| Abstract: | We present a model that links innovation effort to economic performance, along the lines of the Crépon et al (1998) model. However, in contrast to Crépon et al, that analyze R&D intensive manufacturing sectors, the present application examines the relationship between innovation and performance for services sectors. This is relevant since much effort has been made to explore that relationship for manufacturing but very little is known about it in the case of services sectors. In trying to fulfill this gap the paper uses firm-level data from the Second Community Innovation Survey to estimate a simultaneous equations model for firms in ten services sectors in Portugal. The present model also differs from former approaches by the specific explanatory structure proposed to estimate the complex relationship between innovation and economic performance. Instead of estimating a direct link between innovation and labor productivity, three specific relationships were put forward. The first of them explains the innovation effort intensity (an input in the innovation process). The second one relates service innovation (an output of the innovation process) to effort intensity and to other explanatory variables. Finally, the third relationship links labor productivity to both service innovation and effort intensity considering also some other influences. Sensitivity analysis of the results to alternative estimation techniques was performed. |

| Abstract: | Open source software (OSS) has recently emerged as a new way to organize innovation and product development in the software industry. This paper investigates the factors that explain the investment of profit-oriented firms in OSS products. Drawing on the resource-based theory of the firm, we focus on the role played by pre-OSS firm assets both upstream and downstream, in the software and the hardware dimensions, to explain the rate of product introduction in OSS. Using a self-assembled database of firms that have announced releases of OSS products during the period 1995-2003, we find that the intensity of product introduction can be explained by a strong position in software technology and downstream market presence in hardware. Firms with consolidated market presence in proprietary software and strong technological competences in hardware are more reluctant to shift to the new paradigm. The evidence is stronger for operating systems than for applications. The fear of cannibalization, the crucial role of absorptive capacity, and complementarities between hardware and software are plausible explanations behind our findings. |

| Abstract: | This study focuses on the relationship between industrial clustering and innovation. It contributes to this literature by showing two empirical properties of the cluster learning process: first, that the structure of the knowledge network in a cluster is related with the heterogeneous distribution of firm knowledge bases and, second, that business interactions and inter-firm knowledge flows are not highly co-occurring phenomena. In particular, this paper highlights how the heterogeneity of firms’ knowledge bases generates uneven distribution of knowledge and selective inter-firm learning. This study has been based on empirical evidence collected at firm level in three wine clusters in Italy and Chile. Methods of social network analysis have been applied to process the data. |
