We revisit the study of the dynamics of a duopoly game à la Bertrand with horizontal product differentiation and bounded rational firms analysed by Zhang et al. (2009), (Zhang, J., Da, Q., Wang, Y., 2009. The dynamics of Bertrand model with bounded rationality. Chaos, Solitons and Fractals 39,...

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...

This paper considers price competition in a duopoly with quality uncertainty. The established firm (the `incumbent') offers a quality that is publicly known; the other firm (the `entrant') offers a new good whose quality is not known by some consumers. The incumbent is fully informed about the...

We construct a model to show that outsourcing of a crucial input can occur even though it can be produced in-house at a lower cost. There are two firms producing differentiated goods and competing in prices, and only one of them possesses input production technology which is superior to that of...

This paper develops a model of successive oligopolies with endogenous market entry, allowing for varying degrees of product differentiation and entry costs in both markets. Our analysis shows that the downstream conditions dominate the overall profitability of the two-tier structure while the...

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...

This paper studies market competition when firms can influence consumers' ability to compare market alternatives, through their choice of price "formats". We introduce random graphs as a tool for modelling limited comparability of formats. Our main results concern the interaction between firms'...

The purpose of this paper is to investigate how socially concerned consumers' preferences affects firms' decisions to commit to social responsibility. In a market in which firms face the same demand function and products are homogeneous, we find that a large group of socially concerned consumers...

This paper proposes a model in which identical sellers of a homogenous product compete in both prices and price frames (i.e., ways to present price information). We model price framing by assuming that firms’ frame choices affect the comparability of their price offers: consumers may fail to...
