Stadtfrust und Landlust? Über regionale Präferenzen von hochqualifizierten Individuen
Matthias Brachert, Sabrina Jeworrek
Wirtschaft im Wandel,
Nr. 2,
2023
Abstract
Die Verfügbarkeit von qualifizierten Arbeitskräften ist eine zentrale Voraussetzung für den Erfolg eines Unternehmens. Eine städtische Lohnprämie zieht Beschäftigte an und verstärkt den Urbanisierungstrend. In unserer Studie untersuchen wir, ob nicht nur die Lohnprämie, sondern auch der Unternehmensstandort selbst die Attraktivität eines Arbeitsplatzes beeinflusst. Mittels eines experimentellen Untersuchungsdesigns zeigen wir, dass hochqualifizierte Arbeitnehmer unabhängig vom gezahlten Lohn eine Präferenz für städtische Standorte haben, selbst wenn ländliche Standorte attraktive regionale Eigenschaften aufweisen. Der beobachtete Effekt ist allerdings getrieben von Personen, die in städtischen Gebieten aufgewachsen sind. Personen, die in ländlichen Gebieten aufgewachsen sind, zeigen dagegen keine regionalen Präferenzen, weder für noch gegen städtische Gebiete.

Discrimination in Universal Social Programs? A Nationwide Field Experiment on Access to Child Care
Henning Hermes, Philipp Lergetporer, Fabian Mierisch, Frauke Peter, Simon Wiederhold
IWH Discussion Papers,
Nr. 12,
2023
Abstract
Although explicit discrimination in access to social programs is typically prohibited, more subtle forms of discrimination prior to the formal application process may still exist. Unveiling this phenomenon, we provide the first causal evidence of discrimination against migrants seeking child care. We send emails from fictitious parents to > 18, 000 early child care centers across Germany, inquiring about slot availability and application procedures. Randomly varying names to signal migration background, we find that migrants receive 4.4 percentage points fewer responses. Replies to migrants contain fewer slot offers, provide less helpful content, and are less encouraging. Exploring mechanisms using three additional treatments, we show that discrimination is stronger against migrant boys. This finding suggests that anticipated higher effort required for migrants partly drives discrimination, which is also supported by additional survey and administrative data. Our results highlight that difficult-to-detect discrimination in the pre-application phase could hinder migrants’ access to universal social programs.

The Impact of Lowering Carbon Emissions on Corporate Labour Investment: A Quasi-Natural Experiment

Abstract
We examine the impact of low-carbon city (LCC) initiatives on labour investment decisions (quantity, quality, and well-being). Using a time-varying difference-in-differences approach based on staggered implementations of such a pilot program, we report an inefficient outcome - absolute deviation of labour investment from the optimal net hiring – especially for firms in labour-intensive industries and firms with high financial slack or adjustment costs. We, however, observe increased investments in highly skilled personnel and compensated with employee stock ownership, especially by firms under intense pressure to reduce carbon emissions. Such initiatives are also closely associated with the significant enhancement of workplace safety. Overall, LCC helps to upgrade the corporate labour structure by hiring more skilled employees through reduced agency problems and heightened green innovation.

Males Should Mail? Gender Discrimination in Access to Childcare
Henning Hermes, Philipp Lergetporer, Fabian Mierisch, Frauke Peter, Simon Wiederhold
American Economic Association Papers and Proceedings,
May
2023
Abstract
This study investigates discrimination against women when searching and applying for childcare in a nationwide field experiment. We send emails from fictitious parents to 9,313 childcare centers in Germany inquiring about access to childcare. We randomize whether the email is sent by the child's mother or father. Our results show that women receive shorter and less positive responses than men. The probability of receiving a response does not differ by gender, highlighting the importance of going beyond response rates to detect discrimination. We provide suggestive evidence that regional differences in gender discrimination are related to gender norms.

How Early Childcare Can Boost the Labour Market Success of Lower-Educated Mothers
Henning Hermes, Marina Krauss, Philipp Lergetporer, Frauke Peter, Simon Wiederhold
VoxEU,
April
2023
Abstract
In most countries, childbirth has a negative impact on the labour market outcomes of mothers, especially for those with lower socioeconomic status. This column presents findings from a field experiment in Germany demonstrating that access to universal early childcare increases full-time employment and household income of mothers with lower socioeconomic status. To improve the labour market outcomes of these mothers, policymakers must provide easier access to early childcare and expand early childcare slots.

Oxytocin, Empathy, Altruism and Charitable Giving: Experimental Evidence from Blood Donations
Irena Jukić, Dejan Kovač, Danijela Vuletić Čugalj
IWH Discussion Papers,
Nr. 4,
2023
Abstract
We conducted a field experiment in the natural setting of blood donations to test how oxytocin relates to empathy and altruism. We randomly assigned blood donors in the Croatian Institute for Transfusion Medicine to three groups with the aim to induce different levels of empathy by showing a neutral video to the donors from the control group and an emotional to the donors from the first and second treatment groups. In addition to watching the emotional video, donors from the second treatment group are given a gift which relates to the emotional story from the video. We find no effect of our treatment on induced levels of oxytocin. Null effects of our treatments could be explained by the above average baseline levels of oxytocin and inability of our treatments to provoke emotional stimuli in blood donors. Nonetheless, for our empathy measures we find the effect of gift exchange on empathic concerns, but not on perspective taking. After our experimental treatments, we followed the return of our blood donors for a whole year. We find that only variable which consistently predicts return for blood donation in stated period is the number of previous donations. From policy perspective it is an important finding. Especially for hospitals and other blood providers when faced with time and resource constraints.

Where to Go? High-skilled Individuals’ Regional Preferences
Sabrina Jeworrek, Matthias Brachert
IWH Discussion Papers,
Nr. 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.
