Design/methodology/approach A field experiment was set up over a period of three months to test the effects of two variants of an advertisement campaign (a social vs a discrete ad) on the modeled networked and discrete ROIs. Findings The authors find that emphasizing discrete user actions leads to lower network gains, but higher monetary returns while the social action emphasis produces higher network gains, but lower monetary returns. The study further suggests that social action focus is preferable for brand promotion and engagement, whereas the discrete action focus is suitable for boosting sales and website traffic. Practical implications Several potential implications for social media researchers and marketers are also discussed. Originality/value The authors for the first time showed that that the social media returns are derived not only from individual actions taken by the user (e.g. likes and shares) but also from users’ social interdependencies and the additional exposure that results from network effects. }}, author = {{Khan, Gohar and Mohaisen, Manar and Trier, Matthias}}, issn = {{1066-2243}}, journal = {{Internet Research}}, keywords = {{Economics and Econometrics, Sociology and Political Science, Communication}}, number = {{2}}, pages = {{631--652}}, publisher = {{Emerald}}, title = {{{The network ROI}}}, doi = {{10.1108/intr-07-2018-0346}}, volume = {{30}}, year = {{2019}}, } @inbook{36878, abstract = {{Dieser Sammelband ist ein Ergebnis aus unserem Forschungszusammenhang „Die Kinderladenbewegung: Biographische Auswirkungen und gesellschaftspolitische Einflüsse institutioneller Erziehungsarrangements“, der uns seit 2011 als Nachwuchsforscherinnengruppe der Hans-Böckler-Stiftung verbindet.
