U.S.-Austria Cooperative Research: Testing and Estimation ofModels with Structural Change

该奖项支持耶鲁大学的Donald Andrews教授与奥地利维也纳技术大学计量经济学与运筹学研究所的Werner plobberger教授在经济学研究方面的合作。在1991年plobberger博士访问耶鲁大学期间，这些调查人员开始联合研究结构变化的计量经济学。他们发表了两篇论文，建立了新的最优测试，用于未知变化点的情况，以及仅在替代方案下出现干扰参数时的测试问题。现在plobberger博士已经回到维也纳，他们提议继续他们的合作研究，重点关注几个相关主题。这包括：1)进一步分析最优试验的特性；2)多种结构变化试验的处理；3)断点估计；4)在这种情况下，似然比测试是不可接受的。这一共同努力将美国一位领先的年轻计量经济学家与一位备受尊敬的欧洲同事联系起来，共同追求理论和应用经济学领域的最新研究。这种合作研究可能会推动计量经济学的理论和实践。在将要开发的方法中，有一些在被分析的基本关系发生巨大变化时对应用经济学研究特别有用。其中一个领域是正在进行的关于全球气候变化的经济影响的重要研究。

This award supports Professor Donald Andrews of Yale University to collaborate in economics research with Professor Werner Ploberger of the Institute of Econometrics and Operations Research of the Technical University of Vienna, Austria. These investigators began joint studies in the econometrics of structural change during a 1991 visit to Yale University by Dr. Ploberger. They produced two papers establishing new optimal tests for situations with an unknown changepoint and for testing problems when a nuisance parameter appears only under the alternative. Now that Dr. Ploberger has returned to Vienna, they propose to continue their collaborative research focusing on several related topics. These include: 1) further analysis of the properties of the optimal tests; 2) treatment of tests of multiple structural changes; 3) estimation of breakpoints; and 4) inadmissibility of likelihood ratio tests in this context. This joint effort links one of the leading young econometricians of the U.S. with a highly regarded European colleague to pursue state of the art research in theoretical and applied economics. This collaborative research is likely to advance both econometric theory and practice. Among the methods which will be developed are some especially useful for applied economics research when the basic relationships being analyzed change dramatically. One such area is the important research being done on the economic implications of global climate change.
