چکیده

In this paper, we explore the effects of the introduction of localised externalities through interaction structures upon local and global properties of the simplest market model: the discrete choice model with a single homogeneous product and a single seller (monopoly). Following Kirman, the resulting market is viewed as a complex interactive system. We use an ACE (Agent based Computational Economics) approach to investigate the market mechanisms and underline in what way the knowledge of generic properties of complex adaptive system dynamics can enhance our perception of the market mechanism in the numerous cases where individual decisions are inter-related. Résumé Dans ce papier, nous explorons les effets de l’introduction d’externalités transmises par des structures d’interactions sur les propriétés locales et globales du plus simple modèle de marché : choix discret, produit homogène, monopole. A la suite de Kirman, le marché ainsi décrit peut être considéré comme un système complexe interactif. Nous utilisons une approche multi-agents (ACE) pour explorer les mécanismes de marché et monter de quelle manière les propriétés génériques des systèmes complexes adaptatifs peuvent améliorer notre perception des phénomènes de marchés lorsque les choix des agents sont interdépendants. 10e Rencontre Internationale ACSEG (Approches Connexionnistes en Sciences Economiques et de Gestion) Université de Nantes, 20 et 21 novembre 2003

Versioning information goods with network externalities

Positive externalities characterize the consumption of a majority class of information goods and services such as software, e-mail, and online content and services including virtual communities. We show that network externality is critical for the market segmentation and product line decisions of an information goods seller. With externality, a monopoly of multiple existing products offers exac...

Impact of Network Externality in the Security Software Market∗

The market for security software has witnessed an unprecedented growth in recent years. A closer examination of this market reveals certain idiosyncrasies that are not observed in a traditional software market. For example, it is a highly competitive market involving several major vendors, often with a very aggressive pricing strategy adopted by new entrants. Yet, the market coverage seems to b...

Market Segmentation for Information Goods with Network Externality: a Note

Positive externalities characterize the consumption of a majority of information goods such as software and online content services including virtual communities. We show that network externality is critical for the market segmentation and product line structure of such information goods. A monopoly of multiple existing products offers exactly two distinct qualities. Essential for such a limite...

Network Platform Competition in a Two-Sided Market: Implications to the Net Neutrality Issue

We consider a model for network platform competition between the current “Best Effort” (BE) network and a hypothetical “Next Generation Network” (NGN). We suppose there are indirect network externalities between content providers (CPs) and users of each platform. Moreover, we suppose that NGN users can access BE content, thus there is a cross-platform, indirect network externality. This feature...

Small Worlds and Phase Transition in Agent Based Models with Binary Choices

This paper reviews some aspects of complex collective behaviour in an agent-based framework. It examines the effects of interaction structures (lattices, small worlds) on dynamic properties of simple binary choices models. When individual actions become interdependent, complex dynamics may arise. In order to illustrate such a phenomenon, a very simple evolutionary game is presented, using a spa...
