GEG-Novellierung: Das „Heizungsgesetz“ und die Bundestagswahl 2025
No full textDas Gebäudeenergiegesetz (GEG), umgangssprachlich auch „Heizungsgesetz“ genannt, sorgte in den letzten Jahren für viele Diskussionen in Öffentlichkeit, Medien und Politik. Die meisten Zeitungen berichteten ausgiebig über den Entwurf der GEG-Novellierung, wobei er überwiegend negativ bewertet wurde. Während die Zufriedenheit mit dem Spitzenpersonal aller Koalitionspartner insgesamt zurückging, sanken die Beliebtheitswerte des damaligen Wirtschaftsministers Robert Habeck (Grüne) am stärksten. Diese Entwicklungen ließen viele Analyst/innen in Medien und Wissenschaft zu dem Schluss kommen, dass die negative Berichterstattung hauptsächlich den Grünen geschadet hat. In dieser Kurzanalyse testen wir die Hypothese, ob insbesondere die Grünen aufgrund der GEG-Novellierung Wählerstimmen verloren haben. Wir kommen zu dem Ergebnis, dass sowohl Grüne als auch SPD in westdeutschen Gemeinden mit höherem Anteil an fossilen Heizungen höhere Stimmenverluste hatten. Die Grünen verloren jedoch etwas weniger stark als die SPD. In ostdeutschen Gemeinden änderten sich die Stimmanteile der Parteien der Mitte nicht signifikant. Die Parteien an den Rändern des politischen Spektrums profitierten (AfD im „Osten“, Linke im „Westen“). Insgesamt ist der Zusammenhang zwischen dem Anteil an fossilen Heizungen und Stimmenverlusten eher schwach und kann den Verlust der Grünen bei den Wahlen nicht erklären

No full textThis thesis explores how individuals, firms and policymakers make decisions that influence climate-relevant technology uptake and behavioral change. Chapter 1 evaluates a novel lending model in rural Pakistan that combines loans for solar systems with a novel index insurance scheme, which lowers repayments during periods of low electricity production. Using a randomized controlled trial with over 1,500 entrepreneurs, the study finds that the insurance increases solar adoption, reduces electricity spending, and improves welfare. Chapter 2 investigates how Fridays for Future protests affect household behavior in the U.S., showing that only households with young individuals temporarily reduce meat consumption after nearby protests, while others do not. Chapter 3 analyzes municipal subsidy programs for plug-in photovoltaic systems in Germany, demonstrating that subsidies causally boost installations. By exploring the granularity of the programs, this chapter demonstrates that their effectiveness could have been increased by offering higher upfront payments without raising the overall program cost

No full textKnowing what I don’t know – belief in conspiracy theories relates to lower metacognitive sensitivity: a signal detection theoretic approach
Full text linkDescription
Beliefs in conspiracy theories are seemingly hard to dispute through facts. Researchers have partly attributed this resistance to certain information processing styles that are associated with conspiracy beliefs. Previous research therein has extensively examined the role of object-level information processing, for instance, intuitive (vs. analytic) thinking and cognitive reflection. However, research has so far has not considered that conspiracy beliefs might also be related to different ways of metacognitive information processing. In two studies, one sample from Germany, one quota-based sample from the US (total N = 1,231), we show that a generic belief in conspiracy theories as well as the belief in specific conspiracy theories such as those surrounding vaccinations and QAnon (but less so conspiracy mentality) is related to lower metacognitive sensitivity – i.e. a lower ability to accurately evaluate one’s knowledge. Results hold when controlling for object-level knowledge, cognitive reflection, and intuitive thinking
Firms' disclosure of university ties on their website: An explorative analysis of its role for innovation performance
Full text linkThis paper explores a novel web-based indicator to examine how firms’ disclosure of university ties on their websites shapes their innovation performance. First, using data from the German Community Innovation Survey 2023 and the Tenders Electronic Daily database, combined with firms’ discloser of university ties on their website provided by ISTARI.AI, we investigate the indicator’s properties by comparing the most frequently disclosed types of university ties: innovation collaborations, university customers, and employee education, with firms’ survey responses and their procurement contracts. Second, we analyze how website disclosure of university ties relates to firms’ revenues from new or significantly improved products or services, applying Ordinary Least Squares, a Control Function, and Lewbel Instrumental Variable approach. In sum, the website disclosure of ties with universities is significantly associated with its related survey items and procurement contracts. Moreover, website disclosures show no consistent association with revenues from innovations new-to-the-firm. A consistent statistically significant relationship emerges only for small firms, where website disclosures are associated with higher revenues from market novelties. These findings suggest that our web-based indicator captures ties between firms and universities and that disclosing these ties on firms’ websites may influence the market success of their novel products
