We use a survey data collected from 398 Finnish manufacturing firms for the years 2002 and 2005 to empirically explore ...

We consider three dimensions of sector performance: entry time, service prices and diffusion. We address the question of non-random selection arising from cross-country differences in the timing of the commercialization of new technologies. Our empirical exploration shows that this type of sample selection may indeed be a substantial problem in cross-country studies on technology diffusion and yield biased estimates of the policy variables of interest. Our estimation results suggest that standardization accelerates 2G entry and diffusion, although within-standards competition triggers less aggressive price competition than between-standards competition. We also find that an early monopolist will price more aggressively to build up an installed base. Furthermore, we find that liberalizing markets for incumbent technologies (i.e., fixed line telephony) has accelerated the commercialization of 2G.

In other words, the larger the knowledge pool of an inventor entering (leaving) the firm, the more the firm's innovation performance increases (decreases). However, our separate estimations for six different technology classes suggest that this does not apply for all technologies. Our data indicate that the knowledge flows are mobile inventor-specific for chemicals and pharmaceuticals and mechanical engineering such that the mobility of an inventor to a firm increases its innovation performance but the mobility of an inventor from a firm does not affect its innovation performance. We further find that particularly innovation coopetition (i.e., collaboration with a firm's competitors) is an important source of knowledge spillovers.

Our estimation results further show that the OSS business model adopters have not become notably less productive after beginning to supply OSS.

The data is restricted to those patents between the years 1980-2003 that have two or more assignees, i.e. we consider only joint patents. We find some evidence that technological or product market

We find a positive contemporary relationship between all business subsidy types and employment growth. Our findings suggest that R&D subsidies further contribute to the firms? employment for one year after and employment and other subsidies for three years after the reception of subsidies. After that, the differences between the subsidized and non-subsidized firms vanish. We further find, in line with the empirical studies of and , that both product innovation and sales growth from a firm?s old products contribute to the firm?s employment growth. Process innovation, instead, does not seem to have any significant effect on employment Jelcodes:L10,J23

We use survey data collected from 170 Finnish software companies to investigate the determinants of the choice of OSS production. Our study focuses on the role of a firm’s absorptive capacity in its adoption of OSS supply as a business strategy. We find that the quality of a firm’s human capital indeed matters : those companies that supply OSS solutions also have relatively more highly educated employees. However, our data do not indicate that a firm`s accumulated intellectual property affects in any significant way its choice to apply OSS-based strategy.

We consider all software used in a firm as its software product and categorize it into related, but distinct subsystems : the core subsystem (Operating Systems), and Desktop and En-terprise Applications, which we define as peripheral subsystems. Adoption is studied across those sub-systems.

It remains uncertain, however, if diffusion processes in developing countries follow a similar pattern and are governed by similar determinants as in industrialized countries. Present results suggest that this is indeed the case and that technological progress in developing countries can be fostered by changing the competitive and regulatory environment and capping service prices if possible.

In particular, we focus on the latest applied work, including case studies and empirical work as well as refinements of the established theoretical results.
