a spatial measure of consumption and add it to the PWT data set. This spatial consumption measure will also be designed on an experimental basis to provide interarea comparisons within a few large and geographically diverse countries. The wide use of these data,, the extensive country participation in the benchmark studies, and the continued focus on international income comparisons in conferences and journals demonstrate the importance of the PWT to the research community.
