A Fees System of an Innovative Group-Trading Model on the Internet

摘要

A new Core Broking Model (CBM) has been introduced to e-markets, involving joint-selling of multiple goods and offering volume discount for group-buying coalitions. It is a core-based model, maintaining the stability of coalitions and using physical brokers to resolve group-trading problems in e-markets. After a survey has been made on the present commission of brokers and the current fees systems of some popular e-marketplaces, a fees system for the CBM has been set up and was suggested to the model. The fees system consists of four kinds of fees: final value fee, handling fee, session fee and online store fee. It is evaluated and discussed at the end of this paper.
