At this point, it is still unclear why and when customers prefer the ASP model over more traditional approaches. To make ASP more attractive, more knowledge about possible pricing and product strategies is needed. In this paper we describe different business models for ASP marketplaces. We first compare the cost structures of the classical licensing model with the new server-based approach. Then we illustrate how price and product differentiation may improve overall market efficiency. In particular, we show that by selling different software versions for different prices, ASP marketplaces may obtain near-optimal revenues with products that are relatively inexpensive, disaggregated, and customizable. Consumers can thus choose between a wide variety of product lines to fit their differing budgets and requirements.}, language = {en} } @article{GuentherTammLeymann2007, author = {G{\"u}nther, Oliver and Tamm, Gerrit and Leymann, Frank}, title = {Pricing web services}, series = {International Journal of Business Process Integration and Management (IJBPIM)}, volume = {2}, journal = {International Journal of Business Process Integration and Management (IJBPIM)}, number = {2}, url = {http://nbn-resolving.de/urn:nbn:de:0298-opus4-6511}, pages = {132 -- 140}, year = {2007}, abstract = {This paper focuses on the challenges associated with composing and pricing web services. We present the results of an online experiment, where subjects were confronted with a variety of choices and decisions relating to web service markets and service composition. Our analysis shows that people expect the price of a composite web service to be lower than the sum of the prices of the elementary services, that is, users are not willing to pay for aggregation by a third party. To obtain a viable business model for composite web services, non-standard pricing mechanisms, such as auctions and negotiations, possibly supported by electronic agents, have to be taken into consideration. Usage-based pricing schemes, combined with an option to switch to a flat subscription, seem most appropriate to penetrate the developing market for web services.}, language = {en} }
