Locked in a Fossil-Centric System Paradigm: LNG Expansion Impedes Socio-Ecological Transition Toward a Just and Renewable Energy Future

The expansion of liquefied natural gas (LNG) infrastructure in Europe significantly impedes the necessary socio-ecological transformation (SET) required to shift toward a decentralized, 100% renewable energy system (RES). By reinforcing a fossil-centric system paradigm, LNG infrastructure deepens Europe’s dependence on fossil fuels, thereby delaying climate goals and increasing greenhouse gas emissions. ...

Strukturwandel in den Regionen: Was sich ändert und wie die Politik reagieren sollte

In Germany, the structural shift away from industry has long been much slower than in other similarly developed countries. Now, it is increasingly being shaped by global megatrends such as digitisation, decarbonisation, demographic change and changing international economic relations. There are significant regional differences in the adaptation processes: urban areas benefit from inno¬vation density ...

Arbeitsmarkt im Wandel: Polarisierung, Fachkräfteengpässe und Labour Hoarding

Die deutsche Volkswirtschaft befindet sich aktuell nicht nur in einer konjunkturellangespannten Lage, sondern steht zugleich vor einem tiefgreifenden Strukturwandel –getrieben durch technologische Innovationen, Dekarbonisierung, (De-)Globalisierung – sowiedem demografischen Wandel. Diese Entwicklungen haben weitreichende Auswirkungenauf den Arbeitsmarkt. Der Arbeitsmarkt ist geprägt von einer zunehmenden ...

Home Bias, Sovereign-Bank Nexus and Bank Failure: Evidence from European Stress Tests

This paper proposes a new way to clarify the relationship between the sovereign-bank nexus and an individual bank’s home bias by employing stress test data from Europe’s most important banks. We use the individual bank’s likelihood to fail in achieving a minimum capital ratio threshold as the dependent variable in a cross-sectional logistic regression approach and compute marginal effects. In further ...

Nationwide Population-Based Infection- and Vaccine-Induced SARS-CoV-2 Antibody Seroprevalence in Germany in Autumn/Winter 2021/2022

Background: The first Corona Monitoring Nationwide (RKI-SOEP) study (October 2020−February 2021) found a low pre-vaccine SARS-CoV-2 antibody seroprevalence (2.1%) in the German adult population (≥ 18 years). Aim: The objective of this second RKI-SOEP (RKISOEP- 2) study in November 2021−March 2022 was to estimate the prevalence of SARS-CoV-2-specific antispike and/or anti-nucleocapsid (anti-N) IgG antibodies ...

Does Cognitive Reflection Relate to Preferences and Socioeconomic Outcomes?

Previous studies report associations of cognitive reflection, the ability to avoid intuitive but potentially wrong decisions by switching to a contemplative mindset, with individual preferences, mostly relying on student samples and laboratory settings. We assess the association of cognitive reflection with preferences in the general population and real-world socioeconomic outcomes. Our preregistered ...

Wage Risk and Portfolio Choice: The Role of Correlated Returns

From standard portfolio-choice theory, it is well-understood that background risk, primarily due to wage risk, is one of the central determinants of individuals’ portfolio composition: higher background risk reduces risky investments. However, if background risk is negatively correlated with financial market risk, higher background risk implies a more risky investment. We quantify the influence of ...

The Impact of COVID-19 Government Responses on Remittances in Latin American Countries

Workers' remittances declined sharply as the COVID-19 pandemic spread in the first half of 2020, rebounding in the second half. This paper analyses the impact of containment and economic support measures on remittances sent to Latin America during 2019–2020 using a gravity model estimated with the Poisson pseudo-maximum likelihood estimator (PPML). Results show that containment measures in receiving ...

The Impact of Free Trade Agreements on Middle East and North Africa Exports of Intermediate and Final Goods

This paper is the first to analyse the impact of free trade agreements (FTAs) and the harmonisation of rules of origin (RoO) on Middle East and North African (MENA) countries’ exports differentiating between final and intermediate goods for a global sample of trade partners. Data on exports from four MENA countries (Egypt, Jordan, Morocco and Tunisia) to 61 destinations over the period 1995–2016 are ...

Partial Identification of Structural Vector Autoregressions with Non-Centred Stochastic Volatility

We consider structural vector autoregressions that are identified through stochastic volatility under Bayesian estimation. Three contributions emerge from our exercise. First, we show that a non-centred parameterization of stochastic volatility yields a marginal prior for the conditional variances of structural shocks that is centred on homoskedasticity, with strong shrinkage and heavy tails—unlike ...

Cracking Under Pressure? Gender Role Attitudes Toward Maternal Employment during COVID-19 in Germany

The COVID-19 pandemic posed unprecedented challenges to gender equality, particularly affecting working parents due to disruptions in daycare and school operations. It also impacted labor market opportunities for both men and women. This study investigates shifts in gender role attitudes toward maternal employment in Germany during pandemic lockdowns and subsequent periods of eased restrictions, using ...

Disentangling Structural Change, Servitization, and Skill-Biased Change

This paper analyzes three key labor market trends – structural change, servitization, and skill-biased change – using German data from 1975 to 2017. Through a decomposition analysis, we discern their individual impacts on employment shifts, revealing their distinct roles in the German labor market’s evolution. Servitization and skill-biased change significantly influence employment growth alongside ...

The Persuasiveness of Different Sources of Information on the Decision to Vaccinate: A Cross-Sectional Study in Germany During the Pandemic at the Turn of the Year 2021/2022

Health information about vaccinations is communicated via various sources of information and is crucial for vaccination decisions. Information sources such as interpersonal sources, traditional print and digital media as well as social media offer information about the risks and benefits of vaccination. During health crises such as the COVID-19 pandemic was, some information sources provide hanging ...

Composition of Core Modules and Item Allocation in Split Questionnaire Designs: Impact on Estimates from Imputed Data

An increasing number of social science surveys use split questionnaire designs to reduce questionnaire length, presenting only a subset of several questionnaire modules to each respondent while leaving out others. This approach results in large amounts of planned missing data that necessitates imputation. Research shows that imputation is most effective when each module covers various topics. Yet, ...

Impact of ESG Performance on the Cost of Capital in the Energy, Utilities, and Basic Materials Sectors

This paper explores the presence of an environmental, social, and governance (ESG) premium for firms operating in the energy, utilities, and basic materials sectors. Specifically, we examine the influence of ESG performance on firms’ cost of capital in both debt and equity markets. We apply a measure of the ex ante implied cost of equity and the cost of debt to a global sample of over 24,000 firm-year ...

The Impact of Private Hosting on the Integration of Ukrainian Refugees in Germany

Amid the Ukrainian displacement crisis, private hosting of refugees in Europe has surged, yet its impact on integration remains understudied. This research examines the short- to medium-term effects of private hosting on Ukrainian refugee integration in Germany. Using data from one of the largest non-profit platforms that matches private hosts with refugees, we compare the multidimensional integration ...

Stock Market Participation, Work from Home, and Inequality

Stock market participation among working household heads jumped upwards in 2020 - in Germany by about 25 %. A major cause is the required use of work from home (WfH). We show this by adding WfH to a large set of explanatory variables. Moreover, we implement an instrumental variables estimation based on industry-specific levels of WfH-capacity. The transmission channels seem to work via increased available ...
