Measuring the Spillovers from Technical Advance: Mainframe Computers inFinancial Services

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.
