Abstract: | Electronic communities can be designed to organize consumers, to pool their purchasing power, and to guide their purchasing
decisions. Such commercial electronic communities have the potential to facilitate the creation of novel marketplaces, and
even radically change the buyer-seller interaction, as physical communities did throughout the history. Commercial electronic
communities are groups of consumers that participate in the marketplace as a single unit. In addition to bargaining power
gained from such bundling, such communities can expand markets by reducing market uncertainty, and they have the potential
to drastically reduce consumers’ transaction costs, by facilitating group transactions and bulk purchasing. Communities are
characterized by their size, their pricing strategy, and their membership characteristics. Analytical models and numeric analysis
is utilized to compute the optimum size of a community for given market characteristics. Two major community pricing strategies
are analyzed to improve the community design, and the conditions are derived where one dominates the other. Finally, market
segmentation techniques are introduced to control the membership characteristics of the community to further improve the design.
