Abstract
Productivity of blast furnaces in India is studied by disaggregating the production process and the utilization process. A dimension‐reducing nonparametric approach—projection pursuit regression—is used. We find that productivity can be increased significantly by improving the quality of coal. There is no evidence that executives have a positive marginal product. The production workers have a negative marginal product for the production process and a positive one for the utilization process. But the training of executives has a positive effect whereas that of the production workers has a negative effect on productivity. Copyright © 2004 John Wiley & Sons, Ltd.
