Zaccour (2008) investigates the behaviour of a marketing channel where firms invest in advertising to increase brand equity, showing that an exogenous two-part tariff cannot be used to replicate the vertically integrated monopolist's performance. I revisit the same model proving the existence of...

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 mis- perception 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...

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

The model proposed in this paper investigates a differential Cournot oligopoly game with nonrenewable resource exploitation, in which each firm may exploit either its own private pool or a common pool jointly with the rivals. Firms use a deterministic technology to invest in exploration...

This paper investigates the impact of free trade on welfare in a two-country world modelled as an international Hotelling duopoly with quadratic transport costs and asymmetric countries, where a negative environmental externality is associated with the consumption of the good produced in the...

We modify the vertically differentiated duopoly model by André et al. (2009) replacing Bertrand with Cournot behaviour, and we characterise the region wherein a Porter-type result takes place. We show that the Porter hypothesis applies in an equilibrium taking always the form of a prisoner's...

We revisit Benchekroun (2008) to describe a differential oligopoly game of resource extraction under static, linear feedback and nonlinear feedback strategies, to show that (i) feedback rules entail resource exhaustion for a finite number of firms; and (ii) feedback strategies are more...

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...
