A Comparison of Estimated and Reported Historical Cost/Constant Dollar Data.
比较了Davidson-Weil模型估计的历史成本/不变美元数据与459家公司实际报告的数据，发现模型高估了销售成本、折旧费用和购买力损益。
Abstract ABSTRACT: SFAS 33 requires certain companies to present historical cost/constant dollar data. The disclosures provide a data base against which to compare results achieved by the Davidson-Weil historical cost/constant dollar data estimation model. This Note reports the result of research that was conducted to measure the degree of variation between surrogate historical cost/constant dollar data generated by the Davidson-Weil model and historical cost/constant dollar data presented by 459 companies. The Davidson-Well model estimate of historical cost/constant dollar cost of goods sold was in excess of reported amounts by an average of .54 percent, the model estimate of historical cost/constant dollar depreciation expense exceeded reported amounts by an average of 13.73 percent, and the model estimate of the purchasing power gain/loss exceeded reported amounts by an average of 68.3 percent.
