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
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.

Ehrenamtliches Engagement von Flüchtlingen zur Förderung sozialer Integration
Sabrina Jeworrek
Wirtschaft im Wandel,
No. 3,
2020
Abstract
Die soziale Integration von Flüchtlingen kann einen substanziellen Beitrag zu deren ökonomischer Integration leisten, häufig sind negative Einstellungen der Bevölkerung gegenüber ethnischen Minderheiten aber ein Schlüsselfaktor für Integrationsprobleme. Die Förderung ehrenamtlichen Engagements von Flüchtlingen könnte eine Lösung darstellen und
den Integrationsprozess positiv beeinflussen. Basierend auf den Daten dreier unterschiedlicher Experimente zeigt dieser Beitrag, dass Einheimische in höherem Maße bereit sind, die Integration von Flüchtlingen persönlich oder finanziell zu unterstützen, wenn sich Flüchtlinge an ihrem neuen Wohnort gesellschaftlich engagieren. Natürlich findet sich eine gewisse Heterogenität hinsichtlich der Neigung, eher persönlich oder eher finanziell zu unterstützen. Für die unterschiedlichsten Personengruppen gilt aber, dass ehrenamtliches Flüchtlingsengagement zumindest auf eine dieser beiden Optionen einen positiven Effekt ausübt.

Wage Delegation in the Field
Sabrina Jeworrek, Vanessa Mertins
Journal of Economics and Management Strategy,
No. 4,
2019
Abstract
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.

Abstract
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 refugees. We complement this investigation with experiments in the lab and the field that confirm our findings for actual behaviour.

When the Meaning of Work Has Disappeared: Experimental Evidence on Employees’ Performance and Emotions
Adrian Chadi, Sabrina Jeworrek, Vanessa Mertins
Management Science,
No. 6,
2017
Abstract
This experiment tests for a causal relationship between the meaning of work and employees’ motivation to perform well. The study builds on an existing employer–employee relationship, adding realism to the ongoing research of task meaning. Owing to an unexpected project cancelation, we are able to study how varying the information provided about the meaning of previously conducted work — without the use of deception, but still maintaining a high level of control — affects subsequent performance. We observe a strong decline in exerted effort when we inform workers about the meaninglessness of a job already done. Our data also suggests that providing a supplemental alternative meaning perfectly compensates for this negative performance effect. Individual characteristics such as reciprocal inclinations and trust prompt different reactions. The data also show that the meaning of work affects workers’ emotions, but we cannot establish a clear relationship between emotional responses and performance.

Entry and Strategic Information Display in Credit Markets
Jan Bouckaert, Hans Degryse
Economic Journal,
No. 513,
2006
Abstract
In many countries, lenders voluntarily provide information about their borrowers to private credit registries. A recent World Bank survey reveals that the display of a lender's own borrower information is often not reciprocated. That is, access to these registries does not require the prior provision of proprietary data. We argue that incumbent lenders release information about a portion of their profitable borrowers for strategic reasons. The reasoning is that the pool of unreleased borrowers becomes characterised by a severe adverse selection problem. This prevents the entrants from bidding for all the incumbent's profitable borrowers and reduces their scale of entry.
