The paper considers tests for the presence of a random walk component in a stationary or trend stationary time series and extends them to series which contain structural breaks. The locally best invariant (LBI) test is derived and the asymptotic distribution obtained. Then a modified test...

This paper is an empirical study on the labor force in (Peninsular) Malaysia. It applies both parametric and semiparametric sample selection methods to the estimation of wage equations. These equations are then used to assess the extent of gender ?discrimination? - i.e., the part of the wage-gap...

We propose a modification of kernel time series regression estimators that improves efficiency when the innovation process is autocorrelated. The procedure is based on a pre-whitening transformation of the dependent variable that has to be estimated from the data. We establish the asymptotic...

Varying-coefficient linear models arise from multivariate nonparametric regression, nonlinear time series modelling and forecasting, functional data analysis, longitudinal data analysis, and others. It has been a common practice to assume that the vary-coefficients are functions of a given...

There is a growing literature on unit root testing in threshold autoregressive models. This paper makes two contributions to the literature. First, an asymptotic theory is developed for unit root testing in a threshold autoregression, in which the errors are allowed to be dependent and...

Shillony: Paper examines how Japan's imperial dynasty dependent on the male line of succession has lasted so long and analyses how it will overcome its present difficulties. An Advisory Panel was created to recommend future policy to the Koizumi cabinet but its report in 2005 was criticized. The...

This pamphlet contains two papers given at the Suntory-Toyota International Centre, the first at the symposium held on 5 July 1991 (other papers were issued in IS/91/227), and the second at the symposium on 22 May 1990 (whose papers were issued as pamphlet IS/90/219). Mrs Harries is the joint...

Dr Yasutomi who had earlier contributed an essay on Japan's financial activities in Manchuria down to 1931 to the International Studies series, completed with this essay the topics he studied during his two years as Research Associate. It explains how Manchuria became in 1935 part of the Yen...
