    Abstract: We analyze the distributions of paper-paper and paper-patent citations and estimate the relationship between them, based on a sample of 4,763 published papers for which the corresponding authors were among the top 100 researchers in the life and medical sciences in Japan. We find that paper-paper citations peak at an average of 4 years after the publication of a paper, while the corresponding lag for paper-patent citations is 6 years. Although there is a time lag before papers can be put to practical use, this lag has shortened in recent years. Moreover, the quality of a paper is important for being cited by a patent, and a paper’s quality increases the number of paper-patent citations. In addition, we show that an inverse U-shaped relationship exists between the amount of research grant funding and research quality, and we can derive the efficient amount of research grant funding that maximizes research quality. We find that the relationship between research quality and the total number of papers written by the researcher(s) is U-shaped, and we derive the number of papers that minimizes research quality

    Abstract: This paper exploits longitudinal data on firm performance and patenting activity for 23 OECD countries over the period 2003-2010 to explore the extent to which changes in the patent stock are associated with flows of capital and labour to patenting firms. While the finding that patenting is associated with real changes in economic activity at the firm level is in line with recent literature, new empirical evidence presented suggests that the impact of patenting on firm size is likely to be causal. Moreover, these data reveal important differences across OECD countries in the extent to which innovative firms can attract the complementary tangible resources that are required to implement and commercialise new ideas. In turn, the contribution of framework policies to explaining the observed cross-country differences in the magnitude of these flows is explored. While further research is required to establish causality, the results are consistent with the idea that well-functioning product, labour and capital markets; efficient judicial systems and bankruptcy laws that do not overly penalise failure can raise the returns to innovative activity. The paper also investigates the heterogeneous impacts of policies and finds that young firms – which are more likely to experiment with disruptive technologies and rely on external financing to implement and commercialise their ideas – disproportionately benefit from reforms to labour markets and more developed markets for credit and seed and early stage finance. Les ressources convergent-elles vers les entreprises brevetantes ? : Éléments de comparaison entre pays à partir de données au niveau des entreprises Cette étude tire parti de données longitudinales sur les performances et l’activité de brevetage d’entreprises de 23 pays membres de l’OCDE sur la période 2003-2010 pour examiner dans quelle mesure des évolutions du stock de brevets sont associées à des flux de capitaux et de main-d’oeuvre en direction des entreprises brevetantes. Si l’observation que le brevetage est associé à des évolutions réelles de l’activité économique au niveau de l’entreprise concorde avec les publications récentes, les nouvelles observations empiriques présentées ici donnent à penser qu’il existe vraisemblablement un lien de causalité entre le dépôt de brevets et la taille de l’entreprise. De plus, ces données font apparaître d’importantes différences entre pays de l’OCDE quant à la mesure dans laquelle les entreprises innovantes peuvent attirer les ressources corporelles complémentaires requises pour mettre en oeuvre et commercialiser des idées nouvelles. L’étude explore ensuite la contribution de politiques cadres qui pourrait expliquer les différences observées entre pays dans l’ampleur de ces flux. Bien que des recherches complémentaires soient nécessaires pour établir une causalité, les résultats concordent avec l’idée que des marchés de produits, de main-d’oeuvre et de capitaux efficaces, des systèmes judiciaires efficients et des législations sur les faillites qui ne pénalisent pas indûment l’échec peuvent accroître les retours sur l’activité d’innovation. L’étude examine aussi les impacts hétérogènes des politiques et constate que les jeunes entreprises – qui sont davantage susceptibles d’expérimenter des technologies de rupture et de dépendre de financements externes pour la mise en oeuvre et la commercialisation de leurs idées – bénéficient beaucoup plus que les autres des réformes des marchés du travail et de marchés plus développés du crédit et du financement des phases d’amorçage et de démarrage.
