An extension of the Holly and Gardiol (2000) and Baltagi et al. (2009) papers to the two way context, with heteroskedastic and spatially correlated disturbances is considered. One then derives a joint LM test for homoskedasticity and no spatial correlation. In addition, two conditional LM tests...

We re-examine the causality between the twin deficits by testing for Granger non-causality between BD and CAD based on extended causality tests initially developed by Toda and Yamamoto (1995). Using international data from a sample of twenty developed and developing countries, we find evidence...

In this paper we extend Taub (1979) approach for prediction in the context of the variance components model. The extension obtained is based on the two-way random-effect model with heteroskedasticity. Prediction functions are then obtained in three heteroskedasticity cases (heteroskedasticity on...

The long-run relationship between current account deficits, domestic income, foreign income and foreign interest rates are estimated based on Ivorian time series data. The empirical results suggest that terms of trade along with domestic income, French income, and foreign real interest rates...

ABSTRACTThis paper extends the ‘remarkable property’ of Breusch (Journal of Econometrics 1987; <b>36</b>: 383–389) and Baltagi and Li (Journal of Econometrics 1992; <b>53</b>: 45–51) to the three‐way random components framework. Indeed, like its one‐way and two‐way counterparts, the three‐way random...

This paper investigates the relationship between the terms of trade and current account deficits within a context of VECM. The results indicate that for the Coted'Ivoire there is a long-run relationship between the terms of trade and current account deficits. They also indicate that current...

The authors analyze the determinants of the efficiency levels reached by twenty one African water utilities. They assess efficiency through the estimation of a production frontier for the sector in Africa. The efficiency estimates confirm much of the common perceptions from partial productivity...

The purpose of this research has been 1.(1) to examine the similarity in the cost structure of energy sectors in the 86-order input-output tables (1967)2.(2) to examine changes for the periods 1958–1967 and 1967–1968, in energy sector cost structures. This analysis provides information on...
