摘要:AbstractThe purpose of this study is to search if consumers are aware of network effects. If consumers are rational, they will make their consumption decisions by thinking about maximization of their utility without paying too much. The quality of a good does not only depend on producer's decisions in network markets. Also the number of other customers, affect the quality of a good. First we reviewed literature about network externalities and effects. Secondly, we analyzed the survey which is conducted to measure network externalities perceptions. The survey is conducted on Beykent University Vocational School pupils. As a result we reached interesting results about the network perceptions of pupils.
