An integrated assessment of productivity and efficiency impacts of information technology investments: Old data, new analysis and evidence

摘要: We reexamine the •Information Technology (IT) productivity paradox• from standpoints of theoretical basis, measurement issues and potential inefficiency in IT management. Two key objectives are: (i) to develop an integrated microeconomic framework for efficiency assessment using developments production economics, (ii) apply a dataset used prior research with mixed results obtain new evidence regarding contribution. Using stochastic frontier economics involving behavioral assumptions profit maximization cost minimization, we unified basis assess both impacts investments. The is applied manufacturing database spanning 1978–1984. While previous this found contribution capital, show negative marginal important study attributable primarily choices deflator modeling technique. Further, by ignoring investment management, studies that have reported positive may significantly underestimated true IT. This impact consistent across multiple model specifications, estimation techniques capitalization methods. analysis shows while there were significant technical, allocative scale inefficiencies, inefficiencies reduced increase intensity. Given organizational units our sample increased their intensity during time period covered study, management was taking step right direction increasing share capital inputs. Our add small body MIS literature which reports returns
