It is now widely believed that Foreign Direct Investment (FDI) affects positively the productivity of individual enterprises in the host economy and this is a main argument in favour of FDI. Although China is the largest recipient of FDI after the USA, there has been little empirical research as...

Unit root and stationarity test suggest that shocks to quarterly US, Japanese and UK inflation are infinitely persistent. Recently developed test based on threshold autoregressions are used to distinguish between non-stationarity and non-linearity. The evidence suggests that inflation is well...

One form of data reduction is cluster analysis which is used to separate detailed data into consistuent groups. In this paper we illustrate a useful application of cluster analysis to the data reduction of detailed discrete responses of a type that are often found in large surveys.

A number of recent papers have employed the BDS test as a general test for mis-specification for linear and nonlinear models. We show that for a particular class of conditionally heteroscedastic models, the BDS test is unable to detect a common mis-specification. Our results also demonstrate...

This paper describes the estimation and testing of regression models that include multivariate generated or computed regressors in the presence of heteroskedasticity in the cross-section case. Heteroskedasticity is often a problem in cross-section data and the usual tests for its presence can...

It is common practice to examine empirical models in which one of the regressors is constructed as the weighted average or sum of a set of series that includes the dependent variable. Examples include models relating money and wealth, consumption and income and regional and national...
