In markets where product quality is important, more than one characteristic is usually necessary to de fine product quality. Standard models maintain that: (i) in a duopoly there will be a quality leader no matter whether the product can incorporate one or two vertical attributes; (ii)...

We investigate the optimal R&D portfolio of a single-product monopolist investing in cost-reducing activities accompanied by efforts improving the quality of its product. There emerges that the firm's relative incentives along the two directions are conditional upon market affluency, measured by...

The optimal design of two-part tariffs is investigated in a dynamic model where two firms belonging to the same supply chain invest in R&D activities to increase the quality of the final product. It is shown that the replication of the vertically integrated monopolist's performance can be...

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...

We investigate the relationship between market concentration and industry innovative effort within a familiar two-stage model of R&D race in which firms compete à la Cournot in the product market. With the help of numerical simulations, we show that such a setting is rich enough to generate...

This paper offers an overview of the literature discussing oligopoly games in which polluting emissions are generated by the supply of goods requiring a natural resource as an input. An analytical summary of the main features of the interplay between pollution and resource extraction is then...

This paper examines the stability conditions of the equilibria in a market where profit-maximizing and CSR firms coexist in the presence of an environmental externality. An equilibrium in mixed duopoly is stable for low impact of productivity on pollution and high CSR sensitivity to consumer...

We adopt a stepwise approach to the analysis of a dynamic oligopoly game in which production makes use of a natural resource and pollutes the environment, starting with simple models where firms' output is not a function of the natural resource to end up with a full-fledged model in which (i)...
