This paper examines the practical usefulness of two new journal performance metrics, namely the Eigenfactor score, which may be interpreted as measuring “Journal Influence”, and the Article Influence score, using the Thomson Reuters ISI Web of Science (hereafter ISI) data for 2009 for the...

We show that the asymptotic distribution of the ordinary least squares estimator in a cointegration regression may be bimodal. A simple case arises when the intercept is erroneously omitted from the estimated model or in nonlinear-in-variables models with endogenous regressors. In the latter...

The papers in this special issue of Mathematics and Computers in Simulation cover the following topics. Improving judgmental adjustment of model-based forecasts, whether forecast updates are progressive, on a constrained mixture vector autoregressive model, whether all estimators are born equal....

This paper examines the practical usefulness of two new journal performance metrics, namely the Eigenfactor score, which is said to measure “importance”, and Article Influence score, which is said to measure “prestige”, using the most recent ISI data for 2009 for the 200 most highly...

We present the results of a simulation study into the properties of 12 different estimators of the Hurst parameter, H, or the fractional integration parameter, d, in long memory time series. We compare and contrast their performance on simulated Fractional Gaussian Noises and fractionally...

This paper reviews literature on China’s energy economics, focusing especially on: i) the relationship between energy consumption and economic growth, ii) China’s changing energy intensity, iii) energy demand and energy -capital and -labor substitution, iv) the emergence of energy markets in...

The paper investigates energy market integration in China by employing univariate, and panel-based unit root tests and Granger causality tests applied to a new, energy price data set. We identify price series that converge either to absolute or relative price parity. In addition we estimate the...

It is now recognized that long memory and structural change can be confused because the statistical properties of times series of lengths typical of many nancial and economic series are similar for both mod- els. We propose a new test aimed at distinguishing between unifractal long memory and...

With its rapid economic growth, China’s primary energy consumption has exceeded domestic energy production since 1994, leading to a substantial expansion in energy imports, particularly of oil. China’s energy demand has an increasingly significant impact on global energy markets. In this...

During the late nineteenth century the physical stature of New Zealandborn men stagnated, despite an apparently beneficial public health environment and growth in per-capita incomes. Stature varied by social class, with professionals and men in rural occupations substantially taller than their...
