Abstract Business-to-business (B2B) electronic commerce has become an important issue in the debate about electronic commerce. How should the intermediary charge suppliers and buyers to maximize profits from such a marketplace? We analyze a monopolistic B2B marketplace owned by an independent intermediary. The marketplace exhibits two-sided network effects where the value of the marketplace to buyers is dependent on the number of suppliers, and the value to suppliers is dependent on the number o

Later, incumbent companies (suppliers or buyers) came together to create iÌ

There are two popular forms of business-to-business (B2B) marketplaces: public marketplaces and private channels. We study why firms choose either or both of these sourcing channels. Using a framework of decision making under uncertainty, we explain firms' choice of B2B channels as a hedging strategy and as a method of obtaining greater managerial flexibility for the future. We show that greater uncertainty can lead to higher investment with firms more likely to invest in both public and private
