The Jones R&D Growth Model: Comment on Stability
No full textThe dynamics of most prominent endogenous growth models are well understood. One notable exception is the Jones (1995) R&D growth model. This paper provides an analytical treatment of this model's transitional dynamics. It is shown that, given constant returns to labor in R&D (as conventionally assumed in R\&D growth models), a unique trajectory converging to the balanced growth path exists. The equilibrium growth path can be monotonic or oscillatory. Moreover, applying a theorem from Arnold (2004), this result can be used to characterize the dynamic behavior of the multi-country open-economy version of the model. Von den meisten wichtigen Modellen endogenen Wachstums ist das dynamische Verhalten abschließend untersucht und wohlbekannt. Eine wichtige Ausnahme ist das Jones- (1995) F&E-Wachstumsmodell. In diesem Paper wird gezeigt, dass unter der üblichen Annahme konstanter Grenzerträge von Arbeit in F&E ein eindeutiger Wachstumspfad existiert, der die Jones-Ökonomie in ihr stationäres Gleichgewicht führt. Dieser Gleichgewichtspfad kann monoton sein oder gedämpft oszillieren. Durch die Anwendung eines Theorems aus einer verwandten Arbeit folgt darüber hinaus, dass dieses Stabilitätsergebnis auch auf die Mehr-Länder-Version des Jones-Modells übertragen werden kann.Endogenes Wirtschaftswachstum ; Dynamische Stabilität; ; endogenous growth ; stability
"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.

Theoretical frameworks for the learning of geometrical reasoning
No full textWith the growth in interest in geometrical ideas it is important to be clear about the nature of geometrical reasoning and how it develops. This paper provides an overview of three theoretical frameworks for the learning of geometrical reasoning: the van Hiele model of thinking in geometry, Fischbein’s theory of figural concepts, and Duval’s cognitive model of geometrical reasoning. Each of these frameworks provides theoretical resources to support research into the development of geometrical reasoning in students and related aspects of visualisation and construction. This overview concludes that much research about the deep process of the development and the learning of visualisation and reasoning is still needed
Connecting Research with Communities through Performative Social Science
No full textA pioneer in Performative Social Science, Kip Jones makes a case for the potential of arts-based social science to reach audiences and engage communities. Jones contextualises both the use of the arts in Social Science, as well as the utility of Social Science in the Arts and Humanities. The discussion turns next to examples from his own work and what happens when Art talks to Social Science and Social Science responds to Art. The benefits of such interaction and interdisciplinarity are outlined in relation to a recently completed project using multi-methods, which resulted in the production of a professional short film. In conclusion, Performative Social Science is redefined in terms of synthesis that can break down old boundaries, open up channels of communication and empower communities through engagement

Estimating the Dynamics of R&D-based Growth Models
No full textSeveral R&D-based models of endogenous economic growth are investigated under the Solow-like assumption of fixed allocation of resources across activities. We identify model parameters that lead to explosive dynamics and analyse various economic techniques to avoid it. The techniques include adding stricter constraints on model trajectories and limiting factors in technology equation. In particular, we demonstrate that our vintage version of the well-known R&D-based model of economic growth (Jones, 1955) exhibits the same balanced dynamics as the original modelVintage capital models, Endogenous technological change, R&D investment, Explosive dynamics, Nonlinear Volterra integral equations
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
