Fact Boxes that Inform Individual Decisions May Contribute to a More Positive Evaluation of COVID-19 Vaccinations at the Population Level

ObjectiveFor an effective control of the SARS-CoV-2 pandemic with vaccines, most people in a population need to be vaccinated. It is thus important to know how to inform the public with reference to individual preferences–while also acknowledging the societal preference to encourage vaccinations. According to the health care standard of informed decision-making, a comparison of the benefits and harms ...

Corona Monitoring Nationwide (RKI-SOEP-2): Seroepidemiological Study on the Spread of SARS-CoV-2 Across Germany

SARS-CoV-2, the coronavirus, spread across Germany within just a short period of time. Seroepidemiological studies are able to estimate the proportion of the population with antibodies against SARS-CoV-2 infection (seroprevalence) as well as the level of undetected infections, which are not captured in official figures. In the seroepidemiological study Corona Monitoring Nationwide (RKI-SOEP-2), biospecimens ...

The Effect of Unemployment on Care Provision

In this paper we estimate the effect of unemployment on informal care provision. For the identification we use plant closures as a source of exogenous variation and combine difference-in-differences with matching based on entropy balancing. The analysis is based on data from the German Socio-Economic Panel (SOEP). We find that there is a time conflict between employment and informal care provision. ...

Big Five Personality and Religiosity: Bidirectional Cross-Lagged Effects and Their Moderation by Culture

Objective: Personality has long been assumed to be a cause of religiosity, not a consequence. Yet, recent research suggests that religiosity may well cause personality change. Consequently, longitudinal research is required that examines the bi-directionality between personality and religiosity. The required research must also attend to cultural religiosity—a critical moderator in previous cross-sectional ...

The Short- and Medium-term Distributional Effects of the German Minimum Wage Reform

This study quantifies the distributional effects of the minimum wage introduced in Germany in 2015. Using detailed Socio-Economic Panel survey data, we assess changes in the hourly wages, working hours, and monthly wages of employees who were entitled to be paid the minimum wage. We employ a difference-in-differences analysis, exploiting regional variation in the “bite” of the minimum wage. At the ...

Ignorance, Intention and Stochastic Outcomes

In sequential interactions, both the agent’s intention and the outcome of his choice may influence the principal’s action. While outcomes are typically observable, intentions are more likely to be hidden, leaving potential wiggle room for the principal when deciding on a reciprocating action. We employ a controlled experiment to investigate how intentions and outcome affect the principal’s actions ...

Crisis Stress for the Diversity of Financial Portfolios - Evidence from European Households

In this paper, we investigate how European households changed the diversity of their financial portfolios in response to the Great Financial and the subsequent European Debt Crisis. For this purpose we apply a Difference-in-Differences (DiD) approach estimated as a correlated random effects (CRE) model to six waves of the Survey of Health, Ageing and Retirement in Europe (SHARE). We find that households ...

From Negative to Positive Carbon Pricing in Mexico

Over the course of a decade, Mexico transitioned from a peak of 1.8% of GDP given as fuel subsidies in 2008 to generating positive fuel tax revenues equivalent to 1.6% of its GDP in 2018. This paper analyzes Mexico's carbon pricing experience: the mechanisms that made fossil fuel subsidies such a large burden on public finances, the strategies followed in its five-year phase-out, and the institutional ...

Multiple Imputation of Ordinal Missing Not at Random Data

We introduce a selection model-based imputation approach to be used within the Fully Conditional Specification (FCS) framework for the Multiple Imputation (MI) of incomplete ordinal variables that are supposed to be Missing Not at Random (MNAR). Thereby, we generalise previous work on this topic which involved binary single-level and multilevel data to ordinal variables. We apply an ordered probit ...

Financing Renewables in the Age of Falling Technology Costs

Cost of renewable energies have dropped, approaching wholesale power price levels. As a result, the role of renewable energy policy design is shifting – from covering incremental costs towards facilitating risk-hedging. An analytical model of the financing structure of renewable investment projects is developed to assess this effect und used to compare different policy design choices: contracts for ...

Carbon Contracts-for-difference: How to De-risk Innovative Investments for a Low-carbon Industry?

The shift to climate neutrality requires new process technologies for energy-intensive industries, such as steel, chemicals, or cement. A variety of technology options exist – but they face the challenges of (i) first-of-kind costs, (ii) higher operation and investment costs, and (iii) insufficient and uncertain carbon prices, which partly stem from political uncertainty. Existing innovation policy ...

Pension Wealth and the Gender Wealth Gap

We examine the gender wealth gap with a focus on pension wealth and statutory pension rights. By taking into account employment characteristics of women and men, we are able to identify the extent to which the redistributive effect of pension rights reduces the gender wealth gap. The data for our analysis come from the German Socio-Economic Panel (SOEP), one of the few surveys that collects information ...

Das Narrativ der unaufhaltsam steigenden Ungleichheit geht an der Lebenswirklichkeit der meisten Menschen vorbei

In diesem Artikel wird diskutiert, warum das weit verbreitete Narrativ einer wachsenden ökonomischen Ungleichheit in Deutschland nicht zu einer Stärkung der entsprechenden politischen Kräfte (SPD, Linkspartei und Gewerkschaften) geführt hat. Der Fokus liegt dabei nicht auf politischen Widerständen und Gegenkräften, die es bezüglich mehr Gleichheit zweifelsohne gab und gibt, sondern auf der Gültigkeit ...

The Transition to Grandparenthood: No Consistent Evidence for Change in the Big Five Personality Traits and Life Satisfaction

Intergenerational relations have received close attention in the context of population aging and increased childcare provision by grandparents. However, few studies have investigated the psychological consequences of becoming a grandparent. In a preregistered test of grandparenthood as a developmental task in middle and older adulthood, we used representative panel data from the Netherlands (N = 563) ...

Too Good to Be True? Time-inconsistent Renewable Energy Policies

The transition to low-carbon economies requires massive investments into renewable energies, which are commonly supported through regulatory frameworks. Yet, governments can have incentives – and the ability – to deviate from previously announced support policies once those investments have been made, which can deter investments. We analyze a renewable energy dynamic regulation game and derive under ...

A Lasting Crisis Affects R&D Decisions of Smaller Firms: The Greek Experience

We use the prolonged Greek crisis as a case study to understand how a lasting economic shock affects the innovation strategies of firms in economies with moderate innovation activities. Adopting the 3-stage CDM model, we explore the link between R&D, innovation, and productivity for different size groups of Greek manufacturing firms during the prolonged crisis. At the first stage, we find that the ...

Knappes Gas – Optionen zur Verringerung der Deckungslücke in Deutschland

In this article, we provide the results of a simple quantitative analysis of the potential remedies to reduce the supply gap in Germany that arises if Russia stops delivering natural gas. We take into account the supply potential of other suppliers, and combine this with an analysis of the additional supply potential by stopping electricity generation from natural gas. Moreover, we investigate the ...

Accounting for Spatiality of Renewables and Storage in Transmission Planning

The current governance process to plan the German energy system omits two options to substitute grid expansion: First, placing renewables closer to demand instead of where site conditions are best. Second, utilizing storage instead of additional transmission infrastructure to prevent grid congestion. In the paper, we apply a comprehensive capacity expansion model based on the AnyMOD modeling framework ...

The Gender Division of Unpaid Care Work throughout the COVID-19 Pandemic in Germany

The COVID-19 pandemic and related closures of day care centres and schools significantly increased the amount of care work done by parents. There has been much speculation over whether the pandemic increased or decreased gender equality in parental care work. Based on representative data for Germany from spring 2020 and winter 2021 we present an empirical analysis that shows that although gender inequality ...
