We analyzed the scientific productivity of a sample of academic scientists that contribute to the field of Materials Science in the post-patenting period, by means of several econometric techniques suitable to treat unobserved heterogeneity, excess zeros and incidental truncation. Although...

[It is widely acknowledged that firms performing R&D investments are very likely to undergo financial constraints (FC) due to their specific characteristics, which make external debt an imperfect substitute for internal finance,especially for small sized enterprises. This situation calls into...

This paper contributes to the debate upon the trade-off between science and technology by looking at how the scientific performances of a researcher relate ex-ante to his/her attitude to patent, during his/her academic career. We run an event history analysis explaining the hazard for a...

We study the effect of financing constraints on the decision to do R&D and on the level of R&D investment using survey data and complete financial accounting data on a large number of Italian manufacturing SMEs from 2001 to 2003. We use a direct indicator of credit constraints and employ an...

The main goal of this paper is to assess the impact of product innovation on the economic performance of firms operating in medium and high-tech industries in general and of SMEs in particular. Using information from a large and unique dataset on Italian firms we estimate, by means of propensity...

This paper focuses on niche entry patterns in the LAN equipment industry in the 1990s. We analyze an original data-set of LAN equipment consisting of more than 1,000 hubs and switches marketed between 1990 and 1999. Modularity emerged as a design strategy that supported incumbent firms’...

The rise of Fast Ethernet as the dominant standard for high speed connection in the Local Area Network industry is chosen to analyse the relevance of increasing returns and network externalities in determining the speed of standard diffusion. Although it was not the first standard to emerge,...

We investigate the relationship between product innovation and firm survival for a sample of 121 firms in a high-tech industry. We find that location near the technological frontier is an important determinant of fim survival. Firms located near the frontier are also more likely to be acquired...

This work is concerned with the determinants of innovations and competition of technologies in the case of the Local Area Network industry. It focuses in particular on two suppliers of LAN components: the access technology industry and the internetworking industry. Two elements driving the...

Technical change can affect existing products very rapidly and at an uneven pace depending on the type and on the age of an industry. In young and fast growing industries, the process of technological change usually entails a series of improvements in existing products that affect their...
