Research in Economic Theory

彼得施密特密歇根州立大学SBR-9514750 拟议的研究将涵盖计量经济学理论的三个主题。 第一部分将讨论经济冲击的影响完全消失但非常缓慢的情况。 将进行研究，以确定哪些冲击最能体现这种现象，以及如何估计与这些冲击有关的变量。 第二部分将发展面板数据的估计方法。 面板数据涉及在个人或公司层面上随着时间的推移进行重复观察;它们允许对某些类型的不可观察数据进行统计控制并确定动态关系。 第三部分将继续进行关于生产前沿和经济单位效率的估算工作。 该研究将开发效率估计的统计精确度的测量方法，并将扩展对效率测量中出现的复杂性的了解， 所进行的研究将对其他在研究中使用计量经济学模型的经济学家有用。

Peter Schmidt Michigan State University SBR-9514750 The proposed research will cover three topics in econometric theory. The first part will deal with instances in which the effects of economic shocks die off completely, but very slowly. Research will be undertaken to determine which shocks are best characterized by this phenomena and how to estimate variables related to these shocks. The second part will develop estimation methods for panel data. Panel data involve repeated observations over time at the individual or firm level; they allow statistical control for certain types of unobservables and the identification of dynamic relationships. The third part will continue work on the estimation of production frontiers and the efficiency of economic units. The research will develop measures of the statistical precision of efficiency estimates and will extend knowledge of complications arising in efficiency measurement, The research undertaken will be useful to other economists who use econometric models in their research.
