This paper concerns the problem of assessing autocorrelation of multivariate (i.e. systemwise) models. It is well known that systemwise diagnostic tests for autocorrelation often suffers from poor small sample properties in the sense that the true size overstates the nominal size. The failure of...

The article illustrates the use of the forward search to provide robust analyses of econometric data. The emphasis is on informative plots that reveal the inferential importance of each observation. The division of observations into “good” and “bad” leverage points is shown to be...

This paper reports the results of simulation tests on various models that have been employed by researchers in testing the share market response to information releases. The study employs methodology similar to that used by Brown and Warner (1980) in the United States. This study based on...

This paper provides a general overview of the social, environmental, and economical issues related to biofuels and a review of economic modeling of biofuels. The increasing importance of biofuels is driven primarily by government policies since currently available biofuels are generally not...

This paper proposes a new set of transformed polynomial functions that provide a flexible setting for nonlinear autoregressive modeling of the conditional mean while at the same time ensuring the strict stationarity, ergodicity, fading memory and existence of moments of the implied stochastic...

A.W.H. Phillips is little known to the economics profession today, except at the creator of the Phillips curve. Bollard's engaging biography tells the story of a provincial New Zealander and practical engineer, who emerges as a hero in World War II, and plots a spectacular rise from 3rd class...

The aim within this paper is to analyze the difference between momentum and contrarian portfolios constructed under the cross-sectional and time-series analysis, within the commodity futures markets. The returns indicate that the contrarian portfolios are the most profitable, as well as it's...

This study investigates the predictability of outlook hog price forecasts released by Iowa State University relative to alternative market and time-series forecasts. The findings suggest that predictive performance of the outlook hog price forecasts can be improved substantially. Under RMSE,...

Until recently, it is hard to find studies to estimate how much the total economic losses for U.S. or other states by the BSE incidents except one dominant study by Devadoss et al (2005), which used CGE (Computable Generalized Equations) model for U.S. However, they are not reporting the direct...
