The lag in innovation in Italy vis-�-vis the other main industrial countries is one of the effects of the fragmentation of the production system into many small firms that have trouble bearing the high cost of R&D and taking the related risks. Such other causes as shortages in human capital...

This paper evaluates the causal effect of issuing equities on the probability that a firm will engage in R&D activity. Equity is a preferable source of external finance for innovation than debt. It does not require collateral, does not exacerbate moral hazard problems connected with the...

The economic performance of a country depends, among other things, on the strategies and structures of its firms. In the framework that is designed by institutions and policies and determined by technology and macroeconomic cycles, entrepreneurs decide how to allocate available resources in...

Innovation in SMEs exhibits some peculiar features that most traditional indicators of innovation activity do not capture. Therefore, in this paper, we develop a structural model of innovation which incorporates information on innovation success from firm surveys along with the usual R&D...

The analysis of patent and citation data has become a popular source of evidence on localized knowledge spillovers and innovation. Nevertheless, one aspect has been overlooked: the patent distribution across inventors is extremely skewed, as many inventors -- the comets -- register one or few...

This paper provides theoretical background to the increasing R&D cooperation among firms and public research institutions. We find that R&D spillovers may impede cooperation among firms or research institutions even when the cost of forming a link is negligible. Further, the presence of...

The paper investigates R&D and ICT investment at firm level, assessing their relative importance and the extent to which they are complements or substitutes. We use data on a large unbalanced panel sample from four consecutive waves of a survey of Italian manufacturing firms, together with a...

In the last decade R&D expenditure in Italy has been lagging at a bare 1.2-1.3 per cent of GDP. Its private share is low by international standards and Italian firms take out only a small number of patents. External sources of innovation, however, are available to firms. This work aims at...
