Abstract
We study how individuals' perceptions of current and future levels of income inequality change during periods of expansionary fiscal policy. In a randomized controlled trial (RCT), we provide information on fiscal expansion to a representative sample of the German population. Our findings reveal that combining a fact-based (numerical) information treatment with a narrative treatment about fiscal expansion plans reduces inequality expectations among respondents who are ex-ante dissatisfied with the government's economic policy. These effects are more pronounced among respondents without a college degree or with low political interest, highlighting the importance of narrative information for individuals who are likely to benefit most from it. We explore potential mechanisms by examining revisions in macro- and micro-level assessments of future economic conditions and find that respondents primarily update their expectations regarding economic growth and individual layoff risk.

Facts or Feelings? The Role of Relatable Narratives in Shaping Inflation Expectations

IWH Discussion Papers,
No. 10,
2026
Abstract
We examine whether combining factual information on inflation levels and forecasts with a narrative can persistently shape consumers’ inflation expectations. In a preregistered randomized controlled trial with a representative sample of 3,000 German consumers, participants received either numerical or textual information about inflation rates, with or without an accompanying narrative. All treatments immediately lower inflation expectations, with numerical information eliciting stronger adjustments. Adding a narrative produces no additional immediate effect, confirming that it conveys no new information. However, only the combination of numerical information with a narrative yields a lasting reduction in inflation expectations and forecast uncertainty still observable after four weeks. Our results suggest that combining precise information with a narrative enhances information retention and can lead to more persistent shifts in consumers’ beliefs. The effects are strongest when respondents perceive the narrative as relatable and emotionally engaging, and among those with low financial literacy and limited knowledge of inflation.

The Causal Impact of Gender Norms on Mothers’ Employment Attitudes and Expectations

No. 28,

Abstract
This field experiment investigates the causal impact of mothers’ perceptions of gender norms on their employment attitudes and labor-supply expectations. We provide mothers of young children in Germany with information about the prevailing gender norm regarding maternal employment in their city. At baseline, over 70% of mothers incorrectly perceive this gender norm as too conservative – the most pronounced misperception among the various gender norms we examine. Our randomized information treatment improves the accuracy of these perceptions, significantly reducing the share of mothers who perceive gender norms as overly conservative. The treatment also shifts mothers’ own labormarket attitudes in a more liberal direction. Leveraging the fact that we assessed attitudes in a prior survey, we show that specifically the shifted attitude is a strong predictor of mothers’ future labor-market participation. Consistently, treated mothers are more likely to plan an increase in their working hours, particularly those with existing support to facilitate their employment.

Early Child Care, Maternal Labor Supply, and Gender Equality: A Randomized Controlled Trial?
Henning Hermes, Marina Krauß, Philipp Lergetporer, Frauke Peter, Simon Wiederhold
IWH Discussion Papers,
No. 14,
2024
Abstract
We provide experimental evidence that enabling access to universal early child care increases maternal labor supply and promotes gender equality among families with lower socioeconomic status (SES). Our intervention offers information and customized help with child care applications, leading to a boost in child care enrollment among lower-SES families. 18 months after the intervention, we find substantial increases in maternal full-time employment (+160%), maternal earnings (+22%), and household income (+10%). Intriguingly, the positive employment effects are not only driven by extended hours at child care centers, but also by an increase in care hours by fathers. Gender equality also benefits more broadly from better access to child care: The treatment improves a gender equality index that combines information on intra-household division of working hours, care hours, and earnings by 40% of a standard deviation, with significant increases in each dimension. For higher-SES families, we consistently observe negligible, insignificant treatment effects.

Frühkindliche Betreuung erhöht den Arbeitsmarkterfolg von Müttern ohne Abitur

No. 3,
2023
Abstract
In den meisten Ländern wirkt sich die Geburt eines Kindes negativ auf den Arbeitsmarkterfolg von Müttern aus, insbesondere bei Müttern mit niedrigerem Schulabschluss. In diesem Beitrag werden die Ergebnisse eines Feldexperiments in Deutschland vorgestellt, in dem Familien bei der Bewerbung für einen Platz in einer Kindertagesstätte (Kita) unterstützt wurden. Die Ergebnisse zeigen, dass der verbesserte Zugang zu frühkindlicher Betreuung die Wahrscheinlichkeit erhöht, dass Mütter ohne Abitur in Vollzeit arbeiten, und deren Haushaltseinkommen steigert. Um den Arbeitsmarkterfolg von Müttern zu verbessern, sollte die Politik den Zugang zu frühkindlicher Betreuung erleichtern und die Zahl der Kita-Plätze noch weiter erhöhen.

IEB Report "Education Policy: Quality and Equality of Opportunity",
2023
Abstract
In this report, we discuss the results of our randomized controlled trial (RCT) of a nationwide mentoring program designed to improve the labor-market prospects of disadvantaged adolescents in Germany (Resnjanskij et al., 2023). The study is motivated by the high persistence of inequality across generations present even in countries with comprehensive social welfare systems (Alvaredo et al., 2018). In particular, the school-to-work transition is a decisive moment that determines the differences in later labor-market outcomes of young adolescents.

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.

Attracting Early-Stage Investors: Evidence From a Randomized Field Experiment

Journal of Finance,
Vol. 72 (2),
2017
Abstract
This paper uses a randomized field experiment to identify which start-up characteristics are most important to investors in early-stage firms. The experiment randomizes investors? information sets of fund-raising start-ups. The average investor responds strongly to information about the founding team, but not to firm traction or existing lead investors. We provide evidence that the team is not merely a signal of quality, and that investing based on team information is a rational strategy. Together, our results indicate that information about human assets is causally important for the funding of early-stage firms and hence for entrepreneurial success.

Children, Career, and Compromises: To what Extent does Offspring Affect Labour Force Participation and Career Opportunities of Women in Germany?

Wirtschaft im Wandel,
No. 11,

Abstract
Aus demographischer Sicht steuert der deutsche Arbeitsmarkt in den kommenden zwei Jahrzehnten auf eine beachtliche Herausforderung zu: Große Geburtskohorten erreichen demnächst das Rentenalter, und die Bevölkerung im erwerbsfähigen Alter schrumpft. In der politischen Diskussion wird – als ein möglicher Ansatzpunkt – auf die Erwerbstätigkeit der Frauen abgestellt, um die damit verbundenen Probleme zu beheben. Einerseits soll deren Erwerbstätigkeit gesteigert, andererseits jedoch das eigentliche Problem – der Geburtenrückgang – dadurch nicht noch weiter verschärft werden.
Der vorliegende Beitrag beschreibt auf Basis des Sozio-oekonomischen Panels (SOEP) mögliche Abschläge in der beruflichen Karriere von Müttern gegenüber kinderlosen Frauen. Hierzu wird einerseits der Erwerbsumfang und andererseits der realisierte Lohn bzw. das berufliche Prestige der ausgeübten Tätigkeit analysiert, wobei zwischen Ost- und Westdeutschland unterschieden wird.
Infolge der Geburt eines Kindes sinkt die Arbeitsmarktpartizipation der Mutter deutlich, wobei sie in Ostdeutschland innerhalb kurzer Zeit wieder das vorherige Niveau erreicht. Im Unterschied dazu steigt die Erwerbsneigung in Westdeutschland langsamer an und verbleibt auf einem langfristig niedrigeren Niveau. Hinzu kommt hier eine höhere Neigung zur Beschäftigung in Teilzeit, während der realisierte Erwerbsumfang in Ostdeutschland aufgrund des höheren Arbeitslosigkeitsrisikos hinter der Partizipationsneigung zurückbleibt. Im Vergleich zu Frauen ohne Kinder erzielen Mütter in Westdeutschland geringere Löhne. Unter Berücksichtigung unbeobachteter Heterogenität zeigen sich moderate Lohnabschläge auch für ostdeutsche Mütter. Im Hinblick auf berufliches Prestige lässt sich lediglich für Frauen in Westdeutschland ein negativer Zusammenhang mit der Kinderzahl finden.
Die Befunde lassen in der Gesamtschau unterschiedlich starke Effekte von Kindern auf den Karrierepfad zwischen den betrachteten Regionen sichtbar werden. Hierbei könnte die reichlichere Ausstattung mit Kindertagesstättenplätzen in Ostdeutschland eine Rolle spielen.
