Section 2 of this paper suggests that economics has long sought to colonise other social sciences. It has, however, only achived limites success because of its alien methods and its need to take the social as given. Section 3 argues that there is now a newer version of economic imperialism...

This paper considers the question whether it is possible, using information about only the distribution of earnings, to identify some of the labour supply incentive effects of a tax and transfer system.

Research by Ghali (1999) tested for the existence of causality between wages and prices in United States' aggregate data using a multivariate cointegration framework. We show that Ghali's model is misspecified and that the correct specification leads to a different interpretation of the long-run...

New results in the asymptotic theory of Markov processes are applied to analysis of the long-run behaviour exhibited by optimal growth models with unbounded productivity shock. The techniques developed here are geometrically intuitive, and are shown to imply global stability for a popular model...

Indirect estimation methods are proposed for estimating univariate ARFIMA , as well as more complex multivariate VARFIMA models. Special attention is given to comparing the finite sampling properties of the indirect estimator with Sowell's (1992a) exact time domain maximum likelihood estimator...

The traditional textbook approach to avoiding the dummy trap problem is to delete a category from each qualitative variable. We illustrate an alternative constraint introduced by Sweeney and Ulveling (1972) which can be used to transform conventional dummy variable coefficients. This constraint...
