This survey reviews the theoretical literature on high impact entrepreneurship. The survey is guided in part by the recent classification changes at the Journal of Economic Literature (JEL) regarding entrepreneurship. The board voted to create a new classification code, L26, for...

The purpose of this paper is to test the possible catalysing role of in-house R+D in fostering the complementarity of innovative inputs on a sample of 3045 manufacturing firms drawn from the third Italian Community Innovation Survey (1998-2000). The interactions between four different sources of...

Being a "jack-of-all-trades" increases the probability of running an entrepreneurial venture successfully; but what happens to "jack-of-few-trades" who lack sufficient skills? This paper investigates a possible compensation mechanism between balanced skills and cities, and how this compensatory...

A principal-agent multitasking model is used to explore the effects of different tax schemes on innovation in a pure knowledge economy. Corporate taxes and labor income taxes can affect both the firm owner's and the employee's incentives to commit to innovative tasks, when the former compensates...

This paper analyzes whether firms conducting internal R&D and acquiring external high-tech equipment experience a complementarity effect. For German CIS data we conduct a complete set of indirect and direct complementarity tests refining the analysis by looking at various types of innovations...

We investigate the impact of actors' positions within regional innovator networks on their innovative performance. The networks of four selected regions are based on information on patent applicants and inventors. Count data regressions show positive effects on innovation of both the total...

This paper discusses the determinants of product innovation in young innovative companies (YICs) by looking at in-house and external R&D and at the acquisition of external technology in embodied and disembodied components. These input-output relationships are tested on a sample of innovative...

In this study we investigate the factors that shape the attitudes of scientists toward starting their own business or working in a private sector firm. The analysis is based on data collected from scientists working in the German Max Planck Society, a research institution devoted to basic...

Innovation processes are characterized by a pronounced division of labor between actors. Two types of externality may arise from such interactions. On the one hand, a close location of actors affiliated to the same industry may stimulate innovation (MAR externalities). On the other hand, new...

Ever since its introduction in the 1990s, the systems of innovations (SI) concept has received a great deal of attention from researchers and politicians. The systems of innovation policy (SIP) approach, which is based on the SI concept, is considered an alternative to neoclassical theory. Its...
