This paper looks at the special characteristics of radical inventions. It tries to identify those variables that differentiate radical inventions from non-radical inventions. Since radical inventions are very important for the economy as a whole and for the individual firm performances,...

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...

We propose a model where both R&D and ICT investment feed into a system of three innovation output equations (product, process and organizational innovation), which ultimately feeds into a productivity equation. We find that ICT investment and usage are important drivers of innovation in both...

Technological change is a vital human activity that interacts with geographic factors and environment. The purpose of the study here is to analyse the relationship between geo-climate zones of the globe and technological outputs in order to detect favourable areas that spur higher technological...

An interesting problem in the economics of innovation and strategic management of labs is to explain the drivers of breakthroughs and paradigm shifts in science. This study confronts the issue by analysing a main case study the technological determinant of the discovery of quasi-periodic...

In this paper we analyse economic development through the lenses of a newly developed index the structural modernization index. This index combines two dimensions that have been widely invoked as prime drivers of economic development namely, structural change and technological catch up. For each...

Using Dutch data we empirically investigate how financing and innovation vary across firm characteristics. We find that when firms face financial constraints, debt financing and innovation choices are not independent of firm characteristics, and RD slows down. In the absence of financial...

This paper reviews the existing evidence regarding the effects of technological andnon-technological innovations on the productivity of firms and the existence ofpossible complementarities between these different forms of innovation.
