The Variation of Technical Coefficients in the Antifriction Bearing Industry
Almarin PhillipsThe temporal variations in a few input-output coefficients for the antifriction bearing industry are noted. It appears that these variations are due to cyclical phenomena rather than to price changes, technological change, or variations in product mix. The coefficients for the individual plants in the industry tend to move parallel to the coefficients for the industry as a whole, but there are large differences among the plant coefficients at any given time. Some of these differences are associated with the degree of integration of the plants and the type of products being made, but most of the inter-plant differences cannot be explained with conventional census-type data.
