    Abstract: This paper investigates the effect of patenting on follow-on knowledge in cancer research. Using a difference-in-difference approach on an original dataset of patent-paper-pairs we are able to estimate the causal effect of the granting of a patent on scientic development in the same domain. Furthermore, we disentangle between private companies and universities in order to assess whether patenting impacts differently on the two groups. In addition, we study to which extend the degree of applicability of an innovation is further affects the relation. To address these issues we build a novel dataset matching patent data (retrieved from USPTO) and publication data (retrieved from Thompson-Web of Science). Results show that patenting reduces the rate of citations of the paired publication indicating a decrease of related scientic activity only in case the citing agent belongs to a public institution. In addition, the the more invention is applied, the weaker is the negative effect. This paper makes a contribution to the debate on IPR and economics of science.

    Abstract: This paper examines the rise of China's relative standing in the global academic science marketplace. We first develop a simple theoretical model, based on the aggregation of individual knowledge production functions. This model predicts the existence of a stable power (scaling) law, relating the world share of countries' scientific production to their world share of public investment in scientific research. We test and confirm this prediction, using bibliometric crosscountry longitudinal data for OECD and non-OECD countries, over the 1996-2015 period. This analysis allows for China's impressive catch-up, and for the West's decline to be accounted for, in the science marketplace, over the last two decades.
    Abstract: Cet article analyse la montée en puissance de la Chine et l'évolution de sa place relative sur le marché scientifique mondial. Tout d'abord, nous développons un modèle théorique simple basé sur l'agrégation de fonctions de production de savoir individuelles. Ce modèle prédit l'existence d'une loi de puissance stable entre la part d'un pays dans les publications scientifiques mondiales et sa part dans les investissements de recherche publique mondiaux. Nous testons et confirmons ces prédictions en utilisant des données bibliométriques et des bases de données de l'OCDE sur l'investissement des pays dans la recherche publique. Ces données portent sur la période 1996-2015. Cette analyse permet de rendre compte de l'impressionnant rattrapage de la Chine et du déclin relatif des pays occidentaux sur le marché scientifique mondial, survenus durant les deux dernières décennies.
