Empirical studies of the diffusion of innovations have not addressed adequately econometric problems that are characteristic of such analyses. Reanalysis of data for five innovations using an estimator with desirable statistical properties results in a considerably revised estimate of the impact of prospective reimbursement on diffusion.
对创新扩散的实证研究尚未充分解决此类分析所特有的计量经济学问题。使用具有理想统计特性的估计量对五项创新的数据进行重新分析，会得出对预期报销对扩散影响的大幅修正估计。
