How Rapidly Does New Industrial Technology Leak Out?

Mansfield, Edwin·1985·The Journal of Industrial Economics

Abstract

There have been no systematic empirical studies of the speed at which various kinds of technological information leak out to rival firms. To help fill this gap, data were obtained from 100 American firms. According to the results, information concerning development decisions is generally in the hands of rivals within about 12 to 18 months, on the average, and information concerning the detailed nature and operation of a new product or process generally leaks out within about a year. These results have important implications both for incentives for innovation and for public policies aimed at stemming the outflow of technology.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
