The authors modify the price-setting version of the vertically differentiated duopoly model by Aoki (Effect of Credible Quality Investment with Bertrand and Cournot Competition, 2003) by introducing an extended game in which firms noncooperatively choose the timing of moves at the quality stage....

We examine the relationship between competition and innovation in an industry where production is polluting and R&D aims to reduce emissions ("green" innovation). We present an n-firm oligopoly where firms compete in quantities and decide their investment in "green" R&D. When environmental...

The choice between quantity and price in order to stabilize collusion is modeled here. It is shown that this relocates the prisoners’ dilemma backwards, from the market stage to the stage where the market variable is chosen in order to sustain collusion, and where discount rates appear as the...

We characterize the interplay between firms’ decision in terms of product differentiation and the nature of their ensuing market behaviour. We prove the existence of a non-monotone relationship between firms’ decision at the development stage and their intertemporal preferences.

The authors characterize the interplay between firms' decisions in terms of either horizontal or vertical product differentiation and their ensuing price behavior, be that collusive or not. They prove the existence of a non-monotone relationship between firms' decisions at the development stage...

This paper tackles the issue of choosing roles in duopoly games. First, it is shown that the two necessary (and sufficient, if both satisfied) conditions for sequential play to emerge at equilibrium are that both leader and follower are at least weakly better off than under simultaneous play....

We investigate a linear state differential game describing an asymmetric Cournot duo- poly with capacity accumulation à la Ramsey and a negative environmental externality (pollution), in which one of the firms has adopted corporate social responsibility (CSR) in its statute, and therefore...

In this paper we analyse a setup where consumers are heterogeneous in the perception of environmental quality. The equilibrium is verified in a setting with horizontal and vertical (green) differentiation. Profits are increasing in the misper- ception of quality, while, the investment in green...

In recent years Open Innovation (OI) processes have been receiving growing attention from the empirical and theoretical economic literature, where a debate is taking place on the aspects of complementarity or substitutability between internal R&D and OI spillover. By means of a differential game...
