The consequences of evolving competition on the components of firms' profits: recent evidence from the U.S. telecommunications industry

Article Abstract:

The effects of intensified competition on the profitability of US telecommunications companies were analyzed through a multi-period, multi-output ratio analysis model. Industrial performance ratios from 1981 to 1991 were examined. The ratios were productivity, price recovery, product mix and capacity utilization. It was discovered that the profitability trend of the period 1981 to 1987 were reversed from 1988 to 1991, indicating that increased competition was lowering the profitability of firms. Firms, however, have stabilized their profit margins through increased productivity.
