The impact of health information technology on hospital productivity
估计了医院生产函数中健康信息技术的私人回报，发现尽管边际产品高，但总收益不大；IT投入增长超210%，仅贡献约6%的增加值增长；非营利医院IT投资更多且方式不同。
Health information technology (IT) has been championed as a tool that can transform health care delivery. We estimate the parameters of a value‐added hospital production function correcting for endogenous input choices to assess the private returns hospitals earn from health IT. Despite high marginal products, the total benefits from expanded IT adoption are modest. Over the span of our data, health IT inputs increased by more than 210% and contributed about 6% to the increase in value‐added. Not‐for‐profits invested more heavily and differently in IT. Finally, we find no compelling evidence of labor complementarities or network externalities from competitors' IT investment.
