How People Know their Risk Preference

People differ in their willingness to take risks. Recent work found that revealed preference tasks (e.g., laboratory lotteries)—a dominant class of measures—are outperformed by survey-based stated preferences, which are more stable and predict real-world risk taking across different domains. How can stated preferences, often criticised as inconsequential “cheap talk,” be more valid and predictive than ...

Tuition Fees and Educational Attainment

Following a landmark ruling by the Constitutional Court in 2005, more than half of Germany’s universities started charging tuition fees, which also applied to incumbent students. We exploit this unusual lack of grandfathering together with register data covering the universe of students to show that tuition fees increased degree completion among incumbent students. Investigating mechanisms, we do not ...

Call for Proposals: Possibilities for Analyzing Data from the Survey “The Spread of the Coronavirus in Germany: Socio-Economic Factors and Consequences” (SOEP-CoV)

From April to June 2020, the SOEP conducted the survey “The Spread of the Coronavirus in Germany: Socio-Economic Factors and Consequences” (SOEP-CoV) in cooperation with the University of Bielefeld and funded by the German Federal Ministry of Education and Research (BMBF) (for a description of the methodology in German, see: https://ojs.ub.uni-konstanz.de/srm/article/view/7748 ). For SOEP-CoV, ...

SOEP-Transfer: Research Data for Journalists and Contemporary Historians

The Socio-Economic Panel (SOEP) is the largest and longest-running longitudinal survey of households in Germany. Every year as part of the annual SOEP survey, around 30,000 individuals in 15,000 households provide comprehensive data on their social and economic conditions. The survey data are used by researchers worldwide. The project SOEP-Transfer (scientific project name: “Sharing knowledge and...

Life-course Income Dynamics (LINDY)

Concerns about inequality and questions of social justice and cohesion have re-entered the public arena and animate debate, provoked by the recent rapid increases in cross-sectional inequality. While much has been learnt from the literature on inequality, Deaton (2015) has outlined in his Nobel lecture several imperatives that are key to understanding inequalities and formulating welfare-enhancing...

Virtual Seminar: The international politics of carbon pricing and deep decarbonization

With the Green Deal, the EU aims not only at climate neutrality by 2050, but also to stimulate economic recovery in light of the pandemic. The European Commission is currently revisiting its climate policy instruments in order to strengthen the economics of climate friendly activities and investments. A central part of the debate is the European Emission Trading System and a proposed Carbon Border...

Are stranded assets still stranded? The effect of energy-security debates on redundant infrastructure

Until the Russian war in Ukraine and its strong effects on the re-organisation of energy flows in Europe, it seemed a consensus that fossil assets will become stranded within the coming decades due to ever more stringent climate policy. Therefore, investments in such assets should be avoided as early as possible. With the newly awakened focus on energy security, the insurance aspect of redundant...

Covid-19: A Crisis of the Female Self-Employed

We investigate how the economic consequences of the pandemic, and of the government-mandated measures to contain its spread, affected the self-employed relative to employed individuals in Germany and, secondly, to what extent the female self-employed were more strongly hit than their male counterparts. For our analysis, we use representative real-time survey data in which respondents were asked about ...

Pipes, Taps and Vendors: An Integrated Water Management Approach

This paper applies a microeconomic-based stylized model to identify the optimal modal split of water supply infrastructure in regions of the Global South against the background of the Sustainable Development Goal (SDG) No. 6. We assume a linear city, with some plausible assumptions on income and willingness-to-pay, and then calculate the optimal tap density, leading in turn to an optimal modal split ...
