These equations are incorporated into a simultaneous system and estimated using a sample of fifty­-four Canadian industries. The system is then used to examine the effect of the foreign sector upon the struc­ture, conduct and performance of Canadian manufacting industry. Particular attention is given to the econometric problems of simultaneity and multicollinearity and two stage ridge estimation is used to deal with them. The study emphasises the consequences of inappropriate estimation techniques by comparing these results with the ordinary least squares and two least squares estimates obtained from the same sample.75 pagesAvailable to the World Wide WebThesis
