Dekarbonisierung in Europa: Regionalwirtschaftliche Effekte in ausgewählten Kohleregionen und kohlenstoffintensiven Regionen Europa
Katja Heinisch, Oliver Holtemöller, Christoph Schult
Wirtschaft im Wandel,
Nr. 3,
2023
Abstract
Die EU hat mit dem „Fit for 55“-Paket zwei große klimapolitische Ziele festgelegt: die Senkung der Treibhausgasemissionen um 55% bis zum Jahr 2030 und Treibhausgasneutralität ab dem Jahr 2050. Im Rahmen des EU-Horizon-2020-Projekts ENTRANCES werden die gesellschaftlichen Effekte der Dekarbonisierung und besonders des Kohleausstiegs in verschiedenen europäischen Regionen interdisziplinär analysiert und darauf basierend Handlungsempfehlungen für die Politik abgeleitet. Der vorliegende Beitrag stellt erste analytische Ergebnisse vor.

Frühkindliche Betreuung erhöht den Arbeitsmarkterfolg von Müttern ohne Abitur
Henning Hermes, Marina Krauß, Philipp Lergetporer, Frauke Peter, Simon Wiederhold
Wirtschaft im Wandel,
Nr. 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.

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.

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.

Early Child Care and Labor Supply of Lower-SES Mothers: A Randomized Controlled Trial
Henning Hermes, Marina Krauss, Philipp Lergetporer, Frauke Peter, Simon Wiederhold
CESifo Working Paper,
Nr. 10178,
2022
Abstract
We present experimental evidence that enabling access to universal early child care for families with lower socioeconomic status (SES) increases maternal labor supply. Our intervention provides families with customized help for child care applications, resulting in a large increase in enrollment among lower-SES families. The treatment increases lower-SES mothers' full-time employment rates by 9 percentage points (+160%), household income by 10%, and mothers' earnings by 22%. The effect on full-time employment is largely driven by increased care hours provided by child care centers and fathers. Overall, the treatment substantially improves intra-household gender equality in terms of child care duties and earnings.

Identifying Rent-sharing Using Firms' Energy Input Mix
Matthias Mertens, Steffen Müller, Georg Neuschäffer
IWH Discussion Papers,
Nr. 19,
2022
Abstract
We present causal evidence on the rent-sharing elasticity of German manufacturing firms. We develop a new firm-level Bartik instrument for firm rents that combines the firms‘ predetermined energy input mix with national energy carrier price changes. Reduced-form evidence shows that higher energy prices depress wages. Instrumental variable estimation yields a rent-sharing elasticity of approximately 0.20. Rent-sharing induced by energy price variation is asymmetric and driven by energy price increases, implying that workers do not benefit from energy price reductions but are harmed by price increases. The rent-sharing elasticity is substantially larger in small (0.26) than in large (0.17) firms.

On Modeling IPO Failure Risk
Gonul Colak, Mengchuan Fu, Iftekhar Hasan
Economic Modelling,
April
2022
Abstract
This paper offers a novel framework, combining firm operational risk, IPO pricing risk, and market risk, to model IPO failure risk. By analyzing nearly a thousand variables, we observe that prior IPO failure risk models have suffered from a major missing-variable problem. Evidence reveals several key new firm-level determinants, e.g., the volatility operating performance, the size of its accounts payable, pretax income to common equity, total short-term debt, and a few macroeconomic variables such as treasury bill rate, and book-to-market of the DJIA index. These findings have major economic implications. The total value loss from not predicting the imminent failure of an IPO is significantly lower with this proposed model compared to other established models. The IPO investors could have saved around $18billion over the period between 1994 and 2016 by using this model.

Financing Choice and Local Economic Growth: Evidence from Brazil
Iftekhar Hasan, Thiago Christiano Silva, Benjamin Miranda Tabak
Journal of Economic Growth,
Nr. 3,
2021
Abstract
We study how financing non-traditional local activities, conceived here as a proxy for activity diversification, is associated with economic growth. We use municipality-level data from Brazil, a country with large geographical, social, and economic disparities observed across its more than 5500 municipalities. We find that finance to non-traditional local activities associates with higher municipal economic growth, suggesting a positive externality between the non-traditional and traditional sectors. Using large natural disasters in Brazil as sources of unexpected negative events, we find that this association between financing non-traditional local activities and economic growth becomes negative in times of distress. We find that traditional local sectors are more affected than non-traditional sectors following a natural disaster. Precisely because of the non-traditional sector’s dependence on the traditional sector, our results suggest that municipalities should restrengthen their traditional activities during adverse conditions.
