The Effect of Community Managers on Online Idea Crowdsourcing Activities

Lars Hornuf Sabrina Jeworrek

in: Journal of the Association for Information Systems, No. 1, 2023

Abstract

In this study, we investigate whether and to what extent community managers in online collaborative communities can stimulate community activities through their engagement. Using a novel data set of 22 large online idea crowdsourcing campaigns, we find that moderate but steady manager activities are adequate to enhance community participation. Moreover, we show that appreciation, motivation, and intellectual stimulation by community managers are positively associated with community participation but that the effectiveness of these communication strategies depends on the form of participation managers wish to encourage. Finally, the data reveal that community manager activities requiring more effort, such as media file uploads vs. simple written comments, have a stronger effect on community participation.

Mission, Motivation, and the Active Decision to Work for a Social Cause

Sabrina Jeworrek Vanessa Mertins

in: Nonprofit and Voluntary Sector Quarterly, No. 2, 2022

Abstract

The mission of a job affects the type of worker attracted to an organization but may also provide incentives to an existing workforce. We conducted a natural field experiment with 246 short-term workers. We randomly allocated some of these workers to either a prosocial or a commercial job. Our data suggest that the mission of a job has a performance-enhancing motivational impact on particular individuals only, those with a prosocial attitude. However, the mission is very important if it has been actively selected. Those workers who have chosen to contribute to a social cause outperform the ones randomly assigned to the same job by about half a standard deviation. This effect seems to be a universal phenomenon that is not driven by information about the alternative job, the choice itself, or a particular subgroup.

Gift-Exchange in Society and the Social Integration of Refugees: Evidence from a Field, a Laboratory, and a Survey Experiment

Sabrina Jeworrek Bernd Josef Leisen Vanessa Mertins

in: Journal of Economic Behavior and Organization, December 2021

Abstract

Refugee integration requires broad support from the host society, but only a minority is actively engaged. Given that most individuals reciprocate kind behavior, we examine the idea that the proportion of supporters will increase as a reciprocal response to refugees’ contributions to society through volunteering. Our nationwide survey experiment shows that citizens’ intentions to contribute time and money rise significantly when they learn about refugees’ pro-social activities. However, we find a substantial heterogeneity in the observed treatment effects. Individuals with a high reciprocal inclination show higher willingness to contribute time, while individuals with a lower reciprocal inclination are ready to contribute money after learning about the refugees' good deeds. Information regarding the possibility to establish a mutual support relationship with the refugees does not generally increase the willingness to contribute time or money beyond the information on refugees’ general contributions to the society. We complement this investigation with experiments in the lab and the field that confirm our findings for actual behavior.

Erinnerung an soziale Isolation des Lockdowns macht Menschen egoistischer

Sabrina Jeworrek Joschka Waibel

in: Wirtschaft im Wandel, No. 3, 2021

Abstract

Nachdem Teilnehmer eines Online-Experiments an die soziale Isolierung des Lockdowns erinnert wurden, verhielten sich diese egoistischer als eine neutrale Vergleichsgruppe. Allerdings beurteilten Teilnehmer eines weiteren Experiments, die ebenfalls an die soziale Isolation im Lockdown erinnert wurden, ein solches egoistisches Verhalten als prinzipiell sozial unangemessen. Daraus lässt sich schließen, dass lediglich die Neigung zur Befolgung sozialer Normen, welche menschliches Verhalten in den verschiedensten Lebenssituationen maßgeblich beeinflussen, durch die soziale Distanzierung gesunken ist. Auch für eine Zeit nach der Bewältigung der Corona-Pandemie werfen diese Ergebnisse Fragen auf: Wie lässt sich in einer digitalisierten Welt, in der persönliche Interaktionen immer seltener werden, die Bereitschaft zur Einhaltung sozialer Normen aufrechterhalten?

Paid Vacation Use: The Role of Works Councils

Laszlo Goerke Sabrina Jeworrek

in: Economic and Industrial Democracy, No. 3, 2021

Abstract

The article investigates the relationship between codetermination at the plant level and paid vacation in Germany. From a legal perspective, works councils have no impact on vacation entitlements, but they can affect their use. Employing data from the German Socio-Economic Panel (SOEP), the study finds that male employees who work in an establishment, in which a works council exists, take almost two additional days of paid vacation annually, relative to employees in an establishment without such institution. The effect for females is much smaller, if discernible at all. The data suggest that this gender gap might be due to the fact that women exploit vacation entitlements more comprehensively than men already in the absence of a works council.

Where to Go? High-skilled Individuals’ Regional Preferences

Sabrina Jeworrek Matthias Brachert

in: IWH Discussion Papers, No. 27, 2022

Abstract

We conduct a discrete choice experiment to investigate how the location of a firm in a rural or urban region affects job attractiveness and contributes to the spatial sorting of university students and graduates. We characterize the attractiveness of a location based on several dimensions (social life, public infrastructure, connectivity) and combine this information with an urban or rural attribution. We also vary job design as well as contractual characteristics of the job. We find that job offers from companies in rural areas are generally considered less attractive. This is true regardless of the attractiveness of the region. The negative perception is particularly pronounced among persons with urban origin and singles. These persons rate job offers from rural regions significantly worse. In contrast, high-skilled individuals who originate from rural areas as well as individuals with partners and kids have no specific preference for jobs in urban or rural areas.

Alone at Home: The Impact of Social Distancing on Norm-consistent Behavior

Sabrina Jeworrek Joschka Waibel

in: IWH Discussion Papers, No. 8, 2021

Abstract

Around the globe, the COVID-19 pandemic has turned daily live upside down since social distancing is probably the most effective means of containing the virus until herd immunity is reached. Social norms have been shown to be an important determinant of social distancing behaviors. By conducting two experiments and using the priming method to manipulate social isolation recollections, we study whether social distancing has in turn affected norms of prosociality and norm compliance. The normative expectations of what behaviors others would approve or disapprove in our experimental setting did not change. Looking at actual behavior, however, we find that persistent social distancing indeed caused a decline in prosociality – even after the relaxation of social distancing rules and in times of optimism. At the same time, our results contain some good news since subjects seem still to care for norms and become more prosocial once again after we draw their attention to the empirical norm of how others have previously behaved in a similar situation.
