We present a dynamic duopoly model of technical innovation where R&D costs decrease exogenously with time, and inter-firm knowledge spillover lowers the second comer's R&D cost. The spillover effect only becomes available after a disclosure lag. These features allow us to identify a new type of...

This paper discusses the link between R&D and productivity across the European industrial and service sectors. The empirical analysis is based on both the European sectoral OECD data and on a unique micro longitudinal database consisting of 532 top European R&D investors. The main conclusions...

A wider RJV extension hastens process innovations at the cost of increasing collusion in the final market. In a Cournot model, an extended RJV is welfare enhancing only when the Antitrust Authority is strong, so that the increase in distortion is limited, and when the size of the technical...

This paper investigates the determinants of the choice of different types of innovative input (R&D and technological acquisitions) and their relationship with different innovative outputs (product and process innovation), distinguishing between firms of different ages (mature vs young). In order...

The literature has pointed to different causes to explain the productivity gap between Europe and United States in the last decades. This paper tests the hypothesis that the lower European productivity performance in comparison with the US can be explained not only by a lower level of corporate...

The purpose of this study is to investigate the relationship between a firm's R&D expenditures considered as an investment in knowledge, and its productivity, looking at sectoral peculiarities which may emerge; to this end, we use a large unique longitudinal database consisting of 1,809 US and...

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 its embodied and disembodied components. These ‘innovative’ input-output relationships are tested on a...

This paper analyses the determinants of product innovation in Italian young innovative companies (YICs) by looking at in-house and external R&D and at the acquisition of external technology in its embodied and disembodied components. A Tobit approach is applied to study jointly the occurrence of...

This paper investigates, both theoretically and empirically, the implications that complementary assets needed for the formation of start-ups - proxied by the ease of access to financial resources - have on the innovative efforts of incumbent firms. In particular, we develop a theoretical model,...
