Measuring the Spillovers from Technical Advance: Mainframe Computers in Financial Services
提出从新技术的派生需求曲线推断采用行业支付意愿的方法，测量金融服务业采用大型计算机带来的巨大社会收益，这些收益未被计算机制造商获取。
Measuring the social gains from recent technological advances is difficult because there are no output indexes from some important adopters. Measurement methods that infer the willingness-to-pay of theadopting industries from the derived demand curve for a new technologyovercome this difficulty. The derived demand for high-speed computersfor use in banks, finance, and insurance is shown to imply a very largesocial gain to computerization that is not captured by computer manufacturers.
