Abstract
Using concepts of neoinstitutional economics, such as transaction cost economics, institutional economics, property rights theory, and information economics, the development of the Open Source movement is investigated. Following the evolution of institutions in Open Source, it is discussed what the comparative institutional advantages of this model are. The conclusion is that it is the institutional framework of Open Source, not merely the low cost of Open Source software that makes it an attractive alternative mode of organizing the production and distribution of software and software-related services. Alternative organizations will be formed and existing organizations will be transformed to take advantage of its opportunities
