"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.

An Agent-Based Spatially Explicit Epidemiological Model in MASON
No full textThis paper outlines the design and implementation of an agent-based epidemiological simulation system. The system was implemented in the MASON toolkit, a set of Java-based agent-simulation libraries. This epidemiological simulation system is robust and extensible for multiple applications, including classroom demonstrations of many types of epidemics and detailed numerical experimentation on a particular disease. The application has been made available as an applet on the MASON web site, and as source code on the author\'s web site.Epidemiology, Social Networks, Agent-Based Simulation, MASON Toolkit
The R&D Tax Incentives
No full textThis article sets out some background information and reflections of the author on the R&D tax incentive schemes included in the Common Corporate Tax Base (CCTB) Proposal. In particular the author analyzes the stimulus to private R&D through ad hoc tax incentives included in the CCTB Proposal and dives into the actual provisions included in the Proposal highlighting the most relevant issues connected with their design and interpretation. Moreover, the author explores the interaction between the CCTB Proposal and the granting by Member States of domestic R&D tax incentives

Using strategic ambiguity as management practice in academic R&D : An ethnographic study of MIT SENSEable City Lab
No full textThis article explores the role of strategic ambiguity (Eisenberg, 2007; March & Olsen, 1976) as a management practice, as used in SENSEable City Lab - a R&D-oriented lab located at the Massachusetts Institute of Technology in Cambridge, MA.
Although literature has already explored strategic ambiguity in various organizational settings, studies focusing on how academic institutions use strategic ambiguity in the context of R&D are quite sparse.
The article aims at filling this gap by reporting on a study conducted by the author across 2011 and 2014 in a R&D-oriented academic lab and reflecting on the potential of strategic ambiguity as an effective dialogic strategy to appreciate differences among internal organization members and with external partners. The article also examines some shortcomings of strategic ambiguity, such as the level of anxiety reported by some members of the lab
Preemptive Search and R&D Clustering Revisited
No full textThe results obtained by Cardon and Sasaki (1998) on R&D clustering are derived under the specific assumption that firms only can own one patent. When multiple patents are allowed, R&D clustering will come about more frequently if search costs are substantial.R&D clustering; persistence of monopoly
R&D and Market Value: Appropriability vs. Preemption
No full textThe recent empirical studies on innovation and market value suggest that R&D has a strong complementarity with market share in the market valuation of firms. Blundell, Griffith and Reenen (1999) argue that it represents the strategic preemptive effect, while Hall and Vopel (1997) suggest a Schumpeterian reason (the cost of financing R&D is lower for large firms). The theoretical framework of these studies is the classical work by Griliches (1981), which postulates that the market value of firm is given by the sum of the values of physical capital and R&D capital with respective multipliers. However, non-rivalry in using new knowledge within a firm makes this framework highly questionable. This paper examines the nexus between R&D and market value, based on a simple but new structural model. Major findings are the following. First, the new model shows that the market evaluation of R&D may well be high for a firm with a large market share, simply due to its appropriability advantage. Second, our estimation based on the data of the Japanese firms shows that the new specification performs better. Third, it shows that there is no statistical support for the prevalence of preemption effect.R&D, market value, appropriability, preemption
Measuring the Returns to R&D
No full textWe review the econometric literature on measuring the returns to R&D. The theoretical frameworks that have been used are outlined, followed by an extensive discussion of measurement and econometric issues that arise when estimating the models. We then provide a series of tables summarizing the major results that have been obtained and conclude with a presentation of R&D spillover returns measurement. In general, the private returns to R&D are strongly positive and somewhat higher than those for ordinary capital, while the social returns are even higher, although variable and imprecisely measured in many cases. Nous faisons un survol de la littérature économétrique qui mesure les rendements de la recherche-développement. Nous esquissons les modèles théoriques sousjacents et nous discutons en détail les problèmes de mesure et d’économétrie qui se posent quand il s’agit d’estimer ces modèles. Ensuite, nous présentons une série de tableaux qui résument les principaux résultats qui ont été obtenus et nous finissons par une discussion des mesures d’externalité de la recherche. En général, les rendements privés de la recherche sont positifs et légèrement plus élevés que ceux de l’investissement en capital physique et les taux de rendement sociaux de la R-D sont encore plus élevés, mais fragiles et imprécis.returns to R&D, innovation, social returns, spillovers, rendements de la R&D, innovation, rendements sociaux, externalités
