We show that the incentives for customer and input foreclosure can be higher, equal, or even lower with partial ownership than with a vertical merger, depending on how the protection of minority shareholders and transfer price regulations affect the scope for profit extraction.}, language = {en} } @techreport{Leichthammer, type = {Working Paper}, author = {Leichthammer, Arthur}, title = {Mining for Tomorrow: The strategic importance of critical raw materials for Europe's industry}, pages = {6}, abstract = {Arthur Leichthammer, Geoeconomics Policy Fellow at the Jacques Delors Centre, argues that the EU needs a strategic rethink to safeguard its critical raw materials supplies as global competition intensifies.}, language = {en} } @techreport{Quaritsch, type = {Working Paper}, author = {Quaritsch, Luise}, title = {Political Advertising in the 2024 European elections - Between Europeanisation and the protection of electoral integrity online}, pages = {8}, abstract = {Election campaigns are increasingly conducted online. Social media platforms in particular shape political discourse and facilitate new ways of delivering political messages. This was initially considered a boon for democracy, but opaque manipulation tactics quickly turned it into a threat to fair and transparent elections. National regulatory frameworks have often proved to be inadequate for online campaigns and the transnational nature of European elections. The EU has reacted to this with a regulation on political advertising. The initiative facilitates transnational campaigning online and aims to protect the integrity of European elections. The 2024 European elections will be the first time EU rules operate in this area, putting these to the test. This election cycle will indicate whether political actors are striking out for more cross-border campaigns and whether they suffice to protect European elections. Critical here is how online platforms implement the new rules and how transparent they are about campaign-related posts on their sites.}, language = {en} } @techreport{Shahini, type = {Working Paper}, author = {Shahini, Besa}, title = {Towards Enlargement - How to Rebuild Trust in the EU Accession Process}, pages = {8}, abstract = {EU enlargement has historically fostered economic growth and political stability. In the Western Balkans, however, the process has stalled for many years due to the myriad crises afflicting the EU and failure to deliver reforms in the Western Balkans. This policy brief examines the evolution of the EU accession process, the challenges faced by candidate countries, and the need for a revitalized approach that builds reforms into the accession process rather than keep them a precondition for kickstarting it. It calls for the EU to remove bilateral disputes from the process and open accession talks with all candidate countries in all areas covered by the acquis, ensuring that all candidate countries have a fair chance based on their merits.}, language = {en} } @phdthesis{Lohse, author = {Lohse, Anna Prisca}, title = {Higher Education in an Age of Disruption: Comparing European Internationalisation Policies}, publisher = {Palgrave Macmillan}, address = {Cham}, isbn = {9783031579110}, doi = {10.1007/978-3-031-57912-7}, school = {Hertie School}, pages = {XXIV, 338}, abstract = {This book investigates European higher education internationalisation policies during a period marked by extreme upheaval due to Brexit and the COVID-19 pandemic. Situating her analysis at the intersection of higher education research and policy studies, the author combines historical and sociological institutionalism to investigate how this time of disruption impacted higher education policies in England, France and Germany. Based on extensive qualitative data derived from expert interviews and document analysis, the study offers timely insights into dynamics of institutional change and stability in higher education governance, as well as implications for the future of cross-border education and internationalisation.

As the share of consumption that is exposed to real-time prices (currently less than 25\%) expands, we expect the aggregated price elasticity to grow.}, language = {en} } @incollection{KreyenfeldSchmauckMika, author = {Kreyenfeld, Michaela and Schmauck, Sarah and Mika, Tatjana}, title = {Der Wandel der Lebensformen und seine Bedeutung f{\"u}r die Alterssicherung in Deutschland}, series = {Gerechte Rente: Sozialethische Perspektiven einer interdisziplin{\"a}ren Sondierung der Alterssicherung}, booktitle = {Gerechte Rente: Sozialethische Perspektiven einer interdisziplin{\"a}ren Sondierung der Alterssicherung}, editor = {Karger-Kroll, Anna and Sch{\"a}fers, Lars}, publisher = {Nomos}, isbn = {978-3-7560-1712-6}, publisher = {Hertie School}, language = {de} } @article{AllcottGentzkowMasonetal., author = {Allcott, Hunt and Gentzkow, Matthew and Mason, Winter and Wilkins, Arjun and Barber{\´a}, Pablo and Brown, Taylor and Cisneros, Juan Carlos and Crespo-Tenorio, Adriana and Dimmery, Drew and Freelon, Deen and Gonz{\´a}lez-Bail{\´o}n, Sandra and Guess, Andrew M. and Kim, Young Mie and Lazer, David and Malhotra, Neil and Moehler, Devra and Nair-Desai, Sameer and Nait El Barj, Houda and Nyhan, Brendan and Paixao de Queiroz, Ana Carolina and Pan, Jennifer and Settle, Jaime and Thorson, Emily and Tromble, Rebekah and Velasco Rivera, Carlos and Wittenbrink, Benjamin and Wojcieszak, Magdalena and Zahedian, Saam and Franco, Annie and Kiewiet de Jonge, Chad and Stroud, Natalie Jomini and Tucker, Joshua A.}, title = {The effects of Facebook and Instagram on the 2020 election: A deactivation experiment}, series = {Proceedings of the National Academy of Sciences}, volume = {121}, journal = {Proceedings of the National Academy of Sciences}, number = {21}, doi = {10.1073/pnas.2321584121}, abstract = {We study the effect of Facebook and Instagram access on political beliefs, attitudes, and behavior by randomizing a subset of 19,857 Facebook users and 15,585 Instagram users to deactivate their accounts for 6 wk before the 2020 U.S. election. We report four key findings. First, both Facebook and Instagram deactivation reduced an index of political participation (driven mainly by reduced participation online). Second, Facebook deactivation had no significant effect on an index of knowledge, but secondary analyses suggest that it reduced knowledge of general news while possibly also decreasing belief in misinformation circulating online. Third, Facebook deactivation may have reduced self-reported net votes for Trump, though this effect does not meet our preregistered significance threshold. Finally, the effects of both Facebook and Instagram deactivation on affective and issue polarization, perceived legitimacy of the election, candidate favorability, and voter turnout were all precisely estimated and close to zero.}, language = {en} } @techreport{StieweXuEickeetal., type = {Working Paper}, author = {Stiewe, Clemens and Xu, Alice Lixuan and Eicke, Anselm and Hirth, Lion}, title = {Cross-border cannibalization: Spillover effects of wind and solar energy on interconnected European electricity markets}, publisher = {arXiv}, doi = {10.48550/arXiv.2405.17166}, pages = {25}, abstract = {The average revenue, or market value, of wind and solar energy tends to fall with increasing market shares, as is now evident across European electricity markets. At the same time, these markets have become more interconnected. In this paper, we empirically study the multiple cross-border effects on the value of renewable energy: on one hand, interconnection is a flexibility resource that allows to export energy when it is locally abundant, benefitting renewables. On the other hand, wind and solar radiation are correlated across space, so neighboring supply adds to the local one to depress domestic prices. We estimate both effects, using spatial panel regression on electricity market data from 2015 to 2023 from 30 European bidding zones. We find that domestic wind and solar value is not only depressed by domestic, but also by neighboring renewables expansion. The better interconnected a market is, the smaller the effect of domestic but the larger the effect of neighboring renewables. While wind value is stabilized by interconnection, solar value is not. If wind market share increases both at home and in neighboring markets by one percentage point, the value factor of wind energy is reduced by just above 1 percentage points. For solar, this number is almost 4 percentage points.}, language = {en} }
