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 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 model a vertically differentiated duopoly with quantity-setting firms as an extended game in which firms noncooperatively choose the timing of moves at the quality stage, to show that at the subgame, perfect equilibrium sequential play obtains, with the low-quality firm taking the leader’s...

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...

We investigate the introduction of a minimum quality standard in a vertically differentiated duopoly where production is polluting. We examine the alternative frameworks with quality-dependent fixed or variable costs, under both price and quantity competition. Under Bertrand behaviour, the...

We propose an explanation for this apparent puzzle by exploiting Dastidar's approach, which delivers a...</p>

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...

We present a theoretical framework in which an elitist and a non-elitist university in a developed country compete by choosing their admission standards and deciding whether or not to open a branch campus in a developing country. Students from a developing country attend university if either a...

In the last few years the superstar phenomenon has found wide circulation, thus increasing the number of people who earn massive incomes thanks to their work. The main aim of this article is to examine the various hypotheses advanced to explain the phenomenon: they can be identified with three...
