Conventional R&D-based growth theory suggests that productivitygrowth is positively correlated with population size or population growth,an implication which is hard to see in the data. Here we integrate R&D-basedgrowth into a unied growth setup with micro-founded fertility and...

Previous research on optimal R&D subsidies has focussed on the long run.This paper characterizes the optimal time path of R&D subsidization in a semi-endogenous growth model, by exploiting a recently developed numerical method.Starting from the steady state under current R&D subsidization in the...

This paper examines the relative contribution of openness and the R&D content of trade to TFP growth for North-South trade-related technology diffusion. The measure of foreign R&D used in the literature on trade-related technology diffusion imposes identical contributions of openness and the R&D...

The literature suggests that public research and development (R&D) subsidies mayreduce market failures affecting private R&D investment caused by incompleteappropriability of knowledge and financial constraints due capital marketimperfections. Drawing on the theory of investment under...

Recently, new game theoretic approaches have been suggested that address the emergence of inter-firm collaborative agreements (strategic alliances) that are situated between standard market transactions of unrelated companies and their integration by means of mergers and acquisitions. This...

We study the optimal R&D trajectory in a setting where new technologiesare never perfect backstops in the sense that there is no perfectlyclean technology that eventually solves the pollution problem once andfor all. New technologies have stings attached, i.e. each emits a specificstock...

An important discussion in recent years is the introduction of product patentsand the abolition of process patents. In a model with endogenous number of innovatingfirms, we show that whether product patent increases R&D is ambiguous, and depends onthe type of market demand and the cost of R&D....

We show the effect of patent protection on R&D investment in presence of‘inventing around’ (or imitation) and technology licensing...

We consider the effects of product market cooperation on R&Dinvestment, profits, consumer surplus and welfare. We show that though R&Dinvestment, consumer surplus and social welfare may be higher or lower underproduct market cooperation than product market competition, industry profit isalways...
