DIW Discussion Papers 2122 / 2025
The Deutschlandticket, introduced in May 2023, offers unlimited travel on all regional public transport in Germany for 49€ per month. This paper provides an overview of how the intro-duction of the ticket influenced travel behaviour and mode choice based on the GIM Traces panel, a nationwide representative dataset combining GPS tracking data and survey re-sponses. The data, consisting of almost 4 million ...

This project examines the French academic pipeline to identify when and why women become underrepresented in faculty positions: I investigate whether they are less likely to apply, less likely to succeed or a combination of both. Using comprehensive administrative data combining Thèses.fr doctoral records and administrative data from the Conseil National des Universités (CNU), I analyze gender...

During the 2022 energy crisis, electricity prices across Europe have risen to unprecedented heights. In a case study for Germany, this work investigates to which extent price spikes can be attributed to changes in upstream commodity prices, and to which degree strategic behavior by generators may have contributed to the situation. Electricity markets are more prone to the effects of such behavior if ...

Cluster-Seminar Öffentliche Finanzen und Lebenslagen
As Western populations age, more adult children face parental health challenges. Caregiving responsibilities towards parents are becoming crucial concerns for families, healthcare systems, and societies. While this care is essential for elderly well-being, it also demands significant time, energy and emotional resources. Yet, the impact of care provision on caregivers’ lives remains understudied....

Die Umstellung von fossilen Brennstoffen auf erneuerbare Energien ist essenziell, um Klimaneutralität zu erreichen. Da das Potenzial steuerbarer erneuerbarer Energien in den meisten Ländern begrenzt ist, werden zukünftige Energiesysteme voraussichtlich überwiegend mit Strom aus fluktuierender Wind- und Solarenergie betrieben. Der Ausgleich zwischen Stromnachfrage und wetterabhängiger, variabler Erzeugung ...

DIW Discussion Papers 2120 / 2025
This paper provides causal evidence on the effect of credit crunches on political polarisation. Combining data on bank-firm connections and electoral outcomes at the city-level during the 2008-2014 Spanish financial crisis, I construct an instrument for unemployment based on the city-level exposure to (foreign) weak banks. I find that a 10% increase in (instrumented) local unemployment rates leads ...

DIW Discussion Papers 2121 / 2025
This study examines how policies affecting the cost of using fossil fuels in production influence comparative advantage in the industrial sector. Firstly, we use a fixed-effects gravity model to estimate the export capabilities that determine comparative advantage. Subsequently, using data on direct (carbon taxes, ETS permit prices) and indirect (fossil fuel excise taxes and subsidies) carbon pricing ...
