Expanded Measures of Price and Quantity Structures Over Space and Time

该项目的主要重点是提供一个更新、修订和扩展的宾夕法尼亚世界表（PWT）数据集，该数据集涵盖了二战后整个时期150多个国家的经济总量，跨越时间和空间，被称为宾夕法尼亚世界表。这项持续的努力是根据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进行的。为了编制这一庞大的表格，有必要将最近基准年（1993年）的区域基准合并为预期参加的100多个国家的世界比较。然后，以前的世界比较结果将与1993年的基准结合起来，为估计非基准国家的价值提供基础，并为所有国家的估计数及时前后移动提供基础。本项目还包括在PWT中增加一些变量，以及从基准比较中纳入附属价格和支出，研究人员将更容易获得这些变量。软件将提供基准数据，帮助研究人员对可能感兴趣的任何一对基准国家进行比较。还计划制定消费的空间衡量标准，并将其添加到PWT数据集中。这种空间消费措施也将在实验的基础上设计，以便在几个地理上不同的大国内进行地区间比较。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，都表明了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.
