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...

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....

Innovations in consumer products frequently rely on technological advances across multiple tiers in a supply chain. Considering the consumer market demand and downstream investment conditions as input, we model a game in a two-tier supply chain where downstream firms choose to adopt different...

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 analyze firms' decisions to adopt a vertical integrated or decentralized structure taking into account the characteristics of both the final good competition and the R&D process. We consider two vertical chains, where R&D is conducted by upstream sectors. R&D investment determines the...

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 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...

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...
