An Overview of Information Goods Pricing

[[abstract]]Although information economy has been the focus of considerable research, no unified and exhaustive classification model for current pricing methods exists. This work presents a novel unifying pricing framework. Each category in the framework is defined by the structural elements that accounts for its behaviour and particular aims. This work also identifies the implicit joints among categories as the basis for optimising prices (only in terms of different perspectives). The benefits of the unifying framework are that it provides a conceptual abstract model that differentiates between different pricing methods, and positions the future effectual pricing methods.[[journaltype]]國

A Decision Procedure for Bundle Purchasing with Incomplete Information on Future Prices

This paper introduces the on-line bundle-purchasing problem (OBPP) as a new computational challenge induced by e-commerce technology. The task of the OBPP is to decide which of many satisfactory combinations (bundles) of items should be purchased, from whom, and when, to maximize the buyer's overall satisfaction. Satisfaction, formalized as multi-attribute utility, includes attitudes toward quality, reputation, and risk. The Prequote-Quote-Rescind (PQR) protocol communicates probabilistic and temporal information on the future prices and availabilities of items. A comparison set, defined as a set of bundles in which all items are available for a fixed interval and their prices are known, determines future intervals when purchase decisions will be fully informed. A decision procedure is provided that makes effective use of comparison sets and improves a buyer's expected utility compared with a naive decision procedure.Les auteurs de cet article d\ue9crivent le regroupement des achats en ligne (on-line bundle-purchasing problem - OBPP) comme le nouveau probl\ue8me informatique que pose la technologie du commerce \ue9lectronique. La fonction du regroupement des achats en ligne est de d\ue9terminer laquelle des nombreuses combinaisons (groupes) de produits satisfaisantes doit-on acheter, \ue0 quel endroit et \ue0 quel moment, afin de maximiser la satisfaction globale de l'acheteur. La satisfaction, d\ue9finie formellement comme l'utilit\ue9 multi-dimensionnelle, englobe les attitudes \ue0 l'\ue9gard de la qualit\ue9, de la r\ue9putation et du risque. Le protocole PQR (Prequote-Quote-Rescind) sert \ue0 communiquer de l'information probabiliste et temporelle sur les prix futurs et la disponibilit\ue9 des produits. l'ensemble de comparaison, qui est d\ue9fini comme un ensemble de groupes de produits o\uf9 tous les produits sont disponibles pendant une p\ue9riode d\ue9termin\ue9e et leurs prix connus, sert \ue0 d\ue9terminer les p\ue9riodes futures o\uf9 les d\ue9cisions d'achat seront prises en toute connaissance de cause. Les auteurs d\ue9crivent une proc\ue9dure de d\ue9cision qui utilise efficacement les ensembles de comparaison et qui aboutit \ue0 une esp\ue9rance d'utilit\ue9 de l'acheteur plus grande qu'une proc\ue9dure de d\ue9cision \ue9l\ue9mentaire.NRC publication: Ye
