Paid Vacation Use: The Role of Works Councils

Laszlo Goerke Sabrina Jeworrek

in: Economic and Industrial Democracy, im Erscheinen


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.

Wage Delegation in the Field

Sabrina Jeworrek Vanessa Mertins

in: Journal of Economics & Management Strategy, Nr. 4, 2019


By conducting a natural field experiment, we analyze the managerial policy of delegating the wage choice to employees. We find that this policy enhances performance significantly, which is remarkable since allocated wage premiums of the same size have no effect at all. Observed self‐imposed wage restraints and absence of negative peer effects speak in favor of wage delegation, although the chosen wage premium levels severely dampen its net value. Additional experimental and survey data provide important insights into employees' underlying motivations.

Gender Stereotypes still in MIND: Information on Relative Performance and Competition Entry

Sabrina Jeworrek

in: Journal of Behavioral and Experimental Economics, October 2019


By conducting a laboratory experiment, I test whether the gender tournament gap diminishes in its size after providing information on the relative performance of the two genders. Indeed, the gap shrinks sizeably, it even becomes statistically insignificant. Hence, individuals’ entry decisions seem to be driven not only by incorrect self-assessments in general but also by incorrect stereotypical beliefs about the genders’ average abilities. Overconfident men opt less often for the tournament and, thereby, increase their expected payoff. Overall efficiency, however, is not affected by the intervention.

Indirekte Effekte von als unfair wahrgenommenem Arbeitgeberverhalten auf die Produktivität von Beschäftigten

Sabrina Jeworrek

in: Wirtschaft im Wandel, Nr. 3, 2018


Jede Organisation, die darüber nachdenkt zu restrukturieren, Löhne zu kürzen oder Angestellte zu entlassen, sollte auch über mögliche Reaktionen der persönlich nicht betroffenen Arbeitnehmer nachdenken. Dieser Beitrag präsentiert Ergebnisse eines Feldexperiments. Es offenbart, dass die als unfair wahrgenommene Handlung des Arbeitgebers – in diesem Fall die Entlassung von Arbeitskollegen – die anschließende Produktivität der nicht direkt betroffenen Arbeitskräfte mindert. Als Teil des Experiments antizipierten erfahrene Personalmanager zwar im Durchschnitt erfolgreich die Konsequenzen unfairen Arbeitgeberverhaltens auf nicht betroffene Arbeitnehmer, einzeln lagen sie jedoch oft daneben.

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

Sabrina Jeworrek Vanessa Mertins Bernd Josef Leisen

in: IWH-Diskussionspapiere, Nr. 17, 2019


Refugee integration requires broad support from the host society, but only a minority of the host population is actively engaged. Given that most individuals reciprocate kind behaviour, 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. Importantly, this result holds for individuals who have not been in contact with refu-gees. We complement this investigation with experiments in the lab and the field that confirm our findings for actual behaviour.

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

Sabrina Jeworrek Vanessa Mertins

in: IWH-Diskussionspapiere, Nr. 10, 2019


The mission of a job does not only affect the type of worker attracted to an organisation, but may also provide incentives to an existing workforce. We conducted a natural field experiment with 267 short-time workers and randomly allocated them to either a prosocial or a commercial job. Our data suggest that the mission of a job itself has a performance enhancing motivational impact on particular individuals only, i.e., workers 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 15 percent. This effect seems to be a universal phenomenon which is not driven by information about the alternative job, the choice itself or a particular subgroup.

Crowdsourced Innovation: How Community Managers Affect Crowd Activities

Sabrina Jeworrek Lars Hornuf

in: IWH-Diskussionspapiere, Nr. 13, 2018


In this study, we investigate whether and to what extent community managers in online collaborative communities can stimulate crowd activities through their engagement. Using a novel data set of 22 large online idea crowdsourcing campaigns, we find that active engagement of community managers positively affects crowd activities in an inverted U-shaped manner. Moreover, we evidence that intellectual stimulation by managers increases community participation, while individual consideration of users has no impact on user activities. Finally, the data reveal that community manager activities that require more effort, such as media file uploads instead of simple written comments, have a larger effect on crowd participation.
