Abstract: Analyses involving CES and VES production functions indicate that the constant-returns-to-scale CES model is an adequate representation of large-scale firms in the wheat-flour milling, rice husking, sugar refining and edible-oil processing industries in Pakistan. The hypothesis that these four food-processing industries have the same elasticities of substitution is not rejected. The pooled elasticity estimate for the food-processing industries is significantly different from zero, but not significantly different from one
