Grundlegend f{\"u}r diese Ver{\"a}nderungen sind die neuen technologischen M{\"o}glichkeiten, Daten in immer gr{\"o}ßerem Umfang und f{\"u}r vielf{\"a}ltige neue Zwecke zu verarbeiten. Von besonderer Bedeutung ist dabei die Verf{\"u}gbarkeit großer und qualitativ hochwertiger Datens{\"a}tze, insbesondere auf Basis personenbezogener Daten. Sie werden entweder zur Verbesserung der Produktivit{\"a}t, Qualit{\"a}t und Individualit{\"a}t von Produkten und Dienstleistungen oder gar zur Entwicklung neuartiger Dienstleistungen verwendet. Heute wird das Nutzerverhalten, trotz weltweit steigender gesetzlicher Anforderungen an den Schutz personenbezogener Daten, aktiver und umfassender verfolgt als je zuvor. Dies wirft vermehrt ethische, moralische und gesellschaftliche Fragen auf, die nicht zuletzt durch popul{\"a}re F{\"a}lle des Datenmissbrauchs in den Vordergrund der politischen Debatte ger{\"u}ckt sind. Angesichts dieses Diskurses und der gesetzlichen Anforderungen muss heutiges Datenmanagement drei Bedingungen erf{\"u}llen: Erstens die Legalit{\"a}t bzw. Gesetzeskonformit{\"a}t der Nutzung, zweitens die ethische Legitimit{\"a}t. Drittens sollte die Datennutzung aus betriebswirtschaftlicher Sicht wertsch{\"o}pfend sein. Im Rahmen dieser Bedingungen verfolgt die vorliegende kumulative Dissertation vier Forschungsziele mit dem Fokus, ein besseres Verst{\"a}ndnis (1) der Herausforderungen bei der Umsetzung von Gesetzen zum Schutz von Privatsph{\"a}re, (2) der Faktoren, die die Bereitschaft der Kunden zur Weitergabe pers{\"o}nlicher Daten beeinflussen, (3) der Rolle des Datenschutzes f{\"u}r das digitale Unternehmertum und (4) der interdisziplin{\"a}ren wissenschaftlichen Bedeutung, deren Entwicklung und Zusammenh{\"a}nge zu erlangen.}, language = {en} } @incollection{BalderjahnHedergottAppenfelleretal.2021, author = {Balderjahn, Ingo and Hedergott, Doreen and Appenfeller, Dennis and Peyer, Mathias}, title = {Choice-Based Conjointanalyse}, series = {Conjointanalyse}, booktitle = {Conjointanalyse}, editor = {Baier, Daniel and Brusch, Michael}, edition = {2., {\"u}berarbeitete und erweiterte}, publisher = {Springer Gabler}, address = {Berlin ; Heidelberg}, isbn = {978-3-662-63363-2}, doi = {10.1007/978-3-662-63364-9_8}, pages = {185 -- 203}, year = {2021}, abstract = {Die auswahlbasierte oder auch Choice-Based Conjointanalyse (CBC) ist die derzeit wohl beliebteste Variante der Conjointanalyse.

The study assumes that people will only lower their level of consumption if doing so does not also lower personal wellbeing. More precisely, this research investigates how specific subtypes of sustainable anticonsumption (e.g., voluntary simplicity, collaborative consumption, and debt-free living) relate to different states of consumer's wellbeing (e.g., financial, psychosocial, and subjective wellbeing). This work also examines whether consumer empowerment can improve personal wellbeing and strengthen the anticonsumption wellbeing relationship. The results show that voluntarily foregoing consumption does not reduce wellbeing and consumer empowerment plays a significant role in supporting sustainable pathways to consumer wellbeing. This study reasons that empowerment improves consumer sovereignty, but may be detrimental for consumers heavily concerned about debt-free living. The present investigation concludes by proposing implications for public and consumer policymakers wishing to promote appropriate sustainable (anticonsumption) pathways to consumer wellbeing.}, language = {en} } @article{AbuJarourAjjanFedorowiczetal.2021, author = {AbuJarour, Safa'a and Ajjan, Haya and Fedorowicz, Jane and K{\"o}ster, Antonia}, title = {ICT support for refugees and undocumented immigrants}, series = {Communications of the Association for Information Systems : CAIS}, volume = {48}, journal = {Communications of the Association for Information Systems : CAIS}, publisher = {Association for Information Systems}, address = {New York, NY}, issn = {1529-3181}, doi = {10.17705/1CAIS.04840}, pages = {456 -- 475}, year = {2021}, abstract = {Immigrant integration has become a primary political concern for leaders in Germany and the United States. The information systems (IS) community has begun to research how information and communications technologies can assist immigrants and refugees, such as by examining how countries can facilitate social-inclusion processes. Migrants face the challenge of joining closed communities that cannot integrate or fear doing so. We conducted a panel discussion at the 2019 Americas Conference on Information Systems (AMCIS) in Cancun, Mexico, to introduce multiple viewpoints on immigration. In particular, the panel discussed how technology can both support and prevent immigrants from succeeding in their quest. We conducted the panel to stimulate a thoughtful and dynamic discussion on best practices and recommendations to enhance the discipline's impact on alleviating the challenges that occur for immigrants in their host countries. In this panel report, we introduce the topic of using ICT to help immigrants integrate and identify differences between North/Central America and Europe. We also discuss how immigrants (particularly refugees) use ICT to connect with others, feel that they belong, and maintain their identity. We also uncover the dark and bright sides of how governments use ICT to deter illegal immigration. Finally, we present recommendations for researchers and practitioners on how to best use ICT to assist with immigration.}, language = {en} } @article{AbuJarourAjjanFedorowiczetal.2021, author = {AbuJarour, Safa'a and Ajjan, Haya and Fedorowicz, Jane and Owens, Dawn}, title = {How working from home during COVID-19 affects academic productivity}, series = {Communications of the Association for Information Systems : CAIS}, volume = {48}, journal = {Communications of the Association for Information Systems : CAIS}, publisher = {Association for Information Systems}, address = {New York, NY}, issn = {1529-3181}, doi = {10.17705/1CAIS.04808}, pages = {55 -- 64}, year = {2021}, abstract = {The coronavirus disease of 2019 (COVID-19) pandemic has forced most academics to work from home.

To shed light on the consequences of videoconferencing at work, this study takes a granular look at the implications of the self-view feature for meeting outcomes. Building on self-awareness research and self-regulation theory, we argue that by heightening the state of self-awareness, self-view engagement depletes participants' mental resources and thereby can undermine online meeting outcomes. Evaluation of our theoretical model on a sample of 179 employees reveals a nuanced picture. Self-view engagement while speaking and while listening is positively associated with self-awareness, which, in turn, is negatively associated with satisfaction with meeting process, perceived productivity, and meeting enjoyment. The criticality of the communication role is put forward: looking at self while listening to other attendees has a negative direct and indirect effect on meeting outcomes; however, looking at self while speaking produces equivocal effects.}, language = {en} } @article{KalkuhlSteckelEdenhofer2020, author = {Kalkuhl, Matthias and Steckel, Jan Christoph and Edenhofer, Ottmar}, title = {All or nothing}, series = {Journal of environmental economics and management}, volume = {100}, journal = {Journal of environmental economics and management}, publisher = {Elsevier}, address = {San Diego}, issn = {0095-0696}, doi = {10.1016/j.jeem.2019.01.012}, pages = {21}, year = {2020}, abstract = {This paper develops a new perspective on stranded assets in climate policy using a partial equilibrium model of the energy sector. Political-economy related aspects are considered in the government's objective function. Lobbying power of firms or fiscal considerations by the government lead to time inconsistency: The government will deviate from a previously announced carbon tax which creates stranded assets. Under rational expectations, we show that a time-consistent policy outcome exists with either a zero carbon tax or a prohibitive carbon tax that leads to zero fossil investments - an "all-or-nothing" policy. Although stranded assets are crucial to such a bipolar outcome, they disappear again under time-consistent policy. Which of the two outcomes (all or nothing) prevails depends on the lobbying power of owners of fixed factors (land and fossil resources) but not on fiscal revenue considerations or on the lobbying power of renewable or fossil energy firms.}, language = {en} } @article{MargaryanSaniterSchumannetal.2022, author = {Margaryan, Shushanik and Saniter, Nils and Schumann, Mathias and Siedler, Thomas}, title = {Do internships pay off?}, series = {Journal of human resources}, volume = {57}, journal = {Journal of human resources}, number = {4}, publisher = {University of Wisconsin Press}, address = {Madison}, issn = {0022-166X}, doi = {10.3368/jhr.57.4.0418-9460R2}, pages = {1242 -- 1275}, year = {2022}, abstract = {We study the causal effect of student internship experience in firms on earnings later in life.

To nudge primary school children into a long-term habit of exercising, the German state of Saxony distributed sports club membership vouchers among all 33,000 third graders in 2009. In 2018, we carried out a register-based survey to evaluate the policy. Even after a decade, awareness of the voucher program was significantly higher in the treatment group. We also find that youth received and redeemed the vouchers. However, we do not find significant short- or long-term effects on sports club membership, physical activity, overweightness, or motor skills. Apparently, membership vouchers for children are not a strong enough policy tool to overcome barriers to exercise regularly.}, language = {en} }
