Network effects in technology acceptance: Laboratory experimental evidence

This research analyzes network effects in technology acceptance. The hypothesis is that the size of the user network affects technology acceptance. Even today, empirical measurement of network effects is challenging and there is a lack of experimental evidence. In order to investigate andmeasure the relationechnology acceptance etwork effects etwork externalities aboratory experiment ship between network size (number of adopters) and user acceptance, technology acceptance research needs to broaden its scope and approaches. To overcome this limitationwe reproduce a particular type of technology acceptance process in a laboratory experiment, controlling for user network size and testing its influence onuser perceptions and, ultimately, on acceptance decisions.Wemeasured user perceptions and analyzed the data using consolidated and tested technology acceptance models. The results confirm our hypothesis, showing a significant effect of user network size on user perceptions. Finally, we discuss geria the theoretical and mana
