Price Indexes for R and D Inputs, 1969–1983
基于约100家企业的实际价格和支出数据，构建了首个研发价格指数，发现官方使用的GNP平减指数低估了研发领域的通胀率，对研发预算和生产率研究有参考价值。
This paper presents the first R and D price indexes based largely on actual prices and expenditures reported by firms. The results, based on a carefully designed sample of about 100 firms, show that the GNP deflator, which is used in the official government R and D statistics, has tended to underestimate the rate of inflation in R and D. For managerial and economic purposes, such as R and D budgeting and productivity studies, these indexes should be of widespread use.
