        bibo:abstract             "Network effects ubiquitous with information goods (content, software) are a phenomenon being discussed  more and more recently. Despite strong empirical support on network effects generally, there is a need in   research regarding their operationalization and measurement. Our aim was to specify network effects in  order to answer the question ‘What exactly are network effects?’. We have identified and developed a set   of indicators that determine network effects and assessed them on the information good mobile operating   system. Using the mobile operating systems iOS and Android as a case most of the indicators developed   for measurement of network effects are measurable. The findings of this work contribute to the ongoing  exploration of network effects by demonstrating the interdependence of direct vs. indirect network effects   with the growth of an installed base of an information good." ;
