Great scientific output typically peaks in middle age. A classic literature has emphasized comparisons across fields in the age of peak performance. More recent work highlights large underlying variation in age and creativity patterns, where the average age of great scientific contributions has...

Teamwork pervades modern economies, yet teamwork can make individual roles difficult to ascertain. In the sciences, the canonical "Matthew Effect" suggests that eminent team members garner credit for great works at the expense of less eminent team members. We study this phenomenon in reverse,...

The emergence of a mass market for electric vehicles (EVs) offers considerable development opportunities for resource exporters, given their intensive raw material requirements, including for cobalt, nickel, lithium, copper, aluminium, and manganese. To exploit the benefits of new demand,...

Great achievements in knowledge are produced by older innovators today than they were a century ago. Using data on Nobel Prize winners and great inventors, I find that the age at which noted innovations are produced has increased by approximately 6 years over the 20th Century. This trend is...

This paper presents a new framework for human capital measurement. The generalized framework can (i) substantially amplify the role of human capital in accounting for cross-country income differences and (ii) reconcile the existing conflict between regression and accounting evidence in assessing...

Getting science policy right is a core objective of government that bears on scientific advance, economic growth, health, and longevity. Yet the process of science is changing. As science advances and knowledge accumulates, ensuing generations of innovators spend longer in training and become...
