The project deals with the economic analysis of the use, provision and evolution of electronic business-to-business (B2B) markets. A B2B market is an interorganizational information system, which supplies participating buyers and seller companies with market information on prices and products and provides the possibility of economic interaction. In the center of the analysis is the application of theoretical findings from industrial organization and network economics theory to the area of electronic B2B markets. These do not only substantially contribute to the reduction of transaction costs but also change the competitive framework conditions of interacting enterprises. This is achieved by enabling e.g. collaborative platforms, information sharing or demand-side bundling as well as promoting the information transparency of participants. Furthermore, both the creation of new intermediates as well as strengthened disintermediation activities with associated market withdrawals are observable in the field of B2B. The focus of the project is to analyse these tendencies and characteristics together with their effects on allocation efficiency, market structures and competition from an economic point of view.
