    Market Share Dynamics in a Model with Search and Word-of-Mouth Communication

    This paper analyzes price competition in an infinitely repeated duopoly game. In each period, consumers remember the existence and location of their previous supplier. New information is gathered via search or word-of-mouth communication. Market outcomes are history-dependent, and the Markov perfection refinement is used to narrow the set of equilibria. Firms are shown to use mixed pricing strategies in equilibrium. The resulting price dispersion generates non-trivial market share dynamics. The goal of the paper is to characterize these dynamics, and to reveal the driving forces behind them

    Modeling competition between two pharmaceutical drugs using innovation diffusion models

    The study of competition among brands in a common category is an interesting strategic issue for involved firms. Sales monitoring and prediction of competitors' performance represent relevant tools for management. In the pharmaceutical market, the diffusion of product knowledge plays a special role, different from the role it plays in other competing fields. This latent feature naturally affects the evolution of drugs' performances in terms of the number of packages sold. In this paper, we propose an innovation diffusion model that takes the spread of knowledge into account. We are motivated by the need of modeling competition of two antidiabetic drugs in the Italian market.Comment: Published at http://dx.doi.org/10.1214/15-AOAS868 in the Annals of Applied Statistics (http://www.imstat.org/aoas/) by the Institute of Mathematical Statistics (http://www.imstat.org

    The Effects of Imbalanced Competition on Demonstration Strategies

    Get PDF
    This paper analyzes the effect of competition on product demonstration decisions. Pre-purchase product demonstration enables marketers to differentiate products that are ex-post differentiated but are judged according to perceived fit, rather than actual fit, due to pre-purchase consumer uncertainty. Imbalanced competition accompanied by fit uncertainty motivates the follower to offer demonstrations to avoid a price war. This paper explores the conditions that lead the leader to retaliate. In addition to effects on quantity, competition may increase the quality of demonstrations offered by the leader. We analyze a business case, showing that competition may increase the demonstration intensity and that the leading manufacturer’s response to changes in competition is stronger than the responses of the followers. Our research has the potential to aid mangers in formulating demonstration strategies and in responding to competitors’ demonstration efforts.Imbalanced competition, product demonstration, differentiation, test-drive, price war, Political Economy, Production Economics,
