Einsam durch die Pandemie – soziale Isolierung erhöht Bereitschaft zu egoistischem Verhalten
Die soziale Distanzierung als Maßnahme gegen die COVID-19-Pandemie hat weitreichende gesellschaftliche Folgen, die aus ökonomischer Perspektive bislang kaum diskutiert wurden. Dies geht aus einer Untersuchung des Leibniz-Instituts für Wirtschaftsforschung Halle (IWH) hervor. „Die Erfahrung der sozialen Isolierung führte dazu, dass die Teilnehmenden unserer Studie eher egoistische Entscheidungen treffen“, sagt Studienautorin Sabrina Jeworrek, Juniorprofessorin an der Otto-von-Guericke-Universität Magdeburg und Forschungsgruppenleiterin in der Abteilung Strukturwandel und Produktivität am IWH.

Alone at Home: The Impact of Social Distancing on Norm-consistent Behavior
Sabrina Jeworrek, Joschka Waibel
IWH Discussion Papers,
Nr. 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.

“The Good News about Bad News”: Information about Past Organizational Failure and Its Impact on Worker Productivity

Leadership Quarterly,
Nr. 3,
2021
Abstract
Failure in organizations is very common. Little is known about whether leaders should provide information about past organizational failure to followers and how this might affect their future performance. We conducted a field experiment in which we recruited temporary workers to carry out a phone campaign to attract new volunteers and randomly assigned them to either receive or not to receive information about a failed mail campaign pursuing the same goal. We find that informed workers performed better, regardless of whether they had previously worked on the failed mail campaign or not. Evidence from a second field experiment with students asked to support voluntarily a campaign for reducing food waste corroborates the finding. We explore the role of leadership tactics behind our findings in a third online survey experiment. We conclude that information about past failure is unlikely to have a negative impact on work performance, and might even lead to performance improvement. Implications for future research on the relevance of leadership tactics when giving such information are discussed.

Unethical Employee Behavior Against Coworkers Following Unkind Management Treatment: An Experimental Analysis
Sabrina Jeworrek, Joschka Waibel
Managerial and Decision Economics,
Nr. 5,
2021
Abstract
We study unethical behavior toward unrelated coworkers as a response to managerial unkindness with two experiments. In our lab experiment, we do not find that subjects who experienced unkindness are more likely to cheat in a subsequent competition against another coworker who simultaneously experienced mistreatment. A subsequent survey experiment suggests that behavior in the lab can be explained by individuals' preferences for norm adherence, because unkind management behavior does not alter the perceived moral appropriateness of cheating. However, having no shared experience of managerial unkindness opens up some moral wiggle room for employees to misbehave at the costs of others.

Supranational Rules, National Discretion: Increasing versus Inflating Regulatory Bank Capital?
Reint E. Gropp, Thomas Mosk, Steven Ongena, Ines Simac, Carlo Wix
Abstract
We study how higher capital requirements introduced at the supranational and implemented at the national level affect the regulatory capital of banks across countries. Using the 2011 EBA capital exercise as a quasi-natural experiment, we find that affected banks inflate their levels of regulatory capital without a commensurate increase in their book equity and without a reduction in bank risk. This observed regulatory capital inflation is more pronounced in countries where credit supply is expected to tighten. Our results suggest that national authorities forbear their domestic banks to meet supranational requirements, with a focus on short-term economic considerations.

Can Mentoring Alleviate Family Disadvantage in Adolescence? A Field Experiment to Improve Labor-Market Prospects
Sven Resnjanskij, Jens Ruhose, Simon Wiederhold, Ludger Woessmann
Abstract
We study a mentoring program that aims to improve the labor-market prospects of school-attending adolescents from disadvantaged families by offering them a university-student mentor. Our RCT investigates program effectiveness on three outcome dimensions that are highly predictive of adolescents later labor-market success: math grades, patience-social skills, and labor-market orientation. For low-SES adolescents, the one-to-one mentoring increases a combined index of the outcomes by half a standard deviation after one year, with significant increases in each dimension. Part of the treatment effect is mediated by establishing mentors as attachment figures who provide guidance for the future. The mentoring is not effective for higher-SES adolescents. The results show that substituting lacking family support by other adults can help disadvantaged children at adolescent age.

Ehrenamtliches Engagement von Flüchtlingen zur Förderung sozialer Integration
Sabrina Jeworrek
Wirtschaft im Wandel,
Nr. 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.

Public Bank Guarantees and Allocative Efficiency
Reint E. Gropp, Andre Guettler, Vahid Saadi
Journal of Monetary Economics,
December
2020
Abstract
A natural experiment and matched bank/firm data are used to identify the effects of bank guarantees on allocative efficiency. We find that with guarantees in place unproductive firms receive larger loans, invest more, and maintain higher rates of sales and wage growth. Moreover, firms produce less productively. Firms also survive longer in banks’ portfolios and those that enter guaranteed banks’ portfolios are less profitable and productive. Finally, we observe fewer economy-wide firm exits and bankruptcy filings in the presence of guarantees. Overall, the results are consistent with the idea that guaranteed banks keep unproductive firms in business for too long.

Measuring the Indirect Effects of Adverse Employer Behaviour on Worker Productivity – A Field Experiment
Matthias Heinz, Sabrina Jeworrek, Vanessa Mertins, Heiner Schumacher, Matthias Sutter
Economic Journal,
Nr. 632,
2020
Abstract
We conduct a field experiment to study how worker productivity is affected if employers act adversely towards their co-workers. Our employees work for two shifts in a call centre. In our main treatment, we lay off some workers before the second shift. Compared to two control treatments, we find that the lay-off reduces the productivity of unaffected workers by 12%. We find suggestive evidence that this result is not driven by altered beliefs about the job or the management’s competence, but caused by the workers’ perception of unfair employer behaviour. The latter interpretation is confirmed in a prediction experiment with professional HR managers. Our results suggest that the price for adverse employer behaviour goes well beyond the potential tit for tat of directly affected workers.

The Value of Firm Networks: A Natural Experiment on Board Connections
Ester Faia, Maximilian Mayer, Vincenzo Pezone
CEPR Discussion Papers,
Nr. 14591,
2020
Abstract
This paper presents causal evidence of the effects of boardroom networks on firm value and compensation policies. We exploit exogenous variation in network centrality arising from a ban on interlocking directorates of Italian financial and insurance companies. We leverage this shock to show that firms whose centrality in the network rises after the reform experience positive abnormal returns around the announcement date and are better hedged against shocks. Information dissemination plays a central role: results are driven by firms that have higher idiosyncratic volatility, low analyst coverage, and more uncertainty surrounding their earnings forecasts. Firms benefit more from boardroom centrality when they are more central in the input-output network, hence more susceptible to upstream shocks, when they are less central in the cross-ownership network, or when they have low profitability or low growth opportunities. Network centrality also results in higher directors' compensation, due to rent sharing and improved executives' outside option, and more similar compensation policies between connected firms.
