    This paper empirically investigates the determinants of R&D diversification strategies in the drug industry. It enriches the existing literature by proposing to look at diversification factors, which reflect market and technological proximity of an R&D project towards other projects within a firm's portfolio as well as R&D competition factors. Additionally, the characteristics of R&D in the market where a new potential product is developed affect future product choice. The analysis is performed for products-in-development data, merged with firms' patents, which allows us to separate project proximity in market niches from technological proximity. The results of empirical estimation support an idea that R&D diversification is governed by the economies of scope as well as the escape competition motive. Moreover, it is found that competition rather than spillovers in the niche where an R&D project is developed defines firms' decisions to diversify. -- diversification ; technological diversity ; relatedness ; competition ; R&D

    This paper aims to investigate the effect of knowledge characteristics on the total factor productivity of firms developing drugs in the pharmaceutical industry. We decompose knowledge into knowledge associated with the technological firm portfolio and knowledge related to R&D projects, which represent drug development at the clinical testing stage. The latter is attributed to the knowledge of relevant markets where the drugs will be sold. The results show that the effect of technological coherence vs. market coherence and of accumulated knowledge on the productivity of firms differs. Productivity increases with the number of patents and decreases with the patent diversity and project portfolio coherence. When considering only the project knowledge, the diversity of the project portfolio positively affects productivity. -- total factor productivity ; diversity ; coherence ; knowledge

    This paper investigates the determinants of success in the development of new drugs. In specific, it explores the factors of success in drug development programs at different stages of innovation process. We use economies of scale, scope, R&D competition and technological spillovers as explanatory variables and test whether the effect of these variables on the success of a project differs in relation to the discovery and development stages of innovation, respectively. Our main finding is that spillovers, including spillovers from collaboration, are important in explaining the success of projects during the discovery stage of innovation, while in the later development stage, the effects of competition outweigh any benefits from spillovers. -- economies of scale and scope ; spillovers ; competition ; R&D ; innovation process

    In this paper we focus on proximity as one of the main determinants of international collaboration in pharmaceutical research. We use various count data specifications of the gravity model to estimate the intensity of collaboration between pairs of countries as explained by the geographical, cognitive, institutional, social, and cultural dimensions of proximity. Our results suggest that geographical distance has a significant negative relation to the collaboration intensity between countries. The amount of previous collaborations, as a proxy for social proximity, is positively related to the number of cross-country collaborations. We do not find robust significant associations between cognitive proximity or institutional proximity with the intensity of international research collaboration. Moreover, there is no robust and significant relation between the interaction terms of geographical distance with social, cognitive, or institutional proximity, and international research collaboration. Our findings for cultural proximity do not allow of unambiguous conclusions concerning their influence on the collaboration intensity between countries. Linguistic ties among countries are associated with a higher amount of cross-country research collaboration but we find no clear association for historical and colonial linkages. -- International Cooperation ; Pharmaceuticals ; Proximity
