Researchers prefer to use a demand system that best fits their data. This paper examines a nonnested test of comparison between the quadratic expenditure system (QES) and the almost ideal demand system (AIDS). We determine which model is more suitable by analyzing the value and the significance...

This paper shows that the recently proposed tests of linear and logarithmic transformations for integrated processes against each other by Kobayashi and McAleer (1999) are severely biased for alternative hypotheses when the true data generating process is a stochastic unit root. An empirical...

In many published studies involving discrete class, a large class of models has been utilised without apparent consideration of either the statistical or the behavioural relationships that exist between different model structures. In this paper the authors consider a number of alternative ways...
