The Elephant in the Room: How Do We Regulate Gas Transportation Infrastructure as Gas Demand Declines? Commentary

The use of gas will decline dramatically as part of the transition to net zero. Modeling at European levelsshows that by 2050 about 70% less gaseous fuels will be used. Significant regulatory reform is needed todeal with the impacts of this decline on the gas grid.

Realizing the Value of Recycling – Assessing the Elements of a Policy Package

We investigate policies for increasing recycling to facilitate decarbonization within the basic material sector, including market-based policies, such as carbon pricing, advanced disposal fee and minimum recycled content requirement, and non-market policies, such as product design standard. We develop an analytical model to assess the role of these policy instruments for recycling related choices of ...

The Effect of Pension Wealth on Employment

This study provides novel evidence about the pension wealth elasticity of employment. For the identification we exploit reform-induced variation of pension wealth that is related to the number of children but which does not affect the implicit tax rate of employment. We use a difference-in-differences estimator based on administrative data from the German pension insurance and find that, on average, ...

Data Fusion to Compensate for Insufficient Survey Coverage: Example of the German National PKT-Model

This paper presents a data fusion approach combining German National Travel Survey data with aggregate transport indicators such as passenger counts in order to generate annual passenger kilometers travelled (PKT) for the German National Transport Statistics. To cover all travel adequately, the model combines two MiD data sets (a 24-hour-trip diary and an overnight journey questionnaire) and includes ...

The Long Way to Tax Transparency: Lessons from the Early Publishers of Country-by-Country Reports

In this paper, we analyse a sample of voluntarily published country-by-country reports (CbCRs) of 35 multinational enterprises (MNEs). We assess the value added and the limitations of qualitative and quantitative information provided in the reports based on a comparison to individual MNEs’ annual financial reports and aggregate CbCR data provided by the OECD. In terms of data quality, we find that ...

Restrictions to Civil Liberties in a Pandemic and Satisfaction with Democracy

In times of crises, democracies face the challenge of balancing effective interventions with civil liberties. This study examines German states’ response during the early stages of the COVID-19 pandemic, focusing on the interplay between civil liberties and public health goals. Using state-level variation in mobility restrictions, we employ a difference-in-differences design to show that stay-at-home ...

The Effect of Migration on Careers of Natives: Evidence from Long-term Care

This paper examines the effect of increasing foreign staffing on the labor market outcomes of native workers in the German long-term care sector. Using administrative social security data covering the universe of long-term care workers and policy-induced exogenous variation, we find that increased foreign staffing reduces labor shortages but has diverging implications for the careers of native workers ...

A Linear Reduced-Order Model for the Activated Sludge Process for the Integration into a Mixed-Integer Linear Energy System Optimisation Model

Conventional wastewater treatment plants consume significant amounts of electricity. The constant aeration of the wastewater in order to foster the growth of microorganisms or the pumping of wastewater are two examples for energy-intensive processes within a plant. Case studies have shown that switching off blowers and inlet pumps for a certain period of time is possible without a loss in water quality. ...

SOEP-IS: Selection of promising new modules – 2024 call for submissions suspended

Last year, the SOEP innovation sample (SOEP-IS) received numerous proposals for new and innovative modules. After selecting the best modules, we are pleased to report that we were able to significantly expand the potential of the data. The SOEP-IS team is currently conducting an exceptionally high number of inspiring projects, collaborations, and longitudinal innovation modules. Due to the many new ...
