This paper identifies some of the more important issues raised by the growing use of 'international data services'. The author describes how telecommunications have become increasingly important in the resolution of many different issues, including the information gap, international networking,...

Trade in telecommuncations and computing services, particularly trade in data-related services, offers potential for economic growth in all sectors. This article raises a number of issues which need to be settled in international fora before the greatest benefits can be reaped. Differing...

We develop non-nested tests in a general spatial, spatio-temporal or panel data context. The spatial aspect can be interpreted quite generally, in either a geographical sense, or employing notions of economic distance, or when parametric modelling arises in part from a common factor or other...

Power law or generalized polynomial regressions with unknown real-valued exponents and coefficients, and weakly dependent errors, are considered for observations over time, space or space-time. Consistency and asymptotic normality of nonlinear least squares estimates of the parameters are...

Central limit theorems are developed for instrumental variables estimates of linear and semiparametric partly linear regression models for spatial data. General forms of spatial dependence and heterogeneity in explanatory variables and unobservable disturbances are permitted. We discuss...

Panel data, whose series length T is large but whose cross-section size N need not be, are assumed to have a common time trend. The time trend is of unknown form, the model includes additive, unknown, individual-specific components, and we allow for spatial or other cross-sectional dependence...

Nonparametric regression with spatial, or spatio-temporal, data is considered. The conditional mean of a dependent variable, given explanatory ones, is a nonparametric function, while the conditional covariance reflects spatial correlation. Conditional heteroscedasticity is also allowed, as well...

As the dust settles on the Labour leadership race and the Labour opposition begins a new phase under Ed Miliband, Peter Robinson takes a hard look at what politicians of all colours might learn from the rollercoaster ride of the Blair-Brown years. Copyright (c) 2010 The Author. Public Policy...
