This paper considers cost-reducing R&D investment with spillovers in a Cournot oligopoly
with overlapping ownership. We show that overlapping ownership leads to internalization of …

I analyze the effects of competition on process innovation and product introduction and
obtain robust results that hold for a range of market structures and competition modes. It is …

This paper reports a search for general tendencies among models that look at spillovers in
innovative activities. A number of inferences are detailed that appeared in a wide class of …

We provide an extensive comparison of the well-known R&D models of d'Aspremont-
Jacquemin and Kamien-Muller-Zang, exposing full or partial conflict in key conclusions and …

This paper compares Bertrand and Cournot equilibria in a differentiated duopoly with
substitute goods and product R&D. I find that R&D expenditure, prices and firms' net profits …

Key findings of game–theoretic models that describe the effects of spillovers, market size,
research productivity and the generality of a firms' research approach on innovation efforts …

This paper deals with a general version of a two-stage model of R&D and product market
competition. We provide a thorough generalization of previous results on the comparative …

We investigate the determinants of firms' choices between different modes of vertical
cooperation for innovation. Based on survey data on German innovating firms, we state that …

Previous literature has shown that manufacturers' choices between radical and incremental
green innovation modes can greatly impact the tradeoff between industry growth and carbon …

We investigate dynamic R&D for process innovation in a Cournot duopoly where firms may
either undertake independent ventures or form a cartel for cost-reducing R&D investments …
