Small and medium-sized enterprises (SMEs) are supposed to be less likely to conduct formal R&D because of the lack of financial resources, weaker competencies, and the absence of scale and scope economies. These limitations may be overcome when an SME belongs to a business group. Empirical...

Several empirical papers have shown that firms belonging to business groups have a higher propensity to engage in R&D. The purpose of the paper is to demonstrate that this higher propensity depends on the ownership share of controlled companies, besides the presence of co-ordination mechanisms....

In this paper we analyse whether belonging to a business group enhances firms’ R&D propensity and intensity as a result of the greater opportunities to co-ordinate R&D strategies and internalize the positive spillovers. We analyse the organization of R&D management within a business group and...

Notre étude a pour objectif de mesurer les effets spatiaux des externalités de connaissances sur la production de brevets des firmes, au niveau des villes. Nous utilisons une méthode originale basée sur le maximum d'entropie généralisé. Cette méthode permet de tester l'auto-correlation...

Our study aims to measure the effects of spatial R&D spillovers on firms' patent production at the city level. We use an original method to estimate the spatial dimension of spillovers using count data. The method, based on a generalized cross entropy approach, allows us to test spatial...

The purpose of this paper is to empirically investigate how regional advantages and firms characteristics influence the location of R&D. Looking at 2024 decisions of R&D lab location in France, we implement an extended conditional logit with spatially lagged explanatory variables to evaluate the...

It is well established that S-shaped curves describe the diffusion processes of many innovations quite well, but little insight on the mechanics of diffusion is achieved by simple curve fitting. We propose an evolutionary model of the diffusion process, focusing on the characteristics of...

Following modern innovation theory, this paper analyses in an evolutionary framework the impact of information network structures on firms' absorptive capacities and induced realization of technological progress (t.p.) in a finite set of firms. Main results of simulation analyses are: (i) At the...
