The purpose of this paper is to propose an extension of the conventional input-output forecasting technique to allow projection of gross output of product-specific sectors. A single seetor of particular interest in the United States national table is disaggregated into a number of smaller, product-specific sectors. These sectors, along with several other sectors engaged in significant trade with the product-specific sectors, form a compact input-output model. The model is employed in a conventional manner to project gross output of the modeled sectors.
