We consider cannibalization in a duopoly model in which …rms with di¤erent costs supply two vertically di¤erentiated products in the same market. We …nd that an increase in the di¤erence in quality between the two goods or a decrease in the marginal cost of the high-quality goods leads to...

This paper analyzes the impact of risk and ambiguity aversion - Knightian uncertainty - on the choice of optimal quality and timing of market entry. Irreversibility of the investment in product development is introduced in a continuous-time stochastic model applying the real option literature....

In this paper, we consider a duopoly model where two firms sell two differentiated products and there is a network externality between either carriers or machines. We derive the equilibria of these games and illustrate the effects of a change in quality on the equilibrium quantity of each good....

We consider cannibalization in a duopoly model in which firms with diffrent costs supply two vertically differentiated products in the same market. We find that an increase in the difference in quality between the two goods or a decrease in the marginal cost of the high-quality goods leads to...

In this paper, we consider and propose a new duopoly model of cannibalization in which firms produce and sell two vertically differentiated products in the same market. We show that each firm produces the high-quality good more (less) than the low-quality good if the upper limit of taste of...

In a real oligopoly, firms often supply multiple products differentiated by quality in the same market. To examine why they do so, we consider a duopoly model in which firms can choose between supplying two vertically differentiated products and selling a single product in the same market. By...

We adopt a framework of vertical differentiation (i.e. differentiation by quality) to study the issue of Corporate Social Responsibility (CSR). We develop a model of duopoly in a two‐country setting, in which firms choose the country of location, the level of CSR and finally compete in the...

In a Bertrand duopoly model, we study firms’ eco-labeling behavior when certification process imperfectly signals environmental product quality to consumers. The test is noisy in the sense that brown products may be labeled while green products may not. We study how strategic interaction...

We study a two-stage duopoly game, where, at the first stage, firms choose if adopting or not a social responsibility label. The firm who adopts the social responsibility label (the ethical firm) has high marginal costs, while the firm who doesn’t adopt it (the standard firm), supports low...

We study the local stability properties of a duopoly game with price competition, different product quality and heterogeneous expectations. We show that the Nash equilibrium can loose stability through a flip bifurcation when the consumer’s type range increases. This result occurs irrespective...
