This award funds the Penn World Table (PWT). This is a data resource for making international comparisons of economic performance (income, output, and production) across countries. The data have been widely used both as a dependent variable to be explained (studies of the determinants of economic performance) and as a control variable included in other studies as a way to control for differences across countries in economic resources.The PWT continues to be updated on a regular basis to take into account changes in economic performance. In addition to requesting support for these updates, the PIs want to improve the methods used to make the international comparisons. The PWT has relied in part on a comparison program conducted by the UN and the World Bank. That comparison has focused on the expenditure side of national accounts (what a country consumes, invests, spends on government activities, exports, and imports). An alternative way to compare economies is to consider the production side of national accounts. The PWT team is collaborating with a leading European research group to incorporate these production comparisons into the PWT. They develop separate estimates of production and income that are comparable across countries, and use several different analytic approaches in order to appraise which approach is most effective for future maintenance of the PWT.They also develop improved models of the relationship between implicit growth rates implied by their comparisons to national growth rates calculated through national income accounts. The question is how to use economic theory and empirical methods to best account for economic growth when both economic structures and relative prices are changing over time.The Penn World Tables are widely used by researchers, policymakers, and students who are interested in international economic comparisons.

该奖项资助了宾大世界表（PWT）。这是对各国经济表现（收入、产出和生产）进行国际比较的数据资源。这些数据被广泛用作待解释的因变量（对经济绩效决定因素的研究）和其他研究中的控制变量，作为控制各国经济资源差异的一种方式。工务指数会继续定期更新，以反映经济表现的变化。除了要求对这些更新提供支持外，pi还希望改进用于进行国际比较的方法。PWT部分依赖于联合国和世界银行开展的一个比较项目。这种比较集中在国民账户的支出方面（一个国家的消费、投资、政府活动支出、出口和进口）。比较经济体的另一种方法是考虑国民经济核算的生产方面。PWT团队正在与一个领先的欧洲研究小组合作，将这些生产比较纳入PWT。他们对各国的产量和收入进行了单独的估计，并使用了几种不同的分析方法，以评估哪种方法对未来维持PWT最有效。他们还开发了改进的模型，用于比较隐含增长率与通过国民收入账户计算的国民增长率之间的关系。问题是，当经济结构和相对价格都在随时间变化时，如何利用经济理论和实证方法来最好地解释经济增长。宾夕法尼亚大学世界经济表被研究人员、政策制定者和对国际经济比较感兴趣的学生广泛使用。
