Industrial research output and productivity according to age in India

Abstract: Mathematical models of aging were used to examine industrial research output by scientists and inventors varying in professional and chronological age and working at the Council of Scientific and Industrial Research (CSIR) in India. A non-linear relationship between lifetime productivity and career and chronological age was found. Research papers and processes developed increase as scientists age, but productivity in terms of patents, processes under utilisation and technical reports declines. In the latter three types of output, researchers at the start of their career produce at a lower rate, which grows and reaches its peak at 30–35 years of experience and then tapers off. Differing socio-economic environments, particularly changing science and technology policies, have more influence on productivity than does age. Copyright , Beech Tree Publishing.
