In a two-stage R&D game of process innovation, we investigate the effect of exogenously changing R&D spillovers and market concentration on the equilibrium level of effective cost reduction, total output, profits and social welfare. Interpreting spillover as a measure of patent protection, we...

There is evidence that competing firms outsource R&D to the same independent for-profit laboratory. We draw on this stylized fact to construct a model where two firms in the same industry offer transfer payments in exchange for user-specific R&D services from a common laboratory. Inter-firm and...

We outline the conditions for efficient entry order and clustering in a triopoly preemption game in which firms differ in their sunk costs of entry. The critical factor turns out to be how symmetric the potential entrants are. If the cost asymmetry between the firms is sufficiently large, entry...

We analyse economic welfare in R&D intensive industries under varying assumptions on the spillover process. The focus lies on spillover processes with complementary R&D investments such as those modelling absorptive capacity. There spillovers give rise to both negative and positive...

This paper develops a three stage oligopoly game for R&D cooperation, R&D expenditure and product market competition. In the first stage, firms decide whether or not to conduct R&D in cooperation with other firms. In the second stage the level of R&D investment is determined. Finally, firms...

This paper introduces a second, vertically related industry into the usual one-industry oligopoly framework of cooperative R&D investment between firms operating on the same product market. R&D efforts are affected by intra- and inter-industry R&D spillovers. Horizontal and vertical R&D...

The paper investigates firms’ behavior and outcomes (levels of cost-reducing R&D, output, profit and welfare in equilibrium) in a differentiated duopoly with process innovation. One of the important features in this paper is that spillovers operate in the R&D stage and are tied to the degree...

This paper investigates firms' optimal location choices explicitly accounting for the role of inwards and outwards knowledge spillovers in a dynamic Cournot oligopoly with firms that are heterogeneous in their ability to carry out cost-reducing R&D. Firms can either locate in an industrial...

This paper examines R&D tax incentives in oligopolistic markets. We characterize the conditions under which tax incentives reach the socially desirable level of firm-financed R&D spending. The outcome of the market depends not only on the level of technological spillover in the industry but also...

The objective of this article is to investigate the impact of research and development (R&D) spillovers on cartelization of industries characterized by differentiated products. For simplicity, we focus on the duopoly market in which firms compete according to the Stackelberg leadership model....
