This paper reviews the current state of indicators of the activity of innovation and how they are presented for use in the policy process leading to a discussion of the development of new indicators, some outside of the business sector, which raises questions about the definition of innovation....

This study suggests that individual time is an important factor that needs to be considered in innovation research. We define two types of time work time and free time. We find that work time has a positive but diminishing effect on innovative output such that after a certain point the...

Categorization is an important phenomenon in science and society, and classification systems reflect the mesoscale organization of knowledge. The Yule-Simon-Naranan model, which assumes exponential growth of the number of categories and exponential growth of individual categories predicts a...

This paper discusses the growth model with environmental constraints recently presented in (Acemoglu et al., 2011) which focuses on the redirection of technical change by climate policies with research subsidies and a carbon tax. First, Acemoglu et al.'s model and chosen parameters yield...

A fundamental question is how to detect likely successful anticancer treatments based on nanotechnology. We confront this question here by analysing the trajectories of nanotechnologies applied to path-breaking cancer treatments, which endeavour to pinpoint ground-breaking and fruitful...
