The virtual value chain, created by John Sviokla and Jeffrey Rayport, [8] is a business model describing the dissemination of value-generating information services throughout an Extended Enterprise. This value chain begins with the content supplied by the provider, which is then distributed and supported by the information infrastructure ...
The idea of GVCs did not have a single source. While there are connections to the notions of “commodity chain” introduced by Immanuel Wallerstein and “value chain” analyzed by Michael Porter, the GVC framework included distinctive elements that differentiated it from previous paradigms. The emphasis on the power of lead firms in global ...
Rayport and Sviokla did not present a formal definition of marketspace in their original Harvard Business Review paper but describe its characteristics. In synthesis marketspace is an information-defined transaction space where value is created and extracted. It exists in parallel to physical marketplaces and marketplace transactions.

Global value chains are a network of production and trade across countries. The study of global value chains requires inevitably a trade theory that can treat input trade. However, mainstream trade theories (Heckshcer-Ohlin-Samuelson model and New trade theory and New new trade theory) are only concerned with final goods.
Value network analysis (VNA) is a methodology for understanding, using, visualizing, optimizing internal and external value networks and complex economic ecosystems. [ 1 ] [ 2 ] The methods include visualizing sets of relationships from a dynamic whole systems perspective.
In auction theory, particularly Bayesian-optimal mechanism design, a virtual valuation of an agent is a function that measures the surplus that can be extracted from that agent. A typical application is a seller who wants to sell an item to a potential buyer and wants to decide on the optimal price.
