A multivariate statistical analysis of the characteristics of problem firms in Hong Kong

This paper presents a two-group discriminant analysis of the characteristics of problem firms in Hong Kong. The purpose of this study is to identify and describe the common financial characteristics which distinguish problem firms from nonproblem firms.Benjamin Y.K.

Rational and polynomial lags: The finite connection

This article demonstrates that, for a finite distributed lag, the polynomial distributed lag (PDL) approximation suggested by Almon is a special case of the rational lag method formalized by Jorgenson. The proof relies upon the fact that the PDL estimator imposes differencing restrictions upon the parameters while rational lag methods impose quasi-differncing restrictions. Because of this relationship, the PDL restrictions are nested inside the rational lag ones, and this provides for a sequence of tests to discriminate between the two. An example is performed and an appendix describes an asymptotically efficient two-step estimator.
