On the Dynamic Properties of Asymmetric Models of Real GNP
考察了用于研究实际GNP非对称性的几种参数模型，发现尽管它们捕捉非对称性的方式不同，但动态性质非常相似。
There is now a substantial body of evidence that suggests business cycles are asymmetric. However, the evidence has been accumulated using a wide array of statistical techniques and, consequently, is based on various definitions of asymmetry. This paper examines several parametric models that have been used to study asymmetries in real GNP. Although these models capture asymmetries in very different ways, their dynamic properties are remarkably similar. © 1997 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
