Historical analysis of depreciation accounting -- The United States Steel experience

This paper examines the magnitude of the reporting bias inherent in the historical cost accounting of a firm\u27s physical capital. Reported depreciation data pertaining to U.S. Steel Corporation (currently USX) between 1939 and 1987 are compared with standardized historical cost figures and replacement cost estimates.

Thus, this analysis provides an illustration of one of the primary arguments for replacement cost accounting
