We construct an asymmetri c duopolistic R&D and production behavior model subject to knowledge spillovers. This model is an extension to the symmetric model of d'Aspremont and Jacquemin (A&J (1988)) and aims to determine the cooperative and non-cooperative R&D strategies for two agents of...

We present a model where firms make competitive decisions about the optimal duration (or time to build) of their R&D projects. Choosing its project's duration, the firm can choose to become a leader or a follower, based on its R&D efficiency, the size of the R&D to be carried out and the degree...

This paper presents a study of backward and forward patent citations in patents granted to firms and institutions in the Netherlands by the United States Patent and Trademark Office (USPTO). The study establishes different patterns of patent citation in recent Dutch patents belonging to...

This paper investigates two major issues of the patenting behavior of Belgian firms. Firstly, it studies the probabilistic distribution of the patent citations among several major sectors. Secondly, the firm-oriented data is studied to investigate the relationships between the Belgian firms size...

This paper conducts a comprehensive study of patent citations in patents granted to Belgian corporate applicants by the United States and the European Patent Offices using qualitative response variable analysis. The analysis uncovered different patterns of citations in patents, which belong to...

This paper presents a dynamic model of a competitive R&D and production duopoly subject to knowledge spillovers. Two asymmetric firms operate for a limited period of time and dispose their knowledge capital in the end. Both firms and the social planner prefer the R&Dcooperative strategy over the...
