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...

86-order interindustry transactions tables for selected years are used to assess the forward and backward linkage effects of energy sectors, 1958–1970, in the U.S. economy. The magnitude of the linkage effects were obtained by calculating intermediate input and demand coefficients. The crude...

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...
